3 === This file documents the new and/or enhanced functionality added in
4 === the Asterisk versions listed below. This file does NOT include
5 === changes in behavior that would not be backwards compatible with
6 === previous versions; for that information see the UPGRADE.txt file
7 === and the other UPGRADE files for older releases.
9 ==============================================================================
11 ------------------------------------------------------------------------------
12 --- Functionality changes from Asterisk 10 to Asterisk 11 --------------------
13 ------------------------------------------------------------------------------
17 * The expression parser now recognizes the ABS() absolute value function,
18 which will convert negative floating point values to positive values.
19 * The Asterisk build system will now build and install a shared library
20 (libasteriskssl.so) used to wrap various initialization and shutdown functions
21 from the libssl and libcrypto libraries provided by OpenSSL. This is done so
22 that Asterisk can ensure that these functions do *not* get called by any
23 modules that are loaded into Asterisk, since they should only be called once
24 in any single process. If desired, this feature can be disabled by supplying
25 the "--disable-asteriskssl" option to the configure script.
29 * mixmonitor list <channel> command will now show MixMonitor ID, and the filenames
30 of all running mixmonitors on a channel.
31 * The debuglevel of "pri set debug" is now a bitmask ranging from 0 to 15 if
32 numeric instead of 0, 1, or 2.
36 * Added menu action admin_toggle_mute_participants. This will mute / unmute
37 all non-admin participants on a conference. The confbridge configuration file
38 also allows for the default sounds played to all conference users when this
39 occurs to be overriden using sound_participants_unmuted and sound_participants_muted.
40 * Added menu action participant_count. This will playback the number of current
41 participants in a conference.
45 * Addition of the VM_INFO function - see Dialplan function changes
46 * The imapserver, imapport, and imapflags configuration options can now be
47 overriden on a user by user basis.
51 * Asterisk will no longer substitute CID number for CID name into display
52 name field if CID number exists without a CID name. This change improves
53 compatibility with certain device features such as Avaya IP500's directory
55 * A new setting for autocreatepeer (autocreatepeer=persistent) allows peers
56 created using that setting to not be removed during SIP reload.
57 * Add support to realtime for the 'callbackextension' option
58 * When multiple peers exist with the same address, but differing
59 callbackextension options, incoming requests that are matched by address
60 will be matched to the peer with the matching callbackextension if it is
62 * NAT settings are now a combinable list of options. The equivalent of the
63 deprecated nat=yes is nat=force_rport,comedia. nat=no behaves as before.
64 * Two new NAT options, auto_force_rport and auto_comedia, have been added
65 which set the force_rport and comedia options automatically if Asterisk
66 detects that an incoming SIP request crossed a NAT after being sent by
71 * Added a manager event "LocalBridge" for local channel call bridges between
72 the two pseudo-channels created.
76 * Codec lists may now be modified by the '!' character, to allow succinct
77 specification of a list of codecs allowed and disallowed, without the
78 requirement to use two different keywords. For example, to specify all
79 codecs except g729 and g723, one need only specify allow=all,!g729,!g723.
83 * Added 'announcement' option which will play at the start of MOH and between
84 songs in modes of MOH that can detect transitions between songs (eg.
89 * Added queue options autopausebusy and autopauseunavail for automatically
90 pausing a queue member when their device reports busy or congestion.
94 * When voicemail plays a message's envelope with saycid set to yes, when reaching
95 the caller id field it will play a recording of a file with the same base name
96 as the sender's callerid if there is a similarly named file in
97 <astspooldir>/recordings/callerids/
101 * Added 'j' option to SayUnixTime. SayUnixTime no longer auto jumps to extension
102 when receiving DTMF. Use the 'j' option to enable extension jumping. Also
103 changed arguments to SayUnixTime so that every option is truly optional even
104 when using multiple options (so that j option could be used without having to
105 manually specify timezone and format) There are other beneftis eg. format can
106 now be used without specifying time zone as well.
110 * New per parking lot options: comebackcontext and comebackdialtime. See
111 configs/features.conf.sample for more details.
113 * Channel variable PARKER is now set when comebacktoorigin is disabled in
116 * MixMonitor hooks now have IDs associated with them which can be used to assign
117 a target to StopMixMonitor. Use of MixMonitor's i(variable) option will allow
118 storage of the MixMontior ID in a channel variable. StopMixmonitor now accepts
119 that ID as an argument.
121 CDR postgresql driver changes
122 -----------------------------
123 * Added command "cdr show pgsql status" to check connection status
125 AMI (Asterisk Manager Interface) changes
126 ----------------------------------------
127 * Originate now generates an error response if the extension given
128 is not found in the dialplan
130 * MixMonitor will now show IDs associated with the mixmonitor upon creating them
131 if the i(variable) option is used. StopMixMonitor will accept MixMonitorID as
132 on option to close specific MixMonitors.
134 * The SIPshowpeer manager action response field "SIP-Forcerport" has been updated
135 to include information about peers configured with nat=auto_force_rport by
136 returning "A" if auto_force_rport is set and nat is detected, and "a" if it is
137 set and nat is not detected. "Y" and "N" are still returned if auto_force_rport
142 * FAXOPT(faxdetect) will enable a generic fax detect framehook for dialplan
143 control of faxdetect.
147 * Allow the built in variables ${NUMBER}, ${IPADDR} and ${SECRET} to be
148 used within the dynamic weight attribute when specifying a mapping.
152 * Addition of the VM_INFO function that can be used to retrieve voicemail
153 user information, such as the email address and full name.
154 The MAILBOX_EXISTS dialplan function has been deprecated in favour of
159 * A new option, 'I' has been added to app_followme.
160 By setting this option, Asterisk will not update the caller with
161 connected line changes when they occur. This is similar to app_dial
163 * The 'N' option is now ignored if the call is already answered.
167 * A new option, 'probation' has been added to rtp.conf
168 RTP in strictrtp mode can now require more than 1 packet to exit learning
169 mode with a new source (and by default requires 4). The probation option
170 allows the user to change the required number of packets in sequence to any
171 desired value. Use a value of 1 to essentially restore the old behavior.
172 Also, with strictrtp on, Asterisk will now drop all packets until learning
173 mode has successfully exited. These changes are based on how pjmedia handles
174 media sources and source changes.
178 * MESSAGE(from) for incoming SIP messages now returns "display-name" <uri>
179 instead of simply the uri. This is the format that MessageSend() can use
180 in the from parameter for outgoing SIP messages.
184 * A new module, res_corosync, has been introduced. This module uses the
185 Corosync cluster enginer (http://www.corosync.org) to allow a local cluster
186 of Asterisk servers to both Message Waiting Indication (MWI) and/or
187 Device State (presence) information. This module is very similar to, and
188 is a replacement for the res_ais module that was in previous releases of
193 * A new channel variable, AGIEXITONHANGUP, has been added which allows
194 Asterisk to behave like it did in Asterisk 1.4 and earlier where the
195 AGI application would exit immediately after a channel hangup is detected.
197 ------------------------------------------------------------------------------
198 --- Functionality changes from Asterisk 1.8 to Asterisk 10 -------------------
199 ------------------------------------------------------------------------------
203 * Asterisk now has protocol independent support for processing text messages
204 outside of a call. Messages are routed through the Asterisk dialplan.
205 SIP MESSAGE and XMPP are currently supported. There are options in
206 jabber.conf and sip.conf to allow enabling these features.
207 -> jabber.conf: see the "sendtodialplan" and "context" options.
208 -> sip.conf: see the "accept_outofcall_message", "auth_message_requests"
209 and "outofcall_message_context" options.
210 The MESSAGE() dialplan function and MessageSend() application have been
211 added to go along with this functionality. More detailed usage information
212 can be found on the Asterisk wiki (http://wiki.asterisk.org/).
213 * If real-time text support (T.140) is negotiated, it will be preferred for
214 sending text via the SendText application. For example, via SIP, messages
215 that were once sent via the SIP MESSAGE request would be sent via RTP if
216 T.140 text is negotiated for a call.
220 * parkedmusicclass can now be set for non-default parking lots.
222 Asterisk Manager Interface
223 --------------------------
224 * PeerStatus now includes Address and Port.
225 * Added Hold events for when the remote party puts the call on and off hold
226 for chan_dahdi ISDN channels.
227 * Added new action MeetmeListRooms to list active conferences (shows same
228 data as "meetme list" at the CLI).
229 * DAHDIShowChannels, SIPshowpeer, SIPpeers, and IAXpeers now contains a
230 Description field that is set by 'description' in the channel configuration
232 * Added Uniqueid header to UserEvent.
233 * Added new action FilterAdd to control event filters for the current session.
234 This requires the system permission and uses the same filter syntax as
235 filters that can be defined in manager.conf
236 * The Unlink event is now a Bridge event with Bridgestatus: Unlink. Previous
237 versions had some instances of the event converted, but others were left
238 as-is. All Unlink events should now be converted to Bridge events. The AMI
239 protocol version number was incremented to 1.2 as a result of this change.
242 --------------------------
243 * The HTTP Server can bind to IPv6 addresses.
246 --------------------------
247 * Busy tone patterns featuring 2 silence and 2 tone lengths can now be used
248 with busydetect. usage example: busypattern=200,200,200,600
251 --------------------------
252 * New 'gtalk show settings' command showing the current settings loaded from
254 * The 'logger reload' command now supports an optional argument, specifying an
255 alternate configuration file to use.
256 * 'dialplan add extension' command will now automatically create a context if
257 the specified context does not exist with a message indicated it did so.
258 * 'sip show peers', 'iax show peers', and 'dahdi show peers' now contains a
259 Description field which can be populated with 'description' in the channel
260 configuration files (sip.conf, iax2.conf, and chan_dahdi.conf).
263 --------------------------
264 * The filter option in cdr_adaptive_odbc now supports negating the argument,
265 thus allowing records which do NOT match the specified filter.
266 * Added ability to log CONGESTION calls to CDR
269 --------------------------
270 * Ability to define custom SILK formats in codecs.conf.
271 * Addition of speex32 audio format with translation.
272 * CELT codec pass-through support and ability to define
273 custom CELT formats in codecs.conf.
274 * Ability to read raw signed linear files with sample rates
275 ranging from 8khz - 192khz. The new file extensions introduced
276 are .sln12, .sln24, .sln32, .sln44, .sln48, .sln96, .sln192.
277 * Due to protocol limitations, channel drivers other than SIP (eg. IAX2, MGCP,
278 Skinny, H.323, etc) can still only support the following codecs:
279 Audio: ulaw, alaw, slin, slin16, g719, g722, g723, g726, g726aal2, g729, gsm,
280 siren7, siren14, speex, speex16, ilbc, lpc10, adpcm
281 Video: h261, h263, h263p, h264, mpeg4
286 --------------------------
287 * New highly optimized and customizable ConfBridge application capable of
288 mixing audio at sample rates ranging from 8khz-96khz.
289 * CONFBRIDGE dialplan function capable of creating dynamic ConfBridge user
290 and bridge profiles on a channel.
291 * CONFBRIDGE_INFO dialplan function capable of retrieving information
292 about a conference such as locked status and number of parties, admins,
294 * Addition of video_mode option in confbridge.conf for adding video support
295 into a bridge profile.
296 * Addition of the follow_talker video_mode in confbridge.conf. This video
297 mode dynamically switches the video feed to always display the loudest talker
298 supplying video in the conference.
302 * Added ASTETCDIR, ASTMODDIR, ASTVARLIBDIR, ASTDBDIR, ASTKEYDIR, ASTDATADIR,
303 ASTAGIDIR, ASTSPOOLDIR, ASTRUNDIR, ASTLOGDIR which hold the equivalent
304 variables from asterisk.conf.
308 * Addition of the JITTERBUFFER dialplan function. This function allows
309 for jitterbuffering to occur on the read side of a channel. By using
310 this function conference applications such as ConfBridge and MeetMe can
311 have the rx streams jitterbuffered before conference mixing occurs.
312 * Added DB_KEYS, which lists the next set of keys in the Asterisk database
314 * Added STRREPLACE function. This function let's the user search a variable
315 for a given string to replace with another string as many times as the
316 user specifies or just throughout the whole string.
317 * Added option to CHANNEL(pickupgroup) allow reading and setting the pickupgroup of channel.
318 * Mark VALID_EXTEN() deprecated in favor of DIALPLAN_EXISTS()
319 * Added extensions to chan_ooh323 in function CHANNEL()
321 libpri channel driver (chan_dahdi) DAHDI changes
322 --------------------------
323 * Added moh_signaling option to specify what to do when the channel's bridged
324 peer puts the ISDN channel on hold.
325 * Added display_send and display_receive options to control how the display ie
326 is handled. To send display text from the dialplan use the SendText()
327 application when the option is enabled.
328 * Added mcid_send option to allow sending a MCID request on a span.
331 --------------------------
332 * Added setvar option to calendar.conf to allow setting channel variables on
333 notification channels.
334 * Added "calendar show types" CLI command to list registered calendar
338 --------------------------
339 * Added two new options, r and t with file name arguments to record
340 single direction (unmixed) audio recording separate from the bidirectional
341 (mixed) recording. The mixed file name argument is optional now as long
342 as at least one recording option is used.
345 --------------------------
346 * Added a new option, l, which will disable local call optimization for
347 channels involved with the FollowMe thread. Use this option to improve
348 compatability for a FollowMe call with certain dialplan apps, options, and
352 --------------------------
353 * Added option "k" that will automatically close the conference when there's
354 only one person left when a user exits the conference.
357 --------------------------
358 * cel_pgsql now supports the 'extra' column for data added using the
359 CELGenUserEvent() application.
362 --------------------------
363 * Support for defining hints has been added to pbx_lua. See the 'hints' table
364 in the sample extensions.lua file for syntax details.
365 * Applications that perform jumps in the dialplan such as Goto will now
366 execute properly. When pbx_lua detects that the context, extension, or
367 priority we are executing on has changed it will immediately return control
368 to the asterisk PBX engine. Currently the engine cannot detect a Goto to
369 the priority after the currently executing priority.
370 * An autoservice is now started by default for pbx_lua channels. It can be
371 stopped and restarted using the autoservice_stop() and autoservice_start()
375 --------------------------
376 * The ReceiveFAXStatus and SendFAXStatus manager events have been consolidated
377 into a FAXStatus event with an 'Operation' header that will be either
378 'send', 'receive', and 'gateway'.
379 * T.38 gateway functionality has been added to res_fax (and res_fax_spandsp).
380 Set FAXOPT(gateway)=yes to enable this functionality on a channel. This
381 feature will handle converting a fax call between an audio T.30 fax terminal
382 and an IFP T.38 fax terminal.
386 * Add T38 support for REJECTED state where T.38 Negotiation is explicitly rejected.
387 * Add option encryption_taglen to set auth taglen only 32 and 80 are supported currently.
388 * SIP now generates security events using the Security Events Framework for REGISTER and INVITE.
392 * Added general option negative_penalty_invalid default off. when set
393 members are seen as invalid/logged out when there penalty is negative.
394 for realtime members when set remove from queue will set penalty to -1.
395 * Added queue option autopausedelay when autopause is enabled it will be
396 delayed for this number of seconds since last successful call if there
397 was no prior call the agent will be autopaused immediately.
398 * Added member option ignorebusy this when set and ringinuse is not
399 will allow per member control of multiple calls as ringinuse does for
401 * Added global option check_state_unknown to enforce checking of device state
402 when the device state is unknown app_queue will see unknown as available.
406 * Added 'v' option to MeetMe to play voicemail greetings when a user joins/leaves
408 * Added 'k' option to MeetMe to automatically kill the conference when there's only
409 one participant left (much like a normal call bridge)
410 * Added extra argument to Originate to set timeout.
414 * The internal Asterisk database has been switched from Berkeley DB 1.86 to
415 SQLite 3. An existing Berkeley astdb file can be converted with the astdb2sqlite3
416 utility in the UTILS section of menuselect. If an existing astdb is found and no
417 astdb.sqlite3 exists, astdb2sqlite3 will be compiled automatically. Asterisk will
418 convert an existing astdb to the SQLite3 version automatically at runtime.
422 * Modules marked as deprecated are no longer marked as building by default. Enabling
423 these modules is still available via menuselect.
427 * authdebug is now disabled by default. To enable this functionaility again
428 set authdebug = yes in iax.conf.
432 * The rtp.conf setting "strictrtp" is now enabled by default. In previous
433 releases it was disabled.
437 * The PBX core previously made a call with a non-existing extension test for
438 extension s@default and jump there if the extension existed.
439 This was a bad default behaviour and violated the principle of least surprise.
440 It has therefore been changed in this release. It may affect some
441 applications and configurations that rely on this behaviour. Most channel
442 drivers have avoided this for many releases by testing whether the extension
443 called exists before starting the PBX and generating a local error.
444 This behaviour still exists and works as before.
446 Extension "s" is used when no extension is given in a channel driver,
447 like immediate answer in DAHDI or calling to a domain with no user part
450 ------------------------------------------------------------------------------
451 --- Functionality changes from Asterisk 1.6.2 to Asterisk 1.8 ----------------
452 ------------------------------------------------------------------------------
456 * Due to potential username discovery vulnerabilities, the 'nat' setting in sip.conf
457 now defaults to force_rport. It is very important that phones requiring nat=no be
458 specifically set as such instead of relying on the default setting. If at all
459 possible, all devices should have nat settings configured in the general section as
460 opposed to configuring nat per-device.
461 * Added preferred_codec_only option in sip.conf. This feature limits the joint
462 codecs sent in response to an INVITE to the single most preferred codec.
463 * Added SIP_CODEC_OUTBOUND dialplan variable which can be used to set the codec
464 to be used for the outgoing call. It must be one of the codecs configured
466 * Added tlsprivatekey option to sip.conf. This allows a separate .pem file
467 to be used for holding a private key. If tlsprivatekey is not specified,
468 tlscertfile is searched for both public and private key.
469 * Added tlsclientmethod option to sip.conf. This allows the protocol for
470 outbound client connections to be specified.
471 * The sendrpid parameter has been expanded to include the options
472 'rpid' and 'pai'. Setting sendrpid to 'rpid' will cause Remote-Party-ID
473 header to be sent (equivalent to setting sendrpid=yes) and setting
474 sendrpid to 'pai' will cause P-Asserted-Identity header to be sent.
475 * The 'ignoresdpversion' behavior has been made automatic when the SDP received
476 is in response to a T.38 re-INVITE that Asterisk initiated. In this situation,
477 since the call will fail if Asterisk does not process the incoming SDP, Asterisk
478 will accept the SDP even if the SDP version number is not properly incremented,
479 but will generate a warning in the log indicating that the SIP peer that sent
480 the SDP should have the 'ignoresdpversion' option set.
481 * The 'nat' option has now been been changed to have yes, no, force_rport, and
482 comedia as valid values. Setting it to yes forces RFC 3581 behavior and enables
483 symmetric RTP support. Setting it to no only enables RFC 3581 behavior if the
484 remote side requests it and disables symmetric RTP support. Setting it to
485 force_rport forces RFC 3581 behavior and disables symmetric RTP support.
486 Setting it to comedia enables RFC 3581 behavior if the remote side requests it
487 and enables symmetric RTP support.
488 * Slave SIP channels now set HASH(SIP_CAUSE,<slave-channel-name>) on each
489 response. This permits the master channel to know how each channel dialled
490 in a multi-channel setup resolved in an individual way. This carries a
491 performance penalty and can be disabled in sip.conf using the
492 'storesipcause' option.
493 * Added 'externtcpport' and 'externtlsport' options to allow custom port
494 configuration for the externip and externhost options when tcp or tls is used.
495 * Added support for message body (stored in content variable) to SIP NOTIFY message
496 accessible via AMI and CLI.
497 * Added 'media_address' configuration option which can be used to explicitly specify
498 the IP address to use in the SDP for media (audio, video, and text) streams.
499 * Added 'unsolicited_mailbox' configuration option which specifies the virtual mailbox
500 that the new/old count should be stored on if an unsolicited MWI NOTIFY message is
502 * Added 'use_q850_reason' configuration option for generating and parsing
503 if available Reason: Q.850;cause=<cause code> header. It is implemented
504 in some gateways for better passing PRI/SS7 cause codes via SIP.
505 * When dialing SIP peers, a new component may be added to the end of the dialstring
506 to indicate that a specific remote IP address or host should be used when dialing
507 the particular peer. The dialstring format is SIP/peer/exten/host_or_IP.
508 * SRTP SDES support for encrypting calls to/from Asterisk over SIP. The
509 ability to selectively force bridged channels to also be encrypted is also
510 implemented. Branching in the dialplan can be done based on whether or not
511 a channel has secure media and/or signaling.
512 * Added directmediapermit/directmediadeny to limit which peers can send direct media
514 * Added the 'snom_aoc_enabled' option to turn on support for sending Advice of
515 Charge messages to snom phones.
516 * Added support for G.719 media streams.
517 * Added support for 16khz signed linear media streams.
518 * SIP is now able to bind to and communicate with IPv6 addresses. In addition,
519 RTP has been outfitted with the same abilities.
520 * Added support for setting the Max-Forwards: header in SIP requests. Setting is
521 available in device configurations as well as in the dial plan.
522 * Addition of the 'subscribe_network_change' option for turning on and off
523 res_stun_monitor module support in chan_sip.
524 * Addition of the 'auth_options_requests' option for turning on and off
525 authentication for OPTIONS requests in chan_sip.
529 * Add #tryinclude statement for config files. This provides the same
530 functionality as the #include statement however an asterisk module will
531 still load if the filename does not exist. Using the #include statement
532 Asterisk will not allow the module to load.
536 * Added rtsavesysname option into iax.conf to allow the systname to be saved
538 * Added the ability for chan_iax2 to inform the dialplan whether or not
539 encryption is being used. This interoperates with the SIP SRTP implementation
540 so that a secure SIP call can be bridged to a secure IAX call when the
541 dialplan requires bridged channels to be "secure".
542 * Addition of the 'subscribe_network_change' option for turning on and off
543 res_stun_monitor module support in chan_iax.
548 * Added ability to preset channel variables on indicated lines with the setvar
549 configuration option. Also, clearvars=all resets the list of variables back
551 * PacketCable NCS 1.0 support has been added for Docsis/Eurodocsis Networks.
552 See configs/res_pktccops.conf for more information.
554 XMPP Google Talk/Jingle changes
555 -------------------------------
556 * Added the externip option to gtalk.conf.
557 * Added the stunaddr option to gtalk.conf which allows for the automatic
558 retrieval of the external ip from a stun server.
562 * Added 'p' option to PickupChan() to allow for picking up channel by the first
563 match to a partial channel name.
564 * Added .m3u support for Mp3Player application.
565 * Added progress option to the app_dial D() option. When progress DTMF is
566 present, those values are sent immediately upon receiving a PROGRESS message
567 regardless if the call has been answered or not.
568 * Added functionality to the app_dial F() option to continue with execution
569 at the current location when no parameters are provided.
570 * Added the 'a' option to app_dial to answer the calling channel before any
571 announcements or macros are executed.
572 * Modified app_dial to set answertime when the called channel answers even if
573 the called channel hangs up during playback of an announcement.
574 * Modified app_dial 'r' option to support an additional parameter to play an
575 indication tone from indications.conf
576 * Added c() option to app_chanspy. This option allows custom DTMF to be set
577 to cycle through the next available channel. By default this is still '*'.
578 * Added x() option to app_chanspy. This option allows DTMF to be set to
579 exit the application.
580 * The Voicemail application has been improved to automatically ignore messages
581 that only contain silence.
582 * If you set maxmsg to 0 in voicemail.conf, Voicemail will consider the
583 associated mailbox(es) to be greetings-only.
584 * The ChanSpy application now has the 'S' option, which makes the application
585 automatically exit once it hits a point where no more channels are available
587 * The ChanSpy application also now has the 'E' option, which spies on a single
588 channel and exits when that channel hangs up.
589 * The MeetMe application now turns on the DENOISE() function by default, for
590 each participant. In our tests, this has significantly decreased background
591 noise (especially noisy data centers).
592 * Voicemail now permits storage of secrets in a separate file, located in the
593 spool directory of each individual user. The control for this is located in
594 the "passwordlocation" option in voicemail.conf. Please see the sample
595 configuration for more information.
596 * The ChanIsAvail application now exposes the returned cause code using a separate
597 variable, AVAILCAUSECODE, instead of overwriting the device state in AVAILSTATUS.
598 * Added 'd' option to app_followme. This option disables the "Please hold"
600 * Added 'y' option to app_record. This option enables a mode where any DTMF digit
601 received will terminate recording.
602 * Voicemail now supports per mailbox settings for folders when using IMAP storage.
603 Previously the folder could only be set per context, but has now been extended
604 using the imapfolder option.
605 * Voicemail now supports per mailbox settings for nextaftercmd and minsecs.
606 * Voicemail now allows the pager date format to be specified separately from the
608 * New applications JabberJoin, JabberLeave, and JabberSendGroup have been added
609 to allow joining, leaving, and sending text to group chats.
610 * MeetMe has a new option 'G' to play an announcement before joining a conference.
611 * Page has a new option 'A(x)' which will playback an announcement simultaneously
612 to all paged phones (and optionally excluding the caller's one using the new
613 option 'n') before the call is bridged.
614 * The 'f' option to Dial has been augmented to take an optional argument. If no
615 argument is provided, the 'f' option works as it always has. If an argument is
616 provided, then the connected party information of all outgoing channels created
617 during the Dial will be set to the argument passed to the 'f' option.
618 * Dial now inherits the GOSUB_RETVAL from the peer, when the U() option runs a
620 * The OSP lookup application adds in/outbound network ID, optional security,
621 number portability, QoS reporting, destination IP port, custom info and service
623 * Added new application VMSayName that will play the recorded name of the voicemail
624 user if it exists, otherwise will play the mailbox number.
625 * Added custom device states to ConfBridge bridges. Use 'confbridge:<name>' to
626 retrieve state for a particular bridge, where <name> is the conference name
627 * app_directory now allows exiting at any time using the operator or pound key.
628 * Voicemail now supports setting a locale per-mailbox.
629 * Two new applications are provided for declining counting phrases in multiple
630 languages. See the application notes for SayCountedNoun and SayCountedAdj for
632 * Voicemail now runs the externnotify script when pollmailboxes is activated and
634 * Voicemail now includes rdnis within msgXXXX.txt file.
635 * Added 'D' command to ExternalIVR full details in doc/externalivr.txt
636 * ParkedCall and Park can now specify the parking lot to use.
640 * SRVQUERY and SRVRESULT functions added. This can be used to query and iterate
641 over SRV records associated with a specific service. From the CLI, type
642 'core show function SRVQUERY' and 'core show function SRVRESULT' for more
643 details on how these may be used.
644 * PITCH_SHIFT dialplan function added. This function can be used to modify the
645 pitch of a channel's tx and rx audio streams.
646 * Added new dialplan functions CONNECTEDLINE and REDIRECTING which permits
647 setting various connected line and redirecting party information.
648 * CALLERID and CONNECTEDLINE dialplan functions have been extended to
649 support ISDN subaddressing.
650 * The CHANNEL() function now supports the "name" and "checkhangup" options.
651 * For DAHDI channels, the CHANNEL() dialplan function now allows
652 the dialplan to request changes in the configuration of the active
653 echo canceller on the channel (if any), for the current call only.
656 exten => s,n,Set(CHANNEL(echocan_mode)=off)
658 The possible values are:
660 on - normal mode (the echo canceller is actually reinitialized)
662 fax - FAX/data mode (NLP disabled if possible, otherwise completely
664 voice - voice mode (returns from FAX mode, reverting the changes that
665 were made when FAX mode was requested)
666 * Added new dialplan function MASTER_CHANNEL(), which permits retrieving
667 and setting variables on the channel which created the current channel.
668 Administrators should take care to avoid naming conflicts, when multiple
669 channels are dialled at once, especially when used with the Local channel
670 construct (which all could set variables on the master channel). Usage
671 of the HASH() dialplan function, with the key set to the name of the slave
672 channel, is one approach that will avoid conflicts.
673 * Added new dialplan function MUTEAUDIO() for muting inbound and/or outbound
675 * func_odbc now allows multiple row results to be retrieved without using
676 mode=multirow. If rowlimit is set, then additional rows may be retrieved
677 from the same query by using the name of the function which retrieved the
678 first row as an argument to ODBC_FETCH().
679 * Added JABBER_RECEIVE, which permits receiving XMPP messages from the
680 dialplan. This function returns the content of the received message.
681 * Added REPLACE, which searches a given variable name for a set of characters,
682 then either replaces them with a single character or deletes them.
683 * Added PASSTHRU, which literally passes the same argument back as its return
684 value. The intent is to be able to use a literal string argument to
685 functions that currently require a variable name as an argument.
686 * HASH-associated variables now can be inherited across channel creation, by
687 prefixing the name of the hash at assignment with the appropriate number of
688 underscores, just like variables.
689 * GROUP_MATCH_COUNT has been improved to allow regex matching on category
690 * CHANNEL(secure_bridge_signaling) and CHANNEL(secure_bridge_media) to set/get
691 whether or not channels that are bridged to the current channel will be
692 required to have secure signaling and/or media.
693 * CHANNEL(secure_signaling) and CHANNEL(secure_media) to get whether or not
694 the current channel has secure signaling and/or media.
695 * For DAHDI/ISDN channels, the CHANNEL() dialplan function now supports the
696 "no_media_path" option.
697 Returns "0" if there is a B channel associated with the call.
698 Returns "1" if no B channel is associated with the call. The call is either
699 on hold or is a call waiting call.
700 * Added option to dialplan function CDR(), the 'f' option
701 allows for high resolution times for billsec and duration fields.
702 * FILE() now supports line-mode and writing.
703 * Added FIELDNUM(), which returns the 1-based offset of a field in a list.
704 * FRAME_TRACE(), for tracking internal ast_frames on a channel.
708 * Added DYNAMIC_FEATURENAME which holds the last triggered dynamic feature.
709 * Added DYNAMIC_PEERNAME which holds the unique channel name on the other side
710 and is set when a dynamic feature is triggered.
711 * Added PARKINGLOT which can be used with parkeddynamic feature.conf option
712 to dynamically create a new parking lot matching the value this varible is
714 * Added PARKINGDYNAMIC which represents the template parkinglot defined in
715 features.conf that should be the base for dynamic parkinglots.
716 * Added PARKINGDYNCONTEXT which tells what context a newly created dynamic
717 parkinglot should have.
718 * Added PARKINGDYNEXTEN which tells what parking exten a newly created dynamic
719 parkinglot should have.
720 * Added PARKINGDYNPOS which holds what parking positions a dynamic parkinglot
725 * Added "ready" option to QUEUE_MEMBER counting to count free agents whose wrap-up
727 * Added 'R' option to app_queue. This option stops moh and indicates ringing
728 to the caller when an Agent's phone is ringing. This can be used to indicate
729 to the caller that their call is about to be picked up, which is nice when
730 one has been on hold for an extened period of time.
731 * A new config option, penaltymemberslimit, has been added to queues.conf.
732 When set this option will disregard penalty settings when a queue has too
734 * A new option, 'I' has been added to both app_queue and app_dial.
735 By setting this option, Asterisk will not update the caller with
736 connected line changes or redirecting party changes when they occur.
737 * A 'relative-periodic-announce' option has been added to queues.conf. When
738 enabled, this option will cause periodic announce times to be calculated
739 from the end of announcements rather than from the beginning.
740 * The autopause option in queues.conf can be passed a new value, "all." The
741 result is that if a member becomes auto-paused, he will be paused in all
742 queues for which he is a member, not just the queue that failed to reach
744 * Added dialplan function QUEUE_EXISTS to check if a queue exists
745 * The queue logger now allows events to optionally propagate to a file,
746 even when realtime logging is turned on. Additionally, realtime logging
747 supports sending the event arguments to 5 individual fields, although it
748 will fallback to the previous data definition, if the new table layout is
751 mISDN channel driver (chan_misdn) changes
752 ----------------------------------------
753 * Added display_connected parameter to misdn.conf to put a display string
754 in the CONNECT message containing the connected name and/or number if
755 the presentation setting permits it.
756 * Added display_setup parameter to misdn.conf to put a display string
757 in the SETUP message containing the caller name and/or number if the
758 presentation setting permits it.
759 * Made misdn.conf parameters localdialplan and cpndialplan take a -1 to
760 indicate the dialplan settings are to be obtained from the asterisk
762 * Made misdn.conf parameter callerid accept the "name" <number> format
763 used by the rest of the system.
764 * Made use the nationalprefix and internationalprefix misdn.conf
765 parameters to prefix any received number from the ISDN link if that
766 number has the corresponding Type-Of-Number. NOTE: This includes
767 comparing the incoming call's dialed number against the MSN list.
768 * Added the following new parameters: unknownprefix, netspecificprefix,
769 subscriberprefix, and abbreviatedprefix in misdn.conf to prefix any
770 received number from the ISDN link if that number has the corresponding
772 * Added new dialplan application misdn_command which permits controlling
773 the CCBS/CCNR functionality.
774 * Added new dialplan function mISDN_CC which permits retrieval of various
775 values from an active call completion record.
776 * For PTP, you should manually send the COLR of the redirected-to party
777 for an incomming redirected call if the incoming call could experience
778 further redirects. Just set the REDIRECTING(to-num,i) = ${EXTEN} and
779 set the REDIRECTING(to-pres) to the COLR. A call has been redirected
780 if the REDIRECTING(from-num) is not empty.
781 * For outgoing PTP redirected calls, you now need to use the inhibit(i)
782 option on all of the REDIRECTING statements before dialing the
783 redirected-to party. You still have to set the REDIRECTING(to-xxx,i)
784 and the REDIRECTING(from-xxx,i) values. The PTP call will update the
785 redirecting-to presentation (COLR) when it becomes available.
786 * Added outgoing_colp parameter to misdn.conf to filter outgoing COLP
789 thirdparty mISDN enhancements
790 -----------------------------
791 mISDN has been modified by Digium, Inc. to greatly expand facility message
793 * Enhanced COLP support for call diversion and transfer.
796 The latest modified mISDN v1.1.x based version is available at:
797 http://svn.digium.com/svn/thirdparty/mISDN/trunk
798 http://svn.digium.com/svn/thirdparty/mISDNuser/trunk
800 Tagged versions of the modified mISDN code are available under:
801 http://svn.digium.com/svn/thirdparty/mISDN/tags
802 http://svn.digium.com/svn/thirdparty/mISDNuser/tags
804 libpri channel driver (chan_dahdi) DAHDI changes
805 -------------------------------------------
806 * The channel variable PRIREDIRECTREASON is now just a status variable
807 and it is also deprecated. Use the REDIRECTING(reason) dialplan function
808 to read and alter the reason.
809 * For Q.SIG and ETSI PRI/BRI-PTP, you should manually send the COLR of the
810 redirected-to party for an incomming redirected call if the incoming call
811 could experience further redirects. Just set the
812 REDIRECTING(to-num,i) = CALLERID(dnid) and set the REDIRECTING(to-pres)
813 to the COLR. A call has been redirected if the REDIRECTING(count) is not
815 * For outgoing Q.SIG and ETSI PRI/BRI-PTP redirected calls, you need to
816 use the inhibit(i) option on all of the REDIRECTING statements before
817 dialing the redirected-to party. You still have to set the
818 REDIRECTING(to-xxx,i) and the REDIRECTING(from-xxx,i) values. The call
819 will update the redirecting-to presentation (COLR) when it becomes available.
820 * Added the ability to ignore calls that are not in a Multiple Subscriber
821 Number (MSN) list for PTMP CPE interfaces.
822 * Added dynamic range compression support for dahdi channels. It is
823 configured via the rxdrc and txdrc parameters in chan_dahdi.conf.
824 * Added support for ISDN calling and called subaddress with partial support
825 for connected line subaddress.
826 * Added support for BRI PTMP NT mode. (Requires latest LibPRI.)
827 * Added handling of received HOLD/RETRIEVE messages and the optional ability
828 to transfer a held call on disconnect similar to an analog phone.
829 * Added CallRerouting/CallDeflection support for Q.SIG, ETSI PTP, ETSI PTMP.
830 Will reroute/deflect an outgoing call when receive the message.
831 Can use the DAHDISendCallreroutingFacility to send the message for the
833 * Added standard location to add options to chan_dahdi dialing:
834 Dial(DAHDI/g1[/extension[/options]])
837 R Reverse charging indication
838 * Added Reverse Charging Indication (Collect calls) send/receive option.
839 Send reverse charging in SETUP message with the chan_dahdi R dialing option.
840 Dial(DAHDI/g1/extension/R)
841 Access received reverse charge in SETUP message by: ${CHANNEL(reversecharge)}
842 (requires latest LibPRI)
843 * Added ability to send/receive keypad digits in the SETUP message.
844 Send keypad digits in SETUP message with the chan_dahdi K(<keypad_digits>)
845 dialing option. Dial(DAHDI/g1/[extension]/K(<keypad_digits>))
846 Access any received keypad digits in SETUP message by: ${CHANNEL(keypad_digits)}
847 (requires latest LibPRI)
848 * Added ability to send and receive ETSI Explicit Call Transfer (ECT) messages
849 to eliminate tromboned calls. A tromboned call goes out an interface and comes
850 back into the same interface. Tromboned calls happen because of call routing,
851 call deflection, call forwarding, and call transfer.
852 * Added the ability to send and receive ETSI Advice-Of-Charge messages.
853 * Added the ability to support call waiting calls. (The SETUP has no B channel
855 * Added Malicious Call ID (MCID) event to the AMI call event class.
856 * Added Message Waiting Indication (MWI) support for ISDN PTMP endpoints (phones).
858 Asterisk Manager Interface
859 --------------------------
860 * The Hangup action now accepts a Cause header which may be used to
861 set the channel's hangup cause.
862 * sslprivatekey option added to manager.conf and http.conf. Adds the ability
863 to specify a separate .pem file to hold a private key. By default sslcert
864 is used to hold both the public and private key.
865 * Options in manager.conf and http.conf with the 'ssl' prefix have been replaced
866 for options containing the 'tls' prefix. For example, 'sslenable' is now
867 'tlsenable'. This has been done in effort to keep ssl and tls options consistent
868 across all .conf files. All affected sample.conf files have been modified to
869 reflect this change. Previous options such as 'sslenable' still work,
870 but options with the 'tls' prefix are preferred.
871 * Added a MuteAudio AMI action for muting inbound and/or outbound audio
872 in a channel. (res_mutestream.so)
873 * The configuration file manager.conf now supports a channelvars option, which
874 specifies a list of channel variables to include in each channel-oriented
876 * The redirect command now has new parameters ExtraContext, ExtraExtension,
877 and ExtraPriority to allow redirecting the second channel to a different
878 location than the first.
879 * Added new event "JabberStatus" in the Jabber module to monitor buddies
881 * Added a "MixMonitorMute" AMI action for muting inbound and/or outbound audio
882 in a MixMonitor recording.
883 * The 'iax2 show peers' output is now similar to the expected output of
885 * Added Advice-Of-Charge events (AOC-S, AOC-D, and AOC-E) in the new
887 * Added Advice-Of-Charge manager action, AOCMessage, for generating AOC-D and
888 AOC-E messages on a channel.
889 * A DBGetComplete event now follows a DBGetResponse, to make the DBGet action
890 conform more closely to similar events.
891 * Added a new eventfilter option per user to allow whitelisting and blacklisting
893 * Added optional parkinglot variable for park command.
894 * Added ConnectedLineNum and ConnectedLineName headers to AMI events/responses
895 if CallerIDNum and CallerIDName headers are also present.
897 Channel Event Logging
898 ---------------------
899 * A new interface, CEL, is introduced here. CEL logs single events, much like
900 the AMI, but it differs from the AMI in that it logs to db backends much
901 like CDR does; is based on the event subsystem introduced by Russell, and
902 can share in all its benefits; allows multiple backends to operate like CDR;
903 is specialized to event data that would be of concern to billing sytems,
904 like CDR. Backends for logging and accounting calls have been produced,
905 but a new CDR backend is still in development.
909 * 'linkedid' and 'peeraccount' are new CDR fields available to CDR aficionados.
910 linkedid is based on uniqueID, but spreads to other channels as transfers, dials,
911 etc are performed. Thus the pieces of CDR can be grouped into multilegged sets.
912 * Multiple files and formats can now be specified in cdr_custom.conf.
913 * cdr_syslog has been added which allows CDRs to be written directly to syslog.
914 See configs/cdr_syslog.conf.sample for more information.
915 * A 'sequence' field has been added to CDRs which can be combined with
916 linkedid or uniqueid to uniquely identify a CDR.
917 * Handling of billsec and duration field has changed. If your table definition
918 specifies those fields as float,double or similar they will now be logged with
919 microsecond accuracy instead of a whole integer.
921 Calendaring for Asterisk
922 ------------------------
923 * A new set of modules were added supporing calendar integration with Asterisk.
924 Dialplan functions for reading from and writing to calendars are included,
925 as well as the ability to execute dialplan logic upon calendar event notifications.
926 iCalendar, CalDAV, and Exchange Server calendars (via res_calendar_exchange for
927 Exchange Server 2003 with no write or attendee support, and res_calendar_ews for
928 Exchange Server 2007+ with full write and attendee support) are supported (Exchange
929 2003 support does not support forms-based authentication).
931 Call Completion Supplementary Services for Asterisk
932 ---------------------------------------------------
933 * Call completion support has been added for SIP, DAHDI/ISDN, and DAHDI/analog.
934 DAHDI/ISDN supports call completion for the following switch types:
935 EuroIsdn(ETSI) for PTP and PTMP modes, and Qsig.
936 See doc/CCSS_architecture.pdf and doc/tex/ccss.tex(asterisk.pdf) for details.
938 Multicast RTP Support
939 ---------------------
940 * A new RTP engine and channel driver have been added which supports Multicast RTP.
941 The channel driver can be used with the Page application to perform multicast RTP
942 paging. The dial string format is: MulticastRTP/<type>/<destination>/<control address>
943 Type can be either basic or linksys.
944 Destination is the IP address and port for the RTP packets.
945 Control address is specific to the linksys type and is used for sending the control
946 packets unique to them.
948 Security Events Framework
949 -------------------------
950 * Asterisk has a new C API for reporting security events. The module res_security_log
951 sends these events to the "security" logger level. Currently, AMI is the only
952 Asterisk component that reports security events. However, SIP support will be
953 coming soon. For more information on the security events framework, see the
954 "Security Events" chapter of the included documentation - doc/tex/asterisk.pdf.
958 * A technology independent fax frontend (res_fax) has been added to Asterisk.
959 * A spandsp based fax backend (res_fax_spandsp) has been added.
960 * The app_fax module has been deprecated in favor of the res_fax module and
961 the new res_fax_spandsp backend.
962 * The SendFAX and ReceiveFAX applications now send their log messages to a
963 'fax' logger level, instead of to the generic logger levels. To see these
964 messages, the system's logger.conf file will need to direct the 'fax' logger
965 level to one or more destinations; the logger.conf.sample file includes an
966 example of how to do this. Note that if the 'fax' logger level is *not*
967 directed to at least one destination, log messages generated by these
968 applications will be lost, and that if the 'fax' logger level is directed to
969 the console, the 'core set verbose' and 'core set debug' CLI commands will
970 have no effect on whether the messages appear on the console or not.
974 * The transmit_silence_during_record option in asterisk.conf.sample has been removed.
975 Now, in order to enable transmitting silence during record the transmit_silence
976 option should be used. transmit_silence_during_record remains a valid option, but
977 defaults to the behavior of the transmit_silence option.
978 * Addition of the Unit Test Framework API for managing registration and execution
979 of unit tests with the purpose of verifying the operation of C functions.
980 * SendText is now implemented in chan_gtalk and chan_jingle. It will simply send
981 XMPP text messages to the remote JID.
982 * Modules.conf has a new option - "require" - that marks a module as critical for
983 the execution of Asterisk.
984 If one of the required modules fail to load, Asterisk will exit with a return
986 * An 'X' option has been added to the asterisk application which enables #exec support.
987 This allows #exec to be used in asterisk.conf.
988 * jabber.conf supports a new option auth_policy that toggles auto user registration.
989 * A new lockconfdir option has been added to asterisk.conf to protect the
990 configuration directory (/etc/asterisk by default) during reloads.
991 * The parkeddynamic option has been added to features.conf to enable the creation
992 of dynamic parkinglots.
993 * chan_dahdi now supports reporting alarms over AMI either by channel or span via
994 the reportalarms config option.
995 * chan_dahdi supports dialing configuring and dialing by device file name.
996 DAHDI/span-name!local!1 will use /dev/dahdi/span-name/local/1 . Likewise
997 it may appear in chan_dahdi.conf as 'channel => span-name!local!1'.
998 * A new options for chan_dahdi.conf: 'ignore_failed_channels'. Boolean.
999 False by default. If set, chan_dahdi will ignore failed 'channel' entries.
1000 Handy for the above name-based syntax as it does not depend on
1001 initialization order.
1002 * The Realtime dialplan switch now caches entries for 1 second. This provides a
1003 significant increase in performance (about 3X) for installations using this switchtype.
1004 * Distributed devicestate now supports the use of the XMPP protocol, in addition to
1005 AIS. For more information, please see doc/distributed_devstate-XMPP.txt
1006 * The addition of G.719 pass-through support.
1007 * Added support for 16khz Speex audio. This can be enabled by using 'allow=speex16'
1008 during device configuration.
1009 * The UNISTIM channel driver (chan_unistim) has been updated to support devices that
1010 have less than 3 lines on the LCD.
1011 * Realtime now supports database failover. See the sample extconfig.conf for details.
1012 * The addition of improved translation path building for wideband codecs. Sample
1013 rate changes during translation are now avoided unless absolutely necessary.
1014 * The addition of the res_stun_monitor module for monitoring and reacting to network
1015 changes while behind a NAT.
1019 * The 'core set debug' and 'core set verbose' commands, in previous versions, could
1020 optionally accept a filename, to apply the setting only to the code generated from
1021 that source file when Asterisk was built. However, there are some modules in Asterisk
1022 that are composed of multiple source files, so this did not result in the behavior
1023 that users expected. In this version, 'core set debug' and 'core set verbose'
1024 can optionally accept *module* names instead (with or without the .so extension),
1025 which applies the setting to the entire module specified, regardless of which source
1026 files it was built from.
1027 * New 'manager show settings' command showing the current settings loaded from
1029 * Added 'all' keyword to the CLI command "channel request hangup" so that you can send
1030 the channel hangup request to all channels.
1031 * Added a "core reload" CLI command that executes a global reload of Asterisk.
1033 ------------------------------------------------------------------------------
1034 --- Functionality changes from Asterisk 1.6.1 to Asterisk 1.6.2 -------------
1035 ------------------------------------------------------------------------------
1039 * Added support for SUBSCRIBE/NOTIFY with dialog-info based call pickups.
1040 Snom phones use this for call pickup of extensions that the phone is
1042 * Added support for setting the domain in the URI for caller of an
1043 outbound call by using the SIPFROMDOMAIN channel variable.
1044 * Added a new configuration option "remotesecret" for authentication to
1045 remote services. For backwards compatibility, "secret" still has the
1046 same function as before, but now you can configure both a remote secret and a
1047 local secret for mutual authentication.
1048 * If the channel variable ATTENDED_TRANSFER_COMPLETE_SOUND is set,
1049 the sound will be played to the target of an attended transfer
1050 * Added two new configuration options, "qualifygap" and "qualifypeers", which allow
1051 finer control over how many peers Asterisk will qualify and the gap between them
1052 when all peers need to be qualified at the same time.
1053 * Added a new 'ignoresdpversion' option to sip.conf. When this is enabled
1054 (either globally or for a specific peer), chan_sip will treat any SDP data
1055 it receives as new data and update the media stream accordingly. By
1056 default, Asterisk will only modify the media stream if the SDP session
1057 version received is different from the current SDP session version. This
1058 option is required to interoperate with devices that have non-standard SDP
1059 session version implementations (observed with Microsoft OCS). This option
1060 is disabled by default.
1061 * The parsing of register => lines in sip.conf has been modified to allow a port
1062 to be present in the "user" portion. Please see the sip.conf.sample file for more
1064 * Added support for subscribing to MWI on a remote server and making the status available
1065 as a mailbox. Please see the sip.conf.sample file for more information.
1066 * Added a function to remove SIP headers added in the dialplan before the
1067 first INVITE is generated - SIPRemoveHeader()
1068 * Channel variables set with setvar= in a device configuration is now
1069 set both for inbound and outbound calls.
1070 * Added support for ITU G.722.1 and G.722.1C (Siren7 and Siren14) media streams.
1074 * Added immediate option to iax.conf
1075 * Added forceencryption option to iax.conf
1076 * Added Encryption and Trunk status to manager command "iaxpeers"
1080 * The configuration file now holds separate sections for devices and lines.
1081 Please have a look at configs/skinny.conf.sample and change your skinny.conf
1086 * chan_dahdi now supports MFC/R2 signaling when Asterisk is compiled with
1087 support for LibOpenR2. http://www.libopenr2.org/
1088 * The UK option waitfordialtone has been added for use with BT analog
1090 * Added a 'faxbuffers' configuration option to chan_dahdi.conf. This option
1091 is used in conjunction with the 'faxdetect' configuration option. When
1092 'faxbuffers' is used and fax tones are detected, the channel will dynamically
1093 switch to the configured faxbuffers policy. For example, to use 6 buffers
1094 and a 'full' buffer policy for a fax transmission, add:
1096 The faxbuffers configuration will be in affect until the call is torn down.
1097 * Added service message support for 4ESS/5ESS switches.
1101 * For DAHDI channels, the CHANNEL() dialplan function now
1102 supports changing the channel's buffer policy (for the current
1103 call only), using this syntax:
1105 exten => s,n,Set(CHANNEL(buffers)=6,full)
1107 This would change the channel to the 'full' buffer policy and
1108 6 (six) buffers. Possible options for this setting are the same
1109 as those in chan_dahdi.conf.
1110 * Added a new dialplan function, CURLOPT, which permits setting various
1111 options that may be useful with the CURL dialplan function, such as
1112 cookies, proxies, connection timeouts, passwords, etc.
1113 * Permit the syntax and synopsis fields of the corresponding dialplan
1114 functions to be individually set from func_odbc.conf.
1115 * Added debugging CLI functions to func_odbc, 'odbc read' and 'odbc write'.
1116 * func_odbc now may specify an insert query to execute, when the write query
1117 affects 0 rows (usually indicating that no such row exists).
1118 * Added a new dialplan function, LISTFILTER, which permits removing elements
1119 from a set list, by name. Uses the same general syntax as the existing CUT
1120 and FIELDQTY dialplan functions, which also manage lists.
1121 * Added REALTIME_FIELD and REALTIME_HASH, which should aid users in better
1122 obtaining realtime data from the dialplan.
1123 * Added LOCAL_PEEK, which allows access to variables in any stack frame within
1124 a subroutine when using the GoSub() and Return() applications.
1125 * Added AUDIOHOOK_INHERIT. For information on its use, please see the output
1126 of "core show function AUDIOHOOK_INHERIT" from the CLI
1127 * Added AES_ENCRYPT. For information on its use, please see the output
1128 of "core show function AES_ENCRYPT" from the CLI
1129 * Added AES_DECRYPT. For information on its use, please see the output
1130 of "core show function AES_DECRYPT" from the CLI
1131 * func_odbc now supports database transactions across multiple queries.
1135 * Scheduled meetme conferences may now have their end times extended by
1137 * app_authenticate now gives the ability to select a prompt other than
1139 * app_directory now pays attention to the searchcontexts setting in
1140 voicemail.conf and will look through all contexts, if no context is
1141 specified in the initial argument.
1142 * A new application, Originate, has been introduced, that allows asynchronous
1143 call origination from the dialplan.
1144 * Voicemail now permits setting the emailsubject and emailbody per mailbox,
1145 in addition to the setting in the "general" context.
1146 * Added ConfBridge dialplan application which does conference bridges without
1147 DAHDI. For information on its use, please see the output of
1148 "core show application ConfBridge" from the CLI.
1152 * The Asterisk CLI has a new command, "channel redirect", which is similar in
1153 operation to the AMI Redirect action.
1154 * extensions.conf now allows you to use keyword "same" to define an extension
1155 without actually specifying an extension. It uses exactly the same pattern
1156 as previously used on the last "exten" line. For example:
1157 exten => 123,1,NoOp(something)
1158 same => n,SomethingElse()
1159 * musiconhold.conf classes of type 'files' can now use relative directory paths,
1160 which are interpreted as relative to the astvarlibdir setting in asterisk.conf.
1161 * All deprecated CLI commands are removed from the sourcecode. They are now handled
1162 by the new clialiases module. See cli_aliases.conf.sample file.
1163 * Times within timespecs are now accurate down to the minute. This is a change
1164 from historical Asterisk, which only provided timespecs rounded to the nearest
1165 even (read: evenly divisible by 2) minute mark.
1166 * The realtime switch now supports an option flag, 'p', which disables searches for
1168 * In addition to a time range and date range, timespecs now accept a 5th optional
1169 argument, timezone. This allows you to perform time checks on alternate
1170 timezones, especially if those daylight savings time ranges vary from your
1171 machine's native timezone. See GotoIfTime, ExecIfTime, IFTIME(), and timed
1173 * The contrib/scripts/ directory now has a script called sip_nat_settings that will
1174 give you the correct output for an asterisk box behind nat. It will give you the
1175 externhost and localnet settings.
1176 * The Asterisk core now supports ITU G.722.1 and G.722.1C media streams, and
1177 can connect calls in passthrough mode, as well as record and play back files.
1178 * Successful and unsuccessful call pickup can now be alerted through sounds, by
1179 using pickupsound and pickupfailsound in features.conf.
1180 * ASTVARRUNDIR is now set to $(localstatedir)/run/asterisk by default.
1181 This means the asterisk pid file will now be in /var/run/asterisk/asterisk.pid on LINUX
1182 instead of the /var/run/asterisk.pid where it used to be. This will make
1183 installs as non-root easier to manage.
1188 * The cdr.conf file must exist and be correctly programmed in order for CDR records to
1189 be written; they will no longer be explicitly written.
1191 Asterisk Manager Interface
1192 --------------------------
1193 * When using the AMI over HTTP, you can now include a 'SuppressEvents' header (with
1194 a non-empty value) in your request. If you do this, any pending AMI events will
1195 *not* be included in the response to your request as they would normally, but
1196 will be left in the event queue for the next request you make to retrieve. For
1197 some applications, this will allow you to guarantee that you will only see
1198 events in responses to 'WaitEvent' actions, and can better know when to expect them.
1199 To know whether the Asterisk server supports this header or not, your client can
1200 inspect the first response back from the server to see if it includes this header:
1202 Pragma: SuppressEvents
1204 If this is included, the server supports event suppression.
1206 * Added 4 new Actions to list skinny device(s) and line(s)
1212 LDAP Schema File Additions
1213 --------------------------
1214 * Added AsteriskDialplan, AsteriskAccount and AsteriskMailbox objectClasses
1215 to allow standalone dialplan, account and mailbox entries (STRUCTURAL)
1217 - AstAccountLanguage, AstAccountTransport, AstAccountPromiscRedir,
1218 - AstAccountAccountCode, AstAccountSetVar, AstAccountAllowOverlap,
1219 - AstAccountVideoSupport, AstAccountIgnoreSDPVersion
1220 * Removed redundant IPaddr (there's already IPAddress)
1221 - Gives more configuration Flags for SIP-Users available (tested)
1222 - Allows to create Asterisk Attributes in defined Asterisk ObjectClasses
1223 without extensibleObject (which really should be the last resort); gives
1224 also additional possibilities for LDAP-filter
1226 ------------------------------------------------------------------------------
1227 --- Functionality changes from Asterisk 1.6.0 to Asterisk 1.6.1 -------------
1228 ------------------------------------------------------------------------------
1230 Device State Handling
1231 ---------------------
1232 * The event infrastructure in Asterisk got another big update to help support
1233 distributed events. It currently supports distributed device state and
1234 distributed Voicemail MWI (Message Waiting Indication). A new module has
1235 been merged, res_ais, which facilitates communicating events between servers.
1236 It uses the SAForum AIS (Service Availability Forum Application Interface
1237 Specification) CLM (Cluster Management) and EVT (Event) services to maintain
1238 a cluster of Asterisk servers, and to share events between them. For more
1239 information on setting this up, see doc/distributed_devstate.txt.
1243 * Added a new dialplan function, AST_CONFIG(), which allows you to access
1244 variables from an Asterisk configuration file.
1245 * The JACK_HOOK function now has a c() option to supply a custom client name.
1246 * Added two new dialplan functions from libspeex for audio gain control and
1247 denoise, AGC() and DENOISE(). Both functions can be applied to the tx and
1248 rx directions of a channel from the dialplan.
1249 * The SMDI_MSG_RETRIEVE function now has the ability to search for SMDI messages
1250 based on other parameters. The default is still to search based on the
1251 forwarding station ID. However, there are new options that allow you to search
1252 based on the message desk terminal ID, or the message desk number.
1253 * TIMEOUT() has been modified to be accurate down to the millisecond.
1254 * ENUM*() functions now include the following new options:
1255 - 'u' returns the full URI and does not strip off the URI-scheme.
1256 - 's' triggers ISN specific rewriting
1257 - 'i' looks for branches into an Infrastructure ENUM tree
1258 - 'd' for a direct DNS lookup without any flipping of digits.
1259 * TXCIDNAME() has a new zone-suffix parameter (which defaults to 'e164.arpa')
1260 * CHANNEL() now has options for the maximum, minimum, and standard or normal
1261 deviation of jitter, rtt, and loss for a call using chan_sip.
1263 DAHDI channel driver (chan_dahdi) Changes
1264 ----------------------------------------
1265 * Channels can now be configured using named sections in chan_dahdi.conf, just
1266 like other channel drivers, including the use of templates.
1267 * The default for pridialplan has changed from 'national' to 'unknown'.
1271 * It is now possible to specify a pattern match as a hint. Once a phone subscribes
1272 to something that matches the pattern a hint will be created using the contents
1273 and variables evaluated.
1274 * Dialplan matching has been extended to allow an extension to return to the
1275 PBX core to wait for more digits. This is done by using the new dialplan
1276 application called "Incomplete". This will permit a whole new level of
1277 extension control, by giving the administrator more control over early
1278 matches employing one of the short-circuit pattern match operators. Note
1279 that custom applications can trigger this same behavior by returning the
1280 special value AST_PBX_INCOMPLETE.
1284 * Directory now permits both first and last names to be matched at the same
1285 time. In addition, the number of digits to enter of the name can be set in
1286 the arguments to Directory; previously, you could enter only 3, regardless
1287 of how many names are in your company. For large companies, this should be
1289 * Voicemail now permits a mailbox setting to wrap around from first to last
1290 messages, if the "messagewrap" option is set to a true value.
1291 * Voicemail now permits an external script to be run, for password validation.
1292 The script should output "VALID" or "INVALID" on stdout, depending upon the
1293 wish to validate or invalidate the password given. Arguments are:
1294 "mailbox" "context" "oldpass" "newpass". See the sample voicemail.conf for
1296 * Dial has a new option: F(context^extension^pri), which permits a callee to
1297 continue in the dialplan, at the specified label, if the caller hangs up.
1298 * ChanSpy and ExtenSpy have a new option, 's' which suppresses speaking the
1299 technology name (e.g. SIP, IAX, etc) of the channel being spied on.
1300 * The Jack application now has a c() option to supply a custom client name.
1301 * Chanspy has a new option, 'B', which can be used to "barge" on a call. This is
1302 like the pre-existing whisper mode, except that the spy can also talk to the
1303 participant on the bridged channel as well.
1304 * Chanspy has a new option, 'n', which will allow for the spied-on party's name
1305 to be spoken instead of the channel name or number. For more information on the
1306 use of this option, issue the command "core show application ChanSpy" from the
1308 * Chanspy has a new option, 'd', which allows the spy to use DTMF to swap between
1309 spy modes. Use of this feature overrides the typical use of numeric DTMF. In other
1310 words, if using the 'd' option, it is not possible to enter a number to append to
1311 the first argument to Chanspy(). Pressing 4 will change to spy mode, pressing 5 will
1312 change to whisper mode, and pressing 6 will change to barge mode.
1313 * ExternalIVR now takes several options that affect the way it performs, as
1314 well as having several new commands. Please see doc/externalivr.txt for the
1315 complete documentation.
1316 * Added ability to communicate over a TCP socket instead of forking a child process for the
1317 ExternalIVR application.
1318 * ChanIsAvail has a new option, 'a', which will return all available channels instead
1319 of just the first one if you give the function more then one channel to check.
1320 * PrivacyManager now takes an option where you can specify a context where the
1321 given number will be matched. This way you have more control over who is allowed
1322 and it stops the people who blindly enter 10 digits.
1323 * ForkCDR has new options: 'a' updates the answer time on the new CDR; 'A' locks
1324 answer times, disposition, on orig CDR against updates; 'D' Copies the disposition
1325 from the orig CDR to the new CDR after reset; 'e' sets the 'end' time on the
1326 original CDR; 'R' prevents the new CDR from being reset; 's(var=val)' adds/changes
1327 the 'var' variable on the original CDR; 'T' forces ast_cdr_end(), ast_cdr_answer(),
1328 obey the LOCKED flag on cdr's in the chain, and also the ast_cdr_setvar() func.
1329 * The Dial() application no longer copies the language used by the caller to the callee's
1330 channel. If you desire for the caller's channel's language to be used for file playback
1331 to the callee, then the file specified may be prepended with "${CHANNEL(language)}/" .
1332 * SendImage() no longer hangs up the channel on error; instead, it sets the
1333 status variable SENDIMAGESTATUS to one of 'SUCCESS', 'FAILURE', or
1334 'UNSUPPORTED'. This change makes SendImage() more consistent with other
1336 * Park has a new option, 's', which silences the announcement of the parking space number.
1337 * A non-numeric, zero, or negative timeout specified to Dial() will now be interpreted as
1338 invalid input and will be assumed to mean that no timeout is desired.
1342 * Added DNS manager support to registrations for peers referencing peer entries.
1343 DNS manager runs in the background which allows DNS lookups to be run asynchronously
1344 as well as periodically updating the IP address. These properties allow for
1345 better performance as well as recovery in the event of an IP change.
1346 * Performance improvements via using hash tables (astobj2) and doubly-linked lists to improve
1347 load/reload of large numbers of peers/users by ~40x (for large lists of peers).
1348 These changes also provide performance improvements for call setup and tear down.
1349 * Added ability to specify registration expiry time on a per registration basis in
1351 * Added support for T140 RED - redundancy in T.140 to prevent text loss due to
1353 * Added t38pt_usertpsource option. See sip.conf.sample for details.
1354 * Added SIPnotify AMI command, for sending arbitrary SIP notify commands.
1355 * 'sip show peers' and 'sip show users' display their entries sorted in
1356 alphabetical order, as opposed to the order they were in, in the config
1358 * Videosupport now supports an additional option, "always", which always sets
1359 up video RTP ports, even on clients that don't support it. This helps with
1360 callfiles and certain transfers to ensure that if two video phones are
1361 connected, they will always share video feeds.
1365 * Existing DNS manager lookups extended to check for SRV records.
1366 * IAX2 encryption support has been improved to support periodic key rotation
1367 within a call for enhanced security. The option "keyrotate" has been
1368 provided to disable this functionality to preserve backwards compatibility
1369 with older versions of IAX2 that do not support key rotation.
1373 * New CLI command, "data get <path> [<search> [<filter>]]" which retrieves the
1374 data tree based on the given <path>.
1375 * New CLI command "data show providers" that will display all the registered
1377 * New CLI command, "config reload <file.conf>" which reloads any module that
1378 references that particular configuration file. Also added "config list"
1379 which shows which configuration files are in use.
1380 * New CLI commands, "pri show version" and "ss7 show version" that will
1381 display which version of libpri and libss7 are being used, respectively.
1382 A new API call was added so trunk will now have to be compiled against
1383 a versions of libpri and libss7 that have them or it will not know that
1384 these libraries exist.
1385 * The commands "core show globals", "core set global" and "core set chanvar" has
1386 been deprecated in favor of the more semanticly correct "dialplan show globals",
1387 "dialplan set chanvar" and "dialplan set global".
1388 * New CLI command "dialplan show chanvar" to list all variables associated
1389 with a given channel.
1393 * Addresses managed by DNS manager now can check to see if there is a DNS
1394 SRV record for a given domain and will use that hostname/port if present.
1396 AMI - The manager (TCP/TLS/HTTP)
1397 --------------------------------
1398 * The Status command now takes an optional list of variables to display
1399 along with channel status.
1400 * The QueueEntry event now also includes the channel's uniqueid
1404 * res_odbc no longer has a limit of 1023 total possible unshared connections,
1405 as some people were running into this limit. This limit has been increased
1410 * The TRANSFER queue log entry now includes the the caller's original
1411 position in the transferred-from queue.
1412 * A new configuration option, "timeoutpriority" has been added. Please see the section labeled
1413 "QUEUE TIMING OPTIONS" in configs/queues.conf.sample for a detailed explanation of the option
1414 as well as an explanation about timeout options in general
1415 * Added a new option - C - for forcing the "answered elsewhere" flag on
1416 cancellation of calls in to members of the queue. This is to avoid the
1417 call to a member of a queue having the call listed as a "missed call".
1421 * Several (ODBC, Postgres, MySQL, SQLite) realtime drivers have been given
1422 adaptive capabilities. What this means in practical terms is that if your
1423 realtime table lacks critical fields, Asterisk will now emit warnings to
1424 that effect. Also, some of the realtime drivers have the ability (if
1425 configured) to automatically add those columns to the table with the
1426 correct type and length.
1430 * The channel variable ATTENDED_TRANSFER_COMPLETE_SOUND can now be set using
1431 the 'setvar' option to cause a given audio file to be played upon completion
1432 of an attended transfer. Currently it works for DAHDI, IAX2, SIP, and
1433 Skinny channels only.
1434 * You can now compile Asterisk against the Hoard Memory Allocator, see doc/hoard.txt
1435 for more information.
1436 * Config file variables may now be appended to, by using the '+=' append
1437 operator. This is most helpful when working with long SQL queries in
1438 func_odbc.conf, as the queries no longer need to be specified on a single
1440 * CDR config file, cdr.conf, has an added option, "initiatedseconds",
1441 which will add a second to the billsec when the ending
1442 time is set, if the number in the microseconds field of the end time is
1443 greater than the number of microseconds in the answer time. This allows
1444 users to count the 'initiated' seconds in their billing records.
1446 ------------------------------------------------------------------------------
1447 --- Functionality changes from Asterisk 1.4.X to Asterisk 1.6.0 -------------
1448 ------------------------------------------------------------------------------
1450 AMI - The manager (TCP/TLS/HTTP)
1451 --------------------------------
1452 * Manager has undergone a lot of changes, all of them documented
1453 in doc/manager_1_1.txt
1454 * Manager version has changed to 1.1
1455 * Added a new action 'CoreShowChannels' to list currently defined channels
1456 and some information about them.
1457 * Added a new action 'SIPshowregistry' to list SIP registrations.
1458 * Added TLS support for the manager interface and HTTP server
1459 * Added the URI redirect option for the built-in HTTP server
1460 * The output of CallerID in Manager events is now more consistent.
1461 CallerIDNum is used for number and CallerIDName for name.
1462 * Enable https support for builtin web server.
1463 See configs/http.conf.sample for details.
1464 * Added a new action, GetConfigJSON, which can return the contents of an
1465 Asterisk configuration file in JSON format. This is intended to help
1466 improve the performance of AJAX applications using the manager interface
1468 * SIP and IAX manager events now use "ChannelType" in all cases where we
1469 indicate channel driver. Previously, we used a mixture of "Channel"
1470 and "ChannelDriver" headers.
1471 * Added a "Bridge" action which allows you to bridge any two channels that
1472 are currently active on the system.
1473 * Added a "ListAllVoicemailUsers" action that allows you to get a list of all
1474 the voicemail users setup.
1475 * Added 'DBDel' and 'DBDelTree' manager commands.
1476 * cdr_manager now reports events via the "cdr" level, separating it from
1477 the very verbose "call" level.
1478 * Manager users are now stored in memory. If you change the manager account
1479 list (delete or add accounts) you need to reload manager.
1480 * Added Masquerade manager event for when a masquerade happens between
1482 * Added "manager reload" command for the CLI
1483 * Lots of commands that only provided information are now allowed under the
1484 Reporting privilege, instead of only under Call or System.
1485 * The IAX* commands now require either System or Reporting privilege, to
1486 mirror the privileges of the SIP* commands.
1487 * Added ability to retrieve list of categories in a config file.
1488 * Added ability to retrieve the content of a particular category.
1489 * Added ability to empty a context.
1490 * Created new action to create a new file.
1491 * Updated delete action to allow deletion by line number with respect to category.
1492 * Added new action insert to add new variable to category at specified line.
1493 * Updated action newcat to allow new category to be inserted in file above another
1495 * Added new event "JitterBufStats" in the IAX2 channel
1496 * Originate now requires the Originate privilege and, if you want to call out
1497 to a subshell, it requires the System privilege, as well. This was done to
1498 enhance manager security.
1499 * Originate now accepts codec settings with "Codecs: alaw, ulaw, h264"
1500 * New command: Atxfer. See doc/manager_1_1.txt for more details or
1501 manager show command Atxfer from the CLI
1502 * New command: IAXregistry. See doc/manager_1_1.txt for more details or
1503 manager show command IAXregistry from the CLI
1507 * Added the DEVICE_STATE() dialplan function which allows retrieving any device
1508 state in the dialplan, as well as creating custom device states that are
1509 controllable from the dialplan.
1510 * Extend CALLERID() function with "pres" and "ton" parameters to
1511 fetch string representation of calling number presentation indicator
1512 and numeric representation of type of calling number value.
1513 * MailboxExists converted to dialplan function
1514 * A new option to Dial() for telling IP phones not to count the call
1515 as "missed" when dial times out and cancels.
1516 * Added LOCK(), TRYLOCK(), and UNLOCK(), which provide a single level dialplan
1517 mutex. No deadlocks are possible, as LOCK() only allows a single lock to be
1518 held for any given channel. Also, locks are automatically freed when a
1520 * Added HINT() dialplan function that allows retrieving hint information.
1521 Hints are mappings between extensions and devices for the sake of
1522 determining the state of an extension. This function can retrieve the list
1523 of devices or the name associated with a hint.
1524 * Added EXTENSION_STATE() dialplan function which allows retrieving the state
1526 * Added SYSINFO() dialplan function which allows retrieval of system information
1527 * Added a new dialplan function, DIALPLAN_EXISTS(), which allows you to check for
1528 the existence of a dialplan target.
1529 * Added two new dialplan functions, TOUPPER and TOLOWER, which convert a string to
1530 upper and lower case, respectively.
1531 * When bridging, Asterisk sets the BRIDGEPVTCALLID to the channel drivers unique
1532 ID for the call (not the Asterisk call ID or unique ID), provided that the
1533 channel driver supports this. For SIP, you get the SIP call-ID for the
1534 bridged channel which you can store in the CDR with a custom field.
1538 * Added CLI permissions, config file: cli_permissions.conf
1539 default is to allow all commands for every local user/group.
1540 Also this new feature added three new CLI commands:
1541 - cli check permissions {<username>|@<groupname>|<username>@<groupname>} [<command>]
1542 - cli reload permissions
1543 - cli show permissions
1544 * New CLI command "core show hint" (usage: core show hint <exten>)
1545 * New CLI command "core show settings"
1546 * Added 'core show channels count' CLI command.
1547 * Added the ability to set the core debug and verbose values on a per-file basis.
1548 * Added 'queue pause member' and 'queue unpause member' CLI commands
1549 * Ability to set process limits ("ulimit") without restarting Asterisk
1550 * Enhanced "agi debug" to print the channel name as a prefix to the debug
1551 output to make debugging on busy systems much easier.
1552 * New CLI commands "dialplan set extenpatternmatching true/false"
1553 * New CLI command: "core set chanvar" to set a channel variable from the CLI.
1554 * Added an easy way to execute Asterisk CLI commands at startup. Any commands
1555 listed in the startup_commands section of cli.conf will get executed.
1556 * Added a CLI command, "devstate change", which allows you to set custom device
1557 states from the func_devstate module that provides the DEVICE_STATE() function
1558 and handling of the "Custom:" devices.
1559 * New CLI command: "sip show sched" which shows all ast_sched entries for sip,
1560 sorted into the different possible callbacks, with the number of entries
1561 currently scheduled for each. Gives you a feel for how busy the sip channel
1563 * Added 'skinny show lines verbose' CLI command. This will show the subs for every channel.
1564 * Cleanup another bunch of CLI commands. Now all modules follow the same schema.
1565 (Done by lmadsen, junky and mvanbaak during the devcon 2008)
1569 * Added a new 'faxdetect=yes|no' configuration option to sip.conf. When this
1570 option is enabled, Asterisk will watch for a CNG tone in the incoming audio
1571 for a received call. If it is detected, the channel will jump to the
1572 'fax' extension in the dialplan.
1573 * The default SIP useragent= identifier now includes the Asterisk version
1574 * A new option, match_auth_username in sip.conf changes the matching of incoming requests.
1575 If set, and the incoming request carries authentication info,
1576 the username to match in the users list is taken from the Digest header
1577 rather than from the From: field. This feature is considered experimental.
1578 * The "musiconhold" and "musicclass" settings in sip.conf are now removed,
1579 since they where replaced by "mohsuggest" and "mohinterpret" in version 1.4
1580 * The "localmask" setting was removed in version 1.2 and the reminder about it
1581 being removed is now also removed.
1582 * A new option "busylevel" for setting a level of calls where asterisk reports
1583 a device as busy, to separate it from call-limit. This value is also added
1584 to the SIP_PEER dialplan function.
1585 * A new realtime family called "sipregs" is now supported to store SIP registration
1586 data. If this family is defined, "sippeers" will be used for configuration and
1587 "sipregs" for registrations. If it's not defined, "sippeers" will be used for
1588 registration data, as before.
1589 * The SIPPEER function have new options for port address, call and pickup groups
1590 * Added support for T.140 realtime text in SIP/RTP
1591 * The "checkmwi" option has been removed from sip.conf, as it is no longer
1592 required due to the restructuring of how MWI is handled. See the descriptions
1593 in this file of the "pollmailboxes" and "pollfreq" options to voicemail.conf
1594 for more information.
1595 * Added rtpdest option to CHANNEL() dialplan function.
1596 * Added SIPREFERRINGCONTEXT and SIPREFERREDBYHDR variables which are set when a transfer takes place.
1597 * SIP now adds a header to the CANCEL if the call was answered by another phone
1598 in the same dial command, or if the new c option in dial() is used.
1599 * The new default is that 100 Trying is not sent on REGISTER attempts as the RFC specifically
1600 states it is not needed. For phones, however, that do require it the "registertrying" option
1601 has been added so it can be enabled.
1602 * A new option called "callcounter" (global/peer/user level) enables call counters needed
1603 for better status reports needed for queues and SIP subscriptions. (Call-Limit was previously
1604 used to enable this functionality).
1605 * New settings for timer T1 and timer B on a global level or per device. This makes it
1606 possible to force timeout faster on non-responsive SIP servers. These settings are
1607 considered advanced, so don't use them unless you have a problem.
1608 * Added a dial string option to be able to set the To: header in an INVITE to any
1610 * Added a new global and per-peer option, qualifyfreq, which allows you to configure
1611 the qualify frequency.
1612 * Added SIP Session Timers support (RFC 4028). This prevents stuck SIP sessions that
1613 were not properly torn down due to network or endpoint failures during an established
1615 * Added experimental TCP and TLS support for SIP. See doc/siptls.txt and
1616 configs/sip.conf.sample for more information on how it is used.
1617 * Added a new configuration option "authfailureevents" that enables manager events when
1618 a peer can't authenticate properly.
1619 * Added DNS manager support to registrations for peers not referencing a peer entry.
1623 * Added the trunkmaxsize configuration option to chan_iax2.
1624 * Added the srvlookup option to iax.conf
1625 * Added support for OSP. The token is set and retrieved through the CHANNEL()
1628 XMPP Google Talk/Jingle changes
1629 -------------------------------
1630 * Added the bindaddr option to gtalk.conf.
1634 * Added skinny show device, skinny show line, and skinny show settings CLI commands.
1635 * Proper codec support in chan_skinny.
1636 * Added settings for IP and Ethernet QoS requests
1640 * Added separate settings for media QoS in mgcp.conf
1642 Console Channel Driver changes
1643 ------------------------------
1644 * Added experimental support for video send & receive to chan_oss.
1645 This requires SDL and ffmpeg/avcodec, plus Video4Linux or X11 to act as
1648 Phone channel changes (chan_phone)
1649 ----------------------------------
1650 * Added G729 passthrough support to chan_phone for Sigma Designs boards.
1652 H.323 channel Changes
1653 ---------------------
1654 * H323 remote hold notification support added (by NOTIFY message
1655 and/or H.450 supplementary service)
1657 Local channel changes
1658 ---------------------
1659 * The device state functionality in the Local channel driver has been updated
1660 to indicate INUSE or NOT_INUSE when a Local channel is being used as opposed
1661 to just UNKNOWN if the extension exists.
1662 * Added jitterbuffer support for chan_local. This allows you to use the
1663 generic jitterbuffer on incoming calls going to Asterisk applications.
1664 For example, this would allow you to use a jitterbuffer for an incoming
1665 SIP call to Voicemail by putting a Local channel in the middle. This
1666 feature is enabled by using the 'j' option in the Dial string to the Local
1667 channel in conjunction with the existing 'n' option for local channels.
1668 * A 'b' option has been added which causes chan_local to return the actual channel
1669 that is behind it when queried. This is useful for transfer scenarios as the
1670 actual channel will be transferred, not the Local channel.
1672 Agent channel changes
1673 ----------------------
1674 * The ackcall and endcall options are now supplemented with options acceptdtmf
1675 and enddtmf. These allow for the DTMF keypress to be configurable. The options
1676 default to their old hard-coded values ('#' and '*' respectively) so this should
1677 not break any existing agent installations.
1679 DAHDI channel driver (chan_dahdi) Changes
1680 ----------------------------------------
1681 * SS7 support (via libss7 library)
1682 * In India, some carriers transmit CID via dtmf. Some code has been added
1683 that will handle some situations. The cidstart=polarity_IN choice has been added for
1684 those carriers that transmit CID via dtmf after a polarity change.
1685 * CID matching information is now shown when doing 'dialplan show'.
1686 * Added dahdi show version CLI command.
1687 * Added setvar support to chan_dahdi.conf channel entries.
1688 * Added two new options: mwimonitor and mwimonitornotify. These options allow
1689 you to enable MWI monitoring on FXO lines. When the MWI state changes,
1690 the script specified in the mwimonitornotify option is executed. An internal
1691 event indicating the new state of the mailbox is also generated, so that
1692 the normal MWI facilities in Asterisk work as usual.
1693 * Added signalling type 'auto', which attempts to use the same signalling type
1694 for a channel as configured in DAHDI. This is primarily designed for analog
1695 ports, but will also work for digital ports that are configured for FXS or FXO
1696 signalling types. This mode is also the default now, so if your chan_dahdi.conf
1697 does not specify signalling for a channel (which is unlikely as the sample
1698 configuration file has always recommended specifying it for every channel) then
1699 the 'auto' mode will be used for that channel if possible.
1700 * Added a 'dahdi set dnd' command to allow CLI control of the Do-Not-Disturb
1701 state for a channel; also ensured that the DNDState Manager event is
1702 emitted no matter how the DND state is set or cleared.
1706 * Added a new channel driver, chan_unistim. See doc/unistim.txt and
1707 configs/unistim.conf.sample for details. This new channel driver allows
1708 you to use Nortel i2002, i2004, and i2050 phones with Asterisk.
1709 * Added a new channel driver, chan_console, which uses portaudio as a cross
1710 platform audio interface. It was written as a channel driver that would
1711 work with Mac CoreAudio, but portaudio supports a number of other audio
1712 interfaces, as well. Note that this channel driver requires v19 or higher
1713 of portaudio; older versions have a different API.
1717 * Added the ability to specify arguments to the Dial application when using
1718 the DUNDi switch in the dialplan.
1719 * Added the ability to set weights for responses dynamically. This can be
1720 done using a global variable or a dialplan function. Using the SHELL()
1721 function would allow you to have an external script set the weight for
1723 * Added two new dialplan functions, DUNDIQUERY and DUNDIRESULT. These
1724 functions will allow you to initiate a DUNDi query from the dialplan,
1725 find out how many results there are, and access each one.
1726 * Added the ability to specifiy a port for a dundi peer.
1730 * Added two new dialplan functions, ENUMQUERY and ENUMRESULT. These
1731 functions will allow you to initiate an ENUM lookup from the dialplan,
1732 and Asterisk will cache the results. ENUMRESULT can be used to access
1733 the results without doing multiple DNS queries.
1737 * Added the ability to customize which sound files are used for some of the
1738 prompts within the Voicemail application by changing them in voicemail.conf
1739 * Added the ability for the "voicemail show users" CLI command to show users
1740 configured by the dynamic realtime configuration method.
1741 * MWI (Message Waiting Indication) handling has been significantly
1742 restructured internally to Asterisk. It is now totally event based
1743 instead of polling based. The voicemail application will notify other
1744 modules that have subscribed to MWI events when something in the mailbox
1746 This also means that if any other entity outside of Asterisk is changing
1747 the contents of mailboxes, then the voicemail application still needs to
1748 poll for changes. Examples of situations that would require this option
1749 are web interfaces to voicemail or an email client in the case of using
1750 IMAP storage. So, two new options have been added to voicemail.conf
1751 to account for this: "pollmailboxes" and "pollfreq". See the sample
1752 configuration file for details.
1753 * Added "tw" language support
1754 * Added support for storage of greetings using an IMAP server
1755 * Added ability to customize forward, reverse, stop, and pause keys for message playback
1756 * SMDI is now enabled in voicemail using the smdienable option.
1757 * A "lockmode" option has been added to asterisk.conf to configure the file
1758 locking method used for voicemail, and potentially other things in the
1759 future. The default is the old behavior, lockfile. However, there is a
1760 new method, "flock", that uses a different method for situations where the
1761 lockfile will not work, such as on SMB/CIFS mounts.
1762 * Added the ability to backup deleted messages, to ease recovery in the case
1763 that a user accidentally deletes a message, and discovers that they need it.
1764 * Reworked the SMDI interface in Asterisk. The new way to access SMDI information
1765 is through the new functions, SMDI_MSG_RETRIEVE() and SMDI_MSG(). The file
1766 smdi.conf can now be configured with options to map SMDI station IDs to Asterisk
1767 voicemail boxes. The SMDI interface can also poll for MWI changes when some
1768 outside entity is modifying the state of the mailbox (such as IMAP storage or
1769 a web interface of some kind).
1770 * Added the support for marking messages as "urgent." There are two methods to accomplish
1771 this. One is to pass the 'U' option to VoiceMail(). Another way to mark a message as urgent
1772 is to specify "review=yes" in voicemail.conf. Doing this will cause allow the user to mark
1773 the message as urgent after he has recorded a voicemail by following the voice instructions.
1774 When listening to voicemails using VoiceMailMain urgent messages will be presented before other
1779 * Added the general option 'shared_lastcall' so that member's wrapuptime may be
1780 used across multiple queues.
1781 * Added QUEUE_VARIABLES function to set queue variables added setqueuevar and
1782 setqueueentryvar options for each queue, see queues.conf.sample for details.
1783 * Added keepstats option to queues.conf which will keep queue
1784 statistics during a reload.
1785 * setinterfacevar option in queues.conf also now sets a variable
1786 called MEMBERNAME which contains the member's name.
1787 * Added 'Strategy' field to manager event QueueParams which represents
1788 the queue strategy in use.
1789 * Added option to run macro when a queue member is connected to a caller,
1790 see queues.conf.sample for details.
1791 * app_queue now has a 'loose' option which is almost exactly like 'strict' except it
1792 does not count paused queue members as unavailable.
1793 * Added min-announce-frequency option to queues.conf which allows you to control the
1794 minimum amount of time between queue announcements for use when the caller's queue
1795 position changes frequently.
1796 * Added additional information to EXITWITHTIMEOUT and EXITWITHKEY events in the
1798 * Added ability for non-realtime queues to have realtime members
1799 * Added the "linear" strategy to queues.
1800 * Added the "wrandom" strategy to queues.
1801 * Added new channel variable QUEUE_MIN_PENALTY
1802 * QUEUE_MAX_PENALTY and QUEUE_MIN_PENALTY may be adjusted in mid-call by defining
1803 rules in queuerules.conf. See configs/queuerules.conf.sample for details
1804 * Added a new parameter for member definition, called state_interface. This may be
1805 used so that a member may be called via one interface but have a different interface's
1806 device state reported.
1807 * Added new CLI and Manager commands relating to reloading queues. From the CLI, see
1808 "queue reload", "queue reset stats". Also see "manager show command QueueReload" and
1809 "manager show command QueueReset."
1810 * New configuration option: randomperiodicannounce. If a list of periodic announcements is
1811 specified by the periodic-announce option, then one will be chosen randomly when it is time
1812 to play a periodic announcment
1813 * New configuration options: announce-position now takes two more values in addition to "yes" and
1814 "no." Two new options, "limit" and "more," are allowed. These are tied to another option,
1815 announce-position-limit. By setting announce-position to "limit" callers will only have their
1816 position announced if their position is less than what is specified by announce-position-limit.
1817 If announce-position is set to "more" then callers beyond the position specified by announce-position-limit
1818 will be told that their are more than announce-position-limit callers waiting.
1819 * Two new queue log events have been added. An ADDMEMBER event will be logged
1820 when a realtime queue member is added and a REMOVEMEMBER event will be logged
1821 when a realtime queue member is removed. Since there is no calling channel associated
1822 with these events, the string "REALTIME" is placed where the channel's unique id
1823 is typically placed.
1824 * The configuration method for the "joinempty" and "leavewhenempty" options has
1825 changed to a comma-separated list of methods of determining member availability
1826 instead of vague terms such as "yes," "loose," "no," and "strict." These old four
1827 values are still accepted for backwards-compatibility, though.
1828 * The average talktime is now calculated on queues. This information is reported via the
1829 CLI commands "queue show" and "queues show"; through the AMI events AgentComplete, QueueSummary,
1830 and QueueParams; and through the channelvariable QUEUETALKTIME if setinterfacevar=yes is set for
1835 * The 'o' option to provide an optimization has been removed and its functionality
1836 has been enabled by default.
1837 * When a conference is created, the UNIQUEID of the channel that caused it to be
1838 created is stored. Then, every channel that joins the conference will have the
1839 MEETMEUNIQUEID channel variable set with this ID. This can be used to relate
1840 callers that come and go from long standing conferences.
1841 * Added a new application, MeetMeChannelAdmin, which is similar to MeetMeAdmin,
1842 except it does operations on a channel by name, instead of number in a conference.
1843 This is a very useful feature in combination with the 'X' option to ChanSpy.
1844 * Added 'C' option to Meetme which causes a caller to continue in the dialplan
1846 * Added new RealTime functionality to provide support for scheduled conferencing.
1847 This includes optional messages to the caller if they attempt to join before
1848 the schedule start time, or to allow the caller to join the conference early.
1849 Also included is optional support for limiting the number of callers per
1850 RealTime conference.
1851 * Added the S() and L() options to the MeetMe application. These are pretty
1852 much identical to the S() and L() options to Dial(). They let you set
1853 timeouts for the conference, as well as have warning sounds played to
1854 let the caller know how much time is left, and when it is running out.
1855 * Added the ability to do "meetme concise" with the "meetme" CLI command.
1856 This extends the concise capabilities of this CLI command to include
1857 listing all conferences, instead of an addition to the other sub commands
1858 for the "meetme" command.
1859 * Added the ability to specify the music on hold class used to play into the
1860 conference when there is only one member and the M option is used.
1861 * Added MEETME_INFO dialplan function which provides a way to query
1862 various properties of a Meetme conference.
1863 * Added new admin features: *81: Roll call, *82: eject all, *83: mute all,
1864 and *84: record in-conf
1866 Other Dialplan Application Changes
1867 ----------------------------------
1868 * Argument support for Gosub application
1869 * From the to-do lists: straighten out the app timeout args:
1870 Wait() app now really does 0.3 seconds- was truncating arg to an int.
1871 WaitExten() same as Wait().
1872 Congestion() - Now takes floating pt. argument.
1873 Busy() - now takes floating pt. argument.
1874 Read() - timeout now can be floating pt.
1875 WaitForRing() now takes floating pt timeout arg.
1876 SpeechBackground() -- clarified in the docstrings that the timeout is an integer seconds.
1877 * Added 's' option to Page application.
1878 * Added an optional timeout argument to the Page application.
1879 * Added 'E', 'V', and 'P' commands to ExternalIVR.
1880 * Added 'o' and 'X' options to Chanspy.
1881 * Added a new dialplan application, Bridge, which allows you to bridge the
1882 calling channel to any other active channel on the system.
1883 * Added the ability to specify a music on hold class to play instead of ringing
1884 for the SLATrunk application.
1885 * The Read application no longer exits the dialplan on error. Instead, it sets
1886 READSTATUS to ERROR, which you can catch and handle separately.
1887 * Added 'm' option to Directory, which lists out names, 8 at a time, instead
1888 of asking for verification of each name, one at a time.
1889 * Privacy() no longer uses privacy.conf, as all options are specifyable as
1890 direct options to the app.
1891 * AMD() has a new "maximum word length" option. "show application AMD" from the CLI
1893 * GotoIfTime() now may branch based on a "false" condition, like other Goto-related applications
1894 * The ChannelRedirect application no longer exits the dialplan if the given channel
1895 does not exist. It will now set the CHANNELREDIRECT_STATUS variable to SUCCESS upon success
1896 or NOCHANNEL if the given channel was not found.
1897 * The silencethreshold setting that was previously configurable in multiple
1898 applications is now settable globally via dsp.conf.
1900 Music On Hold Changes
1901 ---------------------
1902 * A new option, "digit", has been added for music on hold classes in
1903 musiconhold.conf. If this is set for a music on hold class, a caller
1904 listening to music on hold can press this digit to switch to listening
1905 to this music on hold class.
1906 * Support for realtime music on hold has been added.
1907 * In conjunction with the realtime music on hold, a general section has
1908 been added to musiconhold.conf, its sole variable is cachertclasses. If this
1909 is set, then music on hold classes found in realtime will be cached in memory.
1913 * AEL upgraded to use the Gosub with Arguments instead
1914 of Macro application, to hopefully reduce the problems
1915 seen with the artificially low stack ceiling that
1916 Macro bumps into. Macros can only call other Macros
1917 to a depth of 7. Tests run using gosub, show depths
1918 limited only by virtual memory. A small test demonstrated
1919 recursive call depths of 100,000 without problems.
1920 -- in addition to this, all apps that allowed a macro
1921 to be called, as in Dial, queues, etc, are now allowing
1922 a gosub call in similar fashion.
1923 * AEL now generates LOCAL(argname) declarations when it
1924 Set()'s the each arg name to the value of ${ARG1}, ${ARG2),
1925 etc. That makes the arguments local in scope. The user
1926 can define their own local variables in macros, now,
1927 by saying "local myvar=someval;" or using Set() in this
1928 fashion: Set(LOCAL(myvar)=someval); ("local" is now
1930 * utils/conf2ael introduced. Will convert an extensions.conf
1931 file into extensions.ael. Very crude and unfinished, but
1932 will be improved as time goes by. Should be useful for a
1933 first pass at conversion.
1934 * aelparse will now read extensions.conf to see if a referenced
1935 macro or context is there before issueing a warning.
1936 * AEL parser sets a local channel variable ~~EXTEN~~, to
1937 preserve the value of ${EXTEN} thru switch statements.
1938 * New operator in $[...] expressions: the ~~ operator serves
1939 as a concatenation operator. AT THE MOMENT, it is really only
1940 necessary and useful in AEL, especially in if() expressions.
1941 Operation: ${a} ~~ ${b| with force both a and b to strings, strip
1942 any enclosing double-quotes, and evaluate to the value of a
1943 concatenated with the value of b. For example if a is set to
1944 "xyz" and b has the value "abc", then ${a} ~~ ${b| would
1945 evaluate to xyzabc .
1948 Call Features (res_features) Changes
1949 ------------------------------------
1950 * Added the parkedcalltransfers option to features.conf
1951 * Added parkedcallparking option to control one touch parking w/ parking
1953 * Added parkedcallhangup option to control disconnect feature w/ parking
1955 * Added parkedcallrecording option to control one-touch record w/ parking
1957 * Added parkedcallparking, parkedcallhangup, parkedcallrecording, and
1958 parkedcalltransfers option support for multiple parking lots.
1959 * Added BRIDGE_FEATURES variable to set available features for a channel
1960 * The built-in method for doing attended transfers has been updated to
1961 include some new options that allow you to have the transferee sent
1962 back to the person that did the transfer if the transfer is not successful.
1963 See the options "atxferdropcall", "atxferloopdelay", and "atxfercallbackretries"
1964 in features.conf.sample.
1965 * Added support for configuring named groups of custom call features in
1966 features.conf. This means that features can be written a single time, and
1967 then mapped into groups of features for different key mappings or easier
1969 * Updated the ParkedCall application to allow you to not specify a parking
1970 extension. If you don't specify a parking space to pick up, it will grab
1971 the first one available.
1972 * Added cli command 'features reload' to reload call features from features.conf
1973 * Moved into core asterisk binary.
1974 * Changed the default setting for featuredigittimeout to 2000 ms from 500 ms.
1975 * Added the ability for custom parking lots to be configured with their own
1976 parking extension with the parkext option.
1978 Language Support Changes
1979 ------------------------
1980 * Brazilian Portuguese (pt-BR) in VM, and say.c was added
1981 * Added support for the Hungarian language for saying numbers, dates, and times.
1985 * Added SPEECH commands for speech recognition. A complete listing can be found
1987 * If app_stack is loaded, GOSUB is a native AGI command that may be used to
1988 invoke subroutines in the dialplan. Note that calling EXEC with Gosub
1989 does not behave as expected; the native command needs to be used, instead.
1990 * Added the ability to perform SRV lookups on fast AGI calls. To use this
1991 feature, simply use hagi: instead of agi: as the protocol portion
1992 of the URI parameter to the AGI function call in your dial plan. Also note
1993 that specifying a port number in the AGI URI will disable SRV lookups,
1994 even if you use the hagi: protocol.
1995 * No longer support MSG_OOB flag on HANGUP.
1999 * Added rotatestrategy option to logger.conf, along with two new options:
2000 "timestamp" which will use the time to name the logger files instead of
2001 sequence number; and "rotate", which rotates the names of the log files,
2002 similar to the way syslog rotates files.
2003 * Added exec_after_rotate option to logger.conf, which allows a system
2004 command to be run after rotation. This is primarily useful with
2005 rotatestrategy=rotate, to allow a limit on the number of log files kept
2006 and to ensure that the oldest log file gets deleted.
2007 * Added realtime support for the queue log
2011 * The cdr_manager module has a [mappings] feature, like cdr_custom,
2012 to add fields to the manager event from the CDR variables.
2013 * Added cdr_adaptive_odbc, a new module that adapts to the structure of your
2014 backend database CDR table. Specifically, additional, non-standard
2015 columns are supported, merely by setting the corresponding CDR variable in
2016 your dialplan. In addition, you may alias any column to another name (for
2017 example, if you want the 'src' CDR variable to be column 'ANI' in the DB,
2018 simply "alias src => ANI" in the configuration file). Records may be
2019 posted to more than one backend, simply by specifying multiple categories
2020 in the configuration file. And finally, you may filter which CDRs get
2021 posted to each backend, by specifying a filter (which the record must
2022 match) for the particular category. Filters are additive (meaning all
2023 rules must match to post that CDR).
2024 * The Postgres CDR module now supports some features of the cdr_adaptive_odbc
2025 module. Specifically, you may add additional columns into the table and
2026 they will be set, if you set the corresponding CDR variable name. Also,
2027 if you omit columns in your database table, they will be silently skipped
2028 (but a record will still be inserted, based on what columns remain). Note
2029 that the other two features from cdr_adaptive_odbc (alias and filter) are
2030 not currently supported.
2031 * The ResetCDR application now has an 'e' option that re-enables a CDR if it
2032 has been disabled using the NoCDR application.
2034 Miscellaneous New Modules
2035 -------------------------
2036 * Added a new CDR module, cdr_sqlite3_custom.
2037 * Added a new realtime configuration module, res_config_sqlite
2038 * Added a new codec translation module, codec_resample, which re-samples
2039 signed linear audio between 8 kHz and 16 kHz to help support wideband
2041 * Added a new module, res_phoneprov, which allows auto-provisioning of phones
2042 based on configuration templates that use Asterisk dialplan function and
2043 variable substitution. It should be possible to create phone profiles and
2044 templates that work for the majority of phones provisioned over http. It
2045 is currently only intended to provision a single user account per phone.
2046 An example profile and set of templates for Polycom phones is provided.
2047 NOTE: Polycom firmware is not included, but should be placed in
2048 AST_DATA_DIR/phoneprov/configs to match up with the included templates.
2049 * Added a new module, app_jack, which provides interfaces to JACK, the Jack
2050 Audio Connection Kit (http://www.jackaudio.org/). Two interfaces are
2051 provided; there is a JACK() application, and a JACK_HOOK() function. Both
2052 interfaces create an input and output JACK port. The application makes
2053 these ports the endpoint of the call. The audio coming from the channel
2054 goes out the output port and whatever comes back in on the input port is
2055 what gets sent to the channel. The JACK_HOOK() function turns on a JACK
2056 audiohook on the channel. This lets you run the audio coming from a
2057 channel through JACK, and whatever comes back in is what gets forwarded
2058 on as the channel's audio. This is very useful for building custom
2059 vocoders or doing recording or analysis of the channel's audio in another
2061 * Added a new module, res_config_curl, which permits using a HTTP POST url
2062 to retrieve, create, update, and delete realtime information from a remote
2063 web server. Note that this module requires func_curl.so to be loaded for
2064 backend functionality.
2065 * Added a new module, res_config_ldap, which permits the use of an LDAP
2066 server for realtime data access.
2067 * Added support for writing and running your dialplan in lua using the pbx_lua
2068 module. See configs/extensions.lua.sample for examples of how to do this.
2072 * Ability to use libcap to set high ToS bits when non-root
2073 on Linux. If configure is unable to find libcap then you
2074 can use --with-cap to specify the path.
2075 * Added maxfiles option to options section of asterisk.conf which allows you to specify
2076 what Asterisk should set as the maximum number of open files when it loads.
2077 * Added the jittertargetextra configuration option.
2078 * Added support for setting the CoS for VLAN traffic (802.1p). See the sample
2079 configuration files for the IP channel drivers. The new option is "cos".
2080 This information is also documented in doc/qos.tex, or the IP Quality of Service
2081 section of asterisk.pdf.
2082 * When originating a call using AMI or pbx_spool that fails the reason for failure
2083 will now be available in the failed extension using the REASON dialplan variable.
2084 * Added support for reading the TOUCH_MONITOR_PREFIX channel variable.
2085 It allows you to configure a prefix for auto-monitor recordings.
2086 * A new extension pattern matching algorithm, based on a trie, is introduced
2087 here, that could noticeably speed up mid-sized to large dialplans.
2088 It is NOT used by default, as duplicating the behaviour of the old pattern
2089 matcher is still under development. A config file option, in extensions.conf,
2090 in the [general] section, called "extenpatternmatchingnew", is by default
2091 set to false; setting that to true will force the use of the new algorithm.
2092 Also, the cli commands "dialplan set extenpatternmatchingnew true/false" can
2093 be used to switch the algorithms at run time.
2094 * A new option when starting a remote asterisk (rasterisk, asterisk -r) for
2095 specifying which socket to use to connect to the running Asterisk daemon
2097 * Performance enhancements to the sched facility, which is used in
2098 the channel drivers, etc. Added hashtabs and doubly-linked lists
2099 to speed up deletion; start at the beginning or end of list to
2101 * Added Doubly-linked lists after the fashion of linkedlists.h. They are in
2102 dlinkedlists.h. Doubly-linked lists feature fast deletion times.
2103 Added regression tests to the tests/ dir, also.
2104 * Added a refcount trace feature to astobj2 for those trying to balance
2105 object creation, deletion; work, play; space and time. See the
2106 notes in astobj2.h. Also, see utils/refcounter as well, as a
2107 quick way to find unbalanced refcounts in what could be a sea
2108 of objects that were balanced.
2109 * Added logging to 'make update' command. See update.log
2110 * Added strictrtp option to rtp.conf. If enabled this will drop RTP packets that
2111 do not come from the remote party.
2112 * Added the 'n' option to the SpeechBackground application to tell it to not
2113 answer the channel if it has not already been answered.
2114 * Added a compiler flag, CHANNEL_TRACE, which permits channel tracing to be
2115 turned on, via the CHANNEL(trace) dialplan function. Could be useful for
2117 * iLBC source code no longer included (see UPGRADE.txt for details)
2118 * If compiled with DETECT_DEADLOCKS enabled and if you have glibc, then if
2119 deadlock is detected, a backtrace of the stack which led to the lock calls
2120 will be output to the CLI.
2121 * If compiled with DEBUG_THREADS enabled and if you have glibc, then issuing
2122 the "core show locks" CLI command will give lock information output as well
2123 as a backtrace of the stack which led to the lock calls.
2124 * users.conf now sports an optional alternateexts property, which permits
2125 allocation of additional extensions which will reach the specified user.
2126 * A new option for the configure script, --enable-internal-poll, has been added
2127 for use with systems which may have a buggy implementation of the poll system
2128 call. If you notice odd behavior such as the CLI being unresponsive on remote
2129 consoles, you may want to try using this option. This option is enabled by default
2130 on Darwin systems since it is known that the Darwin poll() implementation has
2134 --------------------
2135 * In addition to timing from DAHDI, there is a new timing module called
2136 res_timing_timerfd. In order to use this, you must be running Linux with
2137 a kernel version 2.6.25 or newer as well as glibc 2.8 or newer. The configure
2138 script will be able to tell if you have the requirements. From menuselect, select
2139 res_timing_timerfd from the Resource Modules menu.
