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 1.8 to Asterisk 1.10 -----------------
13 ------------------------------------------------------------------------------
17 * parkedmusicclass can now be set for non-default parking lots.
18 * ParkedCall application can now specify a specific parkinglot.
20 Asterisk Manager Interface
21 --------------------------
22 * PeerStatus now includes Address and Port.
23 * Added Hold events for when the remote party puts the call on and off hold
24 for chan_dahdi ISDN channels.
25 * Added new action MeetmeListRooms to list active conferences (shows same
26 data as "meetme list" at the CLI).
27 * DAHDIShowChannels, SIPshowpeer, SIPpeers, and IAXpeers now contains a
28 Description field that is set by 'description' in the channel configuration
30 * Added Uniqueid header to UserEvent.
33 --------------------------
34 * The HTTP Server can bind to IPv6 addresses.
37 --------------------------
38 * Busy tone patterns featuring 2 silence and 2 tone lengths can now be used
39 with busydetect. usage example: busypattern=200,200,200,600
42 --------------------------
43 * New 'gtalk show settings' command showing the current settings loaded from
45 * The 'logger reload' command now supports an optional argument, specifying an
46 alternate configuration file to use.
47 * 'dialplan add extension' command will now automatically create a context if
48 the specified context does not exist with a message indicated it did so.
49 * 'sip show peers', 'iax show peers', and 'dahdi show peers' now contains a
50 Description field which can be populated with 'description' in the channel
51 configuration files (sip.conf, iax2.conf, and chan_dahdi.conf).
54 --------------------------
55 * The filter option in cdr_adaptive_odbc now supports negating the argument,
56 thus allowing records which do NOT match the specified filter.
59 --------------------------
60 * Ability to define custom SILK formats in codecs.conf.
61 * Addition of speex32 audio format with translation.
64 --------------------------
65 * New highly optimized and customizable ConfBridge application capable of
66 mixing audio at sample rates ranging from 8khz-96khz.
67 * CONFBRIDGE dialplan function capable of creating dynamic ConfBridge user
68 and bridge profiles on a channel.
72 * Added ASTETCDIR, ASTMODDIR, ASTVARLIBDIR, ASTDBDIR, ASTKEYDIR, ASTDATADIR,
73 ASTAGIDIR, ASTSPOOLDIR, ASTRUNDIR, ASTLOGDIR which hold the equivalent
74 variables from asterisk.conf.
78 * Addition of the JITTERBUFFER dialplan function. This function allows
79 for jitterbuffering to occur on the read side of a channel. By using
80 this function conference applications such as ConfBridge and MeetMe can
81 have the rx streams jitterbuffered before conference mixing occurs.
82 * Added DB_KEYS, which lists the next set of keys in the Asterisk database
84 * Added STRREPLACE function. This function let's the user search a variable
85 for a given string to replace with another string as many times as the
86 user specifies or just throughout the whole string.
88 libpri channel driver (chan_dahdi) DAHDI changes
89 --------------------------
90 * Added moh_signaling option to specify what to do when the channel's bridged
91 peer puts the ISDN channel on hold.
92 * Added display_send and display_receive options to control how the display ie
93 is handled. To send display text from the dialplan use the SendText()
94 application when the option is enabled.
95 * Added mcid_send option to allow sending a MCID request on a span.
98 --------------------------
99 * Added setvar option to calendar.conf to allow setting channel variables on
100 notification channels.
101 * Added "calendar show types" CLI command to list registered calendar
105 --------------------------
106 * Added two new options, r and t with file name arguments to record
107 single direction (unmixed) audio recording separate from the bidirectional
108 (mixed) recording. The mixed file name argument is optional now as long
109 as at least one recording option is used.
112 --------------------------
113 * Added a new option, l, which will disable local call optimization for
114 channels involved with the FollowMe thread. Use this option to improve
115 compatability for a FollowMe call with certain dialplan apps, options, and
119 --------------------------
120 * cel_pgsql now supports the 'extra' column for data added using the
121 CELGenUserEvent() application.
124 --------------------------
125 * Support for defining hints has been added to pbx_lua. See the 'hints' table
126 in the sample extensions.lua file for syntax details.
127 * Applications that perform jumps in the dialplan such as Goto will now
128 execute properly. When pbx_lua detects that the context, extension, or
129 priority we are executing on has changed it will immediatly return control
130 to the asterisk PBX engine. Currently the engine cannot detect a Goto to
131 the priority after the currently executing priority.
132 * An autoservice is now started by default for pbx_lua channels. It can be
133 stopped and restarted using the autoservice_stop() and autoservice_start()
136 ------------------------------------------------------------------------------
137 --- Functionality changes from Asterisk 1.6.2 to Asterisk 1.8 ----------------
138 ------------------------------------------------------------------------------
142 * Added preferred_codec_only option in sip.conf. This feature limits the joint
143 codecs sent in response to an INVITE to the single most preferred codec.
144 * Added SIP_CODEC_OUTBOUND dialplan variable which can be used to set the codec
145 to be used for the outgoing call. It must be one of the codecs configured
147 * Added tlsprivatekey option to sip.conf. This allows a separate .pem file
148 to be used for holding a private key. If tlsprivatekey is not specified,
149 tlscertfile is searched for both public and private key.
150 * Added tlsclientmethod option to sip.conf. This allows the protocol for
151 outbound client connections to be specified.
152 * The sendrpid parameter has been expanded to include the options
153 'rpid' and 'pai'. Setting sendrpid to 'rpid' will cause Remote-Party-ID
154 header to be sent (equivalent to setting sendrpid=yes) and setting
155 sendrpid to 'pai' will cause P-Asserted-Identity header to be sent.
156 * The 'ignoresdpversion' behavior has been made automatic when the SDP received
157 is in response to a T.38 re-INVITE that Asterisk initiated. In this situation,
158 since the call will fail if Asterisk does not process the incoming SDP, Asterisk
159 will accept the SDP even if the SDP version number is not properly incremented,
160 but will generate a warning in the log indicating that the SIP peer that sent
161 the SDP should have the 'ignoresdpversion' option set.
162 * The 'nat' option has now been been changed to have yes, no, force_rport, and
163 comedia as valid values. Setting it to yes forces RFC 3581 behavior and enables
164 symmetric RTP support. Setting it to no only enables RFC 3581 behavior if the
165 remote side requests it and disables symmetric RTP support. Setting it to
166 force_rport forces RFC 3581 behavior and disables symmetric RTP support.
167 Setting it to comedia enables RFC 3581 behavior if the remote side requests it
168 and enables symmetric RTP support.
169 * Slave SIP channels now set HASH(SIP_CAUSE,<slave-channel-name>) on each
170 response. This permits the master channel to know how each channel dialled
171 in a multi-channel setup resolved in an individual way.
172 * Added 'externtcpport' and 'externtlsport' options to allow custom port
173 configuration for the externip and externhost options when tcp or tls is used.
174 * Added support for message body (stored in content variable) to SIP NOTIFY message
175 accessible via AMI and CLI.
176 * Added 'media_address' configuration option which can be used to explicitly specify
177 the IP address to use in the SDP for media (audio, video, and text) streams.
178 * Added 'unsolicited_mailbox' configuration option which specifies the virtual mailbox
179 that the new/old count should be stored on if an unsolicited MWI NOTIFY message is
181 * Added 'use_q850_reason' configuration option for generating and parsing
182 if available Reason: Q.850;cause=<cause code> header. It is implemented
183 in some gateways for better passing PRI/SS7 cause codes via SIP.
184 * When dialing SIP peers, a new component may be added to the end of the dialstring
185 to indicate that a specific remote IP address or host should be used when dialing
186 the particular peer. The dialstring format is SIP/peer/exten/host_or_IP.
187 * SRTP SDES support for encrypting calls to/from Asterisk over SIP. The
188 ability to selectively force bridged channels to also be encrypted is also
189 implemented. Branching in the dialplan can be done based on whether or not
190 a channel has secure media and/or signaling.
191 * Added directmediapermit/directmediadeny to limit which peers can send direct media
193 * Added the 'snom_aoc_enabled' option to turn on support for sending Advice of
194 Charge messages to snom phones.
195 * Added support for G.719 media streams.
196 * Added support for 16khz signed linear media streams.
197 * SIP is now able to bind to and communicate with IPv6 addresses. In addition,
198 RTP has been outfitted with the same abilities.
199 * Added support for setting the Max-Forwards: header in SIP requests. Setting is
200 available in device configurations as well as in the dial plan.
201 * Addition of the 'subscribe_network_change' option for turning on and off
202 res_stun_monitor module support in chan_sip.
203 * Addition of the 'auth_options_requests' option for turning on and off
204 authentication for OPTIONS requests in chan_sip.
205 * Add T38 support for REJECTED state where T.38 Negotiation is explicitly rejected.
210 * Added rtsavesysname option into iax.conf to allow the systname to be saved
212 * Added the ability for chan_iax2 to inform the dialplan whether or not
213 encryption is being used. This interoperates with the SIP SRTP implementation
214 so that a secure SIP call can be bridged to a secure IAX call when the
215 dialplan requires bridged channels to be "secure".
216 * Addition of the 'subscribe_network_change' option for turning on and off
217 res_stun_monitor module support in chan_iax.
222 * Added ability to preset channel variables on indicated lines with the setvar
223 configuration option. Also, clearvars=all resets the list of variables back
225 * PacketCable NCS 1.0 support has been added for Docsis/Eurodocsis Networks.
226 See configs/res_pktccops.conf for more information.
228 XMPP Google Talk/Jingle changes
229 -------------------------------
230 * Added the externip option to gtalk.conf.
231 * Added the stunaddr option to gtalk.conf which allows for the automatic
232 retrieval of the external ip from a stun server.
236 * Added 'p' option to PickupChan() to allow for picking up channel by the first
237 match to a partial channel name.
238 * Added .m3u support for Mp3Player application.
239 * Added progress option to the app_dial D() option. When progress DTMF is
240 present, those values are sent immediately upon receiving a PROGRESS message
241 regardless if the call has been answered or not.
242 * Added functionality to the app_dial F() option to continue with execution
243 at the current location when no parameters are provided.
244 * Added the 'a' option to app_dial to answer the calling channel before any
245 announcements or macros are executed.
246 * Modified app_dial to set answertime when the called channel answers even if
247 the called channel hangs up during playback of an announcement.
248 * Modified app_dial 'r' option to support an additional parameter to play an
249 indication tone from indications.conf
250 * Added c() option to app_chanspy. This option allows custom DTMF to be set
251 to cycle through the next available channel. By default this is still '*'.
252 * Added x() option to app_chanspy. This option allows DTMF to be set to
253 exit the application.
254 * The Voicemail application has been improved to automatically ignore messages
255 that only contain silence.
256 * If you set maxmsg to 0 in voicemail.conf, Voicemail will consider the
257 associated mailbox(es) to be greetings-only.
258 * The ChanSpy application now has the 'S' option, which makes the application
259 automatically exit once it hits a point where no more channels are available
261 * The ChanSpy application also now has the 'E' option, which spies on a single
262 channel and exits when that channel hangs up.
263 * The MeetMe application now turns on the DENOISE() function by default, for
264 each participant. In our tests, this has significantly decreased background
265 noise (especially noisy data centers).
266 * Voicemail now permits storage of secrets in a separate file, located in the
267 spool directory of each individual user. The control for this is located in
268 the "passwordlocation" option in voicemail.conf. Please see the sample
269 configuration for more information.
270 * The ChanIsAvail application now exposes the returned cause code using a separate
271 variable, AVAILCAUSECODE, instead of overwriting the device state in AVAILSTATUS.
272 * Added 'd' option to app_followme. This option disables the "Please hold"
274 * Added 'y' option to app_record. This option enables a mode where any DTMF digit
275 received will terminate recording.
276 * Voicemail now supports per mailbox settings for folders when using IMAP storage.
277 Previously the folder could only be set per context, but has now been extended
278 using the imapfolder option.
279 * Voicemail now supports per mailbox settings for nextaftercmd and minsecs.
280 * Voicemail now allows the pager date format to be specified separately from the
282 * New applications JabberJoin, JabberLeave, and JabberSendGroup have been added
283 to allow joining, leaving, and sending text to group chats.
284 * MeetMe has a new option 'G' to play an announcement before joining a conference.
285 * Page has a new option 'A(x)' which will playback an announcement simultaneously
286 to all paged phones (and optionally excluding the caller's one using the new
287 option 'n') before the call is bridged.
288 * The 'f' option to Dial has been augmented to take an optional argument. If no
289 argument is provided, the 'f' option works as it always has. If an argument is
290 provided, then the connected party information of all outgoing channels created
291 during the Dial will be set to the argument passed to the 'f' option.
292 * Dial now inherits the GOSUB_RETVAL from the peer, when the U() option runs a
294 * The OSP lookup application adds in/outbound network ID, optional security,
295 number portability, QoS reporting, destination IP port, custom info and service
297 * Added new application VMSayName that will play the recorded name of the voicemail
298 user if it exists, otherwise will play the mailbox number.
299 * Added custom device states to ConfBridge bridges. Use 'confbridge:<name>' to
300 retrieve state for a particular bridge, where <name> is the conference name
301 * app_directory now allows exiting at any time using the operator or pound key.
302 * Voicemail now supports setting a locale per-mailbox.
303 * Two new applications are provided for declining counting phrases in multiple
304 languages. See the application notes for SayCountedNoun and SayCountedAdj for
306 * Voicemail now runs the externnotify script when pollmailboxes is activated and
308 * Voicemail now includes rdnis within msgXXXX.txt file.
309 * Added 'D' command to ExternalIVR full details in doc/externalivr.txt
310 * Added 'v' option to MeetMe to play voicemail greetings when a user joins/leaves
312 * Added ability to include '@parkinglot' to ParkedCall extension in order to specify
313 a specific parkinglot on which to search the extension.
317 * SRVQUERY and SRVRESULT functions added. This can be used to query and iterate
318 over SRV records associated with a specific service. From the CLI, type
319 'core show function SRVQUERY' and 'core show function SRVRESULT' for more
320 details on how these may be used.
321 * PITCH_SHIFT dialplan function added. This function can be used to modify the
322 pitch of a channel's tx and rx audio streams.
323 * Added new dialplan functions CONNECTEDLINE and REDIRECTING which permits
324 setting various connected line and redirecting party information.
325 * CALLERID and CONNECTEDLINE dialplan functions have been extended to
326 support ISDN subaddressing.
327 * The CHANNEL() function now supports the "name" and "checkhangup" options.
328 * For DAHDI channels, the CHANNEL() dialplan function now allows
329 the dialplan to request changes in the configuration of the active
330 echo canceller on the channel (if any), for the current call only.
333 exten => s,n,Set(CHANNEL(echocan_mode)=off)
335 The possible values are:
337 on - normal mode (the echo canceller is actually reinitialized)
339 fax - FAX/data mode (NLP disabled if possible, otherwise completely
341 voice - voice mode (returns from FAX mode, reverting the changes that
342 were made when FAX mode was requested)
343 * Added new dialplan function MASTER_CHANNEL(), which permits retrieving
344 and setting variables on the channel which created the current channel.
345 Administrators should take care to avoid naming conflicts, when multiple
346 channels are dialled at once, especially when used with the Local channel
347 construct (which all could set variables on the master channel). Usage
348 of the HASH() dialplan function, with the key set to the name of the slave
349 channel, is one approach that will avoid conflicts.
350 * Added new dialplan function MUTEAUDIO() for muting inbound and/or outbound
352 * func_odbc now allows multiple row results to be retrieved without using
353 mode=multirow. If rowlimit is set, then additional rows may be retrieved
354 from the same query by using the name of the function which retrieved the
355 first row as an argument to ODBC_FETCH().
356 * Added JABBER_RECEIVE, which permits receiving XMPP messages from the
357 dialplan. This function returns the content of the received message.
358 * Added REPLACE, which searches a given variable name for a set of characters,
359 then either replaces them with a single character or deletes them.
360 * Added PASSTHRU, which literally passes the same argument back as its return
361 value. The intent is to be able to use a literal string argument to
362 functions that currently require a variable name as an argument.
363 * HASH-associated variables now can be inherited across channel creation, by
364 prefixing the name of the hash at assignment with the appropriate number of
365 underscores, just like variables.
366 * GROUP_MATCH_COUNT has been improved to allow regex matching on category
367 * CHANNEL(secure_bridge_signaling) and CHANNEL(secure_bridge_media) to set/get
368 whether or not channels that are bridged to the current channel will be
369 required to have secure signaling and/or media.
370 * CHANNEL(secure_signaling) and CHANNEL(secure_media) to get whether or not
371 the current channel has secure signaling and/or media.
372 * For DAHDI/ISDN channels, the CHANNEL() dialplan function now supports the
373 "no_media_path" option.
374 Returns "0" if there is a B channel associated with the call.
375 Returns "1" if no B channel is associated with the call. The call is either
376 on hold or is a call waiting call.
377 * Added option to dialplan function CDR(), the 'f' option
378 allows for high resolution times for billsec and duration fields.
379 * FILE() now supports line-mode and writing.
380 * Added FIELDNUM(), which returns the 1-based offset of a field in a list.
381 * FRAME_TRACE(), for tracking internal ast_frames on a channel.
385 * Added DYNAMIC_FEATURENAME which holds the last triggered dynamic feature.
386 * Added DYNAMIC_PEERNAME which holds the unique channel name on the other side
387 and is set when a dynamic feature is triggered.
388 * Added PARKINGLOT which can be used with parkeddynamic feature.conf option
389 to dynamically create a new parking lot matching the value this varible is
391 * Added PARKINGDYNAMIC which represents the template parkinglot defined in
392 features.conf that should be the base for dynamic parkinglots.
393 * Added PARKINGDYNCONTEXT which tells what context a newly created dynamic
394 parkinglot should have.
395 * Added PARKINGDYNPOS which holds what parking positions a dynamic parkinglot
400 * Added "ready" option to QUEUE_MEMBER counting to count free agents whose wrap-up
402 * Added 'R' option to app_queue. This option stops moh and indicates ringing
403 to the caller when an Agent's phone is ringing. This can be used to indicate
404 to the caller that their call is about to be picked up, which is nice when
405 one has been on hold for an extened period of time.
406 * A new config option, penaltymemberslimit, has been added to queues.conf.
407 When set this option will disregard penalty settings when a queue has too
409 * A new option, 'I' has been added to both app_queue and app_dial.
410 By setting this option, Asterisk will not update the caller with
411 connected line changes or redirecting party changes when they occur.
412 * A 'relative-peroidic-announce' option has been added to queues.conf. When
413 enabled, this option will cause periodic announce times to be calculated
414 from the end of announcements rather than from the beginning.
415 * The autopause option in queues.conf can be passed a new value, "all." The
416 result is that if a member becomes auto-paused, he will be paused in all
417 queues for which he is a member, not just the queue that failed to reach
419 * Added dialplan function QUEUE_EXISTS to check if a queue exists
420 * The queue logger now allows events to optionally propagate to a file,
421 even when realtime logging is turned on. Additionally, realtime logging
422 supports sending the event arguments to 5 individual fields, although it
423 will fallback to the previous data definition, if the new table layout is
426 mISDN channel driver (chan_misdn) changes
427 ----------------------------------------
428 * Added display_connected parameter to misdn.conf to put a display string
429 in the CONNECT message containing the connected name and/or number if
430 the presentation setting permits it.
431 * Added display_setup parameter to misdn.conf to put a display string
432 in the SETUP message containing the caller name and/or number if the
433 presentation setting permits it.
434 * Made misdn.conf parameters localdialplan and cpndialplan take a -1 to
435 indicate the dialplan settings are to be obtained from the asterisk
437 * Made misdn.conf parameter callerid accept the "name" <number> format
438 used by the rest of the system.
439 * Made use the nationalprefix and internationalprefix misdn.conf
440 parameters to prefix any received number from the ISDN link if that
441 number has the corresponding Type-Of-Number. NOTE: This includes
442 comparing the incoming call's dialed number against the MSN list.
443 * Added the following new parameters: unknownprefix, netspecificprefix,
444 subscriberprefix, and abbreviatedprefix in misdn.conf to prefix any
445 received number from the ISDN link if that number has the corresponding
447 * Added new dialplan application misdn_command which permits controlling
448 the CCBS/CCNR functionality.
449 * Added new dialplan function mISDN_CC which permits retrieval of various
450 values from an active call completion record.
451 * For PTP, you should manually send the COLR of the redirected-to party
452 for an incomming redirected call if the incoming call could experience
453 further redirects. Just set the REDIRECTING(to-num,i) = ${EXTEN} and
454 set the REDIRECTING(to-pres) to the COLR. A call has been redirected
455 if the REDIRECTING(from-num) is not empty.
456 * For outgoing PTP redirected calls, you now need to use the inhibit(i)
457 option on all of the REDIRECTING statements before dialing the
458 redirected-to party. You still have to set the REDIRECTING(to-xxx,i)
459 and the REDIRECTING(from-xxx,i) values. The PTP call will update the
460 redirecting-to presentation (COLR) when it becomes available.
461 * Added outgoing_colp parameter to misdn.conf to filter outgoing COLP
464 thirdparty mISDN enhancements
465 -----------------------------
466 mISDN has been modified by Digium, Inc. to greatly expand facility message
468 * Enhanced COLP support for call diversion and transfer.
471 The latest modified mISDN v1.1.x based version is available at:
472 http://svn.digium.com/svn/thirdparty/mISDN/trunk
473 http://svn.digium.com/svn/thirdparty/mISDNuser/trunk
475 Tagged versions of the modified mISDN code are available under:
476 http://svn.digium.com/svn/thirdparty/mISDN/tags
477 http://svn.digium.com/svn/thirdparty/mISDNuser/tags
479 libpri channel driver (chan_dahdi) DAHDI changes
480 -------------------------------------------
481 * The channel variable PRIREDIRECTREASON is now just a status variable
482 and it is also deprecated. Use the REDIRECTING(reason) dialplan function
483 to read and alter the reason.
484 * For Q.SIG and ETSI PRI/BRI-PTP, you should manually send the COLR of the
485 redirected-to party for an incomming redirected call if the incoming call
486 could experience further redirects. Just set the
487 REDIRECTING(to-num,i) = CALLERID(dnid) and set the REDIRECTING(to-pres)
488 to the COLR. A call has been redirected if the REDIRECTING(count) is not
490 * For outgoing Q.SIG and ETSI PRI/BRI-PTP redirected calls, you need to
491 use the inhibit(i) option on all of the REDIRECTING statements before
492 dialing the redirected-to party. You still have to set the
493 REDIRECTING(to-xxx,i) and the REDIRECTING(from-xxx,i) values. The call
494 will update the redirecting-to presentation (COLR) when it becomes available.
495 * Added the ability to ignore calls that are not in a Multiple Subscriber
496 Number (MSN) list for PTMP CPE interfaces.
497 * Added dynamic range compression support for dahdi channels. It is
498 configured via the rxdrc and txdrc parameters in chan_dahdi.conf.
499 * Added support for ISDN calling and called subaddress with partial support
500 for connected line subaddress.
501 * Added support for BRI PTMP NT mode. (Requires latest LibPRI.)
502 * Added handling of received HOLD/RETRIEVE messages and the optional ability
503 to transfer a held call on disconnect similar to an analog phone.
504 * Added CallRerouting/CallDeflection support for Q.SIG, ETSI PTP, ETSI PTMP.
505 Will reroute/deflect an outgoing call when receive the message.
506 Can use the DAHDISendCallreroutingFacility to send the message for the
508 * Added standard location to add options to chan_dahdi dialing:
509 Dial(DAHDI/g1[/extension[/options]])
512 R Reverse charging indication
513 * Added Reverse Charging Indication (Collect calls) send/receive option.
514 Send reverse charging in SETUP message with the chan_dahdi R dialing option.
515 Dial(DAHDI/g1/extension/R)
516 Access received reverse charge in SETUP message by: ${CHANNEL(reversecharge)}
517 (requires latest LibPRI)
518 * Added ability to send/receive keypad digits in the SETUP message.
519 Send keypad digits in SETUP message with the chan_dahdi K(<keypad_digits>)
520 dialing option. Dial(DAHDI/g1/[extension]/K(<keypad_digits>))
521 Access any received keypad digits in SETUP message by: ${CHANNEL(keypad_digits)}
522 (requires latest LibPRI)
523 * Added ability to send and receive ETSI Explicit Call Transfer (ECT) messages
524 to eliminate tromboned calls. A tromboned call goes out an interface and comes
525 back into the same interface. Tromboned calls happen because of call routing,
526 call deflection, call forwarding, and call transfer.
527 * Added the ability to send and receive ETSI Advice-Of-Charge messages.
528 * Added the ability to support call waiting calls. (The SETUP has no B channel
530 * Added Malicious Call ID (MCID) event to the AMI call event class.
531 * Added Message Waiting Indication (MWI) support for ISDN PTMP endpoints (phones).
533 Asterisk Manager Interface
534 --------------------------
535 * The Hangup action now accepts a Cause header which may be used to
536 set the channel's hangup cause.
537 * sslprivatekey option added to manager.conf and http.conf. Adds the ability
538 to specify a separate .pem file to hold a private key. By default sslcert
539 is used to hold both the public and private key.
540 * Options in manager.conf and http.conf with the 'ssl' prefix have been replaced
541 for options containing the 'tls' prefix. For example, 'sslenable' is now
542 'tlsenable'. This has been done in effort to keep ssl and tls options consistent
543 across all .conf files. All affected sample.conf files have been modified to
544 reflect this change. Previous options such as 'sslenable' still work,
545 but options with the 'tls' prefix are preferred.
546 * Added a MuteAudio AMI action for muting inbound and/or outbound audio
547 in a channel. (res_mutestream.so)
548 * The configuration file manager.conf now supports a channelvars option, which
549 specifies a list of channel variables to include in each channel-oriented
551 * The redirect command now has new parameters ExtraContext, ExtraExtension,
552 and ExtraPriority to allow redirecting the second channel to a different
553 location than the first.
554 * Added new event "JabberStatus" in the Jabber module to monitor buddies
556 * Added a "MixMonitorMute" AMI action for muting inbound and/or outbound audio
557 in a MixMonitor recording.
558 * The 'iax2 show peers' output is now similar to the expected output of
560 * Added Advice-Of-Charge events (AOC-S, AOC-D, and AOC-E) in the new
562 * Added Advice-Of-Charge manager action, AOCMessage, for generating AOC-D and
563 AOC-E messages on a channel.
564 * A DBGetComplete event now follows a DBGetResponse, to make the DBGet action
565 conform more closely to similar events.
566 * Added a new eventfilter option per user to allow whitelisting and blacklisting
568 * Added optional parkinglot variable for park command.
569 * Added ConnectedLineNum and ConnectedLineName headers to the output of Status
572 Channel Event Logging
573 ---------------------
574 * A new interface, CEL, is introduced here. CEL logs single events, much like
575 the AMI, but it differs from the AMI in that it logs to db backends much
576 like CDR does; is based on the event subsystem introduced by Russell, and
577 can share in all its benefits; allows multiple backends to operate like CDR;
578 is specialized to event data that would be of concern to billing sytems,
579 like CDR. Backends for logging and accounting calls have been produced,
580 but a new CDR backend is still in development.
584 * 'linkedid' and 'peeraccount' are new CDR fields available to CDR aficionados.
585 linkedid is based on uniqueID, but spreads to other channels as transfers, dials,
586 etc are performed. Thus the pieces of CDR can be grouped into multilegged sets.
587 * Multiple files and formats can now be specified in cdr_custom.conf.
588 * cdr_syslog has been added which allows CDRs to be written directly to syslog.
589 See configs/cdr_syslog.conf.sample for more information.
590 * A 'sequence' field has been added to CDRs which can be combined with
591 linkedid or uniqueid to uniquely identify a CDR.
592 * Handling of billsec and duration field has changed. If your table definition
593 specifies those fields as float,double or similar they will now be logged with
594 microsecond accuracy instead of a whole integer.
596 Calendaring for Asterisk
597 ------------------------
598 * A new set of modules were added supporing calendar integration with Asterisk.
599 Dialplan functions for reading from and writing to calendars are included,
600 as well as the ability to execute dialplan logic upon calendar event notifications.
601 iCalendar, CalDAV, and Exchange Server calendars (via res_calendar_exchange for
602 Exchange Server 2003 with no write or attendee support, and res_calendar_ews for
603 Exchange Server 2007+ with full write and attendee support) are supported (Exchange
604 2003 support does not support forms-based authentication).
606 Call Completion Supplementary Services for Asterisk
607 ---------------------------------------------------
608 * Call completion support has been added for SIP, DAHDI/ISDN, and DAHDI/analog.
609 DAHDI/ISDN supports call completion for the following switch types:
610 EuroIsdn(ETSI) for PTP and PTMP modes, and Qsig.
611 See doc/CCSS_architecture.pdf and doc/tex/ccss.tex(asterisk.pdf) for details.
613 Multicast RTP Support
614 ---------------------
615 * A new RTP engine and channel driver have been added which supports Multicast RTP.
616 The channel driver can be used with the Page application to perform multicast RTP
617 paging. The dial string format is: MulticastRTP/<type>/<destination>/<control address>
618 Type can be either basic or linksys.
619 Destination is the IP address and port for the RTP packets.
620 Control address is specific to the linksys type and is used for sending the control
621 packets unique to them.
623 Security Events Framework
624 -------------------------
625 * Asterisk has a new C API for reporting security events. The module res_security_log
626 sends these events to the "security" logger level. Currently, AMI is the only
627 Asterisk component that reports security events. However, SIP support will be
628 coming soon. For more information on the security events framework, see the
629 "Security Events" chapter of the included documentation - doc/tex/asterisk.pdf.
633 * A technology independent fax frontend (res_fax) has been added to Asterisk.
634 * A spandsp based fax backend (res_fax_spandsp) has been added.
635 * The app_fax module has been deprecated in favor of the res_fax module and
636 the new res_fax_spandsp backend.
637 * The SendFAX and ReceiveFAX applications now send their log messages to a
638 'fax' logger level, instead of to the generic logger levels. To see these
639 messages, the system's logger.conf file will need to direct the 'fax' logger
640 level to one or more destinations; the logger.conf.sample file includes an
641 example of how to do this. Note that if the 'fax' logger level is *not*
642 directed to at least one destination, log messages generated by these
643 applications will be lost, and that if the 'fax' logger level is directed to
644 the console, the 'core set verbose' and 'core set debug' CLI commands will
645 have no effect on whether the messages appear on the console or not.
649 * The transmit_silence_during_record option in asterisk.conf.sample has been removed.
650 Now, in order to enable transmitting silence during record the transmit_silence
651 option should be used. transmit_silence_during_record remains a valid option, but
652 defaults to the behavior of the transmit_silence option.
653 * Addition of the Unit Test Framework API for managing registration and execution
654 of unit tests with the purpose of verifying the operation of C functions.
655 * SendText is now implemented in chan_gtalk and chan_jingle. It will simply send
656 XMPP text messages to the remote JID.
657 * Modules.conf has a new option - "require" - that marks a module as critical for
658 the execution of Asterisk.
659 If one of the required modules fail to load, Asterisk will exit with a return
661 * An 'X' option has been added to the asterisk application which enables #exec support.
662 This allows #exec to be used in asterisk.conf.
663 * jabber.conf supports a new option auth_policy that toggles auto user registration.
664 * A new lockconfdir option has been added to asterisk.conf to protect the
665 configuration directory (/etc/asterisk by default) during reloads.
666 * The parkeddynamic option has been added to features.conf to enable the creation
667 of dynamic parkinglots.
668 * chan_dahdi now supports reporting alarms over AMI either by channel or span via
669 the reportalarms config option.
670 * chan_dahdi supports dialing configuring and dialing by device file name.
671 DAHDI/span-name!local!1 will use /dev/dahdi/span-name/local/1 . Likewise
672 it may appear in chan_dahdi.conf as 'channel => span-name!local!1'.
673 * A new options for chan_dahdi.conf: 'ignore_failed_channels'. Boolean.
674 False by default. If set, chan_dahdi will ignore failed 'channel' entries.
675 Handy for the above name-based syntax as it does not depend on
676 initialization order.
677 * The Realtime dialplan switch now caches entries for 1 second. This provides a
678 significant increase in performance (about 3X) for installations using this switchtype.
679 * Distributed devicestate now supports the use of the XMPP protocol, in addition to
680 AIS. For more information, please see doc/distributed_devstate-XMPP.txt
681 * The addition of G.719 pass-through support.
682 * Added support for 16khz Speex audio. This can be enabled by using 'allow=speex16'
683 during device configuration.
684 * The UNISTIM channel driver (chan_unistim) has been updated to support devices that
685 have less than 3 lines on the LCD.
686 * Realtime now supports database failover. See the sample extconfig.conf for details.
687 * The addition of improved translation path building for wideband codecs. Sample
688 rate changes during translation are now avoided unless absolutely necessary.
689 * The addition of the res_stun_monitor module for monitoring and reacting to network
690 changes while behind a NAT.
694 * The 'core set debug' and 'core set verbose' commands, in previous versions, could
695 optionally accept a filename, to apply the setting only to the code generated from
696 that source file when Asterisk was built. However, there are some modules in Asterisk
697 that are composed of multiple source files, so this did not result in the behavior
698 that users expected. In this version, 'core set debug' and 'core set verbose'
699 can optionally accept *module* names instead (with or without the .so extension),
700 which applies the setting to the entire module specified, regardless of which source
701 files it was built from.
702 * New 'manager show settings' command showing the current settings loaded from
704 * Added 'all' keyword to the CLI command "channel request hangup" so that you can send
705 the channel hangup request to all channels.
706 * Added a "core reload" CLI command that executes a global reload of Asterisk.
708 ------------------------------------------------------------------------------
709 --- Functionality changes from Asterisk 1.6.1 to Asterisk 1.6.2 -------------
710 ------------------------------------------------------------------------------
714 * Added support for SUBSCRIBE/NOTIFY with dialog-info based call pickups.
715 Snom phones use this for call pickup of extensions that the phone is
717 * Added support for setting the domain in the URI for caller of an
718 outbound call by using the SIPFROMDOMAIN channel variable.
719 * Added a new configuration option "remotesecret" for authentication to
720 remote services. For backwards compatibility, "secret" still has the
721 same function as before, but now you can configure both a remote secret and a
722 local secret for mutual authentication.
723 * If the channel variable ATTENDED_TRANSFER_COMPLETE_SOUND is set,
724 the sound will be played to the target of an attended transfer
725 * Added two new configuration options, "qualifygap" and "qualifypeers", which allow
726 finer control over how many peers Asterisk will qualify and the gap between them
727 when all peers need to be qualified at the same time.
728 * Added a new 'ignoresdpversion' option to sip.conf. When this is enabled
729 (either globally or for a specific peer), chan_sip will treat any SDP data
730 it receives as new data and update the media stream accordingly. By
731 default, Asterisk will only modify the media stream if the SDP session
732 version received is different from the current SDP session version. This
733 option is required to interoperate with devices that have non-standard SDP
734 session version implementations (observed with Microsoft OCS). This option
735 is disabled by default.
736 * The parsing of register => lines in sip.conf has been modified to allow a port
737 to be present in the "user" portion. Please see the sip.conf.sample file for more
739 * Added support for subscribing to MWI on a remote server and making the status available
740 as a mailbox. Please see the sip.conf.sample file for more information.
741 * Added a function to remove SIP headers added in the dialplan before the
742 first INVITE is generated - SIPRemoveHeader()
743 * Channel variables set with setvar= in a device configuration is now
744 set both for inbound and outbound calls.
745 * Added support for ITU G.722.1 and G.722.1C (Siren7 and Siren14) media streams.
749 * Added immediate option to iax.conf
750 * Added forceencryption option to iax.conf
751 * Added Encryption and Trunk status to manager command "iaxpeers"
755 * The configuration file now holds separate sections for devices and lines.
756 Please have a look at configs/skinny.conf.sample and change your skinny.conf
761 * chan_dahdi now supports MFC/R2 signaling when Asterisk is compiled with
762 support for LibOpenR2. http://www.libopenr2.org/
763 * The UK option waitfordialtone has been added for use with BT analog
765 * Added a 'faxbuffers' configuration option to chan_dahdi.conf. This option
766 is used in conjunction with the 'faxdetect' configuration option. When
767 'faxbuffers' is used and fax tones are detected, the channel will dynamically
768 switch to the configured faxbuffers policy. For example, to use 6 buffers
769 and a 'full' buffer policy for a fax transmission, add:
771 The faxbuffers configuration will be in affect until the call is torn down.
772 * Added service message support for 4ESS/5ESS switches.
776 * For DAHDI channels, the CHANNEL() dialplan function now
777 supports changing the channel's buffer policy (for the current
778 call only), using this syntax:
780 exten => s,n,Set(CHANNEL(buffers)=6,full)
782 This would change the channel to the 'full' buffer policy and
783 6 (six) buffers. Possible options for this setting are the same
784 as those in chan_dahdi.conf.
785 * Added a new dialplan function, CURLOPT, which permits setting various
786 options that may be useful with the CURL dialplan function, such as
787 cookies, proxies, connection timeouts, passwords, etc.
788 * Permit the syntax and synopsis fields of the corresponding dialplan
789 functions to be individually set from func_odbc.conf.
790 * Added debugging CLI functions to func_odbc, 'odbc read' and 'odbc write'.
791 * func_odbc now may specify an insert query to execute, when the write query
792 affects 0 rows (usually indicating that no such row exists).
793 * Added a new dialplan function, LISTFILTER, which permits removing elements
794 from a set list, by name. Uses the same general syntax as the existing CUT
795 and FIELDQTY dialplan functions, which also manage lists.
796 * Added REALTIME_FIELD and REALTIME_HASH, which should aid users in better
797 obtaining realtime data from the dialplan.
798 * Added LOCAL_PEEK, which allows access to variables in any stack frame within
799 a subroutine when using the GoSub() and Return() applications.
800 * Added AUDIOHOOK_INHERIT. For information on its use, please see the output
801 of "core show function AUDIOHOOK_INHERIT" from the CLI
802 * Added AES_ENCRYPT. For information on its use, please see the output
803 of "core show function AES_ENCRYPT" from the CLI
804 * Added AES_DECRYPT. For information on its use, please see the output
805 of "core show function AES_DECRYPT" from the CLI
806 * func_odbc now supports database transactions across multiple queries.
810 * Scheduled meetme conferences may now have their end times extended by
812 * app_authenticate now gives the ability to select a prompt other than
814 * app_directory now pays attention to the searchcontexts setting in
815 voicemail.conf and will look through all contexts, if no context is
816 specified in the initial argument.
817 * A new application, Originate, has been introduced, that allows asynchronous
818 call origination from the dialplan.
819 * Voicemail now permits setting the emailsubject and emailbody per mailbox,
820 in addition to the setting in the "general" context.
821 * Added ConfBridge dialplan application which does conference bridges without
822 DAHDI. For information on its use, please see the output of
823 "core show application ConfBridge" from the CLI.
827 * The Asterisk CLI has a new command, "channel redirect", which is similar in
828 operation to the AMI Redirect action.
829 * extensions.conf now allows you to use keyword "same" to define an extension
830 without actually specifying an extension. It uses exactly the same pattern
831 as previously used on the last "exten" line. For example:
832 exten => 123,1,NoOp(something)
833 same => n,SomethingElse()
834 * musiconhold.conf classes of type 'files' can now use relative directory paths,
835 which are interpreted as relative to the astvarlibdir setting in asterisk.conf.
836 * All deprecated CLI commands are removed from the sourcecode. They are now handled
837 by the new clialiases module. See cli_aliases.conf.sample file.
838 * Times within timespecs are now accurate down to the minute. This is a change
839 from historical Asterisk, which only provided timespecs rounded to the nearest
840 even (read: evenly divisible by 2) minute mark.
841 * The realtime switch now supports an option flag, 'p', which disables searches for
843 * In addition to a time range and date range, timespecs now accept a 5th optional
844 argument, timezone. This allows you to perform time checks on alternate
845 timezones, especially if those daylight savings time ranges vary from your
846 machine's native timezone. See GotoIfTime, ExecIfTime, IFTIME(), and timed
848 * The contrib/scripts/ directory now has a script called sip_nat_settings that will
849 give you the correct output for an asterisk box behind nat. It will give you the
850 externhost and localnet settings.
851 * The Asterisk core now supports ITU G.722.1 and G.722.1C media streams, and
852 can connect calls in passthrough mode, as well as record and play back files.
853 * Successful and unsuccessful call pickup can now be alerted through sounds, by
854 using pickupsound and pickupfailsound in features.conf.
855 * ASTVARRUNDIR is now set to $(localstatedir)/run/asterisk by default.
856 This means the asterisk pid file will now be in /var/run/asterisk/asterisk.pid on LINUX
857 instead of the /var/run/asterisk.pid where it used to be. This will make
858 installs as non-root easier to manage.
863 * The cdr.conf file must exist and be correctly programmed in order for CDR records to
864 be written; they will no longer be explicitly written.
866 Asterisk Manager Interface
867 --------------------------
868 * When using the AMI over HTTP, you can now include a 'SuppressEvents' header (with
869 a non-empty value) in your request. If you do this, any pending AMI events will
870 *not* be included in the response to your request as they would normally, but
871 will be left in the event queue for the next request you make to retrieve. For
872 some applications, this will allow you to guarantee that you will only see
873 events in responses to 'WaitEvent' actions, and can better know when to expect them.
874 To know whether the Asterisk server supports this header or not, your client can
875 inspect the first response back from the server to see if it includes this header:
877 Pragma: SuppressEvents
879 If this is included, the server supports event suppression.
881 * Added 4 new Actions to list skinny device(s) and line(s)
887 LDAP Schema File Additions
888 --------------------------
889 * Added AsteriskDialplan, AsteriskAccount and AsteriskMailbox objectClasses
890 to allow standalone dialplan, account and mailbox entries (STRUCTURAL)
892 - AstAccountLanguage, AstAccountTransport, AstAccountPromiscRedir,
893 - AstAccountAccountCode, AstAccountSetVar, AstAccountAllowOverlap,
894 - AstAccountVideoSupport, AstAccountIgnoreSDPVersion
895 * Removed redundant IPaddr (there's already IPAddress)
896 - Gives more configuration Flags for SIP-Users available (tested)
897 - Allows to create Asterisk Attributes in defined Asterisk ObjectClasses
898 without extensibleObject (which really should be the last resort); gives
899 also additional possibilities for LDAP-filter
901 ------------------------------------------------------------------------------
902 --- Functionality changes from Asterisk 1.6.0 to Asterisk 1.6.1 -------------
903 ------------------------------------------------------------------------------
905 Device State Handling
906 ---------------------
907 * The event infrastructure in Asterisk got another big update to help support
908 distributed events. It currently supports distributed device state and
909 distributed Voicemail MWI (Message Waiting Indication). A new module has
910 been merged, res_ais, which facilitates communicating events between servers.
911 It uses the SAForum AIS (Service Availability Forum Application Interface
912 Specification) CLM (Cluster Management) and EVT (Event) services to maintain
913 a cluster of Asterisk servers, and to share events between them. For more
914 information on setting this up, see doc/distributed_devstate.txt.
918 * Added a new dialplan function, AST_CONFIG(), which allows you to access
919 variables from an Asterisk configuration file.
920 * The JACK_HOOK function now has a c() option to supply a custom client name.
921 * Added two new dialplan functions from libspeex for audio gain control and
922 denoise, AGC() and DENOISE(). Both functions can be applied to the tx and
923 rx directions of a channel from the dialplan.
924 * The SMDI_MSG_RETRIEVE function now has the ability to search for SMDI messages
925 based on other parameters. The default is still to search based on the
926 forwarding station ID. However, there are new options that allow you to search
927 based on the message desk terminal ID, or the message desk number.
928 * TIMEOUT() has been modified to be accurate down to the millisecond.
929 * ENUM*() functions now include the following new options:
930 - 'u' returns the full URI and does not strip off the URI-scheme.
931 - 's' triggers ISN specific rewriting
932 - 'i' looks for branches into an Infrastructure ENUM tree
933 - 'd' for a direct DNS lookup without any flipping of digits.
934 * TXCIDNAME() has a new zone-suffix parameter (which defaults to 'e164.arpa')
935 * CHANNEL() now has options for the maximum, minimum, and standard or normal
936 deviation of jitter, rtt, and loss for a call using chan_sip.
938 DAHDI channel driver (chan_dahdi) Changes
939 ----------------------------------------
940 * Channels can now be configured using named sections in chan_dahdi.conf, just
941 like other channel drivers, including the use of templates.
942 * The default for pridialplan has changed from 'national' to 'unknown'.
946 * It is now possible to specify a pattern match as a hint. Once a phone subscribes
947 to something that matches the pattern a hint will be created using the contents
948 and variables evaluated.
949 * Dialplan matching has been extended to allow an extension to return to the
950 PBX core to wait for more digits. This is done by using the new dialplan
951 application called "Incomplete". This will permit a whole new level of
952 extension control, by giving the administrator more control over early
953 matches employing one of the short-circuit pattern match operators. Note
954 that custom applications can trigger this same behavior by returning the
955 special value AST_PBX_INCOMPLETE.
959 * Directory now permits both first and last names to be matched at the same
960 time. In addition, the number of digits to enter of the name can be set in
961 the arguments to Directory; previously, you could enter only 3, regardless
962 of how many names are in your company. For large companies, this should be
964 * Voicemail now permits a mailbox setting to wrap around from first to last
965 messages, if the "messagewrap" option is set to a true value.
966 * Voicemail now permits an external script to be run, for password validation.
967 The script should output "VALID" or "INVALID" on stdout, depending upon the
968 wish to validate or invalidate the password given. Arguments are:
969 "mailbox" "context" "oldpass" "newpass". See the sample voicemail.conf for
971 * Dial has a new option: F(context^extension^pri), which permits a callee to
972 continue in the dialplan, at the specified label, if the caller hangs up.
973 * ChanSpy and ExtenSpy have a new option, 's' which suppresses speaking the
974 technology name (e.g. SIP, IAX, etc) of the channel being spied on.
975 * The Jack application now has a c() option to supply a custom client name.
976 * Chanspy has a new option, 'B', which can be used to "barge" on a call. This is
977 like the pre-existing whisper mode, except that the spy can also talk to the
978 participant on the bridged channel as well.
979 * Chanspy has a new option, 'n', which will allow for the spied-on party's name
980 to be spoken instead of the channel name or number. For more information on the
981 use of this option, issue the command "core show application ChanSpy" from the
983 * Chanspy has a new option, 'd', which allows the spy to use DTMF to swap between
984 spy modes. Use of this feature overrides the typical use of numeric DTMF. In other
985 words, if using the 'd' option, it is not possible to enter a number to append to
986 the first argument to Chanspy(). Pressing 4 will change to spy mode, pressing 5 will
987 change to whisper mode, and pressing 6 will change to barge mode.
988 * ExternalIVR now takes several options that affect the way it performs, as
989 well as having several new commands. Please see doc/externalivr.txt for the
990 complete documentation.
991 * Added ability to communicate over a TCP socket instead of forking a child process for the
992 ExternalIVR application.
993 * ChanIsAvail has a new option, 'a', which will return all available channels instead
994 of just the first one if you give the function more then one channel to check.
995 * PrivacyManager now takes an option where you can specify a context where the
996 given number will be matched. This way you have more control over who is allowed
997 and it stops the people who blindly enter 10 digits.
998 * ForkCDR has new options: 'a' updates the answer time on the new CDR; 'A' locks
999 answer times, disposition, on orig CDR against updates; 'D' Copies the disposition
1000 from the orig CDR to the new CDR after reset; 'e' sets the 'end' time on the
1001 original CDR; 'R' prevents the new CDR from being reset; 's(var=val)' adds/changes
1002 the 'var' variable on the original CDR; 'T' forces ast_cdr_end(), ast_cdr_answer(),
1003 obey the LOCKED flag on cdr's in the chain, and also the ast_cdr_setvar() func.
1004 * The Dial() application no longer copies the language used by the caller to the callee's
1005 channel. If you desire for the caller's channel's language to be used for file playback
1006 to the callee, then the file specified may be prepended with "${CHANNEL(language)}/" .
1007 * SendImage() no longer hangs up the channel on error; instead, it sets the
1008 status variable SENDIMAGESTATUS to one of 'SUCCESS', 'FAILURE', or
1009 'UNSUPPORTED'. This change makes SendImage() more consistent with other
1011 * Park has a new option, 's', which silences the announcement of the parking space number.
1012 * A non-numeric, zero, or negative timeout specified to Dial() will now be interpreted as
1013 invalid input and will be assumed to mean that no timeout is desired.
1017 * Added DNS manager support to registrations for peers referencing peer entries.
1018 DNS manager runs in the background which allows DNS lookups to be run asynchronously
1019 as well as periodically updating the IP address. These properties allow for
1020 better performance as well as recovery in the event of an IP change.
1021 * Performance improvements via using hash tables (astobj2) and doubly-linked lists to improve
1022 load/reload of large numbers of peers/users by ~40x (for large lists of peers).
1023 These changes also provide performance improvements for call setup and tear down.
1024 * Added ability to specify registration expiry time on a per registration basis in
1026 * Added support for T140 RED - redundancy in T.140 to prevent text loss due to
1028 * Added t38pt_usertpsource option. See sip.conf.sample for details.
1029 * Added SIPnotify AMI command, for sending arbitrary SIP notify commands.
1030 * 'sip show peers' and 'sip show users' display their entries sorted in
1031 alphabetical order, as opposed to the order they were in, in the config
1033 * Videosupport now supports an additional option, "always", which always sets
1034 up video RTP ports, even on clients that don't support it. This helps with
1035 callfiles and certain transfers to ensure that if two video phones are
1036 connected, they will always share video feeds.
1040 * Existing DNS manager lookups extended to check for SRV records.
1041 * IAX2 encryption support has been improved to support periodic key rotation
1042 within a call for enhanced security. The option "keyrotate" has been
1043 provided to disable this functionality to preserve backwards compatibility
1044 with older versions of IAX2 that do not support key rotation.
1048 * New CLI command, "data get <path> [<search> [<filter>]]" which retrieves the
1049 data tree based on the given <path>.
1050 * New CLI command "data show providers" that will display all the registered
1052 * New CLI command, "config reload <file.conf>" which reloads any module that
1053 references that particular configuration file. Also added "config list"
1054 which shows which configuration files are in use.
1055 * New CLI commands, "pri show version" and "ss7 show version" that will
1056 display which version of libpri and libss7 are being used, respectively.
1057 A new API call was added so trunk will now have to be compiled against
1058 a versions of libpri and libss7 that have them or it will not know that
1059 these libraries exist.
1060 * The commands "core show globals", "core set global" and "core set chanvar" has
1061 been deprecated in favor of the more semanticly correct "dialplan show globals",
1062 "dialplan set chanvar" and "dialplan set global".
1063 * New CLI command "dialplan show chanvar" to list all variables associated
1064 with a given channel.
1068 * Addresses managed by DNS manager now can check to see if there is a DNS
1069 SRV record for a given domain and will use that hostname/port if present.
1071 AMI - The manager (TCP/TLS/HTTP)
1072 --------------------------------
1073 * The Status command now takes an optional list of variables to display
1074 along with channel status.
1075 * The QueueEntry event now also includes the channel's uniqueid
1079 * res_odbc no longer has a limit of 1023 total possible unshared connections,
1080 as some people were running into this limit. This limit has been increased
1085 * The TRANSFER queue log entry now includes the the caller's original
1086 position in the transferred-from queue.
1087 * A new configuration option, "timeoutpriority" has been added. Please see the section labeled
1088 "QUEUE TIMING OPTIONS" in configs/queues.conf.sample for a detailed explanation of the option
1089 as well as an explanation about timeout options in general
1090 * Added a new option - C - for forcing the "answered elsewhere" flag on
1091 cancellation of calls in to members of the queue. This is to avoid the
1092 call to a member of a queue having the call listed as a "missed call".
1096 * Several (ODBC, Postgres, MySQL, SQLite) realtime drivers have been given
1097 adaptive capabilities. What this means in practical terms is that if your
1098 realtime table lacks critical fields, Asterisk will now emit warnings to
1099 that effect. Also, some of the realtime drivers have the ability (if
1100 configured) to automatically add those columns to the table with the
1101 correct type and length.
1105 * The channel variable ATTENDED_TRANSFER_COMPLETE_SOUND can now be set using
1106 the 'setvar' option to cause a given audio file to be played upon completion
1107 of an attended transfer. Currently it works for DAHDI, IAX2, SIP, and
1108 Skinny channels only.
1109 * You can now compile Asterisk against the Hoard Memory Allocator, see doc/hoard.txt
1110 for more information.
1111 * Config file variables may now be appended to, by using the '+=' append
1112 operator. This is most helpful when working with long SQL queries in
1113 func_odbc.conf, as the queries no longer need to be specified on a single
1115 * CDR config file, cdr.conf, has an added option, "initiatedseconds",
1116 which will add a second to the billsec when the ending
1117 time is set, if the number in the microseconds field of the end time is
1118 greater than the number of microseconds in the answer time. This allows
1119 users to count the 'initiated' seconds in their billing records.
1121 ------------------------------------------------------------------------------
1122 --- Functionality changes from Asterisk 1.4.X to Asterisk 1.6.0 -------------
1123 ------------------------------------------------------------------------------
1125 AMI - The manager (TCP/TLS/HTTP)
1126 --------------------------------
1127 * Manager has undergone a lot of changes, all of them documented
1128 in doc/manager_1_1.txt
1129 * Manager version has changed to 1.1
1130 * Added a new action 'CoreShowChannels' to list currently defined channels
1131 and some information about them.
1132 * Added a new action 'SIPshowregistry' to list SIP registrations.
1133 * Added TLS support for the manager interface and HTTP server
1134 * Added the URI redirect option for the built-in HTTP server
1135 * The output of CallerID in Manager events is now more consistent.
1136 CallerIDNum is used for number and CallerIDName for name.
1137 * Enable https support for builtin web server.
1138 See configs/http.conf.sample for details.
1139 * Added a new action, GetConfigJSON, which can return the contents of an
1140 Asterisk configuration file in JSON format. This is intended to help
1141 improve the performance of AJAX applications using the manager interface
1143 * SIP and IAX manager events now use "ChannelType" in all cases where we
1144 indicate channel driver. Previously, we used a mixture of "Channel"
1145 and "ChannelDriver" headers.
1146 * Added a "Bridge" action which allows you to bridge any two channels that
1147 are currently active on the system.
1148 * Added a "ListAllVoicemailUsers" action that allows you to get a list of all
1149 the voicemail users setup.
1150 * Added 'DBDel' and 'DBDelTree' manager commands.
1151 * cdr_manager now reports events via the "cdr" level, separating it from
1152 the very verbose "call" level.
1153 * Manager users are now stored in memory. If you change the manager account
1154 list (delete or add accounts) you need to reload manager.
1155 * Added Masquerade manager event for when a masquerade happens between
1157 * Added "manager reload" command for the CLI
1158 * Lots of commands that only provided information are now allowed under the
1159 Reporting privilege, instead of only under Call or System.
1160 * The IAX* commands now require either System or Reporting privilege, to
1161 mirror the privileges of the SIP* commands.
1162 * Added ability to retrieve list of categories in a config file.
1163 * Added ability to retrieve the content of a particular category.
1164 * Added ability to empty a context.
1165 * Created new action to create a new file.
1166 * Updated delete action to allow deletion by line number with respect to category.
1167 * Added new action insert to add new variable to category at specified line.
1168 * Updated action newcat to allow new category to be inserted in file above another
1170 * Added new event "JitterBufStats" in the IAX2 channel
1171 * Originate now requires the Originate privilege and, if you want to call out
1172 to a subshell, it requires the System privilege, as well. This was done to
1173 enhance manager security.
1174 * Originate now accepts codec settings with "Codecs: alaw, ulaw, h264"
1175 * New command: Atxfer. See doc/manager_1_1.txt for more details or
1176 manager show command Atxfer from the CLI
1177 * New command: IAXregistry. See doc/manager_1_1.txt for more details or
1178 manager show command IAXregistry from the CLI
1182 * Added the DEVICE_STATE() dialplan function which allows retrieving any device
1183 state in the dialplan, as well as creating custom device states that are
1184 controllable from the dialplan.
1185 * Extend CALLERID() function with "pres" and "ton" parameters to
1186 fetch string representation of calling number presentation indicator
1187 and numeric representation of type of calling number value.
1188 * MailboxExists converted to dialplan function
1189 * A new option to Dial() for telling IP phones not to count the call
1190 as "missed" when dial times out and cancels.
1191 * Added LOCK(), TRYLOCK(), and UNLOCK(), which provide a single level dialplan
1192 mutex. No deadlocks are possible, as LOCK() only allows a single lock to be
1193 held for any given channel. Also, locks are automatically freed when a
1195 * Added HINT() dialplan function that allows retrieving hint information.
1196 Hints are mappings between extensions and devices for the sake of
1197 determining the state of an extension. This function can retrieve the list
1198 of devices or the name associated with a hint.
1199 * Added EXTENSION_STATE() dialplan function which allows retrieving the state
1201 * Added SYSINFO() dialplan function which allows retrieval of system information
1202 * Added a new dialplan function, DIALPLAN_EXISTS(), which allows you to check for
1203 the existence of a dialplan target.
1204 * Added two new dialplan functions, TOUPPER and TOLOWER, which convert a string to
1205 upper and lower case, respectively.
1206 * When bridging, Asterisk sets the BRIDGEPVTCALLID to the channel drivers unique
1207 ID for the call (not the Asterisk call ID or unique ID), provided that the
1208 channel driver supports this. For SIP, you get the SIP call-ID for the
1209 bridged channel which you can store in the CDR with a custom field.
1213 * Added CLI permissions, config file: cli_permissions.conf
1214 default is to allow all commands for every local user/group.
1215 Also this new feature added three new CLI commands:
1216 - cli check permissions {<username>|@<groupname>|<username>@<groupname>} [<command>]
1217 - cli reload permissions
1218 - cli show permissions
1219 * New CLI command "core show hint" (usage: core show hint <exten>)
1220 * New CLI command "core show settings"
1221 * Added 'core show channels count' CLI command.
1222 * Added the ability to set the core debug and verbose values on a per-file basis.
1223 * Added 'queue pause member' and 'queue unpause member' CLI commands
1224 * Ability to set process limits ("ulimit") without restarting Asterisk
1225 * Enhanced "agi debug" to print the channel name as a prefix to the debug
1226 output to make debugging on busy systems much easier.
1227 * New CLI commands "dialplan set extenpatternmatching true/false"
1228 * New CLI command: "core set chanvar" to set a channel variable from the CLI.
1229 * Added an easy way to execute Asterisk CLI commands at startup. Any commands
1230 listed in the startup_commands section of cli.conf will get executed.
1231 * Added a CLI command, "devstate change", which allows you to set custom device
1232 states from the func_devstate module that provides the DEVICE_STATE() function
1233 and handling of the "Custom:" devices.
1234 * New CLI command: "sip show sched" which shows all ast_sched entries for sip,
1235 sorted into the different possible callbacks, with the number of entries
1236 currently scheduled for each. Gives you a feel for how busy the sip channel
1238 * Added 'skinny show lines verbose' CLI command. This will show the subs for every channel.
1239 * Cleanup another bunch of CLI commands. Now all modules follow the same schema.
1240 (Done by lmadsen, junky and mvanbaak during the devcon 2008)
1244 * Added a new 'faxdetect=yes|no' configuration option to sip.conf. When this
1245 option is enabled, Asterisk will watch for a CNG tone in the incoming audio
1246 for a received call. If it is detected, the channel will jump to the
1247 'fax' extension in the dialplan.
1248 * The default SIP useragent= identifier now includes the Asterisk version
1249 * A new option, match_auth_username in sip.conf changes the matching of incoming requests.
1250 If set, and the incoming request carries authentication info,
1251 the username to match in the users list is taken from the Digest header
1252 rather than from the From: field. This feature is considered experimental.
1253 * The "musiconhold" and "musicclass" settings in sip.conf are now removed,
1254 since they where replaced by "mohsuggest" and "mohinterpret" in version 1.4
1255 * The "localmask" setting was removed in version 1.2 and the reminder about it
1256 being removed is now also removed.
1257 * A new option "busylevel" for setting a level of calls where asterisk reports
1258 a device as busy, to separate it from call-limit. This value is also added
1259 to the SIP_PEER dialplan function.
1260 * A new realtime family called "sipregs" is now supported to store SIP registration
1261 data. If this family is defined, "sippeers" will be used for configuration and
1262 "sipregs" for registrations. If it's not defined, "sippeers" will be used for
1263 registration data, as before.
1264 * The SIPPEER function have new options for port address, call and pickup groups
1265 * Added support for T.140 realtime text in SIP/RTP
1266 * The "checkmwi" option has been removed from sip.conf, as it is no longer
1267 required due to the restructuring of how MWI is handled. See the descriptions
1268 in this file of the "pollmailboxes" and "pollfreq" options to voicemail.conf
1269 for more information.
1270 * Added rtpdest option to CHANNEL() dialplan function.
1271 * Added SIPREFERRINGCONTEXT and SIPREFERREDBYHDR variables which are set when a transfer takes place.
1272 * SIP now adds a header to the CANCEL if the call was answered by another phone
1273 in the same dial command, or if the new c option in dial() is used.
1274 * The new default is that 100 Trying is not sent on REGISTER attempts as the RFC specifically
1275 states it is not needed. For phones, however, that do require it the "registertrying" option
1276 has been added so it can be enabled.
1277 * A new option called "callcounter" (global/peer/user level) enables call counters needed
1278 for better status reports needed for queues and SIP subscriptions. (Call-Limit was previously
1279 used to enable this functionality).
1280 * New settings for timer T1 and timer B on a global level or per device. This makes it
1281 possible to force timeout faster on non-responsive SIP servers. These settings are
1282 considered advanced, so don't use them unless you have a problem.
1283 * Added a dial string option to be able to set the To: header in an INVITE to any
1285 * Added a new global and per-peer option, qualifyfreq, which allows you to configure
1286 the qualify frequency.
1287 * Added SIP Session Timers support (RFC 4028). This prevents stuck SIP sessions that
1288 were not properly torn down due to network or endpoint failures during an established
1290 * Added experimental TCP and TLS support for SIP. See doc/siptls.txt and
1291 configs/sip.conf.sample for more information on how it is used.
1292 * Added a new configuration option "authfailureevents" that enables manager events when
1293 a peer can't authenticate properly.
1294 * Added DNS manager support to registrations for peers not referencing a peer entry.
1298 * Added the trunkmaxsize configuration option to chan_iax2.
1299 * Added the srvlookup option to iax.conf
1300 * Added support for OSP. The token is set and retrieved through the CHANNEL()
1303 XMPP Google Talk/Jingle changes
1304 -------------------------------
1305 * Added the bindaddr option to gtalk.conf.
1309 * Added skinny show device, skinny show line, and skinny show settings CLI commands.
1310 * Proper codec support in chan_skinny.
1311 * Added settings for IP and Ethernet QoS requests
1315 * Added separate settings for media QoS in mgcp.conf
1317 Console Channel Driver changes
1318 ------------------------------
1319 * Added experimental support for video send & receive to chan_oss.
1320 This requires SDL and ffmpeg/avcodec, plus Video4Linux or X11 to act as
1323 Phone channel changes (chan_phone)
1324 ----------------------------------
1325 * Added G729 passthrough support to chan_phone for Sigma Designs boards.
1327 H.323 channel Changes
1328 ---------------------
1329 * H323 remote hold notification support added (by NOTIFY message
1330 and/or H.450 supplementary service)
1332 Local channel changes
1333 ---------------------
1334 * The device state functionality in the Local channel driver has been updated
1335 to indicate INUSE or NOT_INUSE when a Local channel is being used as opposed
1336 to just UNKNOWN if the extension exists.
1337 * Added jitterbuffer support for chan_local. This allows you to use the
1338 generic jitterbuffer on incoming calls going to Asterisk applications.
1339 For example, this would allow you to use a jitterbuffer for an incoming
1340 SIP call to Voicemail by putting a Local channel in the middle. This
1341 feature is enabled by using the 'j' option in the Dial string to the Local
1342 channel in conjunction with the existing 'n' option for local channels.
1343 * A 'b' option has been added which causes chan_local to return the actual channel
1344 that is behind it when queried. This is useful for transfer scenarios as the
1345 actual channel will be transferred, not the Local channel.
1347 Agent channel changes
1348 ----------------------
1349 * The ackcall and endcall options are now supplemented with options acceptdtmf
1350 and enddtmf. These allow for the DTMF keypress to be configurable. The options
1351 default to their old hard-coded values ('#' and '*' respectively) so this should
1352 not break any existing agent installations.
1354 DAHDI channel driver (chan_dahdi) Changes
1355 ----------------------------------------
1356 * SS7 support (via libss7 library)
1357 * In India, some carriers transmit CID via dtmf. Some code has been added
1358 that will handle some situations. The cidstart=polarity_IN choice has been added for
1359 those carriers that transmit CID via dtmf after a polarity change.
1360 * CID matching information is now shown when doing 'dialplan show'.
1361 * Added dahdi show version CLI command.
1362 * Added setvar support to chan_dahdi.conf channel entries.
1363 * Added two new options: mwimonitor and mwimonitornotify. These options allow
1364 you to enable MWI monitoring on FXO lines. When the MWI state changes,
1365 the script specified in the mwimonitornotify option is executed. An internal
1366 event indicating the new state of the mailbox is also generated, so that
1367 the normal MWI facilities in Asterisk work as usual.
1368 * Added signalling type 'auto', which attempts to use the same signalling type
1369 for a channel as configured in DAHDI. This is primarily designed for analog
1370 ports, but will also work for digital ports that are configured for FXS or FXO
1371 signalling types. This mode is also the default now, so if your chan_dahdi.conf
1372 does not specify signalling for a channel (which is unlikely as the sample
1373 configuration file has always recommended specifying it for every channel) then
1374 the 'auto' mode will be used for that channel if possible.
1375 * Added a 'dahdi set dnd' command to allow CLI control of the Do-Not-Disturb
1376 state for a channel; also ensured that the DNDState Manager event is
1377 emitted no matter how the DND state is set or cleared.
1381 * Added a new channel driver, chan_unistim. See doc/unistim.txt and
1382 configs/unistim.conf.sample for details. This new channel driver allows
1383 you to use Nortel i2002, i2004, and i2050 phones with Asterisk.
1384 * Added a new channel driver, chan_console, which uses portaudio as a cross
1385 platform audio interface. It was written as a channel driver that would
1386 work with Mac CoreAudio, but portaudio supports a number of other audio
1387 interfaces, as well. Note that this channel driver requires v19 or higher
1388 of portaudio; older versions have a different API.
1392 * Added the ability to specify arguments to the Dial application when using
1393 the DUNDi switch in the dialplan.
1394 * Added the ability to set weights for responses dynamically. This can be
1395 done using a global variable or a dialplan function. Using the SHELL()
1396 function would allow you to have an external script set the weight for
1398 * Added two new dialplan functions, DUNDIQUERY and DUNDIRESULT. These
1399 functions will allow you to initiate a DUNDi query from the dialplan,
1400 find out how many results there are, and access each one.
1401 * Added the ability to specifiy a port for a dundi peer.
1405 * Added two new dialplan functions, ENUMQUERY and ENUMRESULT. These
1406 functions will allow you to initiate an ENUM lookup from the dialplan,
1407 and Asterisk will cache the results. ENUMRESULT can be used to access
1408 the results without doing multiple DNS queries.
1412 * Added the ability to customize which sound files are used for some of the
1413 prompts within the Voicemail application by changing them in voicemail.conf
1414 * Added the ability for the "voicemail show users" CLI command to show users
1415 configured by the dynamic realtime configuration method.
1416 * MWI (Message Waiting Indication) handling has been significantly
1417 restructured internally to Asterisk. It is now totally event based
1418 instead of polling based. The voicemail application will notify other
1419 modules that have subscribed to MWI events when something in the mailbox
1421 This also means that if any other entity outside of Asterisk is changing
1422 the contents of mailboxes, then the voicemail application still needs to
1423 poll for changes. Examples of situations that would require this option
1424 are web interfaces to voicemail or an email client in the case of using
1425 IMAP storage. So, two new options have been added to voicemail.conf
1426 to account for this: "pollmailboxes" and "pollfreq". See the sample
1427 configuration file for details.
1428 * Added "tw" language support
1429 * Added support for storage of greetings using an IMAP server
1430 * Added ability to customize forward, reverse, stop, and pause keys for message playback
1431 * SMDI is now enabled in voicemail using the smdienable option.
1432 * A "lockmode" option has been added to asterisk.conf to configure the file
1433 locking method used for voicemail, and potentially other things in the
1434 future. The default is the old behavior, lockfile. However, there is a
1435 new method, "flock", that uses a different method for situations where the
1436 lockfile will not work, such as on SMB/CIFS mounts.
1437 * Added the ability to backup deleted messages, to ease recovery in the case
1438 that a user accidentally deletes a message, and discovers that they need it.
1439 * Reworked the SMDI interface in Asterisk. The new way to access SMDI information
1440 is through the new functions, SMDI_MSG_RETRIEVE() and SMDI_MSG(). The file
1441 smdi.conf can now be configured with options to map SMDI station IDs to Asterisk
1442 voicemail boxes. The SMDI interface can also poll for MWI changes when some
1443 outside entity is modifying the state of the mailbox (such as IMAP storage or
1444 a web interface of some kind).
1445 * Added the support for marking messages as "urgent." There are two methods to accomplish
1446 this. One is to pass the 'U' option to VoiceMail(). Another way to mark a message as urgent
1447 is to specify "review=yes" in voicemail.conf. Doing this will cause allow the user to mark
1448 the message as urgent after he has recorded a voicemail by following the voice instructions.
1449 When listening to voicemails using VoiceMailMain urgent messages will be presented before other
1454 * Added the general option 'shared_lastcall' so that member's wrapuptime may be
1455 used across multiple queues.
1456 * Added QUEUE_VARIABLES function to set queue variables added setqueuevar and
1457 setqueueentryvar options for each queue, see queues.conf.sample for details.
1458 * Added keepstats option to queues.conf which will keep queue
1459 statistics during a reload.
1460 * setinterfacevar option in queues.conf also now sets a variable
1461 called MEMBERNAME which contains the member's name.
1462 * Added 'Strategy' field to manager event QueueParams which represents
1463 the queue strategy in use.
1464 * Added option to run macro when a queue member is connected to a caller,
1465 see queues.conf.sample for details.
1466 * app_queue now has a 'loose' option which is almost exactly like 'strict' except it
1467 does not count paused queue members as unavailable.
1468 * Added min-announce-frequency option to queues.conf which allows you to control the
1469 minimum amount of time between queue announcements for use when the caller's queue
1470 position changes frequently.
1471 * Added additional information to EXITWITHTIMEOUT and EXITWITHKEY events in the
1473 * Added ability for non-realtime queues to have realtime members
1474 * Added the "linear" strategy to queues.
1475 * Added the "wrandom" strategy to queues.
1476 * Added new channel variable QUEUE_MIN_PENALTY
1477 * QUEUE_MAX_PENALTY and QUEUE_MIN_PENALTY may be adjusted in mid-call by defining
1478 rules in queuerules.conf. See configs/queuerules.conf.sample for details
1479 * Added a new parameter for member definition, called state_interface. This may be
1480 used so that a member may be called via one interface but have a different interface's
1481 device state reported.
1482 * Added new CLI and Manager commands relating to reloading queues. From the CLI, see
1483 "queue reload", "queue reset stats". Also see "manager show command QueueReload" and
1484 "manager show command QueueReset."
1485 * New configuration option: randomperiodicannounce. If a list of periodic announcements is
1486 specified by the periodic-announce option, then one will be chosen randomly when it is time
1487 to play a periodic announcment
1488 * New configuration options: announce-position now takes two more values in addition to "yes" and
1489 "no." Two new options, "limit" and "more," are allowed. These are tied to another option,
1490 announce-position-limit. By setting announce-position to "limit" callers will only have their
1491 position announced if their position is less than what is specified by announce-position-limit.
1492 If announce-position is set to "more" then callers beyond the position specified by announce-position-limit
1493 will be told that their are more than announce-position-limit callers waiting.
1494 * Two new queue log events have been added. An ADDMEMBER event will be logged
1495 when a realtime queue member is added and a REMOVEMEMBER event will be logged
1496 when a realtime queue member is removed. Since there is no calling channel associated
1497 with these events, the string "REALTIME" is placed where the channel's unique id
1498 is typically placed.
1499 * The configuration method for the "joinempty" and "leavewhenempty" options has
1500 changed to a comma-separated list of methods of determining member availability
1501 instead of vague terms such as "yes," "loose," "no," and "strict." These old four
1502 values are still accepted for backwards-compatibility, though.
1503 * The average talktime is now calculated on queues. This information is reported via the
1504 CLI commands "queue show" and "queues show"; through the AMI events AgentComplete, QueueSummary,
1505 and QueueParams; and through the channelvariable QUEUETALKTIME if setinterfacevar=yes is set for
1510 * The 'o' option to provide an optimization has been removed and its functionality
1511 has been enabled by default.
1512 * When a conference is created, the UNIQUEID of the channel that caused it to be
1513 created is stored. Then, every channel that joins the conference will have the
1514 MEETMEUNIQUEID channel variable set with this ID. This can be used to relate
1515 callers that come and go from long standing conferences.
1516 * Added a new application, MeetMeChannelAdmin, which is similar to MeetMeAdmin,
1517 except it does operations on a channel by name, instead of number in a conference.
1518 This is a very useful feature in combination with the 'X' option to ChanSpy.
1519 * Added 'C' option to Meetme which causes a caller to continue in the dialplan
1521 * Added new RealTime functionality to provide support for scheduled conferencing.
1522 This includes optional messages to the caller if they attempt to join before
1523 the schedule start time, or to allow the caller to join the conference early.
1524 Also included is optional support for limiting the number of callers per
1525 RealTime conference.
1526 * Added the S() and L() options to the MeetMe application. These are pretty
1527 much identical to the S() and L() options to Dial(). They let you set
1528 timeouts for the conference, as well as have warning sounds played to
1529 let the caller know how much time is left, and when it is running out.
1530 * Added the ability to do "meetme concise" with the "meetme" CLI command.
1531 This extends the concise capabilities of this CLI command to include
1532 listing all conferences, instead of an addition to the other sub commands
1533 for the "meetme" command.
1534 * Added the ability to specify the music on hold class used to play into the
1535 conference when there is only one member and the M option is used.
1536 * Added MEETME_INFO dialplan function which provides a way to query
1537 various properties of a Meetme conference.
1538 * Added new admin features: *81: Roll call, *82: eject all, *83: mute all,
1539 and *84: record in-conf
1541 Other Dialplan Application Changes
1542 ----------------------------------
1543 * Argument support for Gosub application
1544 * From the to-do lists: straighten out the app timeout args:
1545 Wait() app now really does 0.3 seconds- was truncating arg to an int.
1546 WaitExten() same as Wait().
1547 Congestion() - Now takes floating pt. argument.
1548 Busy() - now takes floating pt. argument.
1549 Read() - timeout now can be floating pt.
1550 WaitForRing() now takes floating pt timeout arg.
1551 SpeechBackground() -- clarified in the docstrings that the timeout is an integer seconds.
1552 * Added 's' option to Page application.
1553 * Added an optional timeout argument to the Page application.
1554 * Added 'E', 'V', and 'P' commands to ExternalIVR.
1555 * Added 'o' and 'X' options to Chanspy.
1556 * Added a new dialplan application, Bridge, which allows you to bridge the
1557 calling channel to any other active channel on the system.
1558 * Added the ability to specify a music on hold class to play instead of ringing
1559 for the SLATrunk application.
1560 * The Read application no longer exits the dialplan on error. Instead, it sets
1561 READSTATUS to ERROR, which you can catch and handle separately.
1562 * Added 'm' option to Directory, which lists out names, 8 at a time, instead
1563 of asking for verification of each name, one at a time.
1564 * Privacy() no longer uses privacy.conf, as all options are specifyable as
1565 direct options to the app.
1566 * AMD() has a new "maximum word length" option. "show application AMD" from the CLI
1568 * GotoIfTime() now may branch based on a "false" condition, like other Goto-related applications
1569 * The ChannelRedirect application no longer exits the dialplan if the given channel
1570 does not exist. It will now set the CHANNELREDIRECT_STATUS variable to SUCCESS upon success
1571 or NOCHANNEL if the given channel was not found.
1572 * The silencethreshold setting that was previously configurable in multiple
1573 applications is now settable globally via dsp.conf.
1575 Music On Hold Changes
1576 ---------------------
1577 * A new option, "digit", has been added for music on hold classes in
1578 musiconhold.conf. If this is set for a music on hold class, a caller
1579 listening to music on hold can press this digit to switch to listening
1580 to this music on hold class.
1581 * Support for realtime music on hold has been added.
1582 * In conjunction with the realtime music on hold, a general section has
1583 been added to musiconhold.conf, its sole variable is cachertclasses. If this
1584 is set, then music on hold classes found in realtime will be cached in memory.
1588 * AEL upgraded to use the Gosub with Arguments instead
1589 of Macro application, to hopefully reduce the problems
1590 seen with the artificially low stack ceiling that
1591 Macro bumps into. Macros can only call other Macros
1592 to a depth of 7. Tests run using gosub, show depths
1593 limited only by virtual memory. A small test demonstrated
1594 recursive call depths of 100,000 without problems.
1595 -- in addition to this, all apps that allowed a macro
1596 to be called, as in Dial, queues, etc, are now allowing
1597 a gosub call in similar fashion.
1598 * AEL now generates LOCAL(argname) declarations when it
1599 Set()'s the each arg name to the value of ${ARG1}, ${ARG2),
1600 etc. That makes the arguments local in scope. The user
1601 can define their own local variables in macros, now,
1602 by saying "local myvar=someval;" or using Set() in this
1603 fashion: Set(LOCAL(myvar)=someval); ("local" is now
1605 * utils/conf2ael introduced. Will convert an extensions.conf
1606 file into extensions.ael. Very crude and unfinished, but
1607 will be improved as time goes by. Should be useful for a
1608 first pass at conversion.
1609 * aelparse will now read extensions.conf to see if a referenced
1610 macro or context is there before issueing a warning.
1611 * AEL parser sets a local channel variable ~~EXTEN~~, to
1612 preserve the value of ${EXTEN} thru switch statements.
1613 * New operator in $[...] expressions: the ~~ operator serves
1614 as a concatenation operator. AT THE MOMENT, it is really only
1615 necessary and useful in AEL, especially in if() expressions.
1616 Operation: ${a} ~~ ${b| with force both a and b to strings, strip
1617 any enclosing double-quotes, and evaluate to the value of a
1618 concatenated with the value of b. For example if a is set to
1619 "xyz" and b has the value "abc", then ${a} ~~ ${b| would
1620 evaluate to xyzabc .
1623 Call Features (res_features) Changes
1624 ------------------------------------
1625 * Added the parkedcalltransfers option to features.conf
1626 * Added parkedcallparking option to control one touch parking w/ parking
1628 * Added parkedcallhangup option to control disconnect feature w/ parking
1630 * Added parkedcallrecording option to control one-touch record w/ parking
1632 * Added parkedcallparking, parkedcallhangup, parkedcallrecording, and
1633 parkedcalltransfers option support for multiple parking lots.
1634 * Added BRIDGE_FEATURES variable to set available features for a channel
1635 * The built-in method for doing attended transfers has been updated to
1636 include some new options that allow you to have the transferee sent
1637 back to the person that did the transfer if the transfer is not successful.
1638 See the options "atxferdropcall", "atxferloopdelay", and "atxfercallbackretries"
1639 in features.conf.sample.
1640 * Added support for configuring named groups of custom call features in
1641 features.conf. This means that features can be written a single time, and
1642 then mapped into groups of features for different key mappings or easier
1644 * Updated the ParkedCall application to allow you to not specify a parking
1645 extension. If you don't specify a parking space to pick up, it will grab
1646 the first one available.
1647 * Added cli command 'features reload' to reload call features from features.conf
1648 * Moved into core asterisk binary.
1649 * Changed the default setting for featuredigittimeout to 2000 ms from 500 ms.
1650 * Added the ability for custom parking lots to be configured with their own
1651 parking extension with the parkext option.
1653 Language Support Changes
1654 ------------------------
1655 * Brazilian Portuguese (pt-BR) in VM, and say.c was added
1656 * Added support for the Hungarian language for saying numbers, dates, and times.
1660 * Added SPEECH commands for speech recognition. A complete listing can be found
1662 * If app_stack is loaded, GOSUB is a native AGI command that may be used to
1663 invoke subroutines in the dialplan. Note that calling EXEC with Gosub
1664 does not behave as expected; the native command needs to be used, instead.
1665 * Added the ability to perform SRV lookups on fast AGI calls. To use this
1666 feature, simply use hagi: instead of agi: as the protocol portion
1667 of the URI parameter to the AGI function call in your dial plan. Also note
1668 that specifying a port number in the AGI URI will disable SRV lookups,
1669 even if you use the hagi: protocol.
1670 * No longer support MSG_OOB flag on HANGUP.
1674 * Added rotatestrategy option to logger.conf, along with two new options:
1675 "timestamp" which will use the time to name the logger files instead of
1676 sequence number; and "rotate", which rotates the names of the log files,
1677 similar to the way syslog rotates files.
1678 * Added exec_after_rotate option to logger.conf, which allows a system
1679 command to be run after rotation. This is primarily useful with
1680 rotatestrategy=rotate, to allow a limit on the number of log files kept
1681 and to ensure that the oldest log file gets deleted.
1682 * Added realtime support for the queue log
1686 * The cdr_manager module has a [mappings] feature, like cdr_custom,
1687 to add fields to the manager event from the CDR variables.
1688 * Added cdr_adaptive_odbc, a new module that adapts to the structure of your
1689 backend database CDR table. Specifically, additional, non-standard
1690 columns are supported, merely by setting the corresponding CDR variable in
1691 your dialplan. In addition, you may alias any column to another name (for
1692 example, if you want the 'src' CDR variable to be column 'ANI' in the DB,
1693 simply "alias src => ANI" in the configuration file). Records may be
1694 posted to more than one backend, simply by specifying multiple categories
1695 in the configuration file. And finally, you may filter which CDRs get
1696 posted to each backend, by specifying a filter (which the record must
1697 match) for the particular category. Filters are additive (meaning all
1698 rules must match to post that CDR).
1699 * The Postgres CDR module now supports some features of the cdr_adaptive_odbc
1700 module. Specifically, you may add additional columns into the table and
1701 they will be set, if you set the corresponding CDR variable name. Also,
1702 if you omit columns in your database table, they will be silently skipped
1703 (but a record will still be inserted, based on what columns remain). Note
1704 that the other two features from cdr_adaptive_odbc (alias and filter) are
1705 not currently supported.
1706 * The ResetCDR application now has an 'e' option that re-enables a CDR if it
1707 has been disabled using the NoCDR application.
1709 Miscellaneous New Modules
1710 -------------------------
1711 * Added a new CDR module, cdr_sqlite3_custom.
1712 * Added a new realtime configuration module, res_config_sqlite
1713 * Added a new codec translation module, codec_resample, which re-samples
1714 signed linear audio between 8 kHz and 16 kHz to help support wideband
1716 * Added a new module, res_phoneprov, which allows auto-provisioning of phones
1717 based on configuration templates that use Asterisk dialplan function and
1718 variable substitution. It should be possible to create phone profiles and
1719 templates that work for the majority of phones provisioned over http. It
1720 is currently only intended to provision a single user account per phone.
1721 An example profile and set of templates for Polycom phones is provided.
1722 NOTE: Polycom firmware is not included, but should be placed in
1723 AST_DATA_DIR/phoneprov/configs to match up with the included templates.
1724 * Added a new module, app_jack, which provides interfaces to JACK, the Jack
1725 Audio Connection Kit (http://www.jackaudio.org/). Two interfaces are
1726 provided; there is a JACK() application, and a JACK_HOOK() function. Both
1727 interfaces create an input and output JACK port. The application makes
1728 these ports the endpoint of the call. The audio coming from the channel
1729 goes out the output port and whatever comes back in on the input port is
1730 what gets sent to the channel. The JACK_HOOK() function turns on a JACK
1731 audiohook on the channel. This lets you run the audio coming from a
1732 channel through JACK, and whatever comes back in is what gets forwarded
1733 on as the channel's audio. This is very useful for building custom
1734 vocoders or doing recording or analysis of the channel's audio in another
1736 * Added a new module, res_config_curl, which permits using a HTTP POST url
1737 to retrieve, create, update, and delete realtime information from a remote
1738 web server. Note that this module requires func_curl.so to be loaded for
1739 backend functionality.
1740 * Added a new module, res_config_ldap, which permits the use of an LDAP
1741 server for realtime data access.
1742 * Added support for writing and running your dialplan in lua using the pbx_lua
1743 module. See configs/extensions.lua.sample for examples of how to do this.
1747 * Ability to use libcap to set high ToS bits when non-root
1748 on Linux. If configure is unable to find libcap then you
1749 can use --with-cap to specify the path.
1750 * Added maxfiles option to options section of asterisk.conf which allows you to specify
1751 what Asterisk should set as the maximum number of open files when it loads.
1752 * Added the jittertargetextra configuration option.
1753 * Added support for setting the CoS for VLAN traffic (802.1p). See the sample
1754 configuration files for the IP channel drivers. The new option is "cos".
1755 This information is also documented in doc/qos.tex, or the IP Quality of Service
1756 section of asterisk.pdf.
1757 * When originating a call using AMI or pbx_spool that fails the reason for failure
1758 will now be available in the failed extension using the REASON dialplan variable.
1759 * Added support for reading the TOUCH_MONITOR_PREFIX channel variable.
1760 It allows you to configure a prefix for auto-monitor recordings.
1761 * A new extension pattern matching algorithm, based on a trie, is introduced
1762 here, that could noticeably speed up mid-sized to large dialplans.
1763 It is NOT used by default, as duplicating the behaviour of the old pattern
1764 matcher is still under development. A config file option, in extensions.conf,
1765 in the [general] section, called "extenpatternmatchingnew", is by default
1766 set to false; setting that to true will force the use of the new algorithm.
1767 Also, the cli commands "dialplan set extenpatternmatchingnew true/false" can
1768 be used to switch the algorithms at run time.
1769 * A new option when starting a remote asterisk (rasterisk, asterisk -r) for
1770 specifying which socket to use to connect to the running Asterisk daemon
1772 * Performance enhancements to the sched facility, which is used in
1773 the channel drivers, etc. Added hashtabs and doubly-linked lists
1774 to speed up deletion; start at the beginning or end of list to
1776 * Added Doubly-linked lists after the fashion of linkedlists.h. They are in
1777 dlinkedlists.h. Doubly-linked lists feature fast deletion times.
1778 Added regression tests to the tests/ dir, also.
1779 * Added a refcount trace feature to astobj2 for those trying to balance
1780 object creation, deletion; work, play; space and time. See the
1781 notes in astobj2.h. Also, see utils/refcounter as well, as a
1782 quick way to find unbalanced refcounts in what could be a sea
1783 of objects that were balanced.
1784 * Added logging to 'make update' command. See update.log
1785 * Added strictrtp option to rtp.conf. If enabled this will drop RTP packets that
1786 do not come from the remote party.
1787 * Added the 'n' option to the SpeechBackground application to tell it to not
1788 answer the channel if it has not already been answered.
1789 * Added a compiler flag, CHANNEL_TRACE, which permits channel tracing to be
1790 turned on, via the CHANNEL(trace) dialplan function. Could be useful for
1792 * iLBC source code no longer included (see UPGRADE.txt for details)
1793 * If compiled with DETECT_DEADLOCKS enabled and if you have glibc, then if
1794 deadlock is detected, a backtrace of the stack which led to the lock calls
1795 will be output to the CLI.
1796 * If compiled with DEBUG_THREADS enabled and if you have glibc, then issuing
1797 the "core show locks" CLI command will give lock information output as well
1798 as a backtrace of the stack which led to the lock calls.
1799 * users.conf now sports an optional alternateexts property, which permits
1800 allocation of additional extensions which will reach the specified user.
1801 * A new option for the configure script, --enable-internal-poll, has been added
1802 for use with systems which may have a buggy implementation of the poll system
1803 call. If you notice odd behavior such as the CLI being unresponsive on remote
1804 consoles, you may want to try using this option. This option is enabled by default
1805 on Darwin systems since it is known that the Darwin poll() implementation has
1809 --------------------
1810 * In addition to timing from DAHDI, there is a new timing module called
1811 res_timing_timerfd. In order to use this, you must be running Linux with
1812 a kernel version 2.6.25 or newer as well as glibc 2.8 or newer. The configure
1813 script will be able to tell if you have the requirements. From menuselect, select
1814 res_timing_timerfd from the Resource Modules menu.
