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.
19 Asterisk Manager Interface
20 --------------------------
21 * PeerStatus now includes Address and Port.
22 * Added Hold events for when the remote party puts the call on and off hold
23 for chan_dahdi ISDN channels.
24 * Added new action MeetmeListRooms to list active conferences (shows same
25 data as "meetme list" at the CLI).
26 * DAHDIShowChannels, SIPshowpeer, SIPpeers, and IAXpeers now contains a
27 Description field that is set by 'description' in the channel configuration
31 --------------------------
32 * The HTTP Server can bind to IPv6 addresses.
35 --------------------------
36 * Busy tone patterns featuring 2 silence and 2 tone lengths can now be used
37 with busydetect. usage example: busypattern=200,200,200,600
40 --------------------------
41 * New 'gtalk show settings' command showing the current settings loaded from
43 * The 'logger reload' command now supports an optional argument, specifying an
44 alternate configuration file to use.
45 * 'dialplan add extension' command will now automatically create a context if
46 the specified context does not exist with a message indicated it did so.
47 * 'sip show peers', 'iax show peers', and 'dahdi show peers' now contains a
48 Description field which can be populated with 'description' in the channel
49 configuration files (sip.conf, iax2.conf, and chan_dahdi.conf).
52 --------------------------
53 * The filter option in cdr_adaptive_odbc now supports negating the argument,
54 thus allowing records which do NOT match the specified filter.
57 --------------------------
58 * Ability to define custom SILK formats in codecs.conf.
59 * Addition of speex32 audio format with translation.
62 --------------------------
63 * New highly optimized and customizable ConfBridge application capable of
64 mixing audio at sample rates ranging from 8khz-96khz.
65 * CONFBRIDGE dialplan function capable of creating dynamic ConfBridge user
66 and bridge profiles on a channel.
70 * Added ASTETCDIR, ASTMODDIR, ASTVARLIBDIR, ASTDBDIR, ASTKEYDIR, ASTDATADIR,
71 ASTAGIDIR, ASTSPOOLDIR, ASTRUNDIR, ASTLOGDIR which hold the equivalent
72 variables from asterisk.conf.
76 * Addition of the JITTERBUFFER dialplan function. This function allows
77 for jitterbuffering to occur on the read side of a channel. By using
78 this function conference applications such as ConfBridge and MeetMe can
79 have the rx streams jitterbuffered before conference mixing occurs.
80 * Added DB_KEYS, which lists the next set of keys in the Asterisk database
83 libpri channel driver (chan_dahdi) DAHDI changes
84 --------------------------
85 * Added moh_signaling option to specify what to do when the channel's bridged
86 peer puts the ISDN channel on hold.
87 * Added display_send and display_receive options to control how the display ie
88 is handled. To send display text from the dialplan use the SendText()
89 application when the option is enabled.
90 * Added mcid_send option to allow sending a MCID request on a span.
93 --------------------------
94 * Added setvar option to calendar.conf to allow setting channel variables on
95 notification channels.
96 * Added "calendar show types" CLI command to list registered calendar
100 --------------------------
101 * Added two new options, r and t with file name arguments to record
102 single direction (unmixed) audio recording separate from the bidirectional
103 (mixed) recording. The mixed file name argument is optional now as long
104 as at least one recording option is used.
107 --------------------------
108 * Added a new option, l, which will disable local call optimization for
109 channels involved with the FollowMe thread. Use this option to improve
110 compatability for a FollowMe call with certain dialplan apps, options, and
114 --------------------------
115 * cel_pgsql now supports the 'extra' column for data added using the
116 CELGenUserEvent() application.
118 ------------------------------------------------------------------------------
119 --- Functionality changes from Asterisk 1.6.2 to Asterisk 1.8 ----------------
120 ------------------------------------------------------------------------------
124 * Added preferred_codec_only option in sip.conf. This feature limits the joint
125 codecs sent in response to an INVITE to the single most preferred codec.
126 * Added SIP_CODEC_OUTBOUND dialplan variable which can be used to set the codec
127 to be used for the outgoing call. It must be one of the codecs configured
129 * Added tlsprivatekey option to sip.conf. This allows a separate .pem file
130 to be used for holding a private key. If tlsprivatekey is not specified,
131 tlscertfile is searched for both public and private key.
132 * Added tlsclientmethod option to sip.conf. This allows the protocol for
133 outbound client connections to be specified.
134 * The sendrpid parameter has been expanded to include the options
135 'rpid' and 'pai'. Setting sendrpid to 'rpid' will cause Remote-Party-ID
136 header to be sent (equivalent to setting sendrpid=yes) and setting
137 sendrpid to 'pai' will cause P-Asserted-Identity header to be sent.
138 * The 'ignoresdpversion' behavior has been made automatic when the SDP received
139 is in response to a T.38 re-INVITE that Asterisk initiated. In this situation,
140 since the call will fail if Asterisk does not process the incoming SDP, Asterisk
141 will accept the SDP even if the SDP version number is not properly incremented,
142 but will generate a warning in the log indicating that the SIP peer that sent
143 the SDP should have the 'ignoresdpversion' option set.
144 * The 'nat' option has now been been changed to have yes, no, force_rport, and
145 comedia as valid values. Setting it to yes forces RFC 3581 behavior and enables
146 symmetric RTP support. Setting it to no only enables RFC 3581 behavior if the
147 remote side requests it and disables symmetric RTP support. Setting it to
148 force_rport forces RFC 3581 behavior and disables symmetric RTP support.
149 Setting it to comedia enables RFC 3581 behavior if the remote side requests it
150 and enables symmetric RTP support.
151 * Slave SIP channels now set HASH(SIP_CAUSE,<slave-channel-name>) on each
152 response. This permits the master channel to know how each channel dialled
153 in a multi-channel setup resolved in an individual way.
154 * Added 'externtcpport' and 'externtlsport' options to allow custom port
155 configuration for the externip and externhost options when tcp or tls is used.
156 * Added support for message body (stored in content variable) to SIP NOTIFY message
157 accessible via AMI and CLI.
158 * Added 'media_address' configuration option which can be used to explicitly specify
159 the IP address to use in the SDP for media (audio, video, and text) streams.
160 * Added 'unsolicited_mailbox' configuration option which specifies the virtual mailbox
161 that the new/old count should be stored on if an unsolicited MWI NOTIFY message is
163 * Added 'use_q850_reason' configuration option for generating and parsing
164 if available Reason: Q.850;cause=<cause code> header. It is implemented
165 in some gateways for better passing PRI/SS7 cause codes via SIP.
166 * When dialing SIP peers, a new component may be added to the end of the dialstring
167 to indicate that a specific remote IP address or host should be used when dialing
168 the particular peer. The dialstring format is SIP/peer/exten/host_or_IP.
169 * SRTP SDES support for encrypting calls to/from Asterisk over SIP. The
170 ability to selectively force bridged channels to also be encrypted is also
171 implemented. Branching in the dialplan can be done based on whether or not
172 a channel has secure media and/or signaling.
173 * Added directmediapermit/directmediadeny to limit which peers can send direct media
175 * Added the 'snom_aoc_enabled' option to turn on support for sending Advice of
176 Charge messages to snom phones.
177 * Added support for G.719 media streams.
178 * Added support for 16khz signed linear media streams.
179 * SIP is now able to bind to and communicate with IPv6 addresses. In addition,
180 RTP has been outfitted with the same abilities.
181 * Added support for setting the Max-Forwards: header in SIP requests. Setting is
182 available in device configurations as well as in the dial plan.
183 * Addition of the 'subscribe_network_change' option for turning on and off
184 res_stun_monitor module support in chan_sip.
185 * Addition of the 'auth_options_requests' option for turning on and off
186 authentication for OPTIONS requests in chan_sip.
191 * Added rtsavesysname option into iax.conf to allow the systname to be saved
193 * Added the ability for chan_iax2 to inform the dialplan whether or not
194 encryption is being used. This interoperates with the SIP SRTP implementation
195 so that a secure SIP call can be bridged to a secure IAX call when the
196 dialplan requires bridged channels to be "secure".
197 * Addition of the 'subscribe_network_change' option for turning on and off
198 res_stun_monitor module support in chan_iax.
203 * Added ability to preset channel variables on indicated lines with the setvar
204 configuration option. Also, clearvars=all resets the list of variables back
206 * PacketCable NCS 1.0 support has been added for Docsis/Eurodocsis Networks.
207 See configs/res_pktccops.conf for more information.
209 XMPP Google Talk/Jingle changes
210 -------------------------------
211 * Added the externip option to gtalk.conf.
212 * Added the stunaddr option to gtalk.conf which allows for the automatic
213 retrieval of the external ip from a stun server.
217 * Added 'p' option to PickupChan() to allow for picking up channel by the first
218 match to a partial channel name.
219 * Added .m3u support for Mp3Player application.
220 * Added progress option to the app_dial D() option. When progress DTMF is
221 present, those values are sent immediately upon receiving a PROGRESS message
222 regardless if the call has been answered or not.
223 * Added functionality to the app_dial F() option to continue with execution
224 at the current location when no parameters are provided.
225 * Added the 'a' option to app_dial to answer the calling channel before any
226 announcements or macros are executed.
227 * Modified app_dial to set answertime when the called channel answers even if
228 the called channel hangs up during playback of an announcement.
229 * Modified app_dial 'r' option to support an additional parameter to play an
230 indication tone from indications.conf
231 * Added c() option to app_chanspy. This option allows custom DTMF to be set
232 to cycle through the next available channel. By default this is still '*'.
233 * Added x() option to app_chanspy. This option allows DTMF to be set to
234 exit the application.
235 * The Voicemail application has been improved to automatically ignore messages
236 that only contain silence.
237 * If you set maxmsg to 0 in voicemail.conf, Voicemail will consider the
238 associated mailbox(es) to be greetings-only.
239 * The ChanSpy application now has the 'S' option, which makes the application
240 automatically exit once it hits a point where no more channels are available
242 * The ChanSpy application also now has the 'E' option, which spies on a single
243 channel and exits when that channel hangs up.
244 * The MeetMe application now turns on the DENOISE() function by default, for
245 each participant. In our tests, this has significantly decreased background
246 noise (especially noisy data centers).
247 * Voicemail now permits storage of secrets in a separate file, located in the
248 spool directory of each individual user. The control for this is located in
249 the "passwordlocation" option in voicemail.conf. Please see the sample
250 configuration for more information.
251 * The ChanIsAvail application now exposes the returned cause code using a separate
252 variable, AVAILCAUSECODE, instead of overwriting the device state in AVAILSTATUS.
253 * Added 'd' option to app_followme. This option disables the "Please hold"
255 * Added 'y' option to app_record. This option enables a mode where any DTMF digit
256 received will terminate recording.
257 * Voicemail now supports per mailbox settings for folders when using IMAP storage.
258 Previously the folder could only be set per context, but has now been extended
259 using the imapfolder option.
260 * Voicemail now supports per mailbox settings for nextaftercmd and minsecs.
261 * Voicemail now allows the pager date format to be specified separately from the
263 * New applications JabberJoin, JabberLeave, and JabberSendGroup have been added
264 to allow joining, leaving, and sending text to group chats.
265 * MeetMe has a new option 'G' to play an announcement before joining a conference.
266 * Page has a new option 'A(x)' which will playback an announcement simultaneously
267 to all paged phones (and optionally excluding the caller's one using the new
268 option 'n') before the call is bridged.
269 * The 'f' option to Dial has been augmented to take an optional argument. If no
270 argument is provided, the 'f' option works as it always has. If an argument is
271 provided, then the connected party information of all outgoing channels created
272 during the Dial will be set to the argument passed to the 'f' option.
273 * Dial now inherits the GOSUB_RETVAL from the peer, when the U() option runs a
275 * The OSP lookup application adds in/outbound network ID, optional security,
276 number portability, QoS reporting, destination IP port, custom info and service
278 * Added new application VMSayName that will play the recorded name of the voicemail
279 user if it exists, otherwise will play the mailbox number.
280 * Added custom device states to ConfBridge bridges. Use 'confbridge:<name>' to
281 retrieve state for a particular bridge, where <name> is the conference name
282 * app_directory now allows exiting at any time using the operator or pound key.
283 * Voicemail now supports setting a locale per-mailbox.
284 * Two new applications are provided for declining counting phrases in multiple
285 languages. See the application notes for SayCountedNoun and SayCountedAdj for
287 * Voicemail now runs the externnotify script when pollmailboxes is activated and
289 * Voicemail now includes rdnis within msgXXXX.txt file.
290 * Added 'D' command to ExternalIVR full details in doc/externalivr.txt
291 * Added 'v' option to MeetMe to play voicemail greetings when a user joins/leaves
296 * SRVQUERY and SRVRESULT functions added. This can be used to query and iterate
297 over SRV records associated with a specific service. From the CLI, type
298 'core show function SRVQUERY' and 'core show function SRVRESULT' for more
299 details on how these may be used.
300 * PITCH_SHIFT dialplan function added. This function can be used to modify the
301 pitch of a channel's tx and rx audio streams.
302 * Added new dialplan functions CONNECTEDLINE and REDIRECTING which permits
303 setting various connected line and redirecting party information.
304 * CALLERID and CONNECTEDLINE dialplan functions have been extended to
305 support ISDN subaddressing.
306 * The CHANNEL() function now supports the "name" and "checkhangup" options.
307 * For DAHDI channels, the CHANNEL() dialplan function now allows
308 the dialplan to request changes in the configuration of the active
309 echo canceller on the channel (if any), for the current call only.
312 exten => s,n,Set(CHANNEL(echocan_mode)=off)
314 The possible values are:
316 on - normal mode (the echo canceller is actually reinitialized)
318 fax - FAX/data mode (NLP disabled if possible, otherwise completely
320 voice - voice mode (returns from FAX mode, reverting the changes that
321 were made when FAX mode was requested)
322 * Added new dialplan function MASTER_CHANNEL(), which permits retrieving
323 and setting variables on the channel which created the current channel.
324 Administrators should take care to avoid naming conflicts, when multiple
325 channels are dialled at once, especially when used with the Local channel
326 construct (which all could set variables on the master channel). Usage
327 of the HASH() dialplan function, with the key set to the name of the slave
328 channel, is one approach that will avoid conflicts.
329 * Added new dialplan function MUTEAUDIO() for muting inbound and/or outbound
331 * func_odbc now allows multiple row results to be retrieved without using
332 mode=multirow. If rowlimit is set, then additional rows may be retrieved
333 from the same query by using the name of the function which retrieved the
334 first row as an argument to ODBC_FETCH().
335 * Added JABBER_RECEIVE, which permits receiving XMPP messages from the
336 dialplan. This function returns the content of the received message.
337 * Added REPLACE, which searches a given variable name for a set of characters,
338 then either replaces them with a single character or deletes them.
339 * Added PASSTHRU, which literally passes the same argument back as its return
340 value. The intent is to be able to use a literal string argument to
341 functions that currently require a variable name as an argument.
342 * HASH-associated variables now can be inherited across channel creation, by
343 prefixing the name of the hash at assignment with the appropriate number of
344 underscores, just like variables.
345 * GROUP_MATCH_COUNT has been improved to allow regex matching on category
346 * CHANNEL(secure_bridge_signaling) and CHANNEL(secure_bridge_media) to set/get
347 whether or not channels that are bridged to the current channel will be
348 required to have secure signaling and/or media.
349 * CHANNEL(secure_signaling) and CHANNEL(secure_media) to get whether or not
350 the current channel has secure signaling and/or media.
351 * For DAHDI/ISDN channels, the CHANNEL() dialplan function now supports the
352 "no_media_path" option.
353 Returns "0" if there is a B channel associated with the call.
354 Returns "1" if no B channel is associated with the call. The call is either
355 on hold or is a call waiting call.
356 * Added option to dialplan function CDR(), the 'f' option
357 allows for high resolution times for billsec and duration fields.
358 * FILE() now supports line-mode and writing.
359 * Added FIELDNUM(), which returns the 1-based offset of a field in a list.
360 * FRAME_TRACE(), for tracking internal ast_frames on a channel.
364 * Added DYNAMIC_FEATURENAME which holds the last triggered dynamic feature.
365 * Added DYNAMIC_PEERNAME which holds the unique channel name on the other side
366 and is set when a dynamic feature is triggered.
367 * Added PARKINGLOT which can be used with parkeddynamic feature.conf option
368 to dynamically create a new parking lot matching the value this varible is
370 * Added PARKINGDYNAMIC which represents the template parkinglot defined in
371 features.conf that should be the base for dynamic parkinglots.
372 * Added PARKINGDYNCONTEXT which tells what context a newly created dynamic
373 parkinglot should have.
374 * Added PARKINGDYNPOS which holds what parking positions a dynamic parkinglot
379 * Added "ready" option to QUEUE_MEMBER counting to count free agents whose wrap-up
381 * Added 'R' option to app_queue. This option stops moh and indicates ringing
382 to the caller when an Agent's phone is ringing. This can be used to indicate
383 to the caller that their call is about to be picked up, which is nice when
384 one has been on hold for an extened period of time.
385 * A new config option, penaltymemberslimit, has been added to queues.conf.
386 When set this option will disregard penalty settings when a queue has too
388 * A new option, 'I' has been added to both app_queue and app_dial.
389 By setting this option, Asterisk will not update the caller with
390 connected line changes or redirecting party changes when they occur.
391 * A 'relative-peroidic-announce' option has been added to queues.conf. When
392 enabled, this option will cause periodic announce times to be calculated
393 from the end of announcements rather than from the beginning.
394 * The autopause option in queues.conf can be passed a new value, "all." The
395 result is that if a member becomes auto-paused, he will be paused in all
396 queues for which he is a member, not just the queue that failed to reach
398 * Added dialplan function QUEUE_EXISTS to check if a queue exists
399 * The queue logger now allows events to optionally propagate to a file,
400 even when realtime logging is turned on. Additionally, realtime logging
401 supports sending the event arguments to 5 individual fields, although it
402 will fallback to the previous data definition, if the new table layout is
405 mISDN channel driver (chan_misdn) changes
406 ----------------------------------------
407 * Added display_connected parameter to misdn.conf to put a display string
408 in the CONNECT message containing the connected name and/or number if
409 the presentation setting permits it.
410 * Added display_setup parameter to misdn.conf to put a display string
411 in the SETUP message containing the caller name and/or number if the
412 presentation setting permits it.
413 * Made misdn.conf parameters localdialplan and cpndialplan take a -1 to
414 indicate the dialplan settings are to be obtained from the asterisk
416 * Made misdn.conf parameter callerid accept the "name" <number> format
417 used by the rest of the system.
418 * Made use the nationalprefix and internationalprefix misdn.conf
419 parameters to prefix any received number from the ISDN link if that
420 number has the corresponding Type-Of-Number. NOTE: This includes
421 comparing the incoming call's dialed number against the MSN list.
422 * Added the following new parameters: unknownprefix, netspecificprefix,
423 subscriberprefix, and abbreviatedprefix in misdn.conf to prefix any
424 received number from the ISDN link if that number has the corresponding
426 * Added new dialplan application misdn_command which permits controlling
427 the CCBS/CCNR functionality.
428 * Added new dialplan function mISDN_CC which permits retrieval of various
429 values from an active call completion record.
430 * For PTP, you should manually send the COLR of the redirected-to party
431 for an incomming redirected call if the incoming call could experience
432 further redirects. Just set the REDIRECTING(to-num,i) = ${EXTEN} and
433 set the REDIRECTING(to-pres) to the COLR. A call has been redirected
434 if the REDIRECTING(from-num) is not empty.
435 * For outgoing PTP redirected calls, you now need to use the inhibit(i)
436 option on all of the REDIRECTING statements before dialing the
437 redirected-to party. You still have to set the REDIRECTING(to-xxx,i)
438 and the REDIRECTING(from-xxx,i) values. The PTP call will update the
439 redirecting-to presentation (COLR) when it becomes available.
440 * Added outgoing_colp parameter to misdn.conf to filter outgoing COLP
443 thirdparty mISDN enhancements
444 -----------------------------
445 mISDN has been modified by Digium, Inc. to greatly expand facility message
447 * Enhanced COLP support for call diversion and transfer.
450 The latest modified mISDN v1.1.x based version is available at:
451 http://svn.digium.com/svn/thirdparty/mISDN/trunk
452 http://svn.digium.com/svn/thirdparty/mISDNuser/trunk
454 Tagged versions of the modified mISDN code are available under:
455 http://svn.digium.com/svn/thirdparty/mISDN/tags
456 http://svn.digium.com/svn/thirdparty/mISDNuser/tags
458 libpri channel driver (chan_dahdi) DAHDI changes
459 -------------------------------------------
460 * The channel variable PRIREDIRECTREASON is now just a status variable
461 and it is also deprecated. Use the REDIRECTING(reason) dialplan function
462 to read and alter the reason.
463 * For Q.SIG and ETSI PRI/BRI-PTP, you should manually send the COLR of the
464 redirected-to party for an incomming redirected call if the incoming call
465 could experience further redirects. Just set the
466 REDIRECTING(to-num,i) = CALLERID(dnid) and set the REDIRECTING(to-pres)
467 to the COLR. A call has been redirected if the REDIRECTING(count) is not
469 * For outgoing Q.SIG and ETSI PRI/BRI-PTP redirected calls, you need to
470 use the inhibit(i) option on all of the REDIRECTING statements before
471 dialing the redirected-to party. You still have to set the
472 REDIRECTING(to-xxx,i) and the REDIRECTING(from-xxx,i) values. The call
473 will update the redirecting-to presentation (COLR) when it becomes available.
474 * Added the ability to ignore calls that are not in a Multiple Subscriber
475 Number (MSN) list for PTMP CPE interfaces.
476 * Added dynamic range compression support for dahdi channels. It is
477 configured via the rxdrc and txdrc parameters in chan_dahdi.conf.
478 * Added support for ISDN calling and called subaddress with partial support
479 for connected line subaddress.
480 * Added support for BRI PTMP NT mode. (Requires latest LibPRI.)
481 * Added handling of received HOLD/RETRIEVE messages and the optional ability
482 to transfer a held call on disconnect similar to an analog phone.
483 * Added CallRerouting/CallDeflection support for Q.SIG, ETSI PTP, ETSI PTMP.
484 Will reroute/deflect an outgoing call when receive the message.
485 Can use the DAHDISendCallreroutingFacility to send the message for the
487 * Added standard location to add options to chan_dahdi dialing:
488 Dial(DAHDI/g1[/extension[/options]])
491 R Reverse charging indication
492 * Added Reverse Charging Indication (Collect calls) send/receive option.
493 Send reverse charging in SETUP message with the chan_dahdi R dialing option.
494 Dial(DAHDI/g1/extension/R)
495 Access received reverse charge in SETUP message by: ${CHANNEL(reversecharge)}
496 (requires latest LibPRI)
497 * Added ability to send/receive keypad digits in the SETUP message.
498 Send keypad digits in SETUP message with the chan_dahdi K(<keypad_digits>)
499 dialing option. Dial(DAHDI/g1/[extension]/K(<keypad_digits>))
500 Access any received keypad digits in SETUP message by: ${CHANNEL(keypad_digits)}
501 (requires latest LibPRI)
502 * Added ability to send and receive ETSI Explicit Call Transfer (ECT) messages
503 to eliminate tromboned calls. A tromboned call goes out an interface and comes
504 back into the same interface. Tromboned calls happen because of call routing,
505 call deflection, call forwarding, and call transfer.
506 * Added the ability to send and receive ETSI Advice-Of-Charge messages.
507 * Added the ability to support call waiting calls. (The SETUP has no B channel
509 * Added Malicious Call ID (MCID) event to the AMI call event class.
510 * Added Message Waiting Indication (MWI) support for ISDN PTMP endpoints (phones).
512 Asterisk Manager Interface
513 --------------------------
514 * The Hangup action now accepts a Cause header which may be used to
515 set the channel's hangup cause.
516 * sslprivatekey option added to manager.conf and http.conf. Adds the ability
517 to specify a separate .pem file to hold a private key. By default sslcert
518 is used to hold both the public and private key.
519 * Options in manager.conf and http.conf with the 'ssl' prefix have been replaced
520 for options containing the 'tls' prefix. For example, 'sslenable' is now
521 'tlsenable'. This has been done in effort to keep ssl and tls options consistent
522 across all .conf files. All affected sample.conf files have been modified to
523 reflect this change. Previous options such as 'sslenable' still work,
524 but options with the 'tls' prefix are preferred.
525 * Added a MuteAudio AMI action for muting inbound and/or outbound audio
526 in a channel. (res_mutestream.so)
527 * The configuration file manager.conf now supports a channelvars option, which
528 specifies a list of channel variables to include in each channel-oriented
530 * The redirect command now has new parameters ExtraContext, ExtraExtension,
531 and ExtraPriority to allow redirecting the second channel to a different
532 location than the first.
533 * Added new event "JabberStatus" in the Jabber module to monitor buddies
535 * Added a "MixMonitorMute" AMI action for muting inbound and/or outbound audio
536 in a MixMonitor recording.
537 * The 'iax2 show peers' output is now similar to the expected output of
539 * Added Advice-Of-Charge events (AOC-S, AOC-D, and AOC-E) in the new
541 * Added Advice-Of-Charge manager action, AOCMessage, for generating AOC-D and
542 AOC-E messages on a channel.
543 * A DBGetComplete event now follows a DBGetResponse, to make the DBGet action
544 conform more closely to similar events.
545 * Added a new eventfilter option per user to allow whitelisting and blacklisting
547 * Added optional parkinglot variable for park command.
549 Channel Event Logging
550 ---------------------
551 * A new interface, CEL, is introduced here. CEL logs single events, much like
552 the AMI, but it differs from the AMI in that it logs to db backends much
553 like CDR does; is based on the event subsystem introduced by Russell, and
554 can share in all its benefits; allows multiple backends to operate like CDR;
555 is specialized to event data that would be of concern to billing sytems,
556 like CDR. Backends for logging and accounting calls have been produced,
557 but a new CDR backend is still in development.
561 * 'linkedid' and 'peeraccount' are new CDR fields available to CDR aficionados.
562 linkedid is based on uniqueID, but spreads to other channels as transfers, dials,
563 etc are performed. Thus the pieces of CDR can be grouped into multilegged sets.
564 * Multiple files and formats can now be specified in cdr_custom.conf.
565 * cdr_syslog has been added which allows CDRs to be written directly to syslog.
566 See configs/cdr_syslog.conf.sample for more information.
567 * A 'sequence' field has been added to CDRs which can be combined with
568 linkedid or uniqueid to uniquely identify a CDR.
569 * Handling of billsec and duration field has changed. If your table definition
570 specifies those fields as float,double or similar they will now be logged with
571 microsecond accuracy instead of a whole integer.
573 Calendaring for Asterisk
574 ------------------------
575 * A new set of modules were added supporing calendar integration with Asterisk.
576 Dialplan functions for reading from and writing to calendars are included,
577 as well as the ability to execute dialplan logic upon calendar event notifications.
578 iCalendar, CalDAV, and Exchange Server calendars (via res_calendar_exchange for
579 Exchange Server 2003 with no write or attendee support, and res_calendar_ews for
580 Exchange Server 2007+ with full write and attendee support) are supported (Exchange
581 2003 support does not support forms-based authentication).
583 Call Completion Supplementary Services for Asterisk
584 ---------------------------------------------------
585 * Call completion support has been added for SIP, DAHDI/ISDN, and DAHDI/analog.
586 DAHDI/ISDN supports call completion for the following switch types:
587 EuroIsdn(ETSI) for PTP and PTMP modes, and Qsig.
588 See doc/CCSS_architecture.pdf and doc/tex/ccss.tex(asterisk.pdf) for details.
590 Multicast RTP Support
591 ---------------------
592 * A new RTP engine and channel driver have been added which supports Multicast RTP.
593 The channel driver can be used with the Page application to perform multicast RTP
594 paging. The dial string format is: MulticastRTP/<type>/<destination>/<control address>
595 Type can be either basic or linksys.
596 Destination is the IP address and port for the RTP packets.
597 Control address is specific to the linksys type and is used for sending the control
598 packets unique to them.
600 Security Events Framework
601 -------------------------
602 * Asterisk has a new C API for reporting security events. The module res_security_log
603 sends these events to the "security" logger level. Currently, AMI is the only
604 Asterisk component that reports security events. However, SIP support will be
605 coming soon. For more information on the security events framework, see the
606 "Security Events" chapter of the included documentation - doc/tex/asterisk.pdf.
610 * A technology independent fax frontend (res_fax) has been added to Asterisk.
611 * A spandsp based fax backend (res_fax_spandsp) has been added.
612 * The app_fax module has been deprecated in favor of the res_fax module and
613 the new res_fax_spandsp backend.
614 * The SendFAX and ReceiveFAX applications now send their log messages to a
615 'fax' logger level, instead of to the generic logger levels. To see these
616 messages, the system's logger.conf file will need to direct the 'fax' logger
617 level to one or more destinations; the logger.conf.sample file includes an
618 example of how to do this. Note that if the 'fax' logger level is *not*
619 directed to at least one destination, log messages generated by these
620 applications will be lost, and that if the 'fax' logger level is directed to
621 the console, the 'core set verbose' and 'core set debug' CLI commands will
622 have no effect on whether the messages appear on the console or not.
626 * The transmit_silence_during_record option in asterisk.conf.sample has been removed.
627 Now, in order to enable transmitting silence during record the transmit_silence
628 option should be used. transmit_silence_during_record remains a valid option, but
629 defaults to the behavior of the transmit_silence option.
630 * Addition of the Unit Test Framework API for managing registration and execution
631 of unit tests with the purpose of verifying the operation of C functions.
632 * SendText is now implemented in chan_gtalk and chan_jingle. It will simply send
633 XMPP text messages to the remote JID.
634 * Modules.conf has a new option - "require" - that marks a module as critical for
635 the execution of Asterisk.
636 If one of the required modules fail to load, Asterisk will exit with a return
638 * An 'X' option has been added to the asterisk application which enables #exec support.
639 This allows #exec to be used in asterisk.conf.
640 * jabber.conf supports a new option auth_policy that toggles auto user registration.
641 * A new lockconfdir option has been added to asterisk.conf to protect the
642 configuration directory (/etc/asterisk by default) during reloads.
643 * The parkeddynamic option has been added to features.conf to enable the creation
644 of dynamic parkinglots.
645 * chan_dahdi now supports reporting alarms over AMI either by channel or span via
646 the reportalarms config option.
647 * chan_dahdi supports dialing configuring and dialing by device file name.
648 DAHDI/span-name!local!1 will use /dev/dahdi/span-name/local/1 . Likewise
649 it may appear in chan_dahdi.conf as 'channel => span-name!local!1'.
650 * A new options for chan_dahdi.conf: 'ignore_failed_channels'. Boolean.
651 False by default. If set, chan_dahdi will ignore failed 'channel' entries.
652 Handy for the above name-based syntax as it does not depend on
653 initialization order.
654 * The Realtime dialplan switch now caches entries for 1 second. This provides a
655 significant increase in performance (about 3X) for installations using this switchtype.
656 * Distributed devicestate now supports the use of the XMPP protocol, in addition to
657 AIS. For more information, please see doc/distributed_devstate-XMPP.txt
658 * The addition of G.719 pass-through support.
659 * Added support for 16khz Speex audio. This can be enabled by using 'allow=speex16'
660 during device configuration.
661 * The UNISTIM channel driver (chan_unistim) has been updated to support devices that
662 have less than 3 lines on the LCD.
663 * Realtime now supports database failover. See the sample extconfig.conf for details.
664 * The addition of improved translation path building for wideband codecs. Sample
665 rate changes during translation are now avoided unless absolutely necessary.
666 * The addition of the res_stun_monitor module for monitoring and reacting to network
667 changes while behind a NAT.
671 * The 'core set debug' and 'core set verbose' commands, in previous versions, could
672 optionally accept a filename, to apply the setting only to the code generated from
673 that source file when Asterisk was built. However, there are some modules in Asterisk
674 that are composed of multiple source files, so this did not result in the behavior
675 that users expected. In this version, 'core set debug' and 'core set verbose'
676 can optionally accept *module* names instead (with or without the .so extension),
677 which applies the setting to the entire module specified, regardless of which source
678 files it was built from.
679 * New 'manager show settings' command showing the current settings loaded from
681 * Added 'all' keyword to the CLI command "channel request hangup" so that you can send
682 the channel hangup request to all channels.
683 * Added a "core reload" CLI command that executes a global reload of Asterisk.
685 ------------------------------------------------------------------------------
686 --- Functionality changes from Asterisk 1.6.1 to Asterisk 1.6.2 -------------
687 ------------------------------------------------------------------------------
691 * Added support for SUBSCRIBE/NOTIFY with dialog-info based call pickups.
692 Snom phones use this for call pickup of extensions that the phone is
694 * Added support for setting the domain in the URI for caller of an
695 outbound call by using the SIPFROMDOMAIN channel variable.
696 * Added a new configuration option "remotesecret" for authentication to
697 remote services. For backwards compatibility, "secret" still has the
698 same function as before, but now you can configure both a remote secret and a
699 local secret for mutual authentication.
700 * If the channel variable ATTENDED_TRANSFER_COMPLETE_SOUND is set,
701 the sound will be played to the target of an attended transfer
702 * Added two new configuration options, "qualifygap" and "qualifypeers", which allow
703 finer control over how many peers Asterisk will qualify and the gap between them
704 when all peers need to be qualified at the same time.
705 * Added a new 'ignoresdpversion' option to sip.conf. When this is enabled
706 (either globally or for a specific peer), chan_sip will treat any SDP data
707 it receives as new data and update the media stream accordingly. By
708 default, Asterisk will only modify the media stream if the SDP session
709 version received is different from the current SDP session version. This
710 option is required to interoperate with devices that have non-standard SDP
711 session version implementations (observed with Microsoft OCS). This option
712 is disabled by default.
713 * The parsing of register => lines in sip.conf has been modified to allow a port
714 to be present in the "user" portion. Please see the sip.conf.sample file for more
716 * Added support for subscribing to MWI on a remote server and making the status available
717 as a mailbox. Please see the sip.conf.sample file for more information.
718 * Added a function to remove SIP headers added in the dialplan before the
719 first INVITE is generated - SIPRemoveHeader()
720 * Channel variables set with setvar= in a device configuration is now
721 set both for inbound and outbound calls.
722 * Added support for ITU G.722.1 and G.722.1C (Siren7 and Siren14) media streams.
726 * Added immediate option to iax.conf
727 * Added forceencryption option to iax.conf
728 * Added Encryption and Trunk status to manager command "iaxpeers"
732 * The configuration file now holds separate sections for devices and lines.
733 Please have a look at configs/skinny.conf.sample and change your skinny.conf
738 * chan_dahdi now supports MFC/R2 signaling when Asterisk is compiled with
739 support for LibOpenR2. http://www.libopenr2.org/
740 * The UK option waitfordialtone has been added for use with BT analog
742 * Added a 'faxbuffers' configuration option to chan_dahdi.conf. This option
743 is used in conjunction with the 'faxdetect' configuration option. When
744 'faxbuffers' is used and fax tones are detected, the channel will dynamically
745 switch to the configured faxbuffers policy. For example, to use 6 buffers
746 and a 'full' buffer policy for a fax transmission, add:
748 The faxbuffers configuration will be in affect until the call is torn down.
749 * Added service message support for 4ESS/5ESS switches.
753 * For DAHDI channels, the CHANNEL() dialplan function now
754 supports changing the channel's buffer policy (for the current
755 call only), using this syntax:
757 exten => s,n,Set(CHANNEL(buffers)=6,full)
759 This would change the channel to the 'full' buffer policy and
760 6 (six) buffers. Possible options for this setting are the same
761 as those in chan_dahdi.conf.
762 * Added a new dialplan function, CURLOPT, which permits setting various
763 options that may be useful with the CURL dialplan function, such as
764 cookies, proxies, connection timeouts, passwords, etc.
765 * Permit the syntax and synopsis fields of the corresponding dialplan
766 functions to be individually set from func_odbc.conf.
767 * Added debugging CLI functions to func_odbc, 'odbc read' and 'odbc write'.
768 * func_odbc now may specify an insert query to execute, when the write query
769 affects 0 rows (usually indicating that no such row exists).
770 * Added a new dialplan function, LISTFILTER, which permits removing elements
771 from a set list, by name. Uses the same general syntax as the existing CUT
772 and FIELDQTY dialplan functions, which also manage lists.
773 * Added REALTIME_FIELD and REALTIME_HASH, which should aid users in better
774 obtaining realtime data from the dialplan.
775 * Added LOCAL_PEEK, which allows access to variables in any stack frame within
776 a subroutine when using the GoSub() and Return() applications.
777 * Added AUDIOHOOK_INHERIT. For information on its use, please see the output
778 of "core show function AUDIOHOOK_INHERIT" from the CLI
779 * Added AES_ENCRYPT. For information on its use, please see the output
780 of "core show function AES_ENCRYPT" from the CLI
781 * Added AES_DECRYPT. For information on its use, please see the output
782 of "core show function AES_DECRYPT" from the CLI
783 * func_odbc now supports database transactions across multiple queries.
787 * Scheduled meetme conferences may now have their end times extended by
789 * app_authenticate now gives the ability to select a prompt other than
791 * app_directory now pays attention to the searchcontexts setting in
792 voicemail.conf and will look through all contexts, if no context is
793 specified in the initial argument.
794 * A new application, Originate, has been introduced, that allows asynchronous
795 call origination from the dialplan.
796 * Voicemail now permits setting the emailsubject and emailbody per mailbox,
797 in addition to the setting in the "general" context.
798 * Added ConfBridge dialplan application which does conference bridges without
799 DAHDI. For information on its use, please see the output of
800 "core show application ConfBridge" from the CLI.
804 * The Asterisk CLI has a new command, "channel redirect", which is similar in
805 operation to the AMI Redirect action.
806 * extensions.conf now allows you to use keyword "same" to define an extension
807 without actually specifying an extension. It uses exactly the same pattern
808 as previously used on the last "exten" line. For example:
809 exten => 123,1,NoOp(something)
810 same => n,SomethingElse()
811 * musiconhold.conf classes of type 'files' can now use relative directory paths,
812 which are interpreted as relative to the astvarlibdir setting in asterisk.conf.
813 * All deprecated CLI commands are removed from the sourcecode. They are now handled
814 by the new clialiases module. See cli_aliases.conf.sample file.
815 * Times within timespecs are now accurate down to the minute. This is a change
816 from historical Asterisk, which only provided timespecs rounded to the nearest
817 even (read: evenly divisible by 2) minute mark.
818 * The realtime switch now supports an option flag, 'p', which disables searches for
820 * In addition to a time range and date range, timespecs now accept a 5th optional
821 argument, timezone. This allows you to perform time checks on alternate
822 timezones, especially if those daylight savings time ranges vary from your
823 machine's native timezone. See GotoIfTime, ExecIfTime, IFTIME(), and timed
825 * The contrib/scripts/ directory now has a script called sip_nat_settings that will
826 give you the correct output for an asterisk box behind nat. It will give you the
827 externhost and localnet settings.
828 * The Asterisk core now supports ITU G.722.1 and G.722.1C media streams, and
829 can connect calls in passthrough mode, as well as record and play back files.
830 * Successful and unsuccessful call pickup can now be alerted through sounds, by
831 using pickupsound and pickupfailsound in features.conf.
832 * ASTVARRUNDIR is now set to $(localstatedir)/run/asterisk by default.
833 This means the asterisk pid file will now be in /var/run/asterisk/asterisk.pid on LINUX
834 instead of the /var/run/asterisk.pid where it used to be. This will make
835 installs as non-root easier to manage.
840 * The cdr.conf file must exist and be correctly programmed in order for CDR records to
841 be written; they will no longer be explicitly written.
843 Asterisk Manager Interface
844 --------------------------
845 * When using the AMI over HTTP, you can now include a 'SuppressEvents' header (with
846 a non-empty value) in your request. If you do this, any pending AMI events will
847 *not* be included in the response to your request as they would normally, but
848 will be left in the event queue for the next request you make to retrieve. For
849 some applications, this will allow you to guarantee that you will only see
850 events in responses to 'WaitEvent' actions, and can better know when to expect them.
851 To know whether the Asterisk server supports this header or not, your client can
852 inspect the first response back from the server to see if it includes this header:
854 Pragma: SuppressEvents
856 If this is included, the server supports event suppression.
858 * Added 4 new Actions to list skinny device(s) and line(s)
864 LDAP Schema File Additions
865 --------------------------
866 * Added AsteriskDialplan, AsteriskAccount and AsteriskMailbox objectClasses
867 to allow standalone dialplan, account and mailbox entries (STRUCTURAL)
869 - AstAccountLanguage, AstAccountTransport, AstAccountPromiscRedir,
870 - AstAccountAccountCode, AstAccountSetVar, AstAccountAllowOverlap,
871 - AstAccountVideoSupport, AstAccountIgnoreSDPVersion
872 * Removed redundant IPaddr (there's already IPAddress)
873 - Gives more configuration Flags for SIP-Users available (tested)
874 - Allows to create Asterisk Attributes in defined Asterisk ObjectClasses
875 without extensibleObject (which really should be the last resort); gives
876 also additional possibilities for LDAP-filter
878 ------------------------------------------------------------------------------
879 --- Functionality changes from Asterisk 1.6.0 to Asterisk 1.6.1 -------------
880 ------------------------------------------------------------------------------
882 Device State Handling
883 ---------------------
884 * The event infrastructure in Asterisk got another big update to help support
885 distributed events. It currently supports distributed device state and
886 distributed Voicemail MWI (Message Waiting Indication). A new module has
887 been merged, res_ais, which facilitates communicating events between servers.
888 It uses the SAForum AIS (Service Availability Forum Application Interface
889 Specification) CLM (Cluster Management) and EVT (Event) services to maintain
890 a cluster of Asterisk servers, and to share events between them. For more
891 information on setting this up, see doc/distributed_devstate.txt.
895 * Added a new dialplan function, AST_CONFIG(), which allows you to access
896 variables from an Asterisk configuration file.
897 * The JACK_HOOK function now has a c() option to supply a custom client name.
898 * Added two new dialplan functions from libspeex for audio gain control and
899 denoise, AGC() and DENOISE(). Both functions can be applied to the tx and
900 rx directions of a channel from the dialplan.
901 * The SMDI_MSG_RETRIEVE function now has the ability to search for SMDI messages
902 based on other parameters. The default is still to search based on the
903 forwarding station ID. However, there are new options that allow you to search
904 based on the message desk terminal ID, or the message desk number.
905 * TIMEOUT() has been modified to be accurate down to the millisecond.
906 * ENUM*() functions now include the following new options:
907 - 'u' returns the full URI and does not strip off the URI-scheme.
908 - 's' triggers ISN specific rewriting
909 - 'i' looks for branches into an Infrastructure ENUM tree
910 - 'd' for a direct DNS lookup without any flipping of digits.
911 * TXCIDNAME() has a new zone-suffix parameter (which defaults to 'e164.arpa')
912 * CHANNEL() now has options for the maximum, minimum, and standard or normal
913 deviation of jitter, rtt, and loss for a call using chan_sip.
915 DAHDI channel driver (chan_dahdi) Changes
916 ----------------------------------------
917 * Channels can now be configured using named sections in chan_dahdi.conf, just
918 like other channel drivers, including the use of templates.
919 * The default for pridialplan has changed from 'national' to 'unknown'.
923 * It is now possible to specify a pattern match as a hint. Once a phone subscribes
924 to something that matches the pattern a hint will be created using the contents
925 and variables evaluated.
926 * Dialplan matching has been extended to allow an extension to return to the
927 PBX core to wait for more digits. This is done by using the new dialplan
928 application called "Incomplete". This will permit a whole new level of
929 extension control, by giving the administrator more control over early
930 matches employing one of the short-circuit pattern match operators. Note
931 that custom applications can trigger this same behavior by returning the
932 special value AST_PBX_INCOMPLETE.
936 * Directory now permits both first and last names to be matched at the same
937 time. In addition, the number of digits to enter of the name can be set in
938 the arguments to Directory; previously, you could enter only 3, regardless
939 of how many names are in your company. For large companies, this should be
941 * Voicemail now permits a mailbox setting to wrap around from first to last
942 messages, if the "messagewrap" option is set to a true value.
943 * Voicemail now permits an external script to be run, for password validation.
944 The script should output "VALID" or "INVALID" on stdout, depending upon the
945 wish to validate or invalidate the password given. Arguments are:
946 "mailbox" "context" "oldpass" "newpass". See the sample voicemail.conf for
948 * Dial has a new option: F(context^extension^pri), which permits a callee to
949 continue in the dialplan, at the specified label, if the caller hangs up.
950 * ChanSpy and ExtenSpy have a new option, 's' which suppresses speaking the
951 technology name (e.g. SIP, IAX, etc) of the channel being spied on.
952 * The Jack application now has a c() option to supply a custom client name.
953 * Chanspy has a new option, 'B', which can be used to "barge" on a call. This is
954 like the pre-existing whisper mode, except that the spy can also talk to the
955 participant on the bridged channel as well.
956 * Chanspy has a new option, 'n', which will allow for the spied-on party's name
957 to be spoken instead of the channel name or number. For more information on the
958 use of this option, issue the command "core show application ChanSpy" from the
960 * Chanspy has a new option, 'd', which allows the spy to use DTMF to swap between
961 spy modes. Use of this feature overrides the typical use of numeric DTMF. In other
962 words, if using the 'd' option, it is not possible to enter a number to append to
963 the first argument to Chanspy(). Pressing 4 will change to spy mode, pressing 5 will
964 change to whisper mode, and pressing 6 will change to barge mode.
965 * ExternalIVR now takes several options that affect the way it performs, as
966 well as having several new commands. Please see doc/externalivr.txt for the
967 complete documentation.
968 * Added ability to communicate over a TCP socket instead of forking a child process for the
969 ExternalIVR application.
970 * ChanIsAvail has a new option, 'a', which will return all available channels instead
971 of just the first one if you give the function more then one channel to check.
972 * PrivacyManager now takes an option where you can specify a context where the
973 given number will be matched. This way you have more control over who is allowed
974 and it stops the people who blindly enter 10 digits.
975 * ForkCDR has new options: 'a' updates the answer time on the new CDR; 'A' locks
976 answer times, disposition, on orig CDR against updates; 'D' Copies the disposition
977 from the orig CDR to the new CDR after reset; 'e' sets the 'end' time on the
978 original CDR; 'R' prevents the new CDR from being reset; 's(var=val)' adds/changes
979 the 'var' variable on the original CDR; 'T' forces ast_cdr_end(), ast_cdr_answer(),
980 obey the LOCKED flag on cdr's in the chain, and also the ast_cdr_setvar() func.
981 * The Dial() application no longer copies the language used by the caller to the callee's
982 channel. If you desire for the caller's channel's language to be used for file playback
983 to the callee, then the file specified may be prepended with "${CHANNEL(language)}/" .
984 * SendImage() no longer hangs up the channel on error; instead, it sets the
985 status variable SENDIMAGESTATUS to one of 'SUCCESS', 'FAILURE', or
986 'UNSUPPORTED'. This change makes SendImage() more consistent with other
988 * Park has a new option, 's', which silences the announcement of the parking space number.
989 * A non-numeric, zero, or negative timeout specified to Dial() will now be interpreted as
990 invalid input and will be assumed to mean that no timeout is desired.
994 * Added DNS manager support to registrations for peers referencing peer entries.
995 DNS manager runs in the background which allows DNS lookups to be run asynchronously
996 as well as periodically updating the IP address. These properties allow for
997 better performance as well as recovery in the event of an IP change.
998 * Performance improvements via using hash tables (astobj2) and doubly-linked lists to improve
999 load/reload of large numbers of peers/users by ~40x (for large lists of peers).
1000 These changes also provide performance improvements for call setup and tear down.
1001 * Added ability to specify registration expiry time on a per registration basis in
1003 * Added support for T140 RED - redundancy in T.140 to prevent text loss due to
1005 * Added t38pt_usertpsource option. See sip.conf.sample for details.
1006 * Added SIPnotify AMI command, for sending arbitrary SIP notify commands.
1007 * 'sip show peers' and 'sip show users' display their entries sorted in
1008 alphabetical order, as opposed to the order they were in, in the config
1010 * Videosupport now supports an additional option, "always", which always sets
1011 up video RTP ports, even on clients that don't support it. This helps with
1012 callfiles and certain transfers to ensure that if two video phones are
1013 connected, they will always share video feeds.
1017 * Existing DNS manager lookups extended to check for SRV records.
1018 * IAX2 encryption support has been improved to support periodic key rotation
1019 within a call for enhanced security. The option "keyrotate" has been
1020 provided to disable this functionality to preserve backwards compatibility
1021 with older versions of IAX2 that do not support key rotation.
1025 * New CLI command, "data get <path> [<search> [<filter>]]" which retrieves the
1026 data tree based on the given <path>.
1027 * New CLI command "data show providers" that will display all the registered
1029 * New CLI command, "config reload <file.conf>" which reloads any module that
1030 references that particular configuration file. Also added "config list"
1031 which shows which configuration files are in use.
1032 * New CLI commands, "pri show version" and "ss7 show version" that will
1033 display which version of libpri and libss7 are being used, respectively.
1034 A new API call was added so trunk will now have to be compiled against
1035 a versions of libpri and libss7 that have them or it will not know that
1036 these libraries exist.
1037 * The commands "core show globals", "core set global" and "core set chanvar" has
1038 been deprecated in favor of the more semanticly correct "dialplan show globals",
1039 "dialplan set chanvar" and "dialplan set global".
1040 * New CLI command "dialplan show chanvar" to list all variables associated
1041 with a given channel.
1045 * Addresses managed by DNS manager now can check to see if there is a DNS
1046 SRV record for a given domain and will use that hostname/port if present.
1048 AMI - The manager (TCP/TLS/HTTP)
1049 --------------------------------
1050 * The Status command now takes an optional list of variables to display
1051 along with channel status.
1052 * The QueueEntry event now also includes the channel's uniqueid
1056 * res_odbc no longer has a limit of 1023 total possible unshared connections,
1057 as some people were running into this limit. This limit has been increased
1062 * The TRANSFER queue log entry now includes the the caller's original
1063 position in the transferred-from queue.
1064 * A new configuration option, "timeoutpriority" has been added. Please see the section labeled
1065 "QUEUE TIMING OPTIONS" in configs/queues.conf.sample for a detailed explanation of the option
1066 as well as an explanation about timeout options in general
1067 * Added a new option - C - for forcing the "answered elsewhere" flag on
1068 cancellation of calls in to members of the queue. This is to avoid the
1069 call to a member of a queue having the call listed as a "missed call".
1073 * Several (ODBC, Postgres, MySQL, SQLite) realtime drivers have been given
1074 adaptive capabilities. What this means in practical terms is that if your
1075 realtime table lacks critical fields, Asterisk will now emit warnings to
1076 that effect. Also, some of the realtime drivers have the ability (if
1077 configured) to automatically add those columns to the table with the
1078 correct type and length.
1082 * The channel variable ATTENDED_TRANSFER_COMPLETE_SOUND can now be set using
1083 the 'setvar' option to cause a given audio file to be played upon completion
1084 of an attended transfer. Currently it works for DAHDI, IAX2, SIP, and
1085 Skinny channels only.
1086 * You can now compile Asterisk against the Hoard Memory Allocator, see doc/hoard.txt
1087 for more information.
1088 * Config file variables may now be appended to, by using the '+=' append
1089 operator. This is most helpful when working with long SQL queries in
1090 func_odbc.conf, as the queries no longer need to be specified on a single
1092 * CDR config file, cdr.conf, has an added option, "initiatedseconds",
1093 which will add a second to the billsec when the ending
1094 time is set, if the number in the microseconds field of the end time is
1095 greater than the number of microseconds in the answer time. This allows
1096 users to count the 'initiated' seconds in their billing records.
1098 ------------------------------------------------------------------------------
1099 --- Functionality changes from Asterisk 1.4.X to Asterisk 1.6.0 -------------
1100 ------------------------------------------------------------------------------
1102 AMI - The manager (TCP/TLS/HTTP)
1103 --------------------------------
1104 * Manager has undergone a lot of changes, all of them documented
1105 in doc/manager_1_1.txt
1106 * Manager version has changed to 1.1
1107 * Added a new action 'CoreShowChannels' to list currently defined channels
1108 and some information about them.
1109 * Added a new action 'SIPshowregistry' to list SIP registrations.
1110 * Added TLS support for the manager interface and HTTP server
1111 * Added the URI redirect option for the built-in HTTP server
1112 * The output of CallerID in Manager events is now more consistent.
1113 CallerIDNum is used for number and CallerIDName for name.
1114 * Enable https support for builtin web server.
1115 See configs/http.conf.sample for details.
1116 * Added a new action, GetConfigJSON, which can return the contents of an
1117 Asterisk configuration file in JSON format. This is intended to help
1118 improve the performance of AJAX applications using the manager interface
1120 * SIP and IAX manager events now use "ChannelType" in all cases where we
1121 indicate channel driver. Previously, we used a mixture of "Channel"
1122 and "ChannelDriver" headers.
1123 * Added a "Bridge" action which allows you to bridge any two channels that
1124 are currently active on the system.
1125 * Added a "ListAllVoicemailUsers" action that allows you to get a list of all
1126 the voicemail users setup.
1127 * Added 'DBDel' and 'DBDelTree' manager commands.
1128 * cdr_manager now reports events via the "cdr" level, separating it from
1129 the very verbose "call" level.
1130 * Manager users are now stored in memory. If you change the manager account
1131 list (delete or add accounts) you need to reload manager.
1132 * Added Masquerade manager event for when a masquerade happens between
1134 * Added "manager reload" command for the CLI
1135 * Lots of commands that only provided information are now allowed under the
1136 Reporting privilege, instead of only under Call or System.
1137 * The IAX* commands now require either System or Reporting privilege, to
1138 mirror the privileges of the SIP* commands.
1139 * Added ability to retrieve list of categories in a config file.
1140 * Added ability to retrieve the content of a particular category.
1141 * Added ability to empty a context.
1142 * Created new action to create a new file.
1143 * Updated delete action to allow deletion by line number with respect to category.
1144 * Added new action insert to add new variable to category at specified line.
1145 * Updated action newcat to allow new category to be inserted in file above another
1147 * Added new event "JitterBufStats" in the IAX2 channel
1148 * Originate now requires the Originate privilege and, if you want to call out
1149 to a subshell, it requires the System privilege, as well. This was done to
1150 enhance manager security.
1151 * Originate now accepts codec settings with "Codecs: alaw, ulaw, h264"
1152 * New command: Atxfer. See doc/manager_1_1.txt for more details or
1153 manager show command Atxfer from the CLI
1154 * New command: IAXregistry. See doc/manager_1_1.txt for more details or
1155 manager show command IAXregistry from the CLI
1159 * Added the DEVICE_STATE() dialplan function which allows retrieving any device
1160 state in the dialplan, as well as creating custom device states that are
1161 controllable from the dialplan.
1162 * Extend CALLERID() function with "pres" and "ton" parameters to
1163 fetch string representation of calling number presentation indicator
1164 and numeric representation of type of calling number value.
1165 * MailboxExists converted to dialplan function
1166 * A new option to Dial() for telling IP phones not to count the call
1167 as "missed" when dial times out and cancels.
1168 * Added LOCK(), TRYLOCK(), and UNLOCK(), which provide a single level dialplan
1169 mutex. No deadlocks are possible, as LOCK() only allows a single lock to be
1170 held for any given channel. Also, locks are automatically freed when a
1172 * Added HINT() dialplan function that allows retrieving hint information.
1173 Hints are mappings between extensions and devices for the sake of
1174 determining the state of an extension. This function can retrieve the list
1175 of devices or the name associated with a hint.
1176 * Added EXTENSION_STATE() dialplan function which allows retrieving the state
1178 * Added SYSINFO() dialplan function which allows retrieval of system information
1179 * Added a new dialplan function, DIALPLAN_EXISTS(), which allows you to check for
1180 the existence of a dialplan target.
1181 * Added two new dialplan functions, TOUPPER and TOLOWER, which convert a string to
1182 upper and lower case, respectively.
1183 * When bridging, Asterisk sets the BRIDGEPVTCALLID to the channel drivers unique
1184 ID for the call (not the Asterisk call ID or unique ID), provided that the
1185 channel driver supports this. For SIP, you get the SIP call-ID for the
1186 bridged channel which you can store in the CDR with a custom field.
1190 * Added CLI permissions, config file: cli_permissions.conf
1191 default is to allow all commands for every local user/group.
1192 Also this new feature added three new CLI commands:
1193 - cli check permissions {<username>|@<groupname>|<username>@<groupname>} [<command>]
1194 - cli reload permissions
1195 - cli show permissions
1196 * New CLI command "core show hint" (usage: core show hint <exten>)
1197 * New CLI command "core show settings"
1198 * Added 'core show channels count' CLI command.
1199 * Added the ability to set the core debug and verbose values on a per-file basis.
1200 * Added 'queue pause member' and 'queue unpause member' CLI commands
1201 * Ability to set process limits ("ulimit") without restarting Asterisk
1202 * Enhanced "agi debug" to print the channel name as a prefix to the debug
1203 output to make debugging on busy systems much easier.
1204 * New CLI commands "dialplan set extenpatternmatching true/false"
1205 * New CLI command: "core set chanvar" to set a channel variable from the CLI.
1206 * Added an easy way to execute Asterisk CLI commands at startup. Any commands
1207 listed in the startup_commands section of cli.conf will get executed.
1208 * Added a CLI command, "devstate change", which allows you to set custom device
1209 states from the func_devstate module that provides the DEVICE_STATE() function
1210 and handling of the "Custom:" devices.
1211 * New CLI command: "sip show sched" which shows all ast_sched entries for sip,
1212 sorted into the different possible callbacks, with the number of entries
1213 currently scheduled for each. Gives you a feel for how busy the sip channel
1215 * Added 'skinny show lines verbose' CLI command. This will show the subs for every channel.
1216 * Cleanup another bunch of CLI commands. Now all modules follow the same schema.
1217 (Done by lmadsen, junky and mvanbaak during the devcon 2008)
1221 * Added a new 'faxdetect=yes|no' configuration option to sip.conf. When this
1222 option is enabled, Asterisk will watch for a CNG tone in the incoming audio
1223 for a received call. If it is detected, the channel will jump to the
1224 'fax' extension in the dialplan.
1225 * The default SIP useragent= identifier now includes the Asterisk version
1226 * A new option, match_auth_username in sip.conf changes the matching of incoming requests.
1227 If set, and the incoming request carries authentication info,
1228 the username to match in the users list is taken from the Digest header
1229 rather than from the From: field. This feature is considered experimental.
1230 * The "musiconhold" and "musicclass" settings in sip.conf are now removed,
1231 since they where replaced by "mohsuggest" and "mohinterpret" in version 1.4
1232 * The "localmask" setting was removed in version 1.2 and the reminder about it
1233 being removed is now also removed.
1234 * A new option "busylevel" for setting a level of calls where asterisk reports
1235 a device as busy, to separate it from call-limit. This value is also added
1236 to the SIP_PEER dialplan function.
1237 * A new realtime family called "sipregs" is now supported to store SIP registration
1238 data. If this family is defined, "sippeers" will be used for configuration and
1239 "sipregs" for registrations. If it's not defined, "sippeers" will be used for
1240 registration data, as before.
1241 * The SIPPEER function have new options for port address, call and pickup groups
1242 * Added support for T.140 realtime text in SIP/RTP
1243 * The "checkmwi" option has been removed from sip.conf, as it is no longer
1244 required due to the restructuring of how MWI is handled. See the descriptions
1245 in this file of the "pollmailboxes" and "pollfreq" options to voicemail.conf
1246 for more information.
1247 * Added rtpdest option to CHANNEL() dialplan function.
1248 * Added SIPREFERRINGCONTEXT and SIPREFERREDBYHDR variables which are set when a transfer takes place.
1249 * SIP now adds a header to the CANCEL if the call was answered by another phone
1250 in the same dial command, or if the new c option in dial() is used.
1251 * The new default is that 100 Trying is not sent on REGISTER attempts as the RFC specifically
1252 states it is not needed. For phones, however, that do require it the "registertrying" option
1253 has been added so it can be enabled.
1254 * A new option called "callcounter" (global/peer/user level) enables call counters needed
1255 for better status reports needed for queues and SIP subscriptions. (Call-Limit was previously
1256 used to enable this functionality).
1257 * New settings for timer T1 and timer B on a global level or per device. This makes it
1258 possible to force timeout faster on non-responsive SIP servers. These settings are
1259 considered advanced, so don't use them unless you have a problem.
1260 * Added a dial string option to be able to set the To: header in an INVITE to any
1262 * Added a new global and per-peer option, qualifyfreq, which allows you to configure
1263 the qualify frequency.
1264 * Added SIP Session Timers support (RFC 4028). This prevents stuck SIP sessions that
1265 were not properly torn down due to network or endpoint failures during an established
1267 * Added experimental TCP and TLS support for SIP. See doc/siptls.txt and
1268 configs/sip.conf.sample for more information on how it is used.
1269 * Added a new configuration option "authfailureevents" that enables manager events when
1270 a peer can't authenticate properly.
1271 * Added DNS manager support to registrations for peers not referencing a peer entry.
1275 * Added the trunkmaxsize configuration option to chan_iax2.
1276 * Added the srvlookup option to iax.conf
1277 * Added support for OSP. The token is set and retrieved through the CHANNEL()
1280 XMPP Google Talk/Jingle changes
1281 -------------------------------
1282 * Added the bindaddr option to gtalk.conf.
1286 * Added skinny show device, skinny show line, and skinny show settings CLI commands.
1287 * Proper codec support in chan_skinny.
1288 * Added settings for IP and Ethernet QoS requests
1292 * Added separate settings for media QoS in mgcp.conf
1294 Console Channel Driver changes
1295 ------------------------------
1296 * Added experimental support for video send & receive to chan_oss.
1297 This requires SDL and ffmpeg/avcodec, plus Video4Linux or X11 to act as
1300 Phone channel changes (chan_phone)
1301 ----------------------------------
1302 * Added G729 passthrough support to chan_phone for Sigma Designs boards.
1304 H.323 channel Changes
1305 ---------------------
1306 * H323 remote hold notification support added (by NOTIFY message
1307 and/or H.450 supplementary service)
1309 Local channel changes
1310 ---------------------
1311 * The device state functionality in the Local channel driver has been updated
1312 to indicate INUSE or NOT_INUSE when a Local channel is being used as opposed
1313 to just UNKNOWN if the extension exists.
1314 * Added jitterbuffer support for chan_local. This allows you to use the
1315 generic jitterbuffer on incoming calls going to Asterisk applications.
1316 For example, this would allow you to use a jitterbuffer for an incoming
1317 SIP call to Voicemail by putting a Local channel in the middle. This
1318 feature is enabled by using the 'j' option in the Dial string to the Local
1319 channel in conjunction with the existing 'n' option for local channels.
1320 * A 'b' option has been added which causes chan_local to return the actual channel
1321 that is behind it when queried. This is useful for transfer scenarios as the
1322 actual channel will be transferred, not the Local channel.
1324 Agent channel changes
1325 ----------------------
1326 * The ackcall and endcall options are now supplemented with options acceptdtmf
1327 and enddtmf. These allow for the DTMF keypress to be configurable. The options
1328 default to their old hard-coded values ('#' and '*' respectively) so this should
1329 not break any existing agent installations.
1331 DAHDI channel driver (chan_dahdi) Changes
1332 ----------------------------------------
1333 * SS7 support (via libss7 library)
1334 * In India, some carriers transmit CID via dtmf. Some code has been added
1335 that will handle some situations. The cidstart=polarity_IN choice has been added for
1336 those carriers that transmit CID via dtmf after a polarity change.
1337 * CID matching information is now shown when doing 'dialplan show'.
1338 * Added dahdi show version CLI command.
1339 * Added setvar support to chan_dahdi.conf channel entries.
1340 * Added two new options: mwimonitor and mwimonitornotify. These options allow
1341 you to enable MWI monitoring on FXO lines. When the MWI state changes,
1342 the script specified in the mwimonitornotify option is executed. An internal
1343 event indicating the new state of the mailbox is also generated, so that
1344 the normal MWI facilities in Asterisk work as usual.
1345 * Added signalling type 'auto', which attempts to use the same signalling type
1346 for a channel as configured in DAHDI. This is primarily designed for analog
1347 ports, but will also work for digital ports that are configured for FXS or FXO
1348 signalling types. This mode is also the default now, so if your chan_dahdi.conf
1349 does not specify signalling for a channel (which is unlikely as the sample
1350 configuration file has always recommended specifying it for every channel) then
1351 the 'auto' mode will be used for that channel if possible.
1352 * Added a 'dahdi set dnd' command to allow CLI control of the Do-Not-Disturb
1353 state for a channel; also ensured that the DNDState Manager event is
1354 emitted no matter how the DND state is set or cleared.
1358 * Added a new channel driver, chan_unistim. See doc/unistim.txt and
1359 configs/unistim.conf.sample for details. This new channel driver allows
1360 you to use Nortel i2002, i2004, and i2050 phones with Asterisk.
1361 * Added a new channel driver, chan_console, which uses portaudio as a cross
1362 platform audio interface. It was written as a channel driver that would
1363 work with Mac CoreAudio, but portaudio supports a number of other audio
1364 interfaces, as well. Note that this channel driver requires v19 or higher
1365 of portaudio; older versions have a different API.
1369 * Added the ability to specify arguments to the Dial application when using
1370 the DUNDi switch in the dialplan.
1371 * Added the ability to set weights for responses dynamically. This can be
1372 done using a global variable or a dialplan function. Using the SHELL()
1373 function would allow you to have an external script set the weight for
1375 * Added two new dialplan functions, DUNDIQUERY and DUNDIRESULT. These
1376 functions will allow you to initiate a DUNDi query from the dialplan,
1377 find out how many results there are, and access each one.
1378 * Added the ability to specifiy a port for a dundi peer.
1382 * Added two new dialplan functions, ENUMQUERY and ENUMRESULT. These
1383 functions will allow you to initiate an ENUM lookup from the dialplan,
1384 and Asterisk will cache the results. ENUMRESULT can be used to access
1385 the results without doing multiple DNS queries.
1389 * Added the ability to customize which sound files are used for some of the
1390 prompts within the Voicemail application by changing them in voicemail.conf
1391 * Added the ability for the "voicemail show users" CLI command to show users
1392 configured by the dynamic realtime configuration method.
1393 * MWI (Message Waiting Indication) handling has been significantly
1394 restructured internally to Asterisk. It is now totally event based
1395 instead of polling based. The voicemail application will notify other
1396 modules that have subscribed to MWI events when something in the mailbox
1398 This also means that if any other entity outside of Asterisk is changing
1399 the contents of mailboxes, then the voicemail application still needs to
1400 poll for changes. Examples of situations that would require this option
1401 are web interfaces to voicemail or an email client in the case of using
1402 IMAP storage. So, two new options have been added to voicemail.conf
1403 to account for this: "pollmailboxes" and "pollfreq". See the sample
1404 configuration file for details.
1405 * Added "tw" language support
1406 * Added support for storage of greetings using an IMAP server
1407 * Added ability to customize forward, reverse, stop, and pause keys for message playback
1408 * SMDI is now enabled in voicemail using the smdienable option.
1409 * A "lockmode" option has been added to asterisk.conf to configure the file
1410 locking method used for voicemail, and potentially other things in the
1411 future. The default is the old behavior, lockfile. However, there is a
1412 new method, "flock", that uses a different method for situations where the
1413 lockfile will not work, such as on SMB/CIFS mounts.
1414 * Added the ability to backup deleted messages, to ease recovery in the case
1415 that a user accidentally deletes a message, and discovers that they need it.
1416 * Reworked the SMDI interface in Asterisk. The new way to access SMDI information
1417 is through the new functions, SMDI_MSG_RETRIEVE() and SMDI_MSG(). The file
1418 smdi.conf can now be configured with options to map SMDI station IDs to Asterisk
1419 voicemail boxes. The SMDI interface can also poll for MWI changes when some
1420 outside entity is modifying the state of the mailbox (such as IMAP storage or
1421 a web interface of some kind).
1422 * Added the support for marking messages as "urgent." There are two methods to accomplish
1423 this. One is to pass the 'U' option to VoiceMail(). Another way to mark a message as urgent
1424 is to specify "review=yes" in voicemail.conf. Doing this will cause allow the user to mark
1425 the message as urgent after he has recorded a voicemail by following the voice instructions.
1426 When listening to voicemails using VoiceMailMain urgent messages will be presented before other
1431 * Added the general option 'shared_lastcall' so that member's wrapuptime may be
1432 used across multiple queues.
1433 * Added QUEUE_VARIABLES function to set queue variables added setqueuevar and
1434 setqueueentryvar options for each queue, see queues.conf.sample for details.
1435 * Added keepstats option to queues.conf which will keep queue
1436 statistics during a reload.
1437 * setinterfacevar option in queues.conf also now sets a variable
1438 called MEMBERNAME which contains the member's name.
1439 * Added 'Strategy' field to manager event QueueParams which represents
1440 the queue strategy in use.
1441 * Added option to run macro when a queue member is connected to a caller,
1442 see queues.conf.sample for details.
1443 * app_queue now has a 'loose' option which is almost exactly like 'strict' except it
1444 does not count paused queue members as unavailable.
1445 * Added min-announce-frequency option to queues.conf which allows you to control the
1446 minimum amount of time between queue announcements for use when the caller's queue
1447 position changes frequently.
1448 * Added additional information to EXITWITHTIMEOUT and EXITWITHKEY events in the
1450 * Added ability for non-realtime queues to have realtime members
1451 * Added the "linear" strategy to queues.
1452 * Added the "wrandom" strategy to queues.
1453 * Added new channel variable QUEUE_MIN_PENALTY
1454 * QUEUE_MAX_PENALTY and QUEUE_MIN_PENALTY may be adjusted in mid-call by defining
1455 rules in queuerules.conf. See configs/queuerules.conf.sample for details
1456 * Added a new parameter for member definition, called state_interface. This may be
1457 used so that a member may be called via one interface but have a different interface's
1458 device state reported.
1459 * Added new CLI and Manager commands relating to reloading queues. From the CLI, see
1460 "queue reload", "queue reset stats". Also see "manager show command QueueReload" and
1461 "manager show command QueueReset."
1462 * New configuration option: randomperiodicannounce. If a list of periodic announcements is
1463 specified by the periodic-announce option, then one will be chosen randomly when it is time
1464 to play a periodic announcment
1465 * New configuration options: announce-position now takes two more values in addition to "yes" and
1466 "no." Two new options, "limit" and "more," are allowed. These are tied to another option,
1467 announce-position-limit. By setting announce-position to "limit" callers will only have their
1468 position announced if their position is less than what is specified by announce-position-limit.
1469 If announce-position is set to "more" then callers beyond the position specified by announce-position-limit
1470 will be told that their are more than announce-position-limit callers waiting.
1471 * Two new queue log events have been added. An ADDMEMBER event will be logged
1472 when a realtime queue member is added and a REMOVEMEMBER event will be logged
1473 when a realtime queue member is removed. Since there is no calling channel associated
1474 with these events, the string "REALTIME" is placed where the channel's unique id
1475 is typically placed.
1476 * The configuration method for the "joinempty" and "leavewhenempty" options has
1477 changed to a comma-separated list of methods of determining member availability
1478 instead of vague terms such as "yes," "loose," "no," and "strict." These old four
1479 values are still accepted for backwards-compatibility, though.
1480 * The average talktime is now calculated on queues. This information is reported via the
1481 CLI commands "queue show" and "queues show"; through the AMI events AgentComplete, QueueSummary,
1482 and QueueParams; and through the channelvariable QUEUETALKTIME if setinterfacevar=yes is set for
1487 * The 'o' option to provide an optimization has been removed and its functionality
1488 has been enabled by default.
1489 * When a conference is created, the UNIQUEID of the channel that caused it to be
1490 created is stored. Then, every channel that joins the conference will have the
1491 MEETMEUNIQUEID channel variable set with this ID. This can be used to relate
1492 callers that come and go from long standing conferences.
1493 * Added a new application, MeetMeChannelAdmin, which is similar to MeetMeAdmin,
1494 except it does operations on a channel by name, instead of number in a conference.
1495 This is a very useful feature in combination with the 'X' option to ChanSpy.
1496 * Added 'C' option to Meetme which causes a caller to continue in the dialplan
1498 * Added new RealTime functionality to provide support for scheduled conferencing.
1499 This includes optional messages to the caller if they attempt to join before
1500 the schedule start time, or to allow the caller to join the conference early.
1501 Also included is optional support for limiting the number of callers per
1502 RealTime conference.
1503 * Added the S() and L() options to the MeetMe application. These are pretty
1504 much identical to the S() and L() options to Dial(). They let you set
1505 timeouts for the conference, as well as have warning sounds played to
1506 let the caller know how much time is left, and when it is running out.
1507 * Added the ability to do "meetme concise" with the "meetme" CLI command.
1508 This extends the concise capabilities of this CLI command to include
1509 listing all conferences, instead of an addition to the other sub commands
1510 for the "meetme" command.
1511 * Added the ability to specify the music on hold class used to play into the
1512 conference when there is only one member and the M option is used.
1513 * Added MEETME_INFO dialplan function which provides a way to query
1514 various properties of a Meetme conference.
1515 * Added new admin features: *81: Roll call, *82: eject all, *83: mute all,
1516 and *84: record in-conf
1518 Other Dialplan Application Changes
1519 ----------------------------------
1520 * Argument support for Gosub application
1521 * From the to-do lists: straighten out the app timeout args:
1522 Wait() app now really does 0.3 seconds- was truncating arg to an int.
1523 WaitExten() same as Wait().
1524 Congestion() - Now takes floating pt. argument.
1525 Busy() - now takes floating pt. argument.
1526 Read() - timeout now can be floating pt.
1527 WaitForRing() now takes floating pt timeout arg.
1528 SpeechBackground() -- clarified in the docstrings that the timeout is an integer seconds.
1529 * Added 's' option to Page application.
1530 * Added an optional timeout argument to the Page application.
1531 * Added 'E', 'V', and 'P' commands to ExternalIVR.
1532 * Added 'o' and 'X' options to Chanspy.
1533 * Added a new dialplan application, Bridge, which allows you to bridge the
1534 calling channel to any other active channel on the system.
1535 * Added the ability to specify a music on hold class to play instead of ringing
1536 for the SLATrunk application.
1537 * The Read application no longer exits the dialplan on error. Instead, it sets
1538 READSTATUS to ERROR, which you can catch and handle separately.
1539 * Added 'm' option to Directory, which lists out names, 8 at a time, instead
1540 of asking for verification of each name, one at a time.
1541 * Privacy() no longer uses privacy.conf, as all options are specifyable as
1542 direct options to the app.
1543 * AMD() has a new "maximum word length" option. "show application AMD" from the CLI
1545 * GotoIfTime() now may branch based on a "false" condition, like other Goto-related applications
1546 * The ChannelRedirect application no longer exits the dialplan if the given channel
1547 does not exist. It will now set the CHANNELREDIRECT_STATUS variable to SUCCESS upon success
1548 or NOCHANNEL if the given channel was not found.
1549 * The silencethreshold setting that was previously configurable in multiple
1550 applications is now settable globally via dsp.conf.
1552 Music On Hold Changes
1553 ---------------------
1554 * A new option, "digit", has been added for music on hold classes in
1555 musiconhold.conf. If this is set for a music on hold class, a caller
1556 listening to music on hold can press this digit to switch to listening
1557 to this music on hold class.
1558 * Support for realtime music on hold has been added.
1559 * In conjunction with the realtime music on hold, a general section has
1560 been added to musiconhold.conf, its sole variable is cachertclasses. If this
1561 is set, then music on hold classes found in realtime will be cached in memory.
1565 * AEL upgraded to use the Gosub with Arguments instead
1566 of Macro application, to hopefully reduce the problems
1567 seen with the artificially low stack ceiling that
1568 Macro bumps into. Macros can only call other Macros
1569 to a depth of 7. Tests run using gosub, show depths
1570 limited only by virtual memory. A small test demonstrated
1571 recursive call depths of 100,000 without problems.
1572 -- in addition to this, all apps that allowed a macro
1573 to be called, as in Dial, queues, etc, are now allowing
1574 a gosub call in similar fashion.
1575 * AEL now generates LOCAL(argname) declarations when it
1576 Set()'s the each arg name to the value of ${ARG1}, ${ARG2),
1577 etc. That makes the arguments local in scope. The user
1578 can define their own local variables in macros, now,
1579 by saying "local myvar=someval;" or using Set() in this
1580 fashion: Set(LOCAL(myvar)=someval); ("local" is now
1582 * utils/conf2ael introduced. Will convert an extensions.conf
1583 file into extensions.ael. Very crude and unfinished, but
1584 will be improved as time goes by. Should be useful for a
1585 first pass at conversion.
1586 * aelparse will now read extensions.conf to see if a referenced
1587 macro or context is there before issueing a warning.
1588 * AEL parser sets a local channel variable ~~EXTEN~~, to
1589 preserve the value of ${EXTEN} thru switch statements.
1590 * New operator in $[...] expressions: the ~~ operator serves
1591 as a concatenation operator. AT THE MOMENT, it is really only
1592 necessary and useful in AEL, especially in if() expressions.
1593 Operation: ${a} ~~ ${b| with force both a and b to strings, strip
1594 any enclosing double-quotes, and evaluate to the value of a
1595 concatenated with the value of b. For example if a is set to
1596 "xyz" and b has the value "abc", then ${a} ~~ ${b| would
1597 evaluate to xyzabc .
1600 Call Features (res_features) Changes
1601 ------------------------------------
1602 * Added the parkedcalltransfers option to features.conf
1603 * Added parkedcallparking option to control one touch parking w/ parking
1605 * Added parkedcallhangup option to control disconnect feature w/ parking
1607 * Added parkedcallrecording option to control one-touch record w/ parking
1609 * Added parkedcallparking, parkedcallhangup, parkedcallrecording, and
1610 parkedcalltransfers option support for multiple parking lots.
1611 * Added BRIDGE_FEATURES variable to set available features for a channel
1612 * The built-in method for doing attended transfers has been updated to
1613 include some new options that allow you to have the transferee sent
1614 back to the person that did the transfer if the transfer is not successful.
1615 See the options "atxferdropcall", "atxferloopdelay", and "atxfercallbackretries"
1616 in features.conf.sample.
1617 * Added support for configuring named groups of custom call features in
1618 features.conf. This means that features can be written a single time, and
1619 then mapped into groups of features for different key mappings or easier
1621 * Updated the ParkedCall application to allow you to not specify a parking
1622 extension. If you don't specify a parking space to pick up, it will grab
1623 the first one available.
1624 * Added cli command 'features reload' to reload call features from features.conf
1625 * Moved into core asterisk binary.
1626 * Changed the default setting for featuredigittimeout to 2000 ms from 500 ms.
1627 * Added the ability for custom parking lots to be configured with their own
1628 parking extension with the parkext option.
1630 Language Support Changes
1631 ------------------------
1632 * Brazilian Portuguese (pt-BR) in VM, and say.c was added
1633 * Added support for the Hungarian language for saying numbers, dates, and times.
1637 * Added SPEECH commands for speech recognition. A complete listing can be found
1639 * If app_stack is loaded, GOSUB is a native AGI command that may be used to
1640 invoke subroutines in the dialplan. Note that calling EXEC with Gosub
1641 does not behave as expected; the native command needs to be used, instead.
1642 * Added the ability to perform SRV lookups on fast AGI calls. To use this
1643 feature, simply use hagi: instead of agi: as the protocol portion
1644 of the URI parameter to the AGI function call in your dial plan. Also note
1645 that specifying a port number in the AGI URI will disable SRV lookups,
1646 even if you use the hagi: protocol.
1647 * No longer support MSG_OOB flag on HANGUP.
1651 * Added rotatestrategy option to logger.conf, along with two new options:
1652 "timestamp" which will use the time to name the logger files instead of
1653 sequence number; and "rotate", which rotates the names of the log files,
1654 similar to the way syslog rotates files.
1655 * Added exec_after_rotate option to logger.conf, which allows a system
1656 command to be run after rotation. This is primarily useful with
1657 rotatestrategy=rotate, to allow a limit on the number of log files kept
1658 and to ensure that the oldest log file gets deleted.
1659 * Added realtime support for the queue log
1663 * The cdr_manager module has a [mappings] feature, like cdr_custom,
1664 to add fields to the manager event from the CDR variables.
1665 * Added cdr_adaptive_odbc, a new module that adapts to the structure of your
1666 backend database CDR table. Specifically, additional, non-standard
1667 columns are supported, merely by setting the corresponding CDR variable in
1668 your dialplan. In addition, you may alias any column to another name (for
1669 example, if you want the 'src' CDR variable to be column 'ANI' in the DB,
1670 simply "alias src => ANI" in the configuration file). Records may be
1671 posted to more than one backend, simply by specifying multiple categories
1672 in the configuration file. And finally, you may filter which CDRs get
1673 posted to each backend, by specifying a filter (which the record must
1674 match) for the particular category. Filters are additive (meaning all
1675 rules must match to post that CDR).
1676 * The Postgres CDR module now supports some features of the cdr_adaptive_odbc
1677 module. Specifically, you may add additional columns into the table and
1678 they will be set, if you set the corresponding CDR variable name. Also,
1679 if you omit columns in your database table, they will be silently skipped
1680 (but a record will still be inserted, based on what columns remain). Note
1681 that the other two features from cdr_adaptive_odbc (alias and filter) are
1682 not currently supported.
1683 * The ResetCDR application now has an 'e' option that re-enables a CDR if it
1684 has been disabled using the NoCDR application.
1686 Miscellaneous New Modules
1687 -------------------------
1688 * Added a new CDR module, cdr_sqlite3_custom.
1689 * Added a new realtime configuration module, res_config_sqlite
1690 * Added a new codec translation module, codec_resample, which re-samples
1691 signed linear audio between 8 kHz and 16 kHz to help support wideband
1693 * Added a new module, res_phoneprov, which allows auto-provisioning of phones
1694 based on configuration templates that use Asterisk dialplan function and
1695 variable substitution. It should be possible to create phone profiles and
1696 templates that work for the majority of phones provisioned over http. It
1697 is currently only intended to provision a single user account per phone.
1698 An example profile and set of templates for Polycom phones is provided.
1699 NOTE: Polycom firmware is not included, but should be placed in
1700 AST_DATA_DIR/phoneprov/configs to match up with the included templates.
1701 * Added a new module, app_jack, which provides interfaces to JACK, the Jack
1702 Audio Connection Kit (http://www.jackaudio.org/). Two interfaces are
1703 provided; there is a JACK() application, and a JACK_HOOK() function. Both
1704 interfaces create an input and output JACK port. The application makes
1705 these ports the endpoint of the call. The audio coming from the channel
1706 goes out the output port and whatever comes back in on the input port is
1707 what gets sent to the channel. The JACK_HOOK() function turns on a JACK
1708 audiohook on the channel. This lets you run the audio coming from a
1709 channel through JACK, and whatever comes back in is what gets forwarded
1710 on as the channel's audio. This is very useful for building custom
1711 vocoders or doing recording or analysis of the channel's audio in another
1713 * Added a new module, res_config_curl, which permits using a HTTP POST url
1714 to retrieve, create, update, and delete realtime information from a remote
1715 web server. Note that this module requires func_curl.so to be loaded for
1716 backend functionality.
1717 * Added a new module, res_config_ldap, which permits the use of an LDAP
1718 server for realtime data access.
1719 * Added support for writing and running your dialplan in lua using the pbx_lua
1720 module. See configs/extensions.lua.sample for examples of how to do this.
1724 * Ability to use libcap to set high ToS bits when non-root
1725 on Linux. If configure is unable to find libcap then you
1726 can use --with-cap to specify the path.
1727 * Added maxfiles option to options section of asterisk.conf which allows you to specify
1728 what Asterisk should set as the maximum number of open files when it loads.
1729 * Added the jittertargetextra configuration option.
1730 * Added support for setting the CoS for VLAN traffic (802.1p). See the sample
1731 configuration files for the IP channel drivers. The new option is "cos".
1732 This information is also documented in doc/qos.tex, or the IP Quality of Service
1733 section of asterisk.pdf.
1734 * When originating a call using AMI or pbx_spool that fails the reason for failure
1735 will now be available in the failed extension using the REASON dialplan variable.
1736 * Added support for reading the TOUCH_MONITOR_PREFIX channel variable.
1737 It allows you to configure a prefix for auto-monitor recordings.
1738 * A new extension pattern matching algorithm, based on a trie, is introduced
1739 here, that could noticeably speed up mid-sized to large dialplans.
1740 It is NOT used by default, as duplicating the behaviour of the old pattern
1741 matcher is still under development. A config file option, in extensions.conf,
1742 in the [general] section, called "extenpatternmatchingnew", is by default
1743 set to false; setting that to true will force the use of the new algorithm.
1744 Also, the cli commands "dialplan set extenpatternmatchingnew true/false" can
1745 be used to switch the algorithms at run time.
1746 * A new option when starting a remote asterisk (rasterisk, asterisk -r) for
1747 specifying which socket to use to connect to the running Asterisk daemon
1749 * Performance enhancements to the sched facility, which is used in
1750 the channel drivers, etc. Added hashtabs and doubly-linked lists
1751 to speed up deletion; start at the beginning or end of list to
1753 * Added Doubly-linked lists after the fashion of linkedlists.h. They are in
1754 dlinkedlists.h. Doubly-linked lists feature fast deletion times.
1755 Added regression tests to the tests/ dir, also.
1756 * Added a refcount trace feature to astobj2 for those trying to balance
1757 object creation, deletion; work, play; space and time. See the
1758 notes in astobj2.h. Also, see utils/refcounter as well, as a
1759 quick way to find unbalanced refcounts in what could be a sea
1760 of objects that were balanced.
1761 * Added logging to 'make update' command. See update.log
1762 * Added strictrtp option to rtp.conf. If enabled this will drop RTP packets that
1763 do not come from the remote party.
1764 * Added the 'n' option to the SpeechBackground application to tell it to not
1765 answer the channel if it has not already been answered.
1766 * Added a compiler flag, CHANNEL_TRACE, which permits channel tracing to be
1767 turned on, via the CHANNEL(trace) dialplan function. Could be useful for
1769 * iLBC source code no longer included (see UPGRADE.txt for details)
1770 * If compiled with DETECT_DEADLOCKS enabled and if you have glibc, then if
1771 deadlock is detected, a backtrace of the stack which led to the lock calls
1772 will be output to the CLI.
1773 * If compiled with DEBUG_THREADS enabled and if you have glibc, then issuing
1774 the "core show locks" CLI command will give lock information output as well
1775 as a backtrace of the stack which led to the lock calls.
1776 * users.conf now sports an optional alternateexts property, which permits
1777 allocation of additional extensions which will reach the specified user.
1778 * A new option for the configure script, --enable-internal-poll, has been added
1779 for use with systems which may have a buggy implementation of the poll system
1780 call. If you notice odd behavior such as the CLI being unresponsive on remote
1781 consoles, you may want to try using this option. This option is enabled by default
1782 on Darwin systems since it is known that the Darwin poll() implementation has
1786 --------------------
1787 * In addition to timing from DAHDI, there is a new timing module called
1788 res_timing_timerfd. In order to use this, you must be running Linux with
1789 a kernel version 2.6.25 or newer as well as glibc 2.8 or newer. The configure
1790 script will be able to tell if you have the requirements. From menuselect, select
1791 res_timing_timerfd from the Resource Modules menu.
