3 === This file documents the new and/or enhanced functionality added in
4 === the Asterisk versions listed below. This file does NOT include
5 === changes in behavior that would not be backwards compatible with
6 === previous versions; for that information see the UPGRADE.txt file
7 === and the other UPGRADE files for older releases.
9 ======================================================================
11 ------------------------------------------------------------------------------
12 --- Functionality changes from Asterisk 1.6.2 to Asterisk 1.8 ----------------
13 ------------------------------------------------------------------------------
17 * Added preferred_codec_only option in sip.conf. This feature limits the joint
18 codecs sent in response to an INVITE to the single most preferred codec.
19 * Added SIP_CODEC_OUTBOUND dialplan variable which can be used to set the codec
20 to be used for the outgoing call. It must be one of the codecs configured
22 * Added tlsprivatekey option to sip.conf. This allows a separate .pem file
23 to be used for holding a private key. If tlsprivatekey is not specified,
24 tlscertfile is searched for both public and private key.
25 * Added tlsclientmethod option to sip.conf. This allows the protocol for
26 outbound client connections to be specified.
27 * The sendrpid parameter has been expanded to include the options
28 'rpid' and 'pai'. Setting sendrpid to 'rpid' will cause Remote-Party-ID
29 header to be sent (equivalent to setting sendrpid=yes) and setting
30 sendrpid to 'pai' will cause P-Asserted-Identity header to be sent.
31 * The 'ignoresdpversion' behavior has been made automatic when the SDP received
32 is in response to a T.38 re-INVITE that Asterisk initiated. In this situation,
33 since the call will fail if Asterisk does not process the incoming SDP, Asterisk
34 will accept the SDP even if the SDP version number is not properly incremented,
35 but will generate a warning in the log indicating that the SIP peer that sent
36 the SDP should have the 'ignoresdpversion' option set.
37 * The 'nat' option has now been been changed to have yes, no, force_rport, and
38 comedia as valid values. Setting it to yes forces RFC 3581 behavior and enables
39 symmetric RTP support. Setting it to no only enables RFC 3581 behavior if the
40 remote side requests it and disables symmetric RTP support. Setting it to
41 force_rport forces RFC 3581 behavior and disables symmetric RTP support.
42 Setting it to comedia enables RFC 3581 behavior if the remote side requests it
43 and enables symmetric RTP support.
44 * Slave SIP channels now set HASH(SIP_CAUSE,<slave-channel-name>) on each
45 response. This permits the master channel to know how each channel dialled
46 in a multi-channel setup resolved in an individual way.
47 * Added 'externtcpport' and 'externtlsport' options to allow custom port
48 configuration for the externip and externhost options when tcp or tls is used.
49 * Added support for message body (stored in content variable) to SIP NOTIFY message
50 accessible via AMI and CLI.
51 * Added 'media_address' configuration option which can be used to explicitly specify
52 the IP address to use in the SDP for media (audio, video, and text) streams.
53 * Added 'unsolicited_mailbox' configuration option which specifies the virtual mailbox
54 that the new/old count should be stored on if an unsolicited MWI NOTIFY message is
56 * Added 'use_q850_reason' configuration option for generating and parsing
57 if available Reason: Q.850;cause=<cause code> header. It is implemented
58 in some gateways for better passing PRI/SS7 cause codes via SIP.
62 * Added rtsavesysname option into iax.conf to allow the systname to be saved
67 * Added ability to preset channel variables on indicated lines with the setvar
68 configuration option. Also, clearvars=all resets the list of variables back
70 * PacketCable NCS 1.0 support has been added for Docsis/Eurodocsis Networks.
71 See configs/res_pktccops.conf for more information.
75 * Added progress option to the app_dial D() option. When progress DTMF is
76 present, those values are sent immediately upon receiving a PROGRESS message
77 regardless if the call has been answered or not.
78 * Added functionality to the app_dial F() option to continue with execution
79 at the current location when no parameters are provided.
80 * Added c() option to app_chanspy. This option allows custom DTMF to be set
81 to cycle through the next available channel. By default this is still '*'.
82 * Added x() option to app_chanspy. This option allows DTMF to be set to
84 * The Voicemail application has been improved to automatically ignore messages
85 that only contain silence.
86 * The ChanSpy application now has the 'S' option, which makes the application
87 automatically exit once it hits a point where no more channels are available
89 * The ChanSpy application also now has the 'E' option, which spies on a single
90 channel and exits when that channel hangs up.
91 * The MeetMe application now turns on the DENOISE() function by default, for
92 each participant. In our tests, this has significantly decreased background
93 noise (especially noisy data centers).
94 * Voicemail now permits storage of secrets in a separate file, located in the
95 spool directory of each individual user. The control for this is located in
96 the "passwordlocation" option in voicemail.conf. Please see the sample
97 configuration for more information.
101 * Added new dialplan functions CONNECTEDLINE and REDIRECTING which permits
102 setting various connected line and redirecting party information.
103 * CALLERID and CONNECTEDLINE dialplan functions have been extended to
104 support ISDN subaddressing.
105 * The CHANNEL() function now supports the "name" option.
106 * For DAHDI channels, the CHANNEL() dialplan function now
107 supports changing the channel's buffer policy (for the current
108 call only), using this syntax:
110 exten => s,n,Set(CHANNEL(buffers)=6,full)
112 This would change the channel to the 'full' buffer policy and
113 6 (six) buffers. Possible options for this setting are the same
114 as those in chan_dahdi.conf.
115 * For DAHDI channels, the CHANNEL() dialplan function now allows
116 the dialplan to request changes in the configuration of the active
117 echo canceller on the channel (if any), for the current call only.
120 exten => s,n,Set(CHANNEL(echocan_mode)=off)
122 The possible values are:
124 on - normal mode (the echo canceller is actually reinitialized)
126 fax - FAX/data mode (NLP disabled if possible, otherwise completely
128 voice - voice mode (returns from FAX mode, reverting the changes that
129 were made when FAX mode was requested)
130 * Added new dialplan function MASTER_CHANNEL(), which permits retrieving
131 and setting variables on the channel which created the current channel.
132 Administrators should take care to avoid naming conflicts, when multiple
133 channels are dialled at once, especially when used with the Local channel
134 construct (which all could set variables on the master channel). Usage
135 of the HASH() dialplan function, with the key set to the name of the slave
136 channel, is one approach that will avoid conflicts.
137 * Added new dialplan function MUTEAUDIO() for muting inbound and/or outbound
139 * func_odbc now allows multiple row results to be retrieved without using
140 mode=multirow. If rowlimit is set, then additional rows may be retrieved
141 from the same query by using the name of the function which retrieved the
142 first row as an argument to ODBC_FETCH().
143 * Added JABBER_RECEIVE, which permits receiving XMPP messages from the
144 dialplan. This function returns the content of the received message.
148 * Added DYNAMIC_FEATURENAME which holds the last triggered dynamic feature.
149 * Added DYNAMIC_PEERNAME which holds the unique channel name on the other side
150 and is set when a dynamic feature is triggered.
154 * A new option, 'I' has been added to both app_queue and app_dial.
155 By setting this option, Asterisk will not update the caller with
156 connected line changes or redirecting party changes when they occur.
158 mISDN channel driver (chan_misdn) changes
159 ----------------------------------------
160 * Added display_connected parameter to misdn.conf to put a display string
161 in the CONNECT message containing the connected name and/or number if
162 the presentation setting permits it.
163 * Added display_setup parameter to misdn.conf to put a display string
164 in the SETUP message containing the caller name and/or number if the
165 presentation setting permits it.
166 * Made misdn.conf parameters localdialplan and cpndialplan take a -1 to
167 indicate the dialplan settings are to be obtained from the asterisk
169 * Made misdn.conf parameter callerid accept the "name" <number> format
170 used by the rest of the system.
171 * Made use the nationalprefix and internationalprefix misdn.conf
172 parameters to prefix any received number from the ISDN link if that
173 number has the corresponding Type-Of-Number. NOTE: This includes
174 comparing the incoming call's dialed number against the MSN list.
175 * Added the following new parameters: unknownprefix, netspecificprefix,
176 subscriberprefix, and abbreviatedprefix in misdn.conf to prefix any
177 received number from the ISDN link if that number has the corresponding
179 * Added new dialplan application misdn_command which permits controlling
180 the CCBS/CCNR functionality.
181 * Added new dialplan function mISDN_CC which permits retrieval of various
182 values from an active call completion record.
183 * For PTP, you should manually send the COLR of the redirected-to party
184 for an incomming redirected call if the incoming call could experience
185 further redirects. Just set the REDIRECTING(to-num,i) = ${EXTEN} and
186 set the REDIRECTING(to-pres) to the COLR. A call has been redirected
187 if the REDIRECTING(from-num) is not empty.
188 * For outgoing PTP redirected calls, you now need to use the inhibit(i)
189 option on all of the REDIRECTING statements before dialing the
190 redirected-to party. You still have to set the REDIRECTING(to-xxx,i)
191 and the REDIRECTING(from-xxx,i) values. The PTP call will update the
192 redirecting-to presentation (COLR) when it becomes available.
193 * Added outgoing_colp parameter to misdn.conf to filter outgoing COLP
196 thirdparty mISDN enhancements
197 -----------------------------
198 mISDN has been modified by Digium, Inc. to greatly expand facility message
200 * Enhanced COLP support for call diversion and transfer.
203 The latest modified mISDN v1.1.x based version is available at:
204 http://svn.digium.com/svn/thirdparty/mISDN/trunk
205 http://svn.digium.com/svn/thirdparty/mISDNuser/trunk
207 Tagged versions of the modified mISDN code are available under:
208 http://svn.digium.com/svn/thirdparty/mISDN/tags
209 http://svn.digium.com/svn/thirdparty/mISDNuser/tags
211 libpri channel driver (chan_dahdi) DAHDI changes
212 -------------------------------------------
213 * The channel variable PRIREDIRECTREASON is now just a status variable
214 and it is also deprecated. Use the REDIRECTING(reason) dialplan function
215 to read and alter the reason.
216 * For Q.SIG and ETSI PRI/BRI-PTP, you should manually send the COLR of the
217 redirected-to party for an incomming redirected call if the incoming call
218 could experience further redirects. Just set the
219 REDIRECTING(to-num,i) = CALLERID(dnid) and set the REDIRECTING(to-pres)
220 to the COLR. A call has been redirected if the REDIRECTING(count) is not
222 * For outgoing Q.SIG and ETSI PRI/BRI-PTP redirected calls, you need to
223 use the inhibit(i) option on all of the REDIRECTING statements before
224 dialing the redirected-to party. You still have to set the
225 REDIRECTING(to-xxx,i) and the REDIRECTING(from-xxx,i) values. The call
226 will update the redirecting-to presentation (COLR) when it becomes available.
227 * Added Reverse Charging Indication receipt & transmission (requires latest
229 * Added the ability to ignore calls that are not in a Multiple Subscriber
230 Number (MSN) list for PTMP CPE interfaces.
231 * Added dynamic range compression support for dahdi channels. It is
232 configured via the rxdrc and txdrc parameters in chan_dahdi.conf.
233 * Added support for ISDN calling and called subaddress with partial support
234 for connected line subaddress.
235 * Added support for BRI PTMP NT mode. (Requires latest LibPRI.)
236 * Added handling of received HOLD/RETRIEVE messages and the optional ability
237 to transfer a held call on disconnect similar to an analog phone.
238 * Added CallRerouting/CallDeflection support for Q.SIG, ETSI PTP, ETSI PTMP.
239 Will reroute/deflect an outgoing call when receive the message.
240 Can use the DAHDISendCallreroutingFacility to send the message for the
242 * Added ability to send/receive keypad digits in the SETUP message.
243 Send keypad digits in SETUP message: Dial(DAHDI/g1[/K<keypad_digits>][/extension])
244 Access any received keypad digits in SETUP message by: ${CHANNEL(keypad_digits)}
246 Asterisk Manager Interface
247 --------------------------
248 * The Hangup action now accepts a Cause header which may be used to
249 set the channel's hangup cause.
250 * sslprivatekey option added to manager.conf and http.conf. Adds the ability
251 to specify a separate .pem file to hold a private key. By default sslcert
252 is used to hold both the public and private key.
253 * Options in manager.conf and http.conf with the 'ssl' prefix have been replaced
254 for options containing the 'tls' prefix. For example, 'sslenable' is now
255 'tlsenable'. This has been done in effort to keep ssl and tls options consistent
256 across all .conf files. All affected sample.conf files have been modified to
257 reflect this change. Previous options such as 'sslenable' still work,
258 but options with the 'tls' prefix are preferred.
259 * Added a MuteAudio AMI action for muting inbound and/or outbound audio
260 in a channel. (res_mutestream.so)
262 Channel Event Logging
263 ---------------------
264 * A new interface, CEL, is introduced here. CEL logs single events, much like
265 the AMI, but it differs from the AMI in that it logs to db backends much
266 like CDR does; is based on the event subsystem introduced by Russell, and
267 can share in all its benefits; allows multiple backends to operate like CDR;
268 is specialized to event data that would be of concern to billing sytems,
269 like CDR. Backends for logging and accounting calls have been produced,
270 but a new CDR backend is still in development.
274 * 'linkedid' and 'peeraccount' are new CDR fields available to CDR officianados.
275 linkedid is based on uniqueID, but spreads to other channels as transfers, dials,
276 etc are performed. Thus the peices of CDR can be grouped into multilegged sets.
277 * Multiple files and formats can now be specified in cdr_custom.conf.
278 * cdr_syslog has been added which allows CDRs to be written directly to syslog.
279 See configs/cdr_syslog.conf.sample for more information.
280 * A 'sequence' field has been added to CDRs which can be combined with
281 linkedid or uniqueid to uniquely identify a CDR.
283 Calendaring for Asterisk
284 ------------------------
285 * A new set of modules were added supporing calendar integration with Asterisk.
286 Dialplan functions for reading from and writing to calendars are included,
287 as well as the ability to execute dialplan logic upon calendar event notifications.
288 iCalendar, CalDAV, and Exchange Server calendars are supported (Exchange support
289 only tested on Exchange Server 2003 with no support for forms-based authentication).
291 Multicast RTP Support
292 ---------------------
293 * A new RTP engine and channel driver have been added which supports Multicast RTP.
294 The channel driver can be used with the Page application to perform multicast RTP
295 paging. The dial string format is: MulticastRTP/<type>/<destination>/<control address>
296 Type can be either basic or linksys.
297 Destination is the IP address and port for the RTP packets.
298 Control address is specific to the linksys type and is used for sending the control
299 packets unique to them.
301 Security Events Framework
302 -------------------------
303 * Asterisk has a new C API for reporting security events. The module res_security_log
304 sends these events to the "security" logger level. Currently, AMI is the only
305 Asterisk component that reports security events. However, SIP support will be
306 coming soon. For more information on the security events framework, see the
307 "Security Events" chapter of the included documentation - doc/tex/asterisk.pdf.
311 * SendText is now implemented in chan_gtalk and chan_jingle. It will simply send
312 XMPP text messages to the remote JID.
314 ------------------------------------------------------------------------------
315 --- Functionality changes from Asterisk 1.6.1 to Asterisk 1.6.2 -------------
316 ------------------------------------------------------------------------------
320 * Added support for SUBSCRIBE/NOTIFY with dialog-info based call pickups.
321 Snom phones use this for call pickup of extensions that the phone is
323 * Added support for subscribing to a voice mailbox on a remote server and
324 making the new/old message count available to local devices.
325 * Added support for setting the domain in the URI for caller of an
326 outbound call by using the SIPFROMDOMAIN channel variable.
327 * Added a new configuration option "remotesecret" for authentication to
328 remote services. For backwards compatibility, "secret" still has the
329 same function as before, but now you can configure both a remote secret and a
330 local secret for mutual authentication.
331 * Added a new 'faxdetect=yes|no' configuration option to sip.conf. When this
332 option is enabled, a SIP channel will go to the fax extension (if it exists)
333 after T38 is negotiated. This option is disabled by default.
334 * If the channel variable ATTENDED_TRANSFER_COMPLETE_SOUND is set,
335 the sound will be played to the target of an attended transfer
336 * Added two new configuration options, "qualifygap" and "qualifypeers", which allow
337 finer control over how many peers Asterisk will qualify and the gap between them
338 when all peers need to be qualified at the same time.
339 * Added a new 'ignoresdpversion' option to sip.conf. When this is enabled
340 (either globally or for a specific peer), chan_sip will treat any SDP data
341 it receives as new data and update the media stream accordingly. By
342 default, Asterisk will only modify the media stream if the SDP session
343 version received is different from the current SDP session version. This
344 option is required to interoperate with devices that have non-standard SDP
345 session version implementations (observed with Microsoft OCS). This option
346 is disabled by default.
347 * The parsing of register => lines in sip.conf has been modified to allow a port
348 to be present in the "user" portion. Please see the sip.conf.sample file for more
350 * Added support for subscribing to MWI on a remote server and making the status available
351 as a mailbox. Please see the sip.conf.sample file for more information.
352 * Added a function to remove SIP headers added in the dialplan before the
353 first INVITE is generated - SIPRemoveHeader()
354 * Channel variables set with setvar= in a device configuration is now
355 set both for inbound and outbound calls.
356 * Added support for ITU G.722.1 and G.722.1C (Siren7 and Siren14) media streams.
360 * Added immediate option to iax.conf
361 * Added forceencryption option to iax.conf
362 * Added Encryption and Trunk status to manager command "iaxpeers"
366 * The configuration file now holds separate sections for devices and lines.
367 Please have a look at configs/skinny.conf.sample and change your skinny.conf
372 * chan_dahdi now supports MFC/R2 signaling when Asterisk is compiled with
373 support for LibOpenR2. http://www.libopenr2.org/
374 * The UK option waitfordialtone has been added for use with BT analog
376 * Added a 'faxbuffers' configuration option to chan_dahdi.conf. This option
377 is used in conjunction with the 'faxdetect' configuration option. When
378 'faxbuffers' is used and fax tones are detected, the channel will dynamically
379 switch to the configured faxbuffers policy. For example, to use 6 buffers
380 and a 'full' buffer policy for a fax transmission, add:
382 The faxbuffers configuration will be in affect until the call is torn down.
383 * Added service message support for 4ESS/5ESS switches.
387 * Added a new dialplan function, CURLOPT, which permits setting various
388 options that may be useful with the CURL dialplan function, such as
389 cookies, proxies, connection timeouts, passwords, etc.
390 * Permit the syntax and synopsis fields of the corresponding dialplan
391 functions to be individually set from func_odbc.conf.
392 * Added debugging CLI functions to func_odbc, 'odbc read' and 'odbc write'.
393 * func_odbc now may specify an insert query to execute, when the write query
394 affects 0 rows (usually indicating that no such row exists).
395 * Added a new dialplan function, LISTFILTER, which permits removing elements
396 from a set list, by name. Uses the same general syntax as the existing CUT
397 and FIELDQTY dialplan functions, which also manage lists.
398 * Added REALTIME_FIELD and REALTIME_HASH, which should aid users in better
399 obtaining realtime data from the dialplan.
400 * Added LOCAL_PEEK, which I have no idea how to use, but Leif Madsen wanted it.
401 Russell says it's, like, a scope resolution function for LOCAL variables.
402 Totally. Hopefully, that means more to you than it does to me.
403 * Added AUDIOHOOK_INHERIT. For information on its use, please see the output
404 of "core show function AUDIOHOOK_INHERIT" from the CLI
405 * Added AES_ENCRYPT. For information on its use, please see the output
406 of "core show function AES_ENCRYPT" from the CLI
407 * Added AES_DECRYPT. For information on its use, please see the output
408 of "core show function AES_DECRYPT" from the CLI
409 * func_odbc now supports database transactions across multiple queries.
413 * DAHDISendCallreroutingFacility parameters are now comma-separated,
414 instead of the old pipe.
415 * Scheduled meetme conferences may now have their end times extended by
417 * app_authenticate now gives the ability to select a prompt other than
419 * app_directory now pays attention to the searchcontexts setting in
420 voicemail.conf and will look through all contexts, if no context is
421 specified in the initial argument.
422 * A new application, Originate, has been introduced, that allows asynchronous
423 call origination from the dialplan.
424 * Voicemail now permits setting the emailsubject and emailbody per mailbox,
425 in addition to the setting in the "general" context.
426 * Added ConfBridge dialplan application which does conference bridges without
427 DAHDI. For information on its use, please see the output of
428 "core show application ConfBridge" from the CLI.
432 * The Asterisk CLI has a new command, "channel redirect", which is similar in
433 operation to the AMI Redirect action.
434 * res_jabber: autoprune has been disabled by default, to avoid misconfiguration
435 that would end up being interpreted as a bug once Asterisk started removing
436 the contacts from a user list.
437 * extensions.conf now allows you to use keyword "same" to define an extension
438 without actually specifying an extension. It uses exactly the same pattern
439 as previously used on the last "exten" line. For example:
440 exten => 123,1,NoOp(something)
441 same => n,SomethingElse()
442 * musiconhold.conf classes of type 'files' can now use relative directory paths,
443 which are interpreted as relative to the astvarlibdir setting in asterisk.conf.
444 * All deprecated CLI commands are removed from the sourcecode. They are now handled
445 by the new clialiases module. See cli_aliases.conf.sample file.
446 * Times within timespecs are now accurate down to the minute. This is a change
447 from historical Asterisk, which only provided timespecs rounded to the nearest
448 even (read: evenly divisible by 2) minute mark.
449 * The realtime switch now supports an option flag, 'p', which disables searches for
451 * In addition to a time range and date range, timespecs now accept a 5th optional
452 argument, timezone. This allows you to perform time checks on alternate
453 timezones, especially if those daylight savings time ranges vary from your
454 machine's native timezone. See GotoIfTime, ExecIfTime, IFTIME(), and timed
456 * The contrib/scripts/ directory now has a script called sip_nat_settings that will
457 give you the correct output for an asterisk box behind nat. It will give you the
458 externhost and localnet settings.
459 * The Asterisk core now supports ITU G.722.1 and G.722.1C media streams, and
460 can connect calls in passthrough mode, as well as record and play back files.
461 * Successful and unsuccessful call pickup can now be alerted through sounds, by
462 using pickupsound and pickupfailsound in features.conf.
463 * ASTVARRUNDIR is now set to $(localstatedir)/run/asterisk by default.
464 This means the asterisk pid file will now be in /var/run/asterisk/asterisk.pid on LINUX
465 instead of the /var/run/asterisk.pid where it used to be. This will make
466 installs as non-root easier to manage.
468 Asterisk Manager Interface
469 --------------------------
470 * When using the AMI over HTTP, you can now include a 'SuppressEvents' header (with
471 a non-empty value) in your request. If you do this, any pending AMI events will
472 *not* be included in the response to your request as they would normally, but
473 will be left in the event queue for the next request you make to retrieve. For
474 some applications, this will allow you to guarantee that you will only see
475 events in responses to 'WaitEvent' actions, and can better know when to expect them.
476 To know whether the Asterisk server supports this header or not, your client can
477 inspect the first response back from the server to see if it includes this header:
479 Pragma: SuppressEvents
481 If this is included, the server supports event suppression.
483 * Added 4 new Actions to list skinny device(s) and line(s)
489 ------------------------------------------------------------------------------
490 --- Functionality changes from Asterisk 1.6.0 to Asterisk 1.6.1 -------------
491 ------------------------------------------------------------------------------
493 Device State Handling
494 ---------------------
495 * The event infrastructure in Asterisk got another big update to help support
496 distributed events. It currently supports distributed device state and
497 distributed Voicemail MWI (Message Waiting Indication). A new module has
498 been merged, res_ais, which facilitates communicating events between servers.
499 It uses the SAForum AIS (Service Availability Forum Application Interface
500 Specification) CLM (Cluster Management) and EVT (Event) services to maintain
501 a cluster of Asterisk servers, and to share events between them. For more
502 information on setting this up, see doc/distributed_devstate.txt.
506 * Added a new dialplan function, AST_CONFIG(), which allows you to access
507 variables from an Asterisk configuration file.
508 * The JACK_HOOK function now has a c() option to supply a custom client name.
509 * Added two new dialplan functions from libspeex for audio gain control and
510 denoise, AGC() and DENOISE(). Both functions can be applied to the tx and
511 rx directions of a channel from the dialplan.
512 * The SMDI_MSG_RETRIEVE function now has the ability to search for SMDI messages
513 based on other parameters. The default is still to search based on the
514 forwarding station ID. However, there are new options that allow you to search
515 based on the message desk terminal ID, or the message desk number.
516 * TIMEOUT() has been modified to be accurate down to the millisecond.
517 * ENUM*() functions now include the following new options:
518 - 'u' returns the full URI and does not strip off the URI-scheme.
519 - 's' triggers ISN specific rewriting
520 - 'i' looks for branches into an Infrastructure ENUM tree
521 - 'd' for a direct DNS lookup without any flipping of digits.
522 * TXCIDNAME() has a new zone-suffix parameter (which defaults to 'e164.arpa')
523 * CHANNEL() now has options for the maximum, minimum, and standard or normal
524 deviation of jitter, rtt, and loss for a call using chan_sip.
526 DAHDI channel driver (chan_dahdi) Changes
527 ----------------------------------------
528 * Channels can now be configured using named sections in chan_dahdi.conf, just
529 like other channel drivers, including the use of templates.
530 * The default for pridialplan has changed from 'national' to 'unknown'.
534 * It is now possible to specify a pattern match as a hint. Once a phone subscribes
535 to something that matches the pattern a hint will be created using the contents
536 and variables evaluated.
537 * Dialplan matching has been extended to allow an extension to return to the
538 PBX core to wait for more digits. This is done by using the new dialplan
539 application called "Incomplete". This will permit a whole new level of
540 extension control, by giving the administrator more control over early
541 matches employing one of the short-circuit pattern match operators. Note
542 that custom applications can trigger this same behavior by returning the
543 special value AST_PBX_INCOMPLETE.
547 * Directory now permits both first and last names to be matched at the same
548 time. In addition, the number of digits to enter of the name can be set in
549 the arguments to Directory; previously, you could enter only 3, regardless
550 of how many names are in your company. For large companies, this should be
552 * Voicemail now permits a mailbox setting to wrap around from first to last
553 messages, if the "messagewrap" option is set to a true value.
554 * Voicemail now permits an external script to be run, for password validation.
555 The script should output "VALID" or "INVALID" on stdout, depending upon the
556 wish to validate or invalidate the password given. Arguments are:
557 "mailbox" "context" "oldpass" "newpass". See the sample voicemail.conf for
559 * Dial has a new option: F(context^extension^pri), which permits a callee to
560 continue in the dialplan, at the specified label, if the caller hangs up.
561 * ChanSpy and ExtenSpy have a new option, 's' which suppresses speaking the
562 technology name (e.g. SIP, IAX, etc) of the channel being spied on.
563 * The Jack application now has a c() option to supply a custom client name.
564 * Chanspy has a new option, 'B', which can be used to "barge" on a call. This is
565 like the pre-existing whisper mode, except that the spy can also talk to the
566 participant on the bridged channel as well.
567 * Chanspy has a new option, 'n', which will allow for the spied-on party's name
568 to be spoken instead of the channel name or number. For more information on the
569 use of this option, issue the command "core show application ChanSpy" from the
571 * Chanspy has a new option, 'd', which allows the spy to use DTMF to swap between
572 spy modes. Use of this feature overrides the typical use of numeric DTMF. In other
573 words, if using the 'd' option, it is not possible to enter a number to append to
574 the first argument to Chanspy(). Pressing 4 will change to spy mode, pressing 5 will
575 change to whisper mode, and pressing 6 will change to barge mode.
576 * ExternalIVR now takes several options that affect the way it performs, as
577 well as having several new commands. Please see doc/externalivr.txt for the
578 complete documentation.
579 * Added ability to communicate over a TCP socket instead of forking a child process for the
580 ExternalIVR application.
581 * ChanIsAvail has a new option, 'a', which will return all available channels instead
582 of just the first one if you give the function more then one channel to check.
583 * PrivacyManager now takes an option where you can specify a context where the
584 given number will be matched. This way you have more control over who is allowed
585 and it stops the people who blindly enter 10 digits.
586 * ForkCDR has new options: 'a' updates the answer time on the new CDR; 'A' locks
587 answer times, disposition, on orig CDR against updates; 'D' Copies the disposition
588 from the orig CDR to the new CDR after reset; 'e' sets the 'end' time on the
589 original CDR; 'R' prevents the new CDR from being reset; 's(var=val)' adds/changes
590 the 'var' variable on the original CDR; 'T' forces ast_cdr_end(), ast_cdr_answer(),
591 obey the LOCKED flag on cdr's in the chain, and also the ast_cdr_setvar() func.
592 * The Dial() application no longer copies the language used by the caller to the callee's
593 channel. If you desire for the caller's channel's language to be used for file playback
594 to the callee, then the file specified may be prepended with "${CHANNEL(language)}/" .
595 * SendImage() no longer hangs up the channel on error; instead, it sets the
596 status variable SENDIMAGESTATUS to one of 'SUCCESS', 'FAILURE', or
597 'UNSUPPORTED'. This change makes SendImage() more consistent with other
599 * Park has a new option, 's', which silences the announcement of the parking space number.
600 * A non-numeric, zero, or negative timeout specified to Dial() will now be interpreted as
601 invalid input and will be assumed to mean that no timeout is desired.
605 * Added DNS manager support to registrations for peers referencing peer entries.
606 DNS manager runs in the background which allows DNS lookups to be run asynchronously
607 as well as periodically updating the IP address. These properties allow for
608 better performance as well as recovery in the event of an IP change.
609 * Performance improvements via using hash tables (astobj2) and doubly-linked lists to improve
610 load/reload of large numbers of peers/users by ~40x (for large lists of peers).
611 These changes also provide performance improvements for call setup and tear down.
612 * Added ability to specify registration expiry time on a per registration basis in
614 * Added support for T140 RED - redundancy in T.140 to prevent text loss due to
616 * Added t38pt_usertpsource option. See sip.conf.sample for details.
617 * Added SIPnotify AMI command, for sending arbitrary SIP notify commands.
618 * 'sip show peers' and 'sip show users' display their entries sorted in
619 alphabetical order, as opposed to the order they were in, in the config
621 * Videosupport now supports an additional option, "always", which always sets
622 up video RTP ports, even on clients that don't support it. This helps with
623 callfiles and certain transfers to ensure that if two video phones are
624 connected, they will always share video feeds.
628 * Existing DNS manager lookups extended to check for SRV records.
629 * IAX2 encryption support has been improved to support periodic key rotation
630 within a call for enhanced security. The option "keyrotate" has been
631 provided to disable this functionality to preserve backwards compatibility
632 with older versions of IAX2 that do not support key rotation.
636 * New CLI command, "config reload <file.conf>" which reloads any module that
637 references that particular configuration file. Also added "config list"
638 which shows which configuration files are in use.
639 * New CLI commands, "pri show version" and "ss7 show version" that will
640 display which version of libpri and libss7 are being used, respectively.
641 A new API call was added so trunk will now have to be compiled against
642 a versions of libpri and libss7 that have them or it will not know that
643 these libraries exist.
644 * The commands "core show globals", "core set global" and "core set chanvar" has
645 been deprecated in favor of the more semanticly correct "dialplan show globals",
646 "dialplan set chanvar" and "dialplan set global".
647 * New CLI command "dialplan show chanvar" to list all variables associated
648 with a given channel.
652 * Addresses managed by DNS manager now can check to see if there is a DNS
653 SRV record for a given domain and will use that hostname/port if present.
655 AMI - The manager (TCP/TLS/HTTP)
656 --------------------------------
657 * The Status command now takes an optional list of variables to display
658 along with channel status.
659 * The QueueEntry event now also includes the channel's uniqueid
663 * res_odbc no longer has a limit of 1023 total possible unshared connections,
664 as some people were running into this limit. This limit has been increased
669 * The TRANSFER queue log entry now includes the the caller's original
670 position in the transferred-from queue.
671 * A new configuration option, "timeoutpriority" has been added. Please see the section labeled
672 "QUEUE TIMING OPTIONS" in configs/queues.conf.sample for a detailed explanation of the option
673 as well as an explanation about timeout options in general
674 * Added a new option - C - for forcing the "answered elsewhere" flag on
675 cancellation of calls in to members of the queue. This is to avoid the
676 call to a member of a queue having the call listed as a "missed call".
680 * Several (ODBC, Postgres, MySQL, SQLite) realtime drivers have been given
681 adaptive capabilities. What this means in practical terms is that if your
682 realtime table lacks critical fields, Asterisk will now emit warnings to
683 that effect. Also, some of the realtime drivers have the ability (if
684 configured) to automatically add those columns to the table with the
685 correct type and length.
689 * The channel variable ATTENDED_TRANSFER_COMPLETE_SOUND can now be set using
690 the 'setvar' option to cause a given audio file to be played upon completion
691 of an attended transfer. Currently it works for DAHDI, IAX2, SIP, and
692 Skinny channels only.
693 * You can now compile Asterisk against the Hoard Memory Allocator, see doc/hoard.txt
694 for more information.
695 * Config file variables may now be appended to, by using the '+=' append
696 operator. This is most helpful when working with long SQL queries in
697 func_odbc.conf, as the queries no longer need to be specified on a single
699 * CDR config file, cdr.conf, has an added option, "initiatedseconds",
700 which will add a second to the billsec when the ending
701 time is set, if the number in the microseconds field of the end time is
702 greater than the number of microseconds in the answer time. This allows
703 users to count the 'initiated' seconds in their billing records.
705 ------------------------------------------------------------------------------
706 --- Functionality changes from Asterisk 1.4.X to Asterisk 1.6.0 -------------
707 ------------------------------------------------------------------------------
709 AMI - The manager (TCP/TLS/HTTP)
710 --------------------------------
711 * Manager has undergone a lot of changes, all of them documented
712 in doc/manager_1_1.txt
713 * Manager version has changed to 1.1
714 * Added a new action 'CoreShowChannels' to list currently defined channels
715 and some information about them.
716 * Added a new action 'SIPshowregistry' to list SIP registrations.
717 * Added TLS support for the manager interface and HTTP server
718 * Added the URI redirect option for the built-in HTTP server
719 * The output of CallerID in Manager events is now more consistent.
720 CallerIDNum is used for number and CallerIDName for name.
721 * Enable https support for builtin web server.
722 See configs/http.conf.sample for details.
723 * Added a new action, GetConfigJSON, which can return the contents of an
724 Asterisk configuration file in JSON format. This is intended to help
725 improve the performance of AJAX applications using the manager interface
727 * SIP and IAX manager events now use "ChannelType" in all cases where we
728 indicate channel driver. Previously, we used a mixture of "Channel"
729 and "ChannelDriver" headers.
730 * Added a "Bridge" action which allows you to bridge any two channels that
731 are currently active on the system.
732 * Added a "ListAllVoicemailUsers" action that allows you to get a list of all
733 the voicemail users setup.
734 * Added 'DBDel' and 'DBDelTree' manager commands.
735 * cdr_manager now reports events via the "cdr" level, separating it from
736 the very verbose "call" level.
737 * Manager users are now stored in memory. If you change the manager account
738 list (delete or add accounts) you need to reload manager.
739 * Added Masquerade manager event for when a masquerade happens between
741 * Added "manager reload" command for the CLI
742 * Lots of commands that only provided information are now allowed under the
743 Reporting privilege, instead of only under Call or System.
744 * The IAX* commands now require either System or Reporting privilege, to
745 mirror the privileges of the SIP* commands.
746 * Added ability to retrieve list of categories in a config file.
747 * Added ability to retrieve the content of a particular category.
748 * Added ability to empty a context.
749 * Created new action to create a new file.
750 * Updated delete action to allow deletion by line number with respect to category.
751 * Added new action insert to add new variable to category at specified line.
752 * Updated action newcat to allow new category to be inserted in file above another
754 * Added new event "JitterBufStats" in the IAX2 channel
755 * Originate now requires the Originate privilege and, if you want to call out
756 to a subshell, it requires the System privilege, as well. This was done to
757 enhance manager security.
758 * Originate now accepts codec settings with "Codecs: alaw, ulaw, h264"
759 * New command: Atxfer. See doc/manager_1_1.txt for more details or
760 manager show command Atxfer from the CLI
761 * New command: IAXregistry. See doc/manager_1_1.txt for more details or
762 manager show command IAXregistry from the CLI
766 * Added the DEVICE_STATE() dialplan function which allows retrieving any device
767 state in the dialplan, as well as creating custom device states that are
768 controllable from the dialplan.
769 * Extend CALLERID() function with "pres" and "ton" parameters to
770 fetch string representation of calling number presentation indicator
771 and numeric representation of type of calling number value.
772 * MailboxExists converted to dialplan function
773 * A new option to Dial() for telling IP phones not to count the call
774 as "missed" when dial times out and cancels.
775 * Added LOCK(), TRYLOCK(), and UNLOCK(), which provide a single level dialplan
776 mutex. No deadlocks are possible, as LOCK() only allows a single lock to be
777 held for any given channel. Also, locks are automatically freed when a
779 * Added HINT() dialplan function that allows retrieving hint information.
780 Hints are mappings between extensions and devices for the sake of
781 determining the state of an extension. This function can retrieve the list
782 of devices or the name associated with a hint.
783 * Added EXTENSION_STATE() dialplan function which allows retrieving the state
785 * Added SYSINFO() dialplan function which allows retrieval of system information
786 * Added a new dialplan function, DIALPLAN_EXISTS(), which allows you to check for
787 the existence of a dialplan target.
788 * Added two new dialplan functions, TOUPPER and TOLOWER, which convert a string to
789 upper and lower case, respectively.
790 * When bridging, Asterisk sets the BRIDGEPVTCALLID to the channel drivers unique
791 ID for the call (not the Asterisk call ID or unique ID), provided that the
792 channel driver supports this. For SIP, you get the SIP call-ID for the
793 bridged channel which you can store in the CDR with a custom field.
797 * Added CLI permissions, config file: cli_permissions.conf
798 default is to allow all commands for every local user/group.
799 Also this new feature added three new CLI commands:
800 - cli check permissions {<username>|@<groupname>|<username>@<groupname>} [<command>]
801 - cli reload permissions
802 - cli show permissions
803 * New CLI command "core show hint" (usage: core show hint <exten>)
804 * New CLI command "core show settings"
805 * Added 'core show channels count' CLI command.
806 * Added the ability to set the core debug and verbose values on a per-file basis.
807 * Added 'queue pause member' and 'queue unpause member' CLI commands
808 * Ability to set process limits ("ulimit") without restarting Asterisk
809 * Enhanced "agi debug" to print the channel name as a prefix to the debug
810 output to make debugging on busy systems much easier.
811 * New CLI commands "dialplan set extenpatternmatching true/false"
812 * New CLI command: "core set chanvar" to set a channel variable from the CLI.
813 * Added an easy way to execute Asterisk CLI commands at startup. Any commands
814 listed in the startup_commands section of cli.conf will get executed.
815 * Added a CLI command, "devstate change", which allows you to set custom device
816 states from the func_devstate module that provides the DEVICE_STATE() function
817 and handling of the "Custom:" devices.
818 * New CLI command: "sip show sched" which shows all ast_sched entries for sip,
819 sorted into the different possible callbacks, with the number of entries
820 currently scheduled for each. Gives you a feel for how busy the sip channel
822 * Added 'skinny show lines verbose' CLI command. This will show the subs for every channel.
823 * Cleanup another bunch of CLI commands. Now all modules follow the same schema.
824 (Done by lmadsen, junky and mvanbaak during the devcon 2008)
828 * Improved NAT and STUN support.
829 chan_sip now can use port numbers in bindaddr, externip and externhost
830 options, as well as contact a STUN server to detect its external address
831 for the SIP socket. See sip.conf.sample, 'NAT' section.
832 * The default SIP useragent= identifier now includes the Asterisk version
833 * A new option, match_auth_username in sip.conf changes the matching of incoming requests.
834 If set, and the incoming request carries authentication info,
835 the username to match in the users list is taken from the Digest header
836 rather than from the From: field. This feature is considered experimental.
837 * The "musiconhold" and "musicclass" settings in sip.conf are now removed,
838 since they where replaced by "mohsuggest" and "mohinterpret" in version 1.4
839 * The "localmask" setting was removed in version 1.2 and the reminder about it
840 being removed is now also removed.
841 * A new option "busylevel" for setting a level of calls where asterisk reports
842 a device as busy, to separate it from call-limit. This value is also added
843 to the SIP_PEER dialplan function.
844 * A new realtime family called "sipregs" is now supported to store SIP registration
845 data. If this family is defined, "sippeers" will be used for configuration and
846 "sipregs" for registrations. If it's not defined, "sippeers" will be used for
847 registration data, as before.
848 * The SIPPEER function have new options for port address, call and pickup groups
849 * Added support for T.140 realtime text in SIP/RTP
850 * The "checkmwi" option has been removed from sip.conf, as it is no longer
851 required due to the restructuring of how MWI is handled. See the descriptions
852 in this file of the "pollmailboxes" and "pollfreq" options to voicemail.conf
853 for more information.
854 * Added rtpdest option to CHANNEL() dialplan function.
855 * Added SIPREFERRINGCONTEXT and SIPREFERREDBYHDR variables which are set when a transfer takes place.
856 * SIP now adds a header to the CANCEL if the call was answered by another phone
857 in the same dial command, or if the new c option in dial() is used.
858 * The new default is that 100 Trying is not sent on REGISTER attempts as the RFC specifically
859 states it is not needed. For phones, however, that do require it the "registertrying" option
860 has been added so it can be enabled.
861 * A new option called "callcounter" (global/peer/user level) enables call counters needed
862 for better status reports needed for queues and SIP subscriptions. (Call-Limit was previously
863 used to enable this functionality).
864 * New settings for timer T1 and timer B on a global level or per device. This makes it
865 possible to force timeout faster on non-responsive SIP servers. These settings are
866 considered advanced, so don't use them unless you have a problem.
867 * Added a dial string option to be able to set the To: header in an INVITE to any
869 * Added a new global and per-peer option, qualifyfreq, which allows you to configure
870 the qualify frequency.
871 * Added SIP Session Timers support (RFC 4028). This prevents stuck SIP sessions that
872 were not properly torn down due to network or endpoint failures during an established
874 * Added experimental TCP and TLS support for SIP. See doc/siptls.txt and
875 configs/sip.conf.sample for more information on how it is used.
876 * Added a new configuration option "authfailureevents" that enables manager events when
877 a peer can't authenticate properly.
878 * Added DNS manager support to registrations for peers not referencing a peer entry.
882 * Added the trunkmaxsize configuration option to chan_iax2.
883 * Added the srvlookup option to iax.conf
884 * Added support for OSP. The token is set and retrieved through the CHANNEL()
887 XMPP Google Talk/Jingle changes
888 -------------------------------
889 * Added the bindaddr option to gtalk.conf.
893 * Added skinny show device, skinny show line, and skinny show settings CLI commands.
894 * Proper codec support in chan_skinny.
895 * Added settings for IP and Ethernet QoS requests
899 * Added separate settings for media QoS in mgcp.conf
901 Console Channel Driver changes
902 ------------------------------
903 * Added experimental support for video send & receive to chan_oss.
904 This requires SDL and ffmpeg/avcodec, plus Video4Linux or X11 to act as
907 Phone channel changes (chan_phone)
908 ----------------------------------
909 * Added G729 passthrough support to chan_phone for Sigma Designs boards.
911 H.323 channel Changes
912 ---------------------
913 * H323 remote hold notification support added (by NOTIFY message
914 and/or H.450 supplementary service)
916 Local channel changes
917 ---------------------
918 * The device state functionality in the Local channel driver has been updated
919 to indicate INUSE or NOT_INUSE when a Local channel is being used as opposed
920 to just UNKNOWN if the extension exists.
921 * Added jitterbuffer support for chan_local. This allows you to use the
922 generic jitterbuffer on incoming calls going to Asterisk applications.
923 For example, this would allow you to use a jitterbuffer for an incoming
924 SIP call to Voicemail by putting a Local channel in the middle. This
925 feature is enabled by using the 'j' option in the Dial string to the Local
926 channel in conjunction with the existing 'n' option for local channels.
927 * A 'b' option has been added which causes chan_local to return the actual channel
928 that is behind it when queried. This is useful for transfer scenarios as the
929 actual channel will be transferred, not the Local channel.
931 Agent channel changes
932 ----------------------
933 * The ackcall and endcall options are now supplemented with options acceptdtmf
934 and enddtmf. These allow for the DTMF keypress to be configurable. The options
935 default to their old hard-coded values ('#' and '*' respectively) so this should
936 not break any existing agent installations.
938 DAHDI channel driver (chan_dahdi) Changes
939 ----------------------------------------
940 * SS7 support (via libss7 library)
941 * In India, some carriers transmit CID via dtmf. Some code has been added
942 that will handle some situations. The cidstart=polarity_IN choice has been added for
943 those carriers that transmit CID via dtmf after a polarity change.
944 * CID matching information is now shown when doing 'dialplan show'.
945 * Added dahdi show version CLI command.
946 * Added setvar support to chan_dahdi.conf channel entries.
947 * Added two new options: mwimonitor and mwimonitornotify. These options allow
948 you to enable MWI monitoring on FXO lines. When the MWI state changes,
949 the script specified in the mwimonitornotify option is executed. An internal
950 event indicating the new state of the mailbox is also generated, so that
951 the normal MWI facilities in Asterisk work as usual.
952 * Added signalling type 'auto', which attempts to use the same signalling type
953 for a channel as configured in DAHDI. This is primarily designed for analog
954 ports, but will also work for digital ports that are configured for FXS or FXO
955 signalling types. This mode is also the default now, so if your chan_dahdi.conf
956 does not specify signalling for a channel (which is unlikely as the sample
957 configuration file has always recommended specifying it for every channel) then
958 the 'auto' mode will be used for that channel if possible.
959 * Added a 'dahdi set dnd' command to allow CLI control of the Do-Not-Disturb
960 state for a channel; also ensured that the DNDState Manager event is
961 emitted no matter how the DND state is set or cleared.
965 * Added a new channel driver, chan_unistim. See doc/unistim.txt and
966 configs/unistim.conf.sample for details. This new channel driver allows
967 you to use Nortel i2002, i2004, and i2050 phones with Asterisk.
968 * Added a new channel driver, chan_console, which uses portaudio as a cross
969 platform audio interface. It was written as a channel driver that would
970 work with Mac CoreAudio, but portaudio supports a number of other audio
971 interfaces, as well. Note that this channel driver requires v19 or higher
972 of portaudio; older versions have a different API.
976 * Added the ability to specify arguments to the Dial application when using
977 the DUNDi switch in the dialplan.
978 * Added the ability to set weights for responses dynamically. This can be
979 done using a global variable or a dialplan function. Using the SHELL()
980 function would allow you to have an external script set the weight for
982 * Added two new dialplan functions, DUNDIQUERY and DUNDIRESULT. These
983 functions will allow you to initiate a DUNDi query from the dialplan,
984 find out how many results there are, and access each one.
988 * Added two new dialplan functions, ENUMQUERY and ENUMRESULT. These
989 functions will allow you to initiate an ENUM lookup from the dialplan,
990 and Asterisk will cache the results. ENUMRESULT can be used to access
991 the results without doing multiple DNS queries.
995 * Added the ability to customize which sound files are used for some of the
996 prompts within the Voicemail application by changing them in voicemail.conf
997 * Added the ability for the "voicemail show users" CLI command to show users
998 configured by the dynamic realtime configuration method.
999 * MWI (Message Waiting Indication) handling has been significantly
1000 restructured internally to Asterisk. It is now totally event based
1001 instead of polling based. The voicemail application will notify other
1002 modules that have subscribed to MWI events when something in the mailbox
1004 This also means that if any other entity outside of Asterisk is changing
1005 the contents of mailboxes, then the voicemail application still needs to
1006 poll for changes. Examples of situations that would require this option
1007 are web interfaces to voicemail or an email client in the case of using
1008 IMAP storage. So, two new options have been added to voicemail.conf
1009 to account for this: "pollmailboxes" and "pollfreq". See the sample
1010 configuration file for details.
1011 * Added "tw" language support
1012 * Added support for storage of greetings using an IMAP server
1013 * Added ability to customize forward, reverse, stop, and pause keys for message playback
1014 * SMDI is now enabled in voicemail using the smdienable option.
1015 * A "lockmode" option has been added to asterisk.conf to configure the file
1016 locking method used for voicemail, and potentially other things in the
1017 future. The default is the old behavior, lockfile. However, there is a
1018 new method, "flock", that uses a different method for situations where the
1019 lockfile will not work, such as on SMB/CIFS mounts.
1020 * Added the ability to backup deleted messages, to ease recovery in the case
1021 that a user accidentally deletes a message, and discovers that they need it.
1022 * Reworked the SMDI interface in Asterisk. The new way to access SMDI information
1023 is through the new functions, SMDI_MSG_RETRIEVE() and SMDI_MSG(). The file
1024 smdi.conf can now be configured with options to map SMDI station IDs to Asterisk
1025 voicemail boxes. The SMDI interface can also poll for MWI changes when some
1026 outside entity is modifying the state of the mailbox (such as IMAP storage or
1027 a web interface of some kind).
1028 * Added the support for marking messages as "urgent." There are two methods to accomplish
1029 this. One is to pass the 'U' option to VoiceMail(). Another way to mark a message as urgent
1030 is to specify "review=yes" in voicemail.conf. Doing this will cause allow the user to mark
1031 the message as urgent after he has recorded a voicemail by following the voice instructions.
1032 When listening to voicemails using VoiceMailMain urgent messages will be presented before other
1037 * Added the general option 'shared_lastcall' so that member's wrapuptime may be
1038 used across multiple queues.
1039 * Added QUEUE_VARIABLES function to set queue variables added setqueuevar and
1040 setqueueentryvar options for each queue, see queues.conf.sample for details.
1041 * Added keepstats option to queues.conf which will keep queue
1042 statistics during a reload.
1043 * setinterfacevar option in queues.conf also now sets a variable
1044 called MEMBERNAME which contains the member's name.
1045 * Added 'Strategy' field to manager event QueueParams which represents
1046 the queue strategy in use.
1047 * Added option to run macro when a queue member is connected to a caller,
1048 see queues.conf.sample for details.
1049 * app_queue now has a 'loose' option which is almost exactly like 'strict' except it
1050 does not count paused queue members as unavailable.
1051 * Added min-announce-frequency option to queues.conf which allows you to control the
1052 minimum amount of time between queue announcements for use when the caller's queue
1053 position changes frequently.
1054 * Added additional information to EXITWITHTIMEOUT and EXITWITHKEY events in the
1056 * Added ability for non-realtime queues to have realtime members
1057 * Added the "linear" strategy to queues.
1058 * Added the "wrandom" strategy to queues.
1059 * Added new channel variable QUEUE_MIN_PENALTY
1060 * QUEUE_MAX_PENALTY and QUEUE_MIN_PENALTY may be adjusted in mid-call by defining
1061 rules in queuerules.conf. See configs/queuerules.conf.sample for details
1062 * Added a new parameter for member definition, called state_interface. This may be
1063 used so that a member may be called via one interface but have a different interface's
1064 device state reported.
1065 * Added new CLI and Manager commands relating to reloading queues. From the CLI, see
1066 "queue reload", "queue reset stats". Also see "manager show command QueueReload" and
1067 "manager show command QueueReset."
1068 * New configuration option: randomperiodicannounce. If a list of periodic announcements is
1069 specified by the periodic-announce option, then one will be chosen randomly when it is time
1070 to play a periodic announcment
1071 * New configuration options: announce-position now takes two more values in addition to "yes" and
1072 "no." Two new options, "limit" and "more," are allowed. These are tied to another option,
1073 announce-position-limit. By setting announce-position to "limit" callers will only have their
1074 position announced if their position is less than what is specified by announce-position-limit.
1075 If announce-position is set to "more" then callers beyond the position specified by announce-position-limit
1076 will be told that their are more than announce-position-limit callers waiting.
1077 * Two new queue log events have been added. An ADDMEMBER event will be logged
1078 when a realtime queue member is added and a REMOVEMEMBER event will be logged
1079 when a realtime queue member is removed. Since there is no calling channel associated
1080 with these events, the string "REALTIME" is placed where the channel's unique id
1081 is typically placed.
1082 * The configuration method for the "joinempty" and "leavewhenempty" options has
1083 changed to a comma-separated list of methods of determining member availability
1084 instead of vague terms such as "yes," "loose," "no," and "strict." These old four
1085 values are still accepted for backwards-compatibility, though.
1086 * The average talktime is now calculated on queues. This information is reported via the
1087 CLI commands "queue show" and "queues show"; through the AMI events AgentComplete, QueueSummary,
1088 and QueueParams; and through the channelvariable QUEUETALKTIME if setinterfacevar=yes is set for
1093 * The 'o' option to provide an optimization has been removed and its functionality
1094 has been enabled by default.
1095 * When a conference is created, the UNIQUEID of the channel that caused it to be
1096 created is stored. Then, every channel that joins the conference will have the
1097 MEETMEUNIQUEID channel variable set with this ID. This can be used to relate
1098 callers that come and go from long standing conferences.
1099 * Added a new application, MeetMeChannelAdmin, which is similar to MeetMeAdmin,
1100 except it does operations on a channel by name, instead of number in a conference.
1101 This is a very useful feature in combination with the 'X' option to ChanSpy.
1102 * Added 'C' option to Meetme which causes a caller to continue in the dialplan
1104 * Added new RealTime functionality to provide support for scheduled conferencing.
1105 This includes optional messages to the caller if they attempt to join before
1106 the schedule start time, or to allow the caller to join the conference early.
1107 Also included is optional support for limiting the number of callers per
1108 RealTime conference.
1109 * Added the S() and L() options to the MeetMe application. These are pretty
1110 much identical to the S() and L() options to Dial(). They let you set
1111 timeouts for the conference, as well as have warning sounds played to
1112 let the caller know how much time is left, and when it is running out.
1113 * Added the ability to do "meetme concise" with the "meetme" CLI command.
1114 This extends the concise capabilities of this CLI command to include
1115 listing all conferences, instead of an addition to the other sub commands
1116 for the "meetme" command.
1117 * Added the ability to specify the music on hold class used to play into the
1118 conference when there is only one member and the M option is used.
1119 * Added MEETME_INFO dialplan function which provides a way to query
1120 various properties of a Meetme conference.
1122 Other Dialplan Application Changes
1123 ----------------------------------
1124 * Argument support for Gosub application
1125 * From the to-do lists: straighten out the app timeout args:
1126 Wait() app now really does 0.3 seconds- was truncating arg to an int.
1127 WaitExten() same as Wait().
1128 Congestion() - Now takes floating pt. argument.
1129 Busy() - now takes floating pt. argument.
1130 Read() - timeout now can be floating pt.
1131 WaitForRing() now takes floating pt timeout arg.
1132 SpeechBackground() -- clarified in the docstrings that the timeout is an integer seconds.
1133 * Added 's' option to Page application.
1134 * Added an optional timeout argument to the Page application.
1135 * Added 'E', 'V', and 'P' commands to ExternalIVR.
1136 * Added 'o' and 'X' options to Chanspy.
1137 * Added a new dialplan application, Bridge, which allows you to bridge the
1138 calling channel to any other active channel on the system.
1139 * Added the ability to specify a music on hold class to play instead of ringing
1140 for the SLATrunk application.
1141 * The Read application no longer exits the dialplan on error. Instead, it sets
1142 READSTATUS to ERROR, which you can catch and handle separately.
1143 * Added 'm' option to Directory, which lists out names, 8 at a time, instead
1144 of asking for verification of each name, one at a time.
1145 * Privacy() no longer uses privacy.conf, as all options are specifyable as
1146 direct options to the app.
1147 * AMD() has a new "maximum word length" option. "show application AMD" from the CLI
1149 * GotoIfTime() now may branch based on a "false" condition, like other Goto-related applications
1150 * The ChannelRedirect application no longer exits the dialplan if the given channel
1151 does not exist. It will now set the CHANNELREDIRECT_STATUS variable to SUCCESS upon success
1152 or NOCHANNEL if the given channel was not found.
1153 * The silencethreshold setting that was previously configurable in multiple
1154 applications is now settable globally via dsp.conf.
1156 Music On Hold Changes
1157 ---------------------
1158 * A new option, "digit", has been added for music on hold classes in
1159 musiconhold.conf. If this is set for a music on hold class, a caller
1160 listening to music on hold can press this digit to switch to listening
1161 to this music on hold class.
1162 * Support for realtime music on hold has been added.
1163 * In conjunction with the realtime music on hold, a general section has
1164 been added to musiconhold.conf, its sole variable is cachertclasses. If this
1165 is set, then music on hold classes found in realtime will be cached in memory.
1169 * AEL upgraded to use the Gosub with Arguments instead
1170 of Macro application, to hopefully reduce the problems
1171 seen with the artificially low stack ceiling that
1172 Macro bumps into. Macros can only call other Macros
1173 to a depth of 7. Tests run using gosub, show depths
1174 limited only by virtual memory. A small test demonstrated
1175 recursive call depths of 100,000 without problems.
1176 -- in addition to this, all apps that allowed a macro
1177 to be called, as in Dial, queues, etc, are now allowing
1178 a gosub call in similar fashion.
1179 * AEL now generates LOCAL(argname) declarations when it
1180 Set()'s the each arg name to the value of ${ARG1}, ${ARG2),
1181 etc. That makes the arguments local in scope. The user
1182 can define their own local variables in macros, now,
1183 by saying "local myvar=someval;" or using Set() in this
1184 fashion: Set(LOCAL(myvar)=someval); ("local" is now
1186 * utils/conf2ael introduced. Will convert an extensions.conf
1187 file into extensions.ael. Very crude and unfinished, but
1188 will be improved as time goes by. Should be useful for a
1189 first pass at conversion.
1190 * aelparse will now read extensions.conf to see if a referenced
1191 macro or context is there before issueing a warning.
1192 * AEL parser sets a local channel variable ~~EXTEN~~, to
1193 preserve the value of ${EXTEN} thru switch statements.
1194 * New operator in $[...] expressions: the ~~ operator serves
1195 as a concatenation operator. AT THE MOMENT, it is really only
1196 necessary and useful in AEL, especially in if() expressions.
1197 Operation: ${a} ~~ ${b| with force both a and b to strings, strip
1198 any enclosing double-quotes, and evaluate to the value of a
1199 concatenated with the value of b. For example if a is set to
1200 "xyz" and b has the value "abc", then ${a} ~~ ${b| would
1201 evaluate to xyzabc .
1204 Call Features (res_features) Changes
1205 ------------------------------------
1206 * Added the parkedcalltransfers option to features.conf
1207 * Added parkedcallparking option to control one touch parking w/ parking
1209 * Added parkedcallhangup option to control disconnect feature w/ parking
1211 * Added parkedcallrecording option to control one-touch record w/ parking
1213 * Added BRIDGE_FEATURES variable to set available features for a channel
1214 * The built-in method for doing attended transfers has been updated to
1215 include some new options that allow you to have the transferee sent
1216 back to the person that did the transfer if the transfer is not successful.
1217 See the options "atxferdropcall", "atxferloopdelay", and "atxfercallbackretries"
1218 in features.conf.sample.
1219 * Added support for configuring named groups of custom call features in
1220 features.conf. This means that features can be written a single time, and
1221 then mapped into groups of features for different key mappings or easier
1223 * Updated the ParkedCall application to allow you to not specify a parking
1224 extension. If you don't specify a parking space to pick up, it will grab
1225 the first one available.
1226 * Added cli command 'features reload' to reload call features from features.conf
1227 * Moved into core asterisk binary.
1228 * Changed the default setting for featuredigittimeout to 2000 ms from 500 ms.
1230 Language Support Changes
1231 ------------------------
1232 * Brazilian Portuguese (pt-BR) in VM, and say.c was added
1233 * Added support for the Hungarian language for saying numbers, dates, and times.
1237 * Added SPEECH commands for speech recognition. A complete listing can be found
1239 * If app_stack is loaded, GOSUB is a native AGI command that may be used to
1240 invoke subroutines in the dialplan. Note that calling EXEC with Gosub
1241 does not behave as expected; the native command needs to be used, instead.
1245 * Added rotatestrategy option to logger.conf, along with two new options:
1246 "timestamp" which will use the time to name the logger files instead of
1247 sequence number; and "rotate", which rotates the names of the log files,
1248 similar to the way syslog rotates files.
1249 * Added exec_after_rotate option to logger.conf, which allows a system
1250 command to be run after rotation. This is primarily useful with
1251 rotatestrategy=rotate, to allow a limit on the number of log files kept
1252 and to ensure that the oldest log file gets deleted.
1253 * Added realtime support for the queue log
1257 * The cdr_manager module has a [mappings] feature, like cdr_custom,
1258 to add fields to the manager event from the CDR variables.
1259 * Added cdr_adaptive_odbc, a new module that adapts to the structure of your
1260 backend database CDR table. Specifically, additional, non-standard
1261 columns are supported, merely by setting the corresponding CDR variable in
1262 your dialplan. In addition, you may alias any column to another name (for
1263 example, if you want the 'src' CDR variable to be column 'ANI' in the DB,
1264 simply "alias src => ANI" in the configuration file). Records may be
1265 posted to more than one backend, simply by specifying multiple categories
1266 in the configuration file. And finally, you may filter which CDRs get
1267 posted to each backend, by specifying a filter (which the record must
1268 match) for the particular category. Filters are additive (meaning all
1269 rules must match to post that CDR).
1270 * The Postgres CDR module now supports some features of the cdr_adaptive_odbc
1271 module. Specifically, you may add additional columns into the table and
1272 they will be set, if you set the corresponding CDR variable name. Also,
1273 if you omit columns in your database table, they will be silently skipped
1274 (but a record will still be inserted, based on what columns remain). Note
1275 that the other two features from cdr_adaptive_odbc (alias and filter) are
1276 not currently supported.
1277 * The ResetCDR application now has an 'e' option that re-enables a CDR if it
1278 has been disabled using the NoCDR application.
1280 Miscellaneous New Modules
1281 -------------------------
1282 * Added a new CDR module, cdr_sqlite3_custom.
1283 * Added a new realtime configuration module, res_config_sqlite
1284 * Added a new codec translation module, codec_resample, which re-samples
1285 signed linear audio between 8 kHz and 16 kHz to help support wideband
1287 * Added a new module, res_phoneprov, which allows auto-provisioning of phones
1288 based on configuration templates that use Asterisk dialplan function and
1289 variable substitution. It should be possible to create phone profiles and
1290 templates that work for the majority of phones provisioned over http. It
1291 is currently only intended to provision a single user account per phone.
1292 An example profile and set of templates for Polycom phones is provided.
1293 NOTE: Polycom firmware is not included, but should be placed in
1294 AST_DATA_DIR/phoneprov/configs to match up with the included templates.
1295 * Added a new module, app_jack, which provides interfaces to JACK, the Jack
1296 Audio Connection Kit (http://www.jackaudio.org/). Two interfaces are
1297 provided; there is a JACK() application, and a JACK_HOOK() function. Both
1298 interfaces create an input and output JACK port. The application makes
1299 these ports the endpoint of the call. The audio coming from the channel
1300 goes out the output port and whatever comes back in on the input port is
1301 what gets sent to the channel. The JACK_HOOK() function turns on a JACK
1302 audiohook on the channel. This lets you run the audio coming from a
1303 channel through JACK, and whatever comes back in is what gets forwarded
1304 on as the channel's audio. This is very useful for building custom
1305 vocoders or doing recording or analysis of the channel's audio in another
1307 * Added a new module, res_config_curl, which permits using a HTTP POST url
1308 to retrieve, create, update, and delete realtime information from a remote
1309 web server. Note that this module requires func_curl.so to be loaded for
1310 backend functionality.
1311 * Added a new module, res_config_ldap, which permits the use of an LDAP
1312 server for realtime data access.
1313 * Added support for writing and running your dialplan in lua using the pbx_lua
1314 module. See configs/extensions.lua.sample for examples of how to do this.
1318 * Ability to use libcap to set high ToS bits when non-root
1319 on Linux. If configure is unable to find libcap then you
1320 can use --with-cap to specify the path.
1321 * Added maxfiles option to options section of asterisk.conf which allows you to specify
1322 what Asterisk should set as the maximum number of open files when it loads.
1323 * Added the jittertargetextra configuration option.
1324 * Added support for setting the CoS for VLAN traffic (802.1p). See the sample
1325 configuration files for the IP channel drivers. The new option is "cos".
1326 This information is also documented in doc/qos.tex, or the IP Quality of Service
1327 section of asterisk.pdf.
1328 * When originating a call using AMI or pbx_spool that fails the reason for failure
1329 will now be available in the failed extension using the REASON dialplan variable.
1330 * Added support for reading the TOUCH_MONITOR_PREFIX channel variable.
1331 It allows you to configure a prefix for auto-monitor recordings.
1332 * A new extension pattern matching algorithm, based on a trie, is introduced
1333 here, that could noticeably speed up mid-sized to large dialplans.
1334 It is NOT used by default, as duplicating the behaviour of the old pattern
1335 matcher is still under development. A config file option, in extensions.conf,
1336 in the [general] section, called "extenpatternmatchingnew", is by default
1337 set to false; setting that to true will force the use of the new algorithm.
1338 Also, the cli commands "dialplan set extenpatternmatchingnew true/false" can
1339 be used to switch the algorithms at run time.
1340 * A new option when starting a remote asterisk (rasterisk, asterisk -r) for
1341 specifying which socket to use to connect to the running Asterisk daemon
1343 * Performance enhancements to the sched facility, which is used in
1344 the channel drivers, etc. Added hashtabs and doubly-linked lists
1345 to speed up deletion; start at the beginning or end of list to
1347 * Added Doubly-linked lists after the fashion of linkedlists.h. They are in
1348 dlinkedlists.h. Doubly-linked lists feature fast deletion times.
1349 Added regression tests to the tests/ dir, also.
1350 * Added a refcount trace feature to astobj2 for those trying to balance
1351 object creation, deletion; work, play; space and time. See the
1352 notes in astobj2.h. Also, see utils/refcounter as well, as a
1353 quick way to find unbalanced refcounts in what could be a sea
1354 of objects that were balanced.
1355 * Added logging to 'make update' command. See update.log
1356 * Added strictrtp option to rtp.conf. If enabled this will drop RTP packets that
1357 do not come from the remote party.
1358 * Added the 'n' option to the SpeechBackground application to tell it to not
1359 answer the channel if it has not already been answered.
1360 * Added a compiler flag, CHANNEL_TRACE, which permits channel tracing to be
1361 turned on, via the CHANNEL(trace) dialplan function. Could be useful for
1363 * iLBC source code no longer included (see UPGRADE.txt for details)
1364 * If compiled with DETECT_DEADLOCKS enabled and if you have glibc, then if
1365 deadlock is detected, a backtrace of the stack which led to the lock calls
1366 will be output to the CLI.
1367 * If compiled with DEBUG_THREADS enabled and if you have glibc, then issuing
1368 the "core show locks" CLI command will give lock information output as well
1369 as a backtrace of the stack which led to the lock calls.
1370 * users.conf now sports an optional alternateexts property, which permits
1371 allocation of additional extensions which will reach the specified user.
1372 * A new option for the configure script, --enable-internal-poll, has been added
1373 for use with systems which may have a buggy implementation of the poll system
1374 call. If you notice odd behavior such as the CLI being unresponsive on remote
1375 consoles, you may want to try using this option. This option is enabled by default
1376 on Darwin systems since it is known that the Darwin poll() implementation has
1380 --------------------
1381 * In addition to timing from DAHDI, there is a new timing module called
1382 res_timing_timerfd. In order to use this, you must be running Linux with
1383 a kernel version 2.6.25 or newer as well as glibc 2.8 or newer. The configure
1384 script will be able to tell if you have the requirements. From menuselect, select
1385 res_timing_timerfd from the Resource Modules menu.
