1 ------------------------------------------------------------------------------
2 --- Functionality changes from Asterisk 1.6.1 to Asterisk 1.6.2 -------------
3 ------------------------------------------------------------------------------
7 * Added a new dialplan function, CURLOPT, which permits setting various
8 options that may be useful with the CURL dialplan function, such as
9 cookies, proxies, connection timeouts, passwords, etc.
11 ------------------------------------------------------------------------------
12 --- Functionality changes from Asterisk 1.6.0 to Asterisk 1.6.1 -------------
13 ------------------------------------------------------------------------------
17 * The event infrastructure in Asterisk got another big update to help support
18 distributed events. It currently supports distributed device state and
19 distributed Voicemail MWI (Message Waiting Indication). A new module has
20 been merged, res_ais, which facilitates communicating events between servers.
21 It uses the SAForum AIS (Service Availability Forum Application Interface
22 Specification) CLM (Cluster Management) and EVT (Event) services to maintain
23 a cluster of Asterisk servers, and to share events between them. For more
24 information on setting this up, see doc/distributed_devstate.txt.
28 * Added a new dialplan function, AST_CONFIG(), which allows you to access
29 variables from an Asterisk configuration file.
30 * The JACK_HOOK function now has a c() option to supply a custom client name.
31 * Added two new dialplan functions from libspeex for audio gain control and
32 denoise, AGC() and DENOISE(). Both functions can be applied to the tx and
33 rx directions of a channel from the dialplan.
34 * The SMDI_MSG_RETRIEVE function now has the ability to search for SMDI messages
35 based on other parameters. The default is still to search based on the
36 forwarding station ID. However, there are new options that allow you to search
37 based on the message desk terminal ID, or the message desk number.
38 * TIMEOUT() has been modified to be accurate down to the millisecond.
39 * ENUM*() functions now include the following new options:
40 - 'u' returns the full URI and does not strip off the URI-scheme.
41 - 's' triggers ISN specific rewriting
42 - 'i' looks for branches into an Infrastructure ENUM tree
43 - 'd' for a direct DNS lookup without any flipping of digits.
44 * TXCIDNAME() has a new zone-suffix parameter (which defaults to 'e164.arpa')
45 * CHANNEL() now has options for the maximum, minimum, and standard or normal
46 deviation of jitter, rtt, and loss for a call using chan_sip.
48 DAHDI channel driver (chan_dahdi) Changes
49 ----------------------------------------
50 * Channels can now be configured using named sections in chan_dahdi.conf, just
51 like other channel drivers, including the use of templates.
52 * The default for pridialplan has changed from 'national' to 'unknown'.
56 * It is now possible to specify a pattern match as a hint. Once a phone subscribes
57 to something that matches the pattern a hint will be created using the contents
58 and variables evaluated.
59 * Dialplan matching has been extended to allow an extension to return to the
60 PBX core to wait for more digits. This is done by using the new dialplan
61 application called "Incomplete". This will permit a whole new level of
62 extension control, by giving the administrator more control over early
63 matches employing one of the short-circuit pattern match operators. Note
64 that custom applications can trigger this same behavior by returning the
65 special value AST_PBX_INCOMPLETE.
69 * Directory now permits both first and last names to be matched at the same
70 time. In addition, the number of digits to enter of the name can be set in
71 the arguments to Directory; previously, you could enter only 3, regardless
72 of how many names are in your company. For large companies, this should be
74 * Voicemail now permits a mailbox setting to wrap around from first to last
75 messages, if the "messagewrap" option is set to a true value.
76 * Voicemail now permits an external script to be run, for password validation.
77 The script should output "VALID" or "INVALID" on stdout, depending upon the
78 wish to validate or invalidate the password given. Arguments are:
79 "mailbox" "context" "oldpass" "newpass". See the sample voicemail.conf for
81 * Dial has a new option: F(context^extension^pri), which permits a callee to
82 continue in the dialplan, at the specified label, if the caller hangs up.
83 * ChanSpy and ExtenSpy have a new option, 's' which suppresses speaking the
84 technology name (e.g. SIP, IAX, etc) of the channel being spied on.
85 * The Jack application now has a c() option to supply a custom client name.
86 * Chanspy has a new option, 'B', which can be used to "barge" on a call. This is
87 like the pre-existing whisper mode, except that the spy can also talk to the
88 participant on the bridged channel as well.
89 * Chanspy has a new option, 'n', which will allow for the spied-on party's name
90 to be spoken instead of the channel name or number. For more information on the
91 use of this option, issue the command "core show application ChanSpy" from the
93 * Chanspy has a new option, 'd', which allows the spy to use DTMF to swap between
94 spy modes. Use of this feature overrides the typical use of numeric DTMF. In other
95 words, if using the 'd' option, it is not possible to enter a number to append to
96 the first argument to Chanspy(). Pressing 4 will change to spy mode, pressing 5 will
97 change to whisper mode, and pressing 6 will change to barge mode.
98 * ExternalIVR now takes several options that affect the way it performs, as
99 well as having several new commands. Please see doc/externalivr.txt for the
100 complete documentation.
101 * ChanIsAvail has a new option, 'a', which will return all available channels instead
102 of just the first one if you give the function more then one channel to check.
103 * PrivacyManager now takes an option where you can specify a context where the
104 given number will be matched. This way you have more control over who is allowed
105 and it stops the people who blindly enter 10 digits.
106 * ForkCDR has new options: 'a' updates the answer time on the new CDR; 'A' locks
107 answer times, disposition, on orig CDR against updates; 'D' Copies the disposition
108 from the orig CDR to the new CDR after reset; 'e' sets the 'end' time on the
109 original CDR; 'R' prevents the new CDR from being reset; 's(var=val)' adds/changes
110 the 'var' variable on the original CDR; 'T' forces ast_cdr_end(), ast_cdr_answer(),
111 obey the LOCKED flag on cdr's in the chain, and also the ast_cdr_setvar() func.
112 * The Dial() application no longer copies the language used by the caller to the callee's
113 channel. If you desire for the caller's channel's language to be used for file playback
114 to the callee, then the file specified may be prepended with "${CHANNEL(language)}/" .
115 * SendImage() no longer hangs up the channel on error; instead, it sets the
116 status variable SENDIMAGESTATUS to one of 'SUCCESS', 'FAILURE', or
117 'UNSUPPORTED'. This change makes SendImage() more consistent with other
119 * Park has a new option, 's', which silences the announcement of the parking space number.
123 * Added DNS manager support to registrations for peers referencing peer entries.
124 DNS manager runs in the background which allows DNS lookups to be run asynchronously
125 as well as periodically updating the IP address. These properties allow for
126 better performance as well as recovery in the event of an IP change.
127 * Performance improvements via using hash tables (astobj2) and doubly-linked lists to improve
128 load/reload of large numbers of peers/users by ~40x (for large lists of peers.
129 Initially, we saw 4x improvement in call setup/destruction, but at the time
130 of merging, this gain has disappeared; further research will be done to try
131 and restore this performance improvement. Astobj2 refcounting is now used
132 for users, peers, and dialogs. Users are encouraged to assist in regression
133 testing and problem reporting!
134 * Added ability to specify registration expiry time on a per registration basis in
136 * Added support for T140 RED - redundancy in T.140 to prevent text loss due to
138 * Added t38pt_usertpsource option. See sip.conf.sample for details.
139 * Added SIPnotify AMI command, for sending arbitrary SIP notify commands.
140 * 'sip show peers' and 'sip show users' display their entries sorted in
141 alphabetical order, as opposed to the order they were in, in the config
143 * Videosupport now supports an additional option, "always", which always sets
144 up video RTP ports, even on clients that don't support it. This helps with
145 callfiles and certain transfers to ensure that if two video phones are
146 connected, they will always share video feeds.
150 * Existing DNS manager lookups extended to check for SRV records.
151 * IAX2 encryption support has been improved to support periodic key rotation
152 within a call for enhanced security. The option "keyrotate" has been
153 provided to disable this functionality to preserve backwards compatibility
154 with older versions of IAX2 that do not support key rotation.
158 * New CLI command, "config reload <file.conf>" which reloads any module that
159 references that particular configuration file. Also added "config list"
160 which shows which configuration files are in use.
161 * New CLI commands, "pri show version" and "ss7 show version" that will
162 display which version of libpri and libss7 are being used, respectively.
163 A new API call was added so trunk will now have to be compiled against
164 a versions of libpri and libss7 that have them or it will not know that
165 these libraries exist.
166 * The commands "core show globals", "core set global" and "core set chanvar" has
167 been deprecated in favor of the more semanticly correct "dialplan show globals",
168 "dialplan set chanvar" and "dialplan set global".
169 * New CLI command "dialplan show chanvar" to list all variables associated
170 with a given channel.
174 * Addresses managed by DNS manager now can check to see if there is a DNS
175 SRV record for a given domain and will use that hostname/port if present.
177 AMI - The manager (TCP/TLS/HTTP)
178 --------------------------------
179 * The Status command now takes an optional list of variables to display
180 along with channel status.
184 * res_odbc no longer has a limit of 1023 total possible unshared connections,
185 as some people were running into this limit. This limit has been increased
190 * The TRANSFER queue log entry now includes the the caller's original
191 position in the transferred-from queue.
192 * A new configuration option, "timeoutpriority" has been added. Please see the section labeled
193 "QUEUE TIMING OPTIONS" in configs/queues.conf.sample for a detailed explanation of the option
194 as well as an explanation about timeout options in general
198 * Several (ODBC, Postgres, MySQL, SQLite) realtime drivers have been given
199 adaptive capabilities. What this means in practical terms is that if your
200 realtime table lacks critical fields, Asterisk will now emit warnings to
201 that effect. Also, some of the realtime drivers have the ability (if
202 configured) to automatically add those columns to the table with the
203 correct type and length.
207 * The channel variable ATTENDED_TRANSFER_COMPLETE_SOUND can now be set using
208 the 'setvar' option to cause a given audio file to be played upon completion
209 of an attended transfer. Currently it works for DAHDI, IAX2, SIP, and
210 Skinny channels only.
211 * You can now compile Asterisk against the Hoard Memory Allocator, see doc/hoard.txt
212 for more information.
213 * Config file variables may now be appended to, by using the '+=' append
214 operator. This is most helpful when working with long SQL queries in
215 func_odbc.conf, as the queries no longer need to be specified on a single
217 * CDR config file, cdr.conf, has an added option, "initiatedseconds",
218 which will add a second to the billsec when the ending
219 time is set, if the number in the microseconds field of the end time is
220 greater than the number of microseconds in the answer time. This allows
221 users to count the 'initiated' seconds in their billing records.
223 ------------------------------------------------------------------------------
224 --- Functionality changes from Asterisk 1.4.X to Asterisk 1.6.0 -------------
225 ------------------------------------------------------------------------------
227 AMI - The manager (TCP/TLS/HTTP)
228 --------------------------------
229 * Manager has undergone a lot of changes, all of them documented
230 in doc/manager_1_1.txt
231 * Manager version has changed to 1.1
232 * Added a new action 'CoreShowChannels' to list currently defined channels
233 and some information about them.
234 * Added a new action 'SIPshowregistry' to list SIP registrations.
235 * Added TLS support for the manager interface and HTTP server
236 * Added the URI redirect option for the built-in HTTP server
237 * The output of CallerID in Manager events is now more consistent.
238 CallerIDNum is used for number and CallerIDName for name.
239 * Enable https support for builtin web server.
240 See configs/http.conf.sample for details.
241 * Added a new action, GetConfigJSON, which can return the contents of an
242 Asterisk configuration file in JSON format. This is intended to help
243 improve the performance of AJAX applications using the manager interface
245 * SIP and IAX manager events now use "ChannelType" in all cases where we
246 indicate channel driver. Previously, we used a mixture of "Channel"
247 and "ChannelDriver" headers.
248 * Added a "Bridge" action which allows you to bridge any two channels that
249 are currently active on the system.
250 * Added a "ListAllVoicemailUsers" action that allows you to get a list of all
251 the voicemail users setup.
252 * Added 'DBDel' and 'DBDelTree' manager commands.
253 * cdr_manager now reports events via the "cdr" level, separating it from
254 the very verbose "call" level.
255 * Manager users are now stored in memory. If you change the manager account
256 list (delete or add accounts) you need to reload manager.
257 * Added Masquerade manager event for when a masquerade happens between
259 * Added "manager reload" command for the CLI
260 * Lots of commands that only provided information are now allowed under the
261 Reporting privilege, instead of only under Call or System.
262 * The IAX* commands now require either System or Reporting privilege, to
263 mirror the privileges of the SIP* commands.
264 * Added ability to retrieve list of categories in a config file.
265 * Added ability to retrieve the content of a particular category.
266 * Added ability to empty a context.
267 * Created new action to create a new file.
268 * Updated delete action to allow deletion by line number with respect to category.
269 * Added new action insert to add new variable to category at specified line.
270 * Updated action newcat to allow new category to be inserted in file above another
272 * Added new event "JitterBufStats" in the IAX2 channel
273 * Originate now requires the Originate privilege and, if you want to call out
274 to a subshell, it requires the System privilege, as well. This was done to
275 enhance manager security.
276 * Originate now accepts codec settings with "Codecs: alaw, ulaw, h264"
277 * New command: Atxfer. See doc/manager_1_1.txt for more details or
278 manager show command Atxfer from the CLI
282 * Added the DEVICE_STATE() dialplan function which allows retrieving any device
283 state in the dialplan, as well as creating custom device states that are
284 controllable from the dialplan.
285 * Extend CALLERID() function with "pres" and "ton" parameters to
286 fetch string representation of calling number presentation indicator
287 and numeric representation of type of calling number value.
288 * MailboxExists converted to dialplan function
289 * A new option to Dial() for telling IP phones not to count the call
290 as "missed" when dial times out and cancels.
291 * Added LOCK(), TRYLOCK(), and UNLOCK(), which provide a single level dialplan
292 mutex. No deadlocks are possible, as LOCK() only allows a single lock to be
293 held for any given channel. Also, locks are automatically freed when a
295 * Added HINT() dialplan function that allows retrieving hint information.
296 Hints are mappings between extensions and devices for the sake of
297 determining the state of an extension. This function can retrieve the list
298 of devices or the name associated with a hint.
299 * Added EXTENSION_STATE() dialplan function which allows retrieving the state
301 * Added SYSINFO() dialplan function which allows retrieval of system information
302 * Added a new dialplan function, DIALPLAN_EXISTS(), which allows you to check for
303 the existence of a dialplan target.
304 * Added two new dialplan functions, TOUPPER and TOLOWER, which convert a string to
305 upper and lower case, respectively.
306 * When bridging, Asterisk sets the BRIDGEPVTCALLID to the channel drivers unique
307 ID for the call (not the Asterisk call ID or unique ID), provided that the
308 channel driver supports this. For SIP, you get the SIP call-ID for the
309 bridged channel which you can store in the CDR with a custom field.
313 * New CLI command "core show hint" (usage: core show hint <exten>)
314 * New CLI command "core show settings"
315 * Added 'core show channels count' CLI command.
316 * Added the ability to set the core debug and verbose values on a per-file basis.
317 * Added 'queue pause member' and 'queue unpause member' CLI commands
318 * Ability to set process limits ("ulimit") without restarting Asterisk
319 * Enhanced "agi debug" to print the channel name as a prefix to the debug
320 output to make debugging on busy systems much easier.
321 * New CLI commands "dialplan set extenpatternmatching true/false"
322 * New CLI command: "core set chanvar" to set a channel variable from the CLI.
323 * Added an easy way to execute Asterisk CLI commands at startup. Any commands
324 listed in the startup_commands section of cli.conf will get executed.
325 * Added a CLI command, "devstate change", which allows you to set custom device
326 states from the func_devstate module that provides the DEVICE_STATE() function
327 and handling of the "Custom:" devices.
328 * New CLI command: "sip show sched" which shows all ast_sched entries for sip,
329 sorted into the different possible callbacks, with the number of entries
330 currently scheduled for each. Gives you a feel for how busy the sip channel
332 * Added 'skinny show lines verbose' CLI command. This will show the subs for every channel.
336 * Improved NAT and STUN support.
337 chan_sip now can use port numbers in bindaddr, externip and externhost
338 options, as well as contact a STUN server to detect its external address
339 for the SIP socket. See sip.conf.sample, 'NAT' section.
340 * The default SIP useragent= identifier now includes the Asterisk version
341 * A new option, match_auth_username in sip.conf changes the matching of incoming requests.
342 If set, and the incoming request carries authentication info,
343 the username to match in the users list is taken from the Digest header
344 rather than from the From: field. This feature is considered experimental.
345 * The "musiconhold" and "musicclass" settings in sip.conf are now removed,
346 since they where replaced by "mohsuggest" and "mohinterpret" in version 1.4
347 * The "localmask" setting was removed in version 1.2 and the reminder about it
348 being removed is now also removed.
349 * A new option "busylevel" for setting a level of calls where asterisk reports
350 a device as busy, to separate it from call-limit. This value is also added
351 to the SIP_PEER dialplan function.
352 * A new realtime family called "sipregs" is now supported to store SIP registration
353 data. If this family is defined, "sippeers" will be used for configuration and
354 "sipregs" for registrations. If it's not defined, "sippeers" will be used for
355 registration data, as before.
356 * The SIPPEER function have new options for port address, call and pickup groups
357 * Added support for T.140 realtime text in SIP/RTP
358 * The "checkmwi" option has been removed from sip.conf, as it is no longer
359 required due to the restructuring of how MWI is handled. See the descriptions
360 in this file of the "pollmailboxes" and "pollfreq" options to voicemail.conf
361 for more information.
362 * Added rtpdest option to CHANNEL() dialplan function.
363 * Added SIPREFERRINGCONTEXT and SIPREFERREDBYHDR variables which are set when a transfer takes place.
364 * SIP now adds a header to the CANCEL if the call was answered by another phone
365 in the same dial command, or if the new c option in dial() is used.
366 * The new default is that 100 Trying is not sent on REGISTER attempts as the RFC specifically
367 states it is not needed. For phones, however, that do require it the "registertrying" option
368 has been added so it can be enabled.
369 * A new option called "callcounter" (global/peer/user level) enables call counters needed
370 for better status reports needed for queues and SIP subscriptions. (Call-Limit was previously
371 used to enable this functionality).
372 * New settings for timer T1 and timer B on a global level or per device. This makes it
373 possible to force timeout faster on non-responsive SIP servers. These settings are
374 considered advanced, so don't use them unless you have a problem.
375 * Added a dial string option to be able to set the To: header in an INVITE to any
377 * Added a new global and per-peer option, qualifyfreq, which allows you to configure
378 the qualify frequency.
379 * Added SIP Session Timers support (RFC 4028). This prevents stuck SIP sessions that
380 were not properly torn down due to network or endpoint failures during an established
382 * Added experimental TCP and TLS support for SIP. See doc/siptls.txt and
383 configs/sip.conf.sample for more information on how it is used.
384 * Added a new configuration option "authfailureevents" that enables manager events when
385 a peer can't authenticate properly.
386 * Added DNS manager support to registrations for peers not referencing a peer entry.
390 * Added the trunkmaxsize configuration option to chan_iax2.
391 * Added the srvlookup option to iax.conf
392 * Added support for OSP. The token is set and retrieved through the CHANNEL()
395 XMPP Google Talk/Jingle changes
396 -------------------------------
397 * Added the bindaddr option to gtalk.conf.
401 * Added skinny show device, skinny show line, and skinny show settings CLI commands.
402 * Proper codec support in chan_skinny.
403 * Added settings for IP and Ethernet QoS requests
407 * Added separate settings for media QoS in mgcp.conf
409 Console Channel Driver changes
410 ------------------------------
411 * Added experimental support for video send & receive to chan_oss.
412 This requires SDL and ffmpeg/avcodec, plus Video4Linux or X11 to act as
415 Phone channel changes (chan_phone)
416 ----------------------------------
417 * Added G729 passthrough support to chan_phone for Sigma Designs boards.
419 H.323 channel Changes
420 ---------------------
421 * H323 remote hold notification support added (by NOTIFY message
422 and/or H.450 supplementary service)
424 Local channel changes
425 ---------------------
426 * The device state functionality in the Local channel driver has been updated
427 to indicate INUSE or NOT_INUSE when a Local channel is being used as opposed
428 to just UNKNOWN if the extension exists.
429 * Added jitterbuffer support for chan_local. This allows you to use the
430 generic jitterbuffer on incoming calls going to Asterisk applications.
431 For example, this would allow you to use a jitterbuffer for an incoming
432 SIP call to Voicemail by putting a Local channel in the middle. This
433 feature is enabled by using the 'j' option in the Dial string to the Local
434 channel in conjunction with the existing 'n' option for local channels.
435 * A 'b' option has been added which causes chan_local to return the actual channel
436 that is behind it when queried. This is useful for transfer scenarios as the
437 actual channel will be transferred, not the Local channel.
439 Agent channel changes
440 ----------------------
441 * The ackcall and endcall options are now supplemented with options acceptdtmf
442 and enddtmf. These allow for the DTMF keypress to be configurable. The options
443 default to their old hard-coded values ('#' and '*' respectively) so this should
444 not break any existing agent installations.
446 DAHDI channel driver (chan_dahdi) Changes
447 ----------------------------------------
448 * SS7 support (via libss7 library)
449 * In India, some carriers transmit CID via dtmf. Some code has been added
450 that will handle some situations. The cidstart=polarity_IN choice has been added for
451 those carriers that transmit CID via dtmf after a polarity change.
452 * CID matching information is now shown when doing 'dialplan show'.
453 * Added dahdi show version CLI command.
454 * Added setvar support to chan_dahdi.conf channel entries.
455 * Added two new options: mwimonitor and mwimonitornotify. These options allow
456 you to enable MWI monitoring on FXO lines. When the MWI state changes,
457 the script specified in the mwimonitornotify option is executed. An internal
458 event indicating the new state of the mailbox is also generated, so that
459 the normal MWI facilities in Asterisk work as usual.
460 * Added signalling type 'auto', which attempts to use the same signalling type
461 for a channel as configured in DAHDI. This is primarily designed for analog
462 ports, but will also work for digital ports that are configured for FXS or FXO
463 signalling types. This mode is also the default now, so if your chan_dahdi.conf
464 does not specify signalling for a channel (which is unlikely as the sample
465 configuration file has always recommended specifying it for every channel) then
466 the 'auto' mode will be used for that channel if possible.
467 * Added a 'dahdi set dnd' command to allow CLI control of the Do-Not-Disturb
468 state for a channel; also ensured that the DNDState Manager event is
469 emitted no matter how the DND state is set or cleared.
473 * Added a new channel driver, chan_unistim. See doc/unistim.txt and
474 configs/unistim.conf.sample for details. This new channel driver allows
475 you to use Nortel i2002, i2004, and i2050 phones with Asterisk.
476 * Added a new channel driver, chan_console, which uses portaudio as a cross
477 platform audio interface. It was written as a channel driver that would
478 work with Mac CoreAudio, but portaudio supports a number of other audio
479 interfaces, as well. Note that this channel driver requires v19 or higher
480 of portaudio; older versions have a different API.
484 * Added the ability to specify arguments to the Dial application when using
485 the DUNDi switch in the dialplan.
486 * Added the ability to set weights for responses dynamically. This can be
487 done using a global variable or a dialplan function. Using the SHELL()
488 function would allow you to have an external script set the weight for
490 * Added two new dialplan functions, DUNDIQUERY and DUNDIRESULT. These
491 functions will allow you to initiate a DUNDi query from the dialplan,
492 find out how many results there are, and access each one.
496 * Added two new dialplan functions, ENUMQUERY and ENUMRESULT. These
497 functions will allow you to initiate an ENUM lookup from the dialplan,
498 and Asterisk will cache the results. ENUMRESULT can be used to access
499 the results without doing multiple DNS queries.
503 * Added the ability to customize which sound files are used for some of the
504 prompts within the Voicemail application by changing them in voicemail.conf
505 * Added the ability for the "voicemail show users" CLI command to show users
506 configured by the dynamic realtime configuration method.
507 * MWI (Message Waiting Indication) handling has been significantly
508 restructured internally to Asterisk. It is now totally event based
509 instead of polling based. The voicemail application will notify other
510 modules that have subscribed to MWI events when something in the mailbox
512 This also means that if any other entity outside of Asterisk is changing
513 the contents of mailboxes, then the voicemail application still needs to
514 poll for changes. Examples of situations that would require this option
515 are web interfaces to voicemail or an email client in the case of using
516 IMAP storage. So, two new options have been added to voicemail.conf
517 to account for this: "pollmailboxes" and "pollfreq". See the sample
518 configuration file for details.
519 * Added "tw" language support
520 * Added support for storage of greetings using an IMAP server
521 * Added ability to customize forward, reverse, stop, and pause keys for message playback
522 * SMDI is now enabled in voicemail using the smdienable option.
523 * A "lockmode" option has been added to asterisk.conf to configure the file
524 locking method used for voicemail, and potentially other things in the
525 future. The default is the old behavior, lockfile. However, there is a
526 new method, "flock", that uses a different method for situations where the
527 lockfile will not work, such as on SMB/CIFS mounts.
528 * Added the ability to backup deleted messages, to ease recovery in the case
529 that a user accidentally deletes a message, and discovers that they need it.
530 * Reworked the SMDI interface in Asterisk. The new way to access SMDI information
531 is through the new functions, SMDI_MSG_RETRIEVE() and SMDI_MSG(). The file
532 smdi.conf can now be configured with options to map SMDI station IDs to Asterisk
533 voicemail boxes. The SMDI interface can also poll for MWI changes when some
534 outside entity is modifying the state of the mailbox (such as IMAP storage or
535 a web interface of some kind).
536 * Added the support for marking messages as "urgent." There are two methods to accomplish
537 this. One is to pass the 'U' option to VoiceMail(). Another way to mark a message as urgent
538 is to specify "review=yes" in voicemail.conf. Doing this will cause allow the user to mark
539 the message as urgent after he has recorded a voicemail by following the voice instructions.
540 When listening to voicemails using VoiceMailMain urgent messages will be presented before other
545 * Added the general option 'shared_lastcall' so that member's wrapuptime may be
546 used across multiple queues.
547 * Added QUEUE_VARIABLES function to set queue variables added setqueuevar and
548 setqueueentryvar options for each queue, see queues.conf.sample for details.
549 * Added keepstats option to queues.conf which will keep queue
550 statistics during a reload.
551 * setinterfacevar option in queues.conf also now sets a variable
552 called MEMBERNAME which contains the member's name.
553 * Added 'Strategy' field to manager event QueueParams which represents
554 the queue strategy in use.
555 * Added option to run macro when a queue member is connected to a caller,
556 see queues.conf.sample for details.
557 * app_queue now has a 'loose' option which is almost exactly like 'strict' except it
558 does not count paused queue members as unavailable.
559 * Added min-announce-frequency option to queues.conf which allows you to control the
560 minimum amount of time between queue announcements for use when the caller's queue
561 position changes frequently.
562 * Added additional information to EXITWITHTIMEOUT and EXITWITHKEY events in the
564 * Added ability for non-realtime queues to have realtime members
565 * Added the "linear" strategy to queues.
566 * Added the "wrandom" strategy to queues.
567 * Added new channel variable QUEUE_MIN_PENALTY
568 * QUEUE_MAX_PENALTY and QUEUE_MIN_PENALTY may be adjusted in mid-call by defining
569 rules in queuerules.conf. See configs/queuerules.conf.sample for details
570 * Added a new parameter for member definition, called state_interface. This may be
571 used so that a member may be called via one interface but have a different interface's
572 device state reported.
573 * New configuration option: randomperiodicannounce. If a list of periodic announcements is
574 specified by the periodic-announce option, then one will be chosen randomly when it is time
575 to play a periodic announcment
576 * New configuration options: announce-position now takes two more values in addition to "yes" and
577 "no." Two new options, "limit" and "more," are allowed. These are tied to another option,
578 announce-position-limit. By setting announce-position to "limit" callers will only have their
579 position announced if their position is less than what is specified by announce-position-limit.
580 If announce-position is set to "more" then callers beyond the position specified by announce-position-limit
581 will be told that their are more than announce-position-limit callers waiting.
582 * Two new queue log events have been added. An ADDMEMBER event will be logged
583 when a realtime queue member is added and a REMOVEMEMBER event will be logged
584 when a realtime queue member is removed. Since there is no calling channel associated
585 with these events, the string "REALTIME" is placed where the channel's unique id
590 * The 'o' option to provide an optimization has been removed and its functionality
591 has been enabled by default.
592 * When a conference is created, the UNIQUEID of the channel that caused it to be
593 created is stored. Then, every channel that joins the conference will have the
594 MEETMEUNIQUEID channel variable set with this ID. This can be used to relate
595 callers that come and go from long standing conferences.
596 * Added a new application, MeetMeChannelAdmin, which is similar to MeetMeAdmin,
597 except it does operations on a channel by name, instead of number in a conference.
598 This is a very useful feature in combination with the 'X' option to ChanSpy.
599 * Added 'C' option to Meetme which causes a caller to continue in the dialplan
601 * Added new RealTime functionality to provide support for scheduled conferencing.
602 This includes optional messages to the caller if they attempt to join before
603 the schedule start time, or to allow the caller to join the conference early.
604 Also included is optional support for limiting the number of callers per
606 * Added the S() and L() options to the MeetMe application. These are pretty
607 much identical to the S() and L() options to Dial(). They let you set
608 timeouts for the conference, as well as have warning sounds played to
609 let the caller know how much time is left, and when it is running out.
610 * Added the ability to do "meetme concise" with the "meetme" CLI command.
611 This extends the concise capabilities of this CLI command to include
612 listing all conferences, instead of an addition to the other sub commands
613 for the "meetme" command.
614 * Added the ability to specify the music on hold class used to play into the
615 conference when there is only one member and the M option is used.
616 * Added MEETME_INFO dialplan function which provides a way to query
617 various properties of a Meetme conference.
619 Other Dialplan Application Changes
620 ----------------------------------
621 * Argument support for Gosub application
622 * From the to-do lists: straighten out the app timeout args:
623 Wait() app now really does 0.3 seconds- was truncating arg to an int.
624 WaitExten() same as Wait().
625 Congestion() - Now takes floating pt. argument.
626 Busy() - now takes floating pt. argument.
627 Read() - timeout now can be floating pt.
628 WaitForRing() now takes floating pt timeout arg.
629 SpeechBackground() -- clarified in the docstrings that the timeout is an integer seconds.
630 * Added 's' option to Page application.
631 * Added 'E' and 'V' commands to ExternalIVR.
632 * Added 'o' and 'X' options to Chanspy.
633 * Added a new dialplan application, Bridge, which allows you to bridge the
634 calling channel to any other active channel on the system.
635 * Added the ability to specify a music on hold class to play instead of ringing
636 for the SLATrunk application.
637 * The Read application no longer exits the dialplan on error. Instead, it sets
638 READSTATUS to ERROR, which you can catch and handle separately.
639 * Added 'm' option to Directory, which lists out names, 8 at a time, instead
640 of asking for verification of each name, one at a time.
641 * Privacy() no longer uses privacy.conf, as all options are specifyable as
642 direct options to the app.
643 * AMD() has a new "maximum word length" option. "show application AMD" from the CLI
645 * GotoIfTime() now may branch based on a "false" condition, like other Goto-related applications
646 * The ChannelRedirect application no longer exits the dialplan if the given channel
647 does not exist. It will now set the CHANNELREDIRECT_STATUS variable to SUCCESS upon success
648 or NOCHANNEL if the given channel was not found.
649 * The silencethreshold setting that was previously configurable in multiple
650 applications is now settable globally via dsp.conf.
651 * Added ability to communicate over a TCP socket instead of forking a child process for the
652 ExternalIVR application.
654 Music On Hold Changes
655 ---------------------
656 * A new option, "digit", has been added for music on hold classes in
657 musiconhold.conf. If this is set for a music on hold class, a caller
658 listening to music on hold can press this digit to switch to listening
659 to this music on hold class.
660 * Support for realtime music on hold has been added.
661 * In conjunction with the realtime music on hold, a general section has
662 been added to musiconhold.conf, its sole variable is cachertclasses. If this
663 is set, then music on hold classes found in realtime will be cached in memory.
667 * AEL upgraded to use the Gosub with Arguments instead
668 of Macro application, to hopefully reduce the problems
669 seen with the artificially low stack ceiling that
670 Macro bumps into. Macros can only call other Macros
671 to a depth of 7. Tests run using gosub, show depths
672 limited only by virtual memory. A small test demonstrated
673 recursive call depths of 100,000 without problems.
674 -- in addition to this, all apps that allowed a macro
675 to be called, as in Dial, queues, etc, are now allowing
676 a gosub call in similar fashion.
677 * AEL now generates LOCAL(argname) declarations when it
678 Set()'s the each arg name to the value of ${ARG1}, ${ARG2),
679 etc. That makes the arguments local in scope. The user
680 can define their own local variables in macros, now,
681 by saying "local myvar=someval;" or using Set() in this
682 fashion: Set(LOCAL(myvar)=someval); ("local" is now
684 * utils/conf2ael introduced. Will convert an extensions.conf
685 file into extensions.ael. Very crude and unfinished, but
686 will be improved as time goes by. Should be useful for a
687 first pass at conversion.
688 * aelparse will now read extensions.conf to see if a referenced
689 macro or context is there before issueing a warning.
690 * AEL parser sets a local channel variable ~~EXTEN~~, to
691 preserve the value of ${EXTEN} thru switch statements.
692 * New operator in $[...] expressions: the ~~ operator serves
693 as a concatenation operator. AT THE MOMENT, it is really only
694 necessary and useful in AEL, especially in if() expressions.
695 Operation: ${a} ~~ ${b| with force both a and b to strings, strip
696 any enclosing double-quotes, and evaluate to the value of a
697 concatenated with the value of b. For example if a is set to
698 "xyz" and b has the value "abc", then ${a} ~~ ${b| would
702 Call Features (res_features) Changes
703 ------------------------------------
704 * Added the parkedcalltransfers option to features.conf
705 * The built-in method for doing attended transfers has been updated to
706 include some new options that allow you to have the transferee sent
707 back to the person that did the transfer if the transfer is not successful.
708 See the options "atxferdropcall", "atxferloopdelay", and "atxfercallbackretries"
709 in features.conf.sample.
710 * Added support for configuring named groups of custom call features in
711 features.conf. This means that features can be written a single time, and
712 then mapped into groups of features for different key mappings or easier
714 * Updated the ParkedCall application to allow you to not specify a parking
715 extension. If you don't specify a parking space to pick up, it will grab
716 the first one available.
717 * Added cli command 'features reload' to reload call features from features.conf
718 * Moved into core asterisk binary.
720 Language Support Changes
721 ------------------------
722 * Brazilian Portuguese (pt-BR) in VM, and say.c was added
723 * Added support for the Hungarian language for saying numbers, dates, and times.
727 * Added SPEECH commands for speech recognition. A complete listing can be found
729 * If app_stack is loaded, GOSUB is a native AGI command that may be used to
730 invoke subroutines in the dialplan. Note that calling EXEC with Gosub
731 does not behave as expected; the native command needs to be used, instead.
735 * Added rotatestrategy option to logger.conf, along with two new options:
736 "timestamp" which will use the time to name the logger files instead of
737 sequence number; and "rotate", which rotates the names of the logfiles,
738 similar to the way syslog rotates files.
739 * Added exec_after_rotate option to logger.conf, which allows a system
740 command to be run after rotation. This is primarily useful with
741 rotatestrategry=rotate, to allow a limit on the number of logfiles kept
742 and to ensure that the oldest log file gets deleted.
743 * Added realtime support for the queue log
747 * The cdr_manager module has a [mappings] feature, like cdr_custom,
748 to add fields to the manager event from the CDR variables.
749 * Added cdr_adaptive_odbc, a new module that adapts to the structure of your
750 backend database CDR table. Specifically, additional, non-standard
751 columns are supported, merely by setting the corresponding CDR variable in
752 your dialplan. In addition, you may alias any column to another name (for
753 example, if you want the 'src' CDR variable to be column 'ANI' in the DB,
754 simply "alias src => ANI" in the configuration file). Records may be
755 posted to more than one backend, simply by specifying multiple categories
756 in the configuration file. And finally, you may filter which CDRs get
757 posted to each backend, by specifying a filter (which the record must
758 match) for the particular category. Filters are additive (meaning all
759 rules must match to post that CDR).
760 * The Postgres CDR module now supports some features of the cdr_adaptive_odbc
761 module. Specifically, you may add additional columns into the table and
762 they will be set, if you set the corresponding CDR variable name. Also,
763 if you omit columns in your database table, they will be silently skipped
764 (but a record will still be inserted, based on what columns remain). Note
765 that the other two features from cdr_adaptive_odbc (alias and filter) are
766 not currently supported.
767 * The ResetCDR application now has an 'e' option that re-enables a CDR if it
768 has been disabled using the NoCDR application.
770 Miscellaneous New Modules
771 -------------------------
772 * Added a new CDR module, cdr_sqlite3_custom.
773 * Added a new realtime configuration module, res_config_sqlite
774 * Added a new codec translation module, codec_resample, which re-samples
775 signed linear audio between 8 kHz and 16 kHz to help support wideband
777 * Added a new module, res_phoneprov, which allows auto-provisioning of phones
778 based on configuration templates that use Asterisk dialplan function and
779 variable substitution. It should be possible to create phone profiles and
780 templates that work for the majority of phones provisioned over http. It
781 is currently only intended to provision a single user account per phone.
782 An example profile and set of templates for Polycom phones is provided.
783 NOTE: Polycom firmware is not included, but should be placed in
784 AST_DATA_DIR/phoneprov/configs to match up with the included templates.
785 * Added a new module, app_jack, which provides interfaces to JACK, the Jack
786 Audio Connection Kit (http://www.jackaudio.org/). Two interfaces are
787 provided; there is a JACK() application, and a JACK_HOOK() function. Both
788 interfaces create an input and output JACK port. The application makes
789 these ports the endpoint of the call. The audio coming from the channel
790 goes out the output port and whatever comes back in on the input port is
791 what gets sent to the channel. The JACK_HOOK() function turns on a JACK
792 audiohook on the channel. This lets you run the audio coming from a
793 channel through JACK, and whatever comes back in is what gets forwarded
794 on as the channel's audio. This is very useful for building custom
795 vocoders or doing recording or analysis of the channel's audio in another
797 * Added a new module, res_config_curl, which permits using a HTTP POST url
798 to retrieve, create, update, and delete realtime information from a remote
799 web server. Note that this module requires func_curl.so to be loaded for
800 backend functionality.
801 * Added a new module, res_config_ldap, which permits the use of an LDAP
802 server for realtime data access.
803 * Added support for writing and running your dialplan in lua using the pbx_lua
804 module. See configs/extensions.lua.sample for examples of how to do this.
808 * res_jabber: autoprune has been disabled by default, to avoid misconfiguration
809 that would end up being interpreted as a bug once Asterisk started removing
810 the contacts from a user list.
811 * Ability to use libcap to set high ToS bits when non-root
812 on Linux. If configure is unable to find libcap then you
813 can use --with-cap to specify the path.
814 * Added maxfiles option to options section of asterisk.conf which allows you to specify
815 what Asterisk should set as the maximum number of open files when it loads.
816 * Added the jittertargetextra configuration option.
817 * Added support for setting the CoS for VLAN traffic (802.1p). See the sample
818 configuration files for the IP channel drivers. The new option is "cos".
819 This information is also documented in doc/qos.tex, or the IP Quality of Service
820 section of asterisk.pdf.
821 * When originating a call using AMI or pbx_spool that fails the reason for failure
822 will now be available in the failed extension using the REASON dialplan variable.
823 * Added support for reading the TOUCH_MONITOR_PREFIX channel variable.
824 It allows you to configure a prefix for auto-monitor recordings.
825 * A new extension pattern matching algorithm, based on a trie, is introduced
826 here, that could noticeably speed up mid-sized to large dialplans.
827 It is NOT used by default, as duplicating the behaviour of the old pattern
828 matcher is still under development. A config file option, in extensions.conf,
829 in the [general] section, called "extenpatternmatchingnew", is by default
830 set to false; setting that to true will force the use of the new algorithm.
831 Also, the cli commands "dialplan set extenpatternmatchingnew true/false" can
832 be used to switch the algorithms at run time.
833 * A new option when starting a remote asterisk (rasterisk, asterisk -r) for
834 specifying which socket to use to connect to the running Asterisk daemon
836 * Performance enhancements to the sched facility, which is used in
837 the channel drivers, etc. Added hashtabs and doubly-linked lists
838 to speed up deletion; start at the beginning or end of list to
840 * Added Doubly-linked lists after the fashion of linkedlists.h. They are in
841 dlinkedlists.h. Doubly-linked lists feature fast deletion times.
842 Added regression tests to the tests/ dir, also.
843 * Added a refcount trace feature to astobj2 for those trying to balance
844 object creation, deletion; work, play; space and time. See the
845 notes in astobj2.h. Also, see utils/refcounter as well, as a
846 quick way to find unbalanced refcounts in what could be a sea
847 of objects that were balanced.
848 * Added logging to 'make update' command. See update.log
849 * Added strictrtp option to rtp.conf. If enabled this will drop RTP packets that
850 do not come from the remote party.
851 * Added the 'n' option to the SpeechBackground application to tell it to not
852 answer the channel if it has not already been answered.
853 * Added a compiler flag, CHANNEL_TRACE, which permits channel tracing to be
854 turned on, via the CHANNEL(trace) dialplan function. Could be useful for
856 * iLBC source code no longer included (see UPGRADE.txt for details)
857 * If compiled with DETECT_DEADLOCKS enabled and if you have glibc, then if
858 deadlock is detected, a backtrace of the stack which led to the lock calls
859 will be output to the CLI.
860 * If compiled with DEBUG_THREADS enabled and if you have glibc, then issuing
861 the "core show locks" CLI command will give lock information output as well
862 as a backtrace of the stack which led to the lock calls.
863 * users.conf now sports an optional alternateexts property, which permits
864 allocation of additional extensions which will reach the specified user.
865 * A new option for the configure script, --enable-internal-poll, has been added
866 for use with systems which may have a buggy implementation of the poll system
867 call. If you notice odd behavior such as the CLI being unresponsive on remote
868 consoles, you may want to try using this option. This option is enabled by default
869 on Darwin systems since it is known that the Darwin poll() implementation has
projects / asterisk/asterisk.git / blob
