1 ------------------------------------------------------------------------------
2 --- Functionality changes since Asterisk 1.4-beta was branched ----------------
3 -------------------------------------------------------------------------------
5 AMI - The manager (TCP/TLS/HTTP)
6 --------------------------------
7 * Added TLS support for the manager interface and HTTP server
8 * Added the URI redirect option for the built-in HTTP server
9 * The output of CallerID in Manager events is now more consistent.
10 CallerIDNum is used for number and CallerIDName for name.
11 * enable https support for builtin web server.
12 See configs/http.conf.sample for details.
13 * Added a new action, GetConfigJSON, which can return the contents of an
14 Asterisk configuration file in JSON format. This is intended to help
15 improve the performance of AJAX applications using the manager interface
17 * SIP and IAX manager events now use "ChannelType" in all cases where we
18 indicate channel driver. Previously, we used a mixture of "Channel"
19 and "ChannelDriver" headers.
20 * Added a "Bridge" action which allows you to bridge any two channels that
21 are currently active on the system.
22 * Added a "ListAllVoicemailUsers" action that allows you to get a list of all
23 the voicemail users setup.
24 * Added 'DBDel' and 'DBDelTree' manager commands.
28 * Added the DEVICE_STATE() dialplan function which allows retrieving any device
29 state in the dialplan, as well as creating custom device states that are
30 controllable from the dialplan.
31 * Extend CALLERID() function with "pres" and "ton" parameters to
32 fetch string representation of calling number presentation indicator
33 and numeric representation of type of calling number value.
34 * MailboxExists converted to dialplan function
35 * A new option to Dial() for telling IP phones not to count the call
36 as "missed" when dial times out and cancels.
37 * Added LOCK(), TRYLOCK(), and UNLOCK(), which provide a single level dialplan
38 mutex. No deadlocks are possible, as LOCK() only allows a single lock to be
39 held for any given channel. Also, locks are automatically freed when a
41 * Added HINT() dialplan function that allows retrieving hint information.
42 Hints are mappings between extensions and devices for the sake of
43 determining the state of an extension. This function can retrieve the list
44 of devices or the name associated with a hint.
45 * Added EXTENSION_STATE() dialplan function which allows retrieving the state
50 * New CLI command "core show settings"
51 * Added 'core show channels count' CLI command.
52 * Added the ability to set the core debug and verbose values on a per-file basis.
53 * Added 'queue pause member' and 'queue unpause member' CLI commands
57 * Improved NAT and STUN support.
58 chan_sip now can use port numbers in bindaddr, externip and externhost
59 options, as well as contact a STUN server to detect its external address
60 for the SIP socket. See sip.conf.sample, 'NAT' section.
61 * The default SIP useragent= identifier now includes the Asterisk version
62 * A new option, match_auth_username in sip.conf changes the matching of incoming requests.
63 If set, and the incoming request carries authentication info,
64 the username to match in the users list is taken from the Digest header
65 rather than from the From: field. This feature is considered experimental.
66 * The "musiconhold" and "musicclass" settings in sip.conf are now removed,
67 since they where replaced by "mohsuggest" and "mohinterpret" in version 1.4
68 * The "localmask" setting was removed in version 1.2 and the reminder about it
69 being removed is now also removed.
70 * A new option "busy-level" for setting a level of calls where asterisk reports
71 a device as busy, to separate it from call-limit
72 * A new realtime family called "sipregs" is now supported to store SIP registration
73 data. If this family is defined, "sippeers" will be used for configuration and
74 "sipregs" for registrations. If it's not defined, "sippeers" will be used for
75 registration data, as before.
76 * The SIPPEER function have new options for port address, call and pickup groups
77 * Added support for T.140 realtime text in SIP/RTP
78 * The "checkmwi" option has been removed from sip.conf, as it is no longer
79 required due to the restructuring of how MWI is handled. See the descriptions
80 in this file of the "pollmailboxes" and "pollfreq" options to voicemail.conf
82 * Added rtpdest option to CHANNEL() dialplan function.
83 * Added SIPREFERRINGCONTEXT and SIPREFERREDBYHDR variables which are set when a transfer takes place.
84 * SIP now adds a header to the CANCEL if the call was answered by another phone
85 in the same dial command, or if the new c option in dial() is used.
86 * The new default is that 100 Trying is not sent on REGISTER attempts as the RFC specifically
87 states it is not needed. For phones, however, that do require it the registertrying option
88 has been added so it can be enabled.
92 * Added the trunkmaxsize configuration option to chan_iax2.
93 * Added the srvlookup option to iax.conf
94 * Added support for OSP. The token is set and retrieved through the CHANNEL()
99 * Added skinny show device, skinny show line, and skinny show settings CLI commands.
103 * Added the ability to specify arguments to the Dial application when using
104 the DUNDi switch in the dialplan.
105 * Added the ability to set weights for responses dynamically. This can be
106 done using a global variable or a dialplan function. Using the SHELL()
107 function would allow you to have an external script set the weight for
109 * Added two new dialplan functions, DUNDIQUERY and DUNDIRESULT. These
110 functions will allow you to initiate a DUNDi query from the dialplan,
111 find out how many results there are, and access each one.
115 * Added two new dialplan functions, ENUMQUERY and ENUMRESULT. These
116 functions will allow you to initiate an ENUM lookup from the dialplan,
117 and Asterisk will cache the results. ENUMRESULT can be used to access
118 the results without doing multiple DNS queries.
122 * Added the ability to customize which sound files are used for some of the
123 prompts within the Voicemail application by changing them in voicemail.conf
124 * Added the ability for the "voicemail show users" CLI command to show users
125 configured by the dynamic realtime configuration method.
126 * MWI (Message Waiting Indication) handling has been significantly
127 restructured internally to Asterisk. It is now totally event based
128 instead of polling based. The voicemail application will notify other
129 modules that have subscribed to MWI events when something in the mailbox
131 This also means that if any other entity outside of Asterisk is changing
132 the contents of mailboxes, then the voicemail application still needs to
133 poll for changes. Examples of situations that would require this option
134 are web interfaces to voicemail or an email client in the case of using
135 IMAP storage. So, two new options have been added to voicemail.conf
136 to account for this: "pollmailboxes" and "pollfreq". See the sample
137 configuration file for details.
138 * Added "tw" language support
139 * Added support for storage of greetings using an IMAP server
140 * Added ability to customize forward, reverse, stop, and pause keys for message playback
141 * SMDI is now enabled in voicemail using the smdienable option.
142 * A "lockmode" option has been added to asterisk.conf to configure the file
143 locking method used for voicemail, and potentially other things in the
144 future. The default is the old behavior, lockfile. However, there is a
145 new method, "flock", that uses a different method for situations where the
146 lockfile will not work, such as on SMB/CIFS mounts.
150 * Added QUEUE_VARIABLES function to set queue variables added setqueuevar and
151 setqueueentryvar options for each queue, see queues.conf.sample for details.
152 * Added keepstats option to queues.conf which will keep queue
153 statistics during a reload.
154 * setinterfacevar option in queues.conf also now sets a variable
155 called MEMBERNAME which contains the member's name.
156 * Added 'Strategy' field to manager event QueueParams which represents
157 the queue strategy in use.
158 * Added option to run macro when a queue member is connected to a caller,
159 see queues.conf.sample for details.
160 * app_queue now has a 'loose' option which is almost exactly like 'strict' except it
161 does not count paused queue members as unavailable.
162 * Added min-announce-frequency option to queues.conf which allows you to control the
163 minimum amount of time between queue announcements for use when the caller's queue
164 position changes frequently.
165 * Added additional information to EXITWITHTIMEOUT and EXITWITHKEY events in the
167 * Added ability for non-realtime queues to have realtime members
171 * The 'o' option to provide an optimization has been removed and its functionality
172 has been enabled by default.
173 * When a conference is created, the UNIQUEID of the channel that caused it to be
174 created is stored. Then, every channel that joins the conference will have the
175 MEETMEUNIQUEID channel variable set with this ID. This can be used to relate
176 callers that come and go from long standing conferences.
177 * Added a new application, MeetMeChannelAdmin, which is similar to MeetMeAdmin,
178 except it does operations on a channel by name, instead of number in a conference.
179 This is a very useful feature in combination with the 'X' option to ChanSpy.
180 * Added 'C' option to Meetme which causes a caller to continue in the dialplan
183 Music On Hold Changes
184 ---------------------
185 * A new option, "digit", has been added for music on hold classes in
186 musiconhold.conf. If this is set for a music on hold class, a caller
187 listening to music on hold can press this digit to switch to listening
188 to this music on hold class.
192 * AEL upgraded to use the Gosub with Arguments instead
193 of Macro application, to hopefully reduce the problems
194 seen with the artificially low stack ceiling that
195 Macro bumps into. Macros can only call other Macros
196 to a depth of 7. Tests run using gosub, show depths
197 limited only by virtual memory. A small test demonstrated
198 recursive call depths of 100,000 without problems.
199 -- in addition to this, all apps that allowed a macro
200 to be called, as in Dial, queues, etc, are now allowing
201 a gosub call in similar fashion.
202 * AEL now generates LOCAL(argname) declarations when it
203 Set()'s the each arg name to the value of ${ARG1}, ${ARG2),
204 etc. That makes the arguments local in scope. The user
205 can define their own local variables in macros, now,
206 by saying "local myvar=someval;" or using Set() in this
207 fashion: Set(LOCAL(myvar)=someval); ("local" is now
209 * utils/conf2ael introduced. Will convert an extensions.conf
210 file into extensions.ael. Very crude and unfinished, but
211 will be improved as time goes by. Should be useful for a
212 first pass at conversion.
213 * aelparse will now read extensions.conf to see if a referenced
214 macro or context is there before issueing a warning.
216 Zaptel channel driver (chan_zap) Changes
217 ----------------------------------------
218 * SS7 support in chan_zap (via libss7 library)
219 * In India, some carriers transmit CID via dtmf. Some code has been added
220 that will handle some situations. The cidstart=polarity_IN choice has been added for
221 those carriers that transmit CID via dtmf after a polarity change.
222 * CID matching information is now shown when doing 'dialplan show'.
223 * Added zap show version CLI command to chan_zap.
224 * Added setvar support to zapata.conf channel entries.
228 * H323 remote hold notification support added (by NOTIFY message
229 and/or H.450 supplementary service)
231 Call Features (res_features) Changes
232 ------------------------------------
233 * Added the parkedcalltransfers option to features.conf
234 * The built-in method for doing attended transfers has been updated to
235 include some new options that allow you to have the transferee sent
236 back to the person that did the transfer if the transfer is not successful.
237 See the options "atxferdropcall", "atxferloopdelay", and "atxfercallbackretries"
238 in features.conf.sample.
239 * Added support for configuring named groups of custom call features in
240 features.conf. This means that features can be written a single time, and
241 then mapped into groups of features for different key mappings or easier
244 Language Support Changes
245 ------------------------
246 * Brazilian Portuguese (pt-BR) in VM, and say.c was added
247 * Added support for the Hungarian language for saying numbers, dates, and times.
251 * Added the bindaddr option to gtalk.conf.
252 * Argument support for Gosub application
253 * Ability to set process limits without restarting Asterisk
254 * Proper codec support in chan_skinny.
255 * Ability to use libcap to set high ToS bits when non-root
256 on Linux. If configure is unable to find libcap then you
257 can use --with-cap to specify the path.
258 * Added rotatetimestamp option to logger.conf which will use
259 the time to name the logger files instead of sequence number.
260 * Added Masquerade manager event for when a masquerade happens between
262 * From the to-do lists: straighten out the app timeout args:
263 Wait() app now really does 0.3 seconds- was truncating arg to an int.
264 WaitExten() same as Wait().
265 Congestion() - Now takes floating pt. argument.
266 Busy() - now takes floating pt. argument.
267 Read() - timeout now can be floating pt.
268 WaitForRing() now takes floating pt timeout arg.
269 SpeechBackground() -- clarified in the docstrings that the timeout is an integer seconds.
270 * Added maxfiles option to options section of asterisk.conf which allows you to specify
271 what Asterisk should set as the maximum number of open files when it loads.
272 * Added the jittertargetextra configuration option.
273 * Added G729 passthrough support to chan_phone for Sigma Designs boards.
274 * Added 's' option to Page application.
275 * Added 'E' and 'V' commands to ExternalIVR.
276 * Added 'o' and 'X' options to Chanspy.
277 * Added a new CDR module, cdr_sqlite3_custom.
278 * The cdr_manager module has a [mappings] feature, like cdr_custom,
279 to add fields to the manager event from the CDR variables.
280 * Added a new realtime configuration module, res_config_sqlite
281 * Added a new dialplan application, Bridge, which allows you to bridge the
282 calling channel to any other active channel on the system.
283 * Added support for setting the CoS for VLAN traffic (802.1p). See the sample
284 configuration files for the IP channel drivers. The new option is "cos".
285 This information is also documented in doc/qos.tex, or the IP Quality of Service
286 section of asterisk.pdf.
287 * The device state functionality in the Local channel driver has been updated
288 to indicate INUSE or NOT_INUSE when a Local channel is being used as opposed
289 to just UNKNOWN if the extension exists.
290 * When originating a call using AMI or pbx_spool that fails the reason for failure
291 will now be available in the failed extension using the REASON dialplan variable.
