3 === Information for upgrading between Asterisk versions
5 === These files document all the changes that MUST be taken
6 === into account when upgrading between the Asterisk
7 === versions listed below. These changes may require that
8 === you modify your configuration files, dialplan or (in
9 === some cases) source code if you have your own Asterisk
10 === modules or patches. These files also includes advance
11 === notice of any functionality that has been marked as
12 === 'deprecated' and may be removed in a future release,
13 === along with the suggested replacement functionality.

19 ===========================================================
23 * Asterisk now requires libpri 1.4.11+ for PRI support.
25 * A couple of CLI commands in res_ais were changed back to their original form:
26 "ais show clm members" --> "ais clm show members"
27 "ais show evt event channels" --> "ais evt show event channels"
29 * The default value for 'autofill' and 'shared_lastcall' in queues.conf has
30 been changed to 'yes'.
32 * The default value for the alwaysauthreject option in sip.conf has been changed
35 * The behavior of the 'parkedcallstimeout' has changed slightly. The formulation
36 of the extension name that a timed out parked call is delivered to when this
37 option is set to 'no' was modified such that instead of converting '/' to '0',
38 the '/' is converted to an underscore '_'. See the updated documentation in
39 features.conf.sample for more information on the behavior of the
40 'parkedcallstimeout' option.
42 * Asterisk-addons no longer exists as an independent package. Those modules
43 now live in the addons directory of the main Asterisk source tree. They
44 are not enabled by default. For more information about why modules live in
45 addons, see README-addons.txt.
47 * The rarely used 'event_log' and LOG_EVENT channel have been removed; the few
48 users of this channel in the tree have been converted to LOG_NOTICE or removed
49 (in cases where the same message was already generated to another channel).
51 * The usage of RTP inside of Asterisk has now become modularized. This means
52 the Asterisk RTP stack now exists as a loadable module, res_rtp_asterisk.
53 If you are not using autoload=yes in modules.conf you will need to ensure
54 it is set to load. If not, then any module which uses RTP (such as chan_sip)
55 will not be able to send or receive calls.
57 * The app_dahdiscan.c file has been removed, but the dialplan app DAHDIScan still
58 remains. It now exists within app_chanspy.c and retains the exact same
59 functionality as before.
61 * The default behavior for Set, AGI, and pbx_realtime has been changed to implement
62 1.6 behavior by default, if there is no [compat] section in asterisk.conf. In
63 prior versions, the behavior defaulted to 1.4 behavior, to assist in upgrades.
64 Specifically, that means that pbx_realtime and res_agi expect you to use commas
65 to separate arguments in applications, and Set only takes a single pair of
66 a variable name/value. The old 1.4 behavior may still be obtained by setting
67 app_set, pbx_realtime, and res_agi each to 1.4 in the [compat] section of
70 * The PRI channels in chan_dahdi can no longer change the channel name if a
71 different B channel is selected during call negotiation. To prevent using
72 the channel name to infer what B channel a call is using and to avoid name
73 collisions, the channel name format is changed.
74 The new channel naming for PRI channels is:
75 DAHDI/i<span>/<number>[:<subaddress>]-<sequence-number>
77 * Added CHANNEL(dahdi_span), CHANNEL(dahdi_channel), and CHANNEL(dahdi_type)
78 so the dialplan can determine the B channel currently in use by the channel.
79 Use CHANNEL(no_media_path) to determine if the channel even has a B channel.
81 * Added AMI event DAHDIChannel to associate a DAHDI channel with an Asterisk
82 channel so AMI applications can passively determine the B channel currently
83 in use. Calls with "no-media" as the DAHDIChannel do not have an associated
84 B channel. No-media calls are either on hold or call-waiting.
86 * The ChanIsAvail application has been changed so the AVAILSTATUS variable
87 no longer contains both the device state and cause code. The cause code
88 is now available in the AVAILCAUSECODE variable. If existing dialplan logic
89 is written to expect AVAILSTATUS to contain the cause code it needs to be
90 changed to use AVAILCAUSECODE.
92 * ExternalIVR will now send Z events for invalid or missing files, T events
93 now include the interrupted file and bugs in argument parsing have been
94 fixed so there may be arguments specified in incorrect ways that were
95 working that will no longer work.
96 Please see doc/externalivr.txt for details.
98 * OSP lookup application changes following variable names:
99 OSPPEERIP to OSPINPEERIP
100 OSPTECH to OSPOUTTECH
101 OSPDEST to OSPDESTINATION
102 OSPCALLING to OSPOUTCALLING
103 OSPCALLED to OSPOUTCALLED
104 OSPRESULTS to OSPDESTREMAILS
106 * The Manager event 'iax2 show peers' output has been updated. It now has a
107 similar output of 'sip show peers'.
109 * VoiceMailMain and VMAuthenticate, if a '*' is entered in the first position
110 of a Mailbox or Password, will, if it exists, jump to the 'a' extension in
111 the current dialplan context.
113 * The CALLERPRES() dialplan function is deprecated in favor of
114 CALLERID(num-pres) and CALLERID(name-pres).
116 * Environment variables that start with "AST_" are reserved to the system and
117 may no longer be set from the dialplan.
119 * When a call is redirected inside of a Dial, the app and appdata fields of the
120 CDR will now be set to "AppDial" and "(Outgoing Line)" instead of being blank.
122 * The CDR handling of billsec and duration field has changed. If your table
123 definition specifies those fields as float,double or similar they will now
124 be logged with microsecond accuracy instead of a whole integer.
126 * chan_sip will no longer set up a local call forward when receiving a
127 482 Loop Detected response. The dialplan will just continue from where it
130 * The 'stunaddr' option has been removed from chan_sip. This feature did not
131 behave as expected, had no correct use case, and was not RFC compliant. The
132 removal of this feature will hopefully be followed by a correct RFC compliant
133 STUN implementation in chan_sip in the future.
135 * The default value for the pedantic option in sip.conf has been changed
138 * The ConnectedLineNum and ConnectedLineName headers were added to many AMI
139 events/responses if the CallerIDNum/CallerIDName headers were also present.
140 The addition of connected line support changes the behavior of the channel
141 caller ID somewhat. The channel caller ID value no longer time shares with
142 the connected line ID on outgoing call legs. The timing of some AMI
143 events/responses output the connected line ID as caller ID. These party ID's
146 * The Dial application d and H options do not automatically answer the call
147 anymore. It broke DTMF attended transfers. Since many SIP and ISDN phones
148 cannot send DTMF before a call is connected, you need to answer the call
149 leg to those phones before using Dial with these options for them to have
150 any effect before the dialed party answers.
152 * The outgoing directory (where .call files are read) now uses inotify to
153 detect file changes instead of polling the directory on a regular basis.
154 If your outgoing folder is on a NFS mount or another network file system,
155 changes to the files will not be detected. You can revert to polling the
156 directory by specifying --without-inotify to configure before compiling.
160 * SIP no longer sends the 183 progress message for early media by
161 default. Applications requiring early media should use the
162 progress() dialplan app to generate the progress message.
164 * The firmware for the IAXy has been removed from Asterisk. It can be
165 downloaded from http://downloads.digium.com/pub/iaxy/. To have Asterisk
166 install the firmware into its proper location, place the firmware in the
167 contrib/firmware/iax/ directory in the Asterisk source tree before running
170 * T.38 FAX error correction mode can no longer be configured in udptl.conf;
171 instead, it is configured on a per-peer (or global) basis in sip.conf, with
172 the same default as was present in udptl.conf.sample.
174 * T.38 FAX maximum datagram size can no longer be configured in updtl.conf;
175 instead, it is either supplied by the application servicing the T.38 channel
176 (for a FAX send or receive) or calculated from the bridged endpoint's
177 maximum datagram size (for a T.38 FAX passthrough call). In addition, sip.conf
178 allows for overriding the value supplied by a remote endpoint, which is useful
179 when T.38 connections are made to gateways that supply incorrectly-calculated
180 maximum datagram sizes.
182 * There have been some changes to the IAX2 protocol to address the security
183 concerns documented in the security advisory AST-2009-006. Please see the
184 IAX2 security document, doc/IAX2-security.pdf, for information regarding
185 backwards compatibility with versions of Asterisk that do not contain these
188 * The 'canreinvite' option support by the SIP, MGCP and Skinny channel drivers
189 has been renamed to 'directmedia', to better reflect what it actually does.
190 In the case of SIP, there are still re-INVITEs issued for T.38 negotiation,
191 starting and stopping music-on-hold, and other reasons, and the 'canreinvite'
192 option never had any effect on these cases, it only affected the re-INVITEs
193 used for direct media path setup. For MGCP and Skinny, the option was poorly
194 named because those protocols don't even use INVITE messages at all. For
195 backwards compatibility, the old option is still supported in both normal
196 and Realtime configuration files, but all of the sample configuration files,
197 Realtime/LDAP schemas, and other documentation refer to it using the new name.
199 * The default console now will use colors according to the default background
200 color, instead of forcing the background color to black. If you are using a
201 light colored background for your console, you may wish to use the option
202 flag '-W' to present better color choices for the various messages. However,
203 if you'd prefer the old method of forcing colors to white text on a black
204 background, the compatibility option -B is provided for this purpose.
206 * SendImage() no longer hangs up the channel on transmission error or on
207 any other error; in those cases, a FAILURE status is stored in
208 SENDIMAGESTATUS and dialplan execution continues. The possible
209 return values stored in SENDIMAGESTATUS are: SUCCESS, FAILURE, and
210 UNSUPPORTED. ('OK' has been replaced with 'SUCCESS', and 'NOSUPPORT'
211 has been replaced with 'UNSUPPORTED'). This change makes the
212 SendImage application more consistent with other applications.
214 * skinny.conf now has separate sections for lines and devices.
215 Please have a look at configs/skinny.conf.sample and update
218 * Queue names previously were treated in a case-sensitive manner,
219 meaning that queues with names like "sales" and "sALeS" would be
220 seen as unique queues. The parsing logic has changed to use
221 case-insensitive comparisons now when originally hashing based on
222 queue names, meaning that now the two queues mentioned as examples
223 earlier will be seen as having the same name.
225 * The SPRINTF() dialplan function has been moved into its own module,
226 func_sprintf, and is no longer included in func_strings. If you use this
227 function and do not use 'autoload=yes' in modules.conf, you will need
228 to explicitly load func_sprintf for it to be available.
230 * The res_indications module has been removed. Its functionality was important
231 enough that most of it has been moved into the Asterisk core.
232 Two applications previously provided by res_indications, PlayTones and
233 StopPlayTones, have been moved into a new module, app_playtones.
235 * Support for Taiwanese was incorrectly supported with the "tw" language code.
236 In reality, the "tw" language code is reserved for the Twi language, native
237 to Ghana. If you were previously using the "tw" language code, you should
238 switch to using either "zh" (for Mandarin Chinese) or "zh_TW" for Taiwan
239 specific localizations. Additionally, "mx" should be changed to "es_MX",
240 Georgian was incorrectly specified as "ge" but should be "ka", and Czech is
243 * DAHDISendCallreroutingFacility() parameters are now comma-separated,
244 instead of the old pipe.
246 * res_jabber: autoprune has been disabled by default, to avoid misconfiguration
247 that would end up being interpreted as a bug once Asterisk started removing
248 the contacts from a user list.
250 * The cdr.conf file must exist and be configured correctly in order for CDR
251 records to be written.
253 From 1.6.0.1 to 1.6.1:
255 * The ast_agi_register_multiple() and ast_agi_unregister_multiple()
256 API calls were added in 1.6.0, so that modules that provide multiple
257 AGI commands could register/unregister them all with a single
258 step. However, these API calls were not implemented properly, and did
259 not allow the caller to know whether registration or unregistration
260 succeeded or failed. They have been redefined to now return success
261 or failure, but this means any code using these functions will need
262 be recompiled after upgrading to a version of Asterisk containing
263 these changes. In addition, the source code using these functions
264 should be reviewed to ensure it can properly react to failure
265 of registration or unregistration of its API commands.
267 * The ast_agi_fdprintf() API call has been renamed to ast_agi_send()
268 to better match what it really does, and the argument order has been
269 changed to be consistent with other API calls that perform similar
272 From 1.6.0.x to 1.6.1:
274 * In previous versions of Asterisk, due to the way objects were arranged in
275 memory by chan_sip, the order of entries in sip.conf could be adjusted to
276 control the behavior of matching against peers and users. The way objects
277 are managed has been significantly changed for reasons involving performance
278 and stability. A side effect of these changes is that the order of entries
279 in sip.conf can no longer be relied upon to control behavior.
281 * The following core commands dealing with dialplan have been deprecated: 'core
282 show globals', 'core set global' and 'core set chanvar'. Use the equivalent
283 'dialplan show globals', 'dialplan set global' and 'dialplan set chanvar'
286 * In the dialplan expression parser, the logical value of spaces
287 immediately preceding a standalone 0 previously evaluated to
288 true. It now evaluates to false. This has confused a good many
289 people in the past (typically because they failed to realize the
290 space had any significance). Since this violates the Principle of
291 Least Surprise, it has been changed.
293 * While app_directory has always relied on having a voicemail.conf or users.conf file
294 correctly set up, it now is dependent on app_voicemail being compiled as well.
296 * SIP: All of the functionality in SIPCHANINFO() has been implemented in CHANNEL(),
297 and you should start using that function instead for retrieving information about
298 the channel in a technology-agnostic way.
300 * If you have any third party modules which use a config file variable whose
301 name ends in a '+', please note that the append capability added to this
302 version may now conflict with that variable naming scheme. An easy
303 workaround is to ensure that a space occurs between the '+' and the '=',
304 to differentiate your variable from the append operator. This potential
305 conflict is unlikely, but is documented here to be thorough.
307 * The "Join" event from app_queue now uses the CallerIDNum header instead of
308 the CallerID header to indicate the CallerID number.
310 * If you use ODBC storage for voicemail, there is a new field called "flag"
311 which should be a char(8) or larger. This field specifies whether or not a
312 message has been designated to be "Urgent", "PRIORITY", or not.
