8 =========================================================
12 * Macros are now implemented underneath with the Gosub() application.
13 Heaven Help You if you wrote code depending on any aspect of this!
14 Previous to 1.6, macros were implemented with the Macro() app, which
15 provided a nice feature of auto-returning. The compiler will do its
16 best to insert a Return() app call at the end of your macro if you did
17 not include it, but really, you should make sure that all execution
18 paths within your macros end in "return;".
20 * The conf2ael program is 'introduced' in this release; it is in a rather
21 crude state, but deemed useful for making a first pass at converting
22 extensions.conf code into AEL. More intelligence will come with time.
26 * The 'languageprefix' option in asterisk.conf is now deprecated, and
27 the default sound file layout for non-English sounds is the 'new
28 style' layout introduced in Asterisk 1.4 (and used by the automatic
29 sound file installer in the Makefile).
31 * The ast_expr2 stuff has been modified to handle floating-point numbers.
32 Numbers of the format D.D are now acceptable input for the expr parser,
33 Where D is a string of base-10 digits. All math is now done in "long double",
34 if it is available on your compiler/architecture. This was half-way between
35 a bug-fix (because the MATH func returns fp by default), and an enhancement.
36 Also, for those counting on, or needing, integer operations, a series of
37 'functions' were also added to the expr language, to allow several styles
38 of rounding/truncation, along with a set of common floating point operations,
39 like sin, cos, tan, log, pow, etc. The ability to call external functions
40 like CDR(), etc. was also added, without having to use the ${...} notation.
42 * The delimiter passed to applications has been changed to the comma (','), as
43 that is what people are used to using within extensions.conf. If you are
44 using realtime extensions, you will need to translate your existing dialplan
45 to use this separator. To use a literal comma, you need merely to escape it
46 with a backslash ('\'). Another possible side effect is that you may need to
47 remove the obscene level of backslashing that was necessary for the dialplan
48 to work correctly in 1.4 and previous versions. This should make writing
49 dialplans less painful in the future, albeit with the pain of a one-time
50 conversion. If you would like to avoid this conversion immediately, set
51 pbx_realtime=1.4 in the [compat] section of asterisk.conf. After
52 transitioning, set pbx_realtime=1.6 in the same section.
54 * For the same purpose as above, you may set res_agi=1.4 in the [compat]
55 section of asterisk.conf to continue to use the '|' delimiter in the EXEC
56 arguments of AGI applications. After converting to use the ',' delimiter,
57 change this option to res_agi=1.6.
59 * The logger.conf option 'rotatetimestamp' has been deprecated in favor of
60 'rotatestrategy'. This new option supports a 'rotate' strategy that more
61 closely mimics the system logger in terms of file rotation.
63 * The concise versions of various CLI commands are now deprecated. We recommend
64 using the manager interface (AMI) for application integration with Asterisk.
66 * The following core commands dealing with dialplan has been deprecated: 'core
67 show globals', 'core set global' and 'core set chanvar'. Use the equivalent
68 'dialplan show globals', 'dialplan set global' and 'dialplan set chanvar'
71 * The silencethreshold used for various applications is now settable via a
72 centralized config option in dsp.conf.
74 * The logical value of spaces immediately preceding a standalone 0 previously
75 evaluated to true. It now evaluates to false. This has confused a good
76 many people in the past (typically because they failed to realize the space
77 had any significance). Since this violates the Principle of Least Surprise,
82 * The voicemail configuration values 'maxmessage' and 'minmessage' have
83 been changed to 'maxsecs' and 'minsecs' to clarify their purpose and
84 to make them more distinguishable from 'maxmsgs', which sets folder
85 size. The old variables will continue to work in this version, albeit
86 with a deprecation warning.
88 * If you use any interface for modifying voicemail aside from the built in
89 dialplan applications, then the option "pollmailboxes" *must* be set in
90 voicemail.conf for message waiting indication (MWI) to work properly. This
91 is because Voicemail notification is now event based instead of polling
92 based. The channel drivers are no longer responsible for constantly manually
93 checking mailboxes for changes so that they can send MWI information to users.
94 Examples of situations that would require this option are web interfaces to
95 voicemail or an email client in the case of using IMAP storage.
97 * The externnotify script should accept an additional (last) parameter
98 containing the number of urgent messages in the INBOX.
102 * SendImage() no longer hangs up the channel on transmission error or on
103 another type of error; in those cases, a FAILURE status is stored in
104 SENDIMAGESTATUS and dialplan execution continues. The possible return values
105 stored in SENDIMAGESTATUS are: SUCCESS, FAILURE, and UNSUPPORTED. ('OK' has
106 been replaced with 'SUCCESS', and 'NOSUPPORT' has been replaced with
107 'UNSUPPORTED'). This change makes the SendImage application more consistent
108 with other applications.
110 * ChanIsAvail() now has a 't' option, which allows the specified device
111 to be queried for state without consulting the channel drivers. This
112 performs mostly a 'ChanExists' sort of function.
114 * ChannelRedirect() will not terminate the channel that fails to do a
115 channelredirect as it has done previously. Instead CHANNELREDIRECT_STATUS
116 will reflect if the attempt was successful of not.
118 * SetCallerPres() has been replaced with the CALLERPRES() dialplan function
119 and is now deprecated.
121 * DISA()'s fifth argument is now an options argument. If you have previously
122 used 'NOANSWER' in this argument, you'll need to convert that to the new
125 * Macro() is now deprecated. If you need subroutines, you should use the
126 Gosub()/Return() applications. To replace MacroExclusive(), we have
127 introduced dialplan functions LOCK(), TRYLOCK(), and UNLOCK(). You may use
128 these functions in any location where you desire to ensure that only one
129 channel is executing that path at any one time. The Macro() applications
130 are deprecated for performance reasons. However, since Macro() has been
131 around for a long time and so many dialplans depend heavily on it, for the
132 sake of backwards compatibility it will not be removed . It is also worth
133 noting that using both Macro() and GoSub() at the same time is _heavily_
136 * Read() now sets a READSTATUS variable on exit. It does NOT automatically
137 return -1 (and hangup) anymore on error. If you want to hangup on error,
138 you need to do so explicitly in your dialplan.
140 * Privacy() no longer uses privacy.conf, so any options must be specified
141 directly in the application arguments.
143 * MusicOnHold application now has duration parameter which allows specifying
146 * WaitMusicOnHold application is now deprecated in favor of extended MusicOnHold.
148 * SetMusicOnHold is now deprecated. You should use Set(CHANNEL(musicclass)=...)
151 * While app_directory has always relied on having a voicemail.conf or users.conf file
152 correctly set up, it now is dependent on app_voicemail being compiled as well.
154 * The arguments in ExecIf changed a bit, to be more like other applications.
155 The syntax is now ExecIf(<cond>?appiftrue(args):appiffalse(args)).
157 * The behavior of the Set application now depends upon a compatibility option,
158 set in asterisk.conf. To use the old 1.4 behavior, which allowed Set to take
159 multiple key/value pairs, set app_set=1.4 in [compat] in asterisk.conf. To
160 use the new behavior, which permits variables to be set with embedded commas,
161 set app_set=1.6 in [compat] in asterisk.conf. Note that you can have both
162 behaviors at the same time, if you switch to using MSet if you want the old
167 * QUEUE_MEMBER_COUNT() has been deprecated in favor of the QUEUE_MEMBER() function. For
168 more information, issue a "show function QUEUE_MEMBER" from the CLI.
172 * The cdr_sqlite module has been marked as deprecated in favor of
173 cdr_sqlite3_custom. It will potentially be removed from the tree
174 after Asterisk 1.6 is released.
176 * The cdr_odbc module now uses res_odbc to manage its connections. The
177 username and password parameters in cdr_odbc.conf, therefore, are no
178 longer used. The dsn parameter now points to an entry in res_odbc.conf.
180 * The uniqueid field in the core Asterisk structure has been changed from a
181 maximum 31 character field to a 149 character field, to account for all
182 possible values the systemname prefix could be. In the past, if the
183 systemname was too long, the uniqueid would have been truncated.
185 * The cdr_tds module now supports all versions of FreeTDS that contain
186 the db-lib frontend. It will also now log the userfield variable if
187 the target database table contains a column for it.
191 * format_wav: The GAIN preprocessor definition and source code that used it
192 is removed. This change was made in response to user complaints of
193 choppiness or the clipping of loud signal peaks. To increase the volume
194 of voicemail messages, use the 'volgain' option in voicemail.conf
198 * SIP: a small upgrade to support the "Record" button on the SNOM360,
199 which sends a sip INFO message with a "Record: on" or "Record: off"
200 header. If Asterisk is set up (via features.conf) to accept "One Touch Monitor"
201 requests (by default, via '*1'), then the user-configured dialpad sequence
202 is generated, and recording can be started and stopped via this button. The
203 file names and formats are all controlled via the normal mechanisms. If the
204 user has not configured the automon feature, the normal "415 Unsupported media type"
205 is returned, and nothing is done.
207 * SIP: The "call-limit" option is marked as deprecated. It still works in this version of
208 Asterisk, but will be removed in the following version. Please use the groupcount functions
209 in the dialplan to enforce call limits. The "limitonpeer" configuration option is
210 now renamed to "counteronpeer".
212 * SIP: The "username" option is now renamed to "defaultuser" to match "defaultip".
213 These are used only before registration to call a peer with the uri
214 sip:defaultuser@defaultip
215 The "username" setting still work, but is deprecated and will not work in
216 the next version of Asterisk.
218 * SIP: All of the functionality in SIPCHANINFO() has been implemented in CHANNEL(),
219 and you should start using that function instead for retrieving information about
220 the channel in a technology-agnostic way.
222 * chan_local.c: the comma delimiter inside the channel name has been changed to a
223 semicolon, in order to make the Local channel driver compatible with the comma
224 delimiter change in applications.
226 * H323: The "tos" setting has changed name to "tos_audio" and "cos" to "cos_audio"
227 to be compatible with settings in sip.conf. The "tos" and "cos" configuration
228 is deprecated and will stop working in the next release of Asterisk.
230 * Console: A new console channel driver, chan_console, has been added to Asterisk.
231 This new module can not be loaded at the same time as chan_alsa or chan_oss. The
232 default modules.conf only loads one of them (chan_oss by default). So, unless you
233 have modified your modules.conf to not use the autoload option, then you will need
234 to modify modules.conf to add another "noload" line to ensure that only one of
235 these three modules gets loaded.
237 * DAHDI: The chan_zap module that supported PSTN interfaces using
238 Zaptel has been renamed to chan_dahdi, and only supports the DAHDI
239 telephony driver package for PSTN interfaces. See the
240 Zaptel-to-DAHDI.txt file for more details on this transition.
242 * DAHDI: The "msdstrip" option has been deprecated, as it provides no value over
243 the method of stripping digits in the dialplan using variable substring syntax.
247 * pbx_dundi.c: tos parameter changed to use new values. Old values like lowdelay,
248 lowcost and other is not acceptable now. Look into qos.tex for description of
251 * queues.conf: the queue-lessthan sound file option is no longer available, and the
252 queue-round-seconds option no longer takes '1' as a valid parameter.
254 * If you have any third party modules which use a config file variable whose
255 name ends in a '+', please note that the append capability added to this
256 version may now conflict with that variable naming scheme. An easy
257 workaround is to ensure that a space occurs between the '+' and the '=',
258 to differentiate your variable from the append operator. This potential
259 conflict is unlikely, but is documented here to be thorough.
263 * Manager has been upgraded to version 1.1 with a lot of changes.
264 Please check doc/manager_1_1.txt for information
266 * The IAXpeers command output has been changed to more closely resemble the
267 output of the SIPpeers command.
269 * cdr_manager now reports at the "cdr" level, not at "call" You may need to
270 change your manager.conf to add the level to existing AMI users, if they
271 want to see the CDR events generated.
273 * The Originate command now requires the Originate write permission. For
274 Originate with the Application parameter, you need the additional System
275 privilege if you want to do anything that calls out to a subshell.
279 * New queue log events ADDMEMBER and REMOVEMEMBER have been added. Also, a
280 new value has been added to the TRANSFER event that indicates the caller's
281 original position in the queue they are being transfered from.
285 * Previously, the Asterisk source code distribution included the iLBC
286 encoder/decoder source code, from Global IP Solutions
287 (http://www.gipscorp.com). This code is not licensed for
288 distribution, and thus has been removed from the Asterisk source
289 code distribution. If you wish to use codec_ilbc to support iLBC
290 channels in Asterisk, you can run the contrib/scripts/get_ilbc_source.sh
291 script to download the source and put it in the proper place in
292 the Asterisk build tree. Once that is done you can follow your normal
293 steps of building Asterisk. You will need to run 'menuselect' and enable
294 the iLBC codec in the 'Codec Translators' category.
