3 === Information for upgrading from Asterisk 1.4 to 1.6
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.

18 =========================================================
22 * Macros are now implemented underneath with the Gosub() application.
23 Heaven Help You if you wrote code depending on any aspect of this!
24 Previous to 1.6, macros were implemented with the Macro() app, which
25 provided a nice feature of auto-returning. The compiler will do its
26 best to insert a Return() app call at the end of your macro if you did
27 not include it, but really, you should make sure that all execution
28 paths within your macros end in "return;".
30 * The conf2ael program is 'introduced' in this release; it is in a rather
31 crude state, but deemed useful for making a first pass at converting
32 extensions.conf code into AEL. More intelligence will come with time.
36 * The 'languageprefix' option in asterisk.conf is now deprecated, and
37 the default sound file layout for non-English sounds is the 'new
38 style' layout introduced in Asterisk 1.4 (and used by the automatic
39 sound file installer in the Makefile).
41 * The ast_expr2 stuff has been modified to handle floating-point numbers.
42 Numbers of the format D.D are now acceptable input for the expr parser,
43 Where D is a string of base-10 digits. All math is now done in "long double",
44 if it is available on your compiler/architecture. This was half-way between
45 a bug-fix (because the MATH func returns fp by default), and an enhancement.
46 Also, for those counting on, or needing, integer operations, a series of
47 'functions' were also added to the expr language, to allow several styles
48 of rounding/truncation, along with a set of common floating point operations,
49 like sin, cos, tan, log, pow, etc. The ability to call external functions
50 like CDR(), etc. was also added, without having to use the ${...} notation.
52 * The delimiter passed to applications has been changed to the comma (','), as
53 that is what people are used to using within extensions.conf. If you are
54 using realtime extensions, you will need to translate your existing dialplan
55 to use this separator. To use a literal comma, you need merely to escape it
56 with a backslash ('\'). Another possible side effect is that you may need to
57 remove the obscene level of backslashing that was necessary for the dialplan
58 to work correctly in 1.4 and previous versions. This should make writing
59 dialplans less painful in the future, albeit with the pain of a one-time
60 conversion. If you would like to avoid this conversion immediately, set
61 pbx_realtime=1.4 in the [compat] section of asterisk.conf. After
62 transitioning, set pbx_realtime=1.6 in the same section.
64 * For the same purpose as above, you may set res_agi=1.4 in the [compat]
65 section of asterisk.conf to continue to use the '|' delimiter in the EXEC
66 arguments of AGI applications. After converting to use the ',' delimiter,
67 change this option to res_agi=1.6.
69 * As a side effect of the application delimiter change, many places that used
70 to need quotes in order to get the proper meaning are no longer required.
71 You now only need to quote strings in configuration files if you literally
72 want quotation marks within a string.
74 * Any applications run that contain the pipe symbol but not a comma symbol will
75 get a warning printed to the effect that the application delimiter has changed.
76 However, there are legitimate reasons why this might be useful in certain
77 situations, so this warning can be turned off with the dontwarn option in
80 * The logger.conf option 'rotatetimestamp' has been deprecated in favor of
81 'rotatestrategy'. This new option supports a 'rotate' strategy that more
82 closely mimics the system logger in terms of file rotation.
84 * The concise versions of various CLI commands are now deprecated. We recommend
85 using the manager interface (AMI) for application integration with Asterisk.
89 * The voicemail configuration values 'maxmessage' and 'minmessage' have
90 been changed to 'maxsecs' and 'minsecs' to clarify their purpose and
91 to make them more distinguishable from 'maxmsgs', which sets folder
92 size. The old variables will continue to work in this version, albeit
93 with a deprecation warning.
95 * If you use any interface for modifying voicemail aside from the built in
96 dialplan applications, then the option "pollmailboxes" *must* be set in
97 voicemail.conf for message waiting indication (MWI) to work properly. This
98 is because Voicemail notification is now event based instead of polling
99 based. The channel drivers are no longer responsible for constantly manually
100 checking mailboxes for changes so that they can send MWI information to users.
101 Examples of situations that would require this option are web interfaces to
102 voicemail or an email client in the case of using IMAP storage.
107 * ChanIsAvail() now has a 't' option, which allows the specified device
108 to be queried for state without consulting the channel drivers. This
109 performs mostly a 'ChanExists' sort of function.
111 * ChannelRedirect() will not terminate the channel that fails to do a
112 channelredirect as it has done previously. Instead CHANNELREDIRECT_STATUS
113 will reflect if the attempt was successful of not.
115 * SetCallerPres() has been replaced with the CALLERPRES() dialplan function
116 and is now deprecated.
118 * DISA()'s fifth argument is now an options argument. If you have previously
119 used 'NOANSWER' in this argument, you'll need to convert that to the new
122 * Macro() is now deprecated. If you need subroutines, you should use the
123 Gosub()/Return() applications. To replace MacroExclusive(), we have
124 introduced dialplan functions LOCK(), TRYLOCK(), and UNLOCK(). You may use
125 these functions in any location where you desire to ensure that only one
126 channel is executing that path at any one time. The Macro() applications
127 are deprecated for performance reasons. However, since Macro() has been
128 around for a long time and so many dialplans depend heavily on it, for the
129 sake of backwards compatibility it will not be removed . It is also worth
130 noting that using both Macro() and GoSub() at the same time is _heavily_
133 * Read() now sets a READSTATUS variable on exit. It does NOT automatically
134 return -1 (and hangup) anymore on error. If you want to hangup on error,
135 you need to do so explicitly in your dialplan.
137 * Privacy() no longer uses privacy.conf, so any options must be specified
138 directly in the application arguments.
140 * MusicOnHold application now has duration parameter which allows specifying
143 * WaitMusicOnHold application is now deprecated in favor of extended MusicOnHold.
145 * SetMusicOnHold is now deprecated. You should use Set(CHANNEL(musicclass)=...)
148 * The arguments in ExecIf changed a bit, to be more like other applications.
149 The syntax is now ExecIf(<cond>?appiftrue(args):appiffalse(args)).
151 * The behavior of the Set application now depends upon a compatibility option,
152 set in asterisk.conf. To use the old 1.4 behavior, which allowed Set to take
153 multiple key/value pairs, set app_set=1.4 in [compat] in asterisk.conf. To
154 use the new behavior, which permits variables to be set with embedded commas,
155 set app_set=1.6 in [compat] in asterisk.conf. Note that you can have both
156 behaviors at the same time, if you switch to using MSet if you want the old
161 * QUEUE_MEMBER_COUNT() has been deprecated in favor of the QUEUE_MEMBER() function. For
162 more information, issue a "show function QUEUE_MEMBER" from the CLI.
166 * The cdr_sqlite module has been marked as deprecated in favor of
167 cdr_sqlite3_custom. It will potentially be removed from the tree
168 after Asterisk 1.6 is released.
170 * The cdr_odbc module now uses res_odbc to manage its connections. The
171 username and password parameters in cdr_odbc.conf, therefore, are no
172 longer used. The dsn parameter now points to an entry in res_odbc.conf.
174 * The uniqueid field in the core Asterisk structure has been changed from a
175 maximum 31 character field to a 149 character field, to account for all
176 possible values the systemname prefix could be. In the past, if the
177 systemname was too long, the uniqueid would have been truncated.
179 * The cdr_tds module now supports all versions of FreeTDS that contain
180 the db-lib frontend. It will also now log the userfield variable if
181 the target database table contains a column for it.
185 * format_wav: The GAIN preprocessor definition and source code that used it
186 is removed. This change was made in response to user complaints of
187 choppiness or the clipping of loud signal peaks. To increase the volume
188 of voicemail messages, use the 'volgain' option in voicemail.conf
192 * SIP: a small upgrade to support the "Record" button on the SNOM360,
193 which sends a sip INFO message with a "Record: on" or "Record: off"
194 header. If Asterisk is set up (via features.conf) to accept "One Touch Monitor"
195 requests (by default, via '*1'), then the user-configured dialpad sequence
196 is generated, and recording can be started and stopped via this button. The
197 file names and formats are all controlled via the normal mechanisms. If the
198 user has not configured the automon feature, the normal "415 Unsupported media type"
199 is returned, and nothing is done.
201 * SIP: The "call-limit" option is marked as deprecated. It still works in this version of
202 Asterisk, but will be removed in the following version. Please use the groupcount functions
203 in the dialplan to enforce call limits. The "limitonpeer" configuration option is
204 now renamed to "counteronpeer".
206 * SIP: The "username" option is now renamed to "defaultuser" to match "defaultip".
207 These are used only before registration to call a peer with the uri
208 sip:defaultuser@defaultip
209 The "username" setting still work, but is deprecated and will not work in
210 the next version of Asterisk.
212 * SIP: The old "insecure" options, deprecated in 1.4, have been removed.
213 "insecure=very" should be changed to "insecure=port,invite"
214 "insecure=yes" should be changed to "insecure=port"
215 Be aware that some telephony providers show the invalid syntax in their
216 sample configurations.
218 * chan_local.c: the comma delimiter inside the channel name has been changed to a
219 semicolon, in order to make the Local channel driver compatible with the comma
220 delimiter change in applications.
222 * H323: The "tos" setting has changed name to "tos_audio" and "cos" to "cos_audio"
223 to be compatible with settings in sip.conf. The "tos" and "cos" configuration
224 is deprecated and will stop working in the next release of Asterisk.
226 * Console: A new console channel driver, chan_console, has been added to Asterisk.
227 This new module can not be loaded at the same time as chan_alsa or chan_oss. The
228 default modules.conf only loads one of them (chan_oss by default). So, unless you
229 have modified your modules.conf to not use the autoload option, then you will need
230 to modify modules.conf to add another "noload" line to ensure that only one of
231 these three modules gets loaded.
233 * DAHDI: The chan_zap module that supported PSTN interfaces using
234 Zaptel has been renamed to chan_dahdi, and only supports the DAHDI
235 telephony driver package for PSTN interfaces. See the
236 Zaptel-to-DAHDI.txt file for more details on this transition.
238 * DAHDI: The "msdstrip" option has been deprecated, as it provides no value over
239 the method of stripping digits in the dialplan using variable substring syntax.
243 * pbx_dundi.c: tos parameter changed to use new values. Old values like lowdelay,
244 lowcost and other is not acceptable now. Look into qos.tex for description of
247 * queues.conf: the queue-lessthan sound file option is no longer available, and the
248 queue-round-seconds option no longer takes '1' as a valid parameter.
252 * Manager has been upgraded to version 1.1 with a lot of changes.
253 Please check doc/manager_1_1.txt for information
255 * The IAXpeers command output has been changed to more closely resemble the
256 output of the SIPpeers command.
258 * cdr_manager now reports at the "cdr" level, not at "call" You may need to
259 change your manager.conf to add the level to existing AMI users, if they
260 want to see the CDR events generated.
262 * The Originate command now requires the Originate write permission. For
263 Originate with the Application parameter, you need the additional System
264 privilege if you want to do anything that calls out to a subshell.
268 * Previously, the Asterisk source code distribution included the iLBC
269 encoder/decoder source code, from Global IP Solutions
270 (http://www.gipscorp.com). This code is not licensed for
271 distribution, and thus has been removed from the Asterisk source
272 code distribution. If you wish to use codec_ilbc to support iLBC
273 channels in Asterisk, you can run the contrib/scripts/get_ilbc_source.sh
274 script to download the source and put it in the proper place in
275 the Asterisk build tree. Once that is done you can follow your normal
276 steps of building Asterisk. You will need to run 'menuselect' and enable
277 the iLBC codec in the 'Codec Translators' category.
