=========================================================
===
=== Information for upgrading from Asterisk 1.4 to 1.6
===
=== These files document all the changes that MUST be taken
=== into account when upgrading between the Asterisk
=== versions listed below. These changes may require that
=== you modify your configuration files, dialplan or (in
=== some cases) source code if you have your own Asterisk
=== modules or patches. These files also includes advance
=== notice of any functionality that has been marked as
=== 'deprecated' and may be removed in a future release,
=== along with the suggested replacement functionality.
===
=== UPGRADE-1.2.txt -- Upgrade info for 1.0 to 1.2
=== UPGRADE-1.4.txt -- Upgrade info for 1.2 to 1.4
===
=========================================================
AEL:
* Macros are now implemented underneath with the Gosub() application.
Heaven Help You if you wrote code depending on any aspect of this!
Previous to 1.6, macros were implemented with the Macro() app, which
provided a nice feature of auto-returning. The compiler will do its
best to insert a Return() app call at the end of your macro if you did
not include it, but really, you should make sure that all execution
paths within your macros end in "return;".
* The conf2ael program is 'introduced' in this release; it is in a rather
crude state, but deemed useful for making a first pass at converting
extensions.conf code into AEL. More intelligence will come with time.
Core:
* The 'languageprefix' option in asterisk.conf is now deprecated, and
the default sound file layout for non-English sounds is the 'new
style' layout introduced in Asterisk 1.4 (and used by the automatic
sound file installer in the Makefile).
* The ast_expr2 stuff has been modified to handle floating-point numbers.
Numbers of the format D.D are now acceptable input for the expr parser,
Where D is a string of base-10 digits. All math is now done in "long double",
if it is available on your compiler/architecture. This was half-way between
a bug-fix (because the MATH func returns fp by default), and an enhancement.
Also, for those counting on, or needing, integer operations, a series of
'functions' were also added to the expr language, to allow several styles
of rounding/truncation, along with a set of common floating point operations,
like sin, cos, tan, log, pow, etc. The ability to call external functions
like CDR(), etc. was also added, without having to use the ${...} notation.
* The delimiter passed to applications has been changed to the comma (','), as
that is what people are used to using within extensions.conf. If you are
using realtime extensions, you will need to translate your existing dialplan
to use this separator. To use a literal comma, you need merely to escape it
with a backslash ('\'). Another possible side effect is that you may need to
remove the obscene level of backslashing that was necessary for the dialplan
to work correctly in 1.4 and previous versions. This should make writing
dialplans less painful in the future, albeit with the pain of a one-time
conversion. If you would like to avoid this conversion immediately, set
pbx_realtime=1.4 in the [compat] section of asterisk.conf. After
transitioning, set pbx_realtime=1.6 in the same section.
* For the same purpose as above, you may set res_agi=1.4 in the [compat]
section of asterisk.conf to continue to use the '|' delimiter in the EXEC
arguments of AGI applications. After converting to use the ',' delimiter,
change this option to res_agi=1.6.
* As a side effect of the application delimiter change, many places that used
to need quotes in order to get the proper meaning are no longer required.
You now only need to quote strings in configuration files if you literally
want quotation marks within a string.
* Any applications run that contain the pipe symbol but not a comma symbol will
get a warning printed to the effect that the application delimiter has changed.
However, there are legitimate reasons why this might be useful in certain
situations, so this warning can be turned off with the dontwarn option in
asterisk.conf.
* The logger.conf option 'rotatetimestamp' has been deprecated in favor of
'rotatestrategy'. This new option supports a 'rotate' strategy that more
closely mimics the system logger in terms of file rotation.
* The concise versions of various CLI commands are now deprecated. We recommend
using the manager interface (AMI) for application integration with Asterisk.
Voicemail:
* The voicemail configuration values 'maxmessage' and 'minmessage' have
been changed to 'maxsecs' and 'minsecs' to clarify their purpose and
to make them more distinguishable from 'maxmsgs', which sets folder
size. The old variables will continue to work in this version, albeit
with a deprecation warning.
* If you use any interface for modifying voicemail aside from the built in
dialplan applications, then the option "pollmailboxes" *must* be set in
voicemail.conf for message waiting indication (MWI) to work properly. This
is because Voicemail notification is now event based instead of polling
based. The channel drivers are no longer responsible for constantly manually
checking mailboxes for changes so that they can send MWI information to users.
Examples of situations that would require this option are web interfaces to
voicemail or an email client in the case of using IMAP storage.
Applications:
* ChanIsAvail() now has a 't' option, which allows the specified device
to be queried for state without consulting the channel drivers. This
performs mostly a 'ChanExists' sort of function.
* ChannelRedirect() will not terminate the channel that fails to do a
channelredirect as it has done previously. Instead CHANNELREDIRECT_STATUS
will reflect if the attempt was successful of not.
* SetCallerPres() has been replaced with the CALLERPRES() dialplan function
and is now deprecated.
* DISA()'s fifth argument is now an options argument. If you have previously
used 'NOANSWER' in this argument, you'll need to convert that to the new
option 'n'.
* Macro() is now deprecated. If you need subroutines, you should use the
Gosub()/Return() applications. To replace MacroExclusive(), we have
introduced dialplan functions LOCK(), TRYLOCK(), and UNLOCK(). You may use
these functions in any location where you desire to ensure that only one
channel is executing that path at any one time. The Macro() applications
are deprecated for performance reasons. However, since Macro() has been
around for a long time and so many dialplans depend heavily on it, for the
sake of backwards compatibility it will not be removed . It is also worth
noting that using both Macro() and GoSub() at the same time is _heavily_
discouraged.
* Read() now sets a READSTATUS variable on exit. It does NOT automatically
return -1 (and hangup) anymore on error. If you want to hangup on error,
you need to do so explicitly in your dialplan.
* Privacy() no longer uses privacy.conf, so any options must be specified
directly in the application arguments.
* MusicOnHold application now has duration parameter which allows specifying
timeout in seconds.
* WaitMusicOnHold application is now deprecated in favor of extended MusicOnHold.
* SetMusicOnHold is now deprecated. You should use Set(CHANNEL(musicclass)=...)
instead.
* The arguments in ExecIf changed a bit, to be more like other applications.
The syntax is now ExecIf(<cond>?appiftrue(args):appiffalse(args)).
* The behavior of the Set application now depends upon a compatibility option,
set in asterisk.conf. To use the old 1.4 behavior, which allowed Set to take
multiple key/value pairs, set app_set=1.4 in [compat] in asterisk.conf. To
use the new behavior, which permits variables to be set with embedded commas,
set app_set=1.6 in [compat] in asterisk.conf. Note that you can have both
behaviors at the same time, if you switch to using MSet if you want the old
behavior.
Dialplan Functions:
* QUEUE_MEMBER_COUNT() has been deprecated in favor of the QUEUE_MEMBER() function. For
more information, issue a "show function QUEUE_MEMBER" from the CLI.
CDR:
* The cdr_sqlite module has been marked as deprecated in favor of
cdr_sqlite3_custom. It will potentially be removed from the tree
after Asterisk 1.6 is released.
* The cdr_odbc module now uses res_odbc to manage its connections. The
username and password parameters in cdr_odbc.conf, therefore, are no
longer used. The dsn parameter now points to an entry in res_odbc.conf.
* The uniqueid field in the core Asterisk structure has been changed from a
maximum 31 character field to a 149 character field, to account for all
possible values the systemname prefix could be. In the past, if the
systemname was too long, the uniqueid would have been truncated.
* The cdr_tds module now supports all versions of FreeTDS that contain
the db-lib frontend. It will also now log the userfield variable if
the target database table contains a column for it.
Formats:
* format_wav: The GAIN preprocessor definition and source code that used it
is removed. This change was made in response to user complaints of
choppiness or the clipping of loud signal peaks. To increase the volume
of voicemail messages, use the 'volgain' option in voicemail.conf
Channel Drivers:
* SIP: a small upgrade to support the "Record" button on the SNOM360,
which sends a sip INFO message with a "Record: on" or "Record: off"
header. If Asterisk is set up (via features.conf) to accept "One Touch Monitor"
requests (by default, via '*1'), then the user-configured dialpad sequence
is generated, and recording can be started and stopped via this button. The
file names and formats are all controlled via the normal mechanisms. If the
user has not configured the automon feature, the normal "415 Unsupported media type"
is returned, and nothing is done.
* SIP: The "call-limit" option is marked as deprecated. It still works in this version of
Asterisk, but will be removed in the following version. Please use the groupcount functions
in the dialplan to enforce call limits. The "limitonpeer" configuration option is
now renamed to "counteronpeer".
* SIP: The "username" option is now renamed to "defaultuser" to match "defaultip".
These are used only before registration to call a peer with the uri
sip:defaultuser@defaultip
The "username" setting still work, but is deprecated and will not work in
the next version of Asterisk.
* chan_local.c: the comma delimiter inside the channel name has been changed to a
semicolon, in order to make the Local channel driver compatible with the comma
delimiter change in applications.
* H323: The "tos" setting has changed name to "tos_audio" and "cos" to "cos_audio"
to be compatible with settings in sip.conf. The "tos" and "cos" configuration
is deprecated and will stop working in the next release of Asterisk.
* Console: A new console channel driver, chan_console, has been added to Asterisk.
This new module can not be loaded at the same time as chan_alsa or chan_oss. The
default modules.conf only loads one of them (chan_oss by default). So, unless you
have modified your modules.conf to not use the autoload option, then you will need
to modify modules.conf to add another "noload" line to ensure that only one of
these three modules gets loaded.
* DAHDI: The chan_zap module that supported PSTN interfaces using
Zaptel has been renamed to chan_dahdi, and only supports the DAHDI
telephony driver package for PSTN interfaces. See the
Zaptel-to-DAHDI.txt file for more details on this transition.
* DAHDI: The "msdstrip" option has been deprecated, as it provides no value over
the method of stripping digits in the dialplan using variable substring syntax.
Configuration:
* pbx_dundi.c: tos parameter changed to use new values. Old values like lowdelay,
lowcost and other is not acceptable now. Look into qos.tex for description of
this parameter.
* queues.conf: the queue-lessthan sound file option is no longer available, and the
queue-round-seconds option no longer takes '1' as a valid parameter.
Manager:
* Manager has been upgraded to version 1.1 with a lot of changes.
Please check doc/manager_1_1.txt for information
* The IAXpeers command output has been changed to more closely resemble the
output of the SIPpeers command.
* cdr_manager now reports at the "cdr" level, not at "call" You may need to
change your manager.conf to add the level to existing AMI users, if they
want to see the CDR events generated.
* The Originate command now requires the Originate write permission. For
Originate with the Application parameter, you need the additional System
privilege if you want to do anything that calls out to a subshell.
iLBC Codec:
* Previously, the Asterisk source code distribution included the iLBC
encoder/decoder source code, from Global IP Solutions
(http://www.gipscorp.com). This code is not licensed for
distribution, and thus has been removed from the Asterisk source
code distribution. If you wish to use codec_ilbc to support iLBC
channels in Asterisk, you can run the contrib/scripts/get_ilbc_source.sh
script to download the source and put it in the proper place in
the Asterisk build tree. Once that is done you can follow your normal
steps of building Asterisk. You will need to run 'menuselect' and enable
the iLBC codec in the 'Codec Translators' category.
