Asterisk v1.2.0 upgrade

Information for Upgrading From Previous Asterisk Releases

Copied from UPGRADE.txt of Asterisk v1.2.0


The Asterisk 1.2 source code now uses C language features
supported only by 'modern' C compilers. Generally, this means GCC
version 3.0 or higher, although some GCC 2.96 releases will also
work. Some non-GCC compilers that support C99 and the common GCC
extensions (including anonymous structures and unions) will also
work. All releases of GCC 2.95 do _not_ have the requisite feature
support; systems using that compiler will need to be upgraded to
a more recent compiler release.

Dialplan Expressions:

The dialplan expression parser (which handles $[ ... ] constructs)
has gone through a major upgrade, but has one incompatible change:
spaces are no longer required around expression operators, including
string comparisons. However, you can now use quoting to keep strings
together for comparison. For more details, please read the
doc/README.variables file, and check over your dialplan for possible


The default for ackcall has been changed to "no" instead of "yes"
because of a bug which caused the "yes" behavior to generally act like
"no". You may need to adjust the value if your agents behave
differently than you expect with respect to acknowledgement.

The AgentCallBackLogin application now requires a second '|' before
specifying an extension@context. This is to distinguish the options
string from the extension, so that they do not conflict. See
'show application AgentCallbackLogin' for more details.


Parking behavior has changed slightly; when a parked call times out,
Asterisk will attempt to deliver the call back to the extension that
parked it, rather than the 's' extension. If that extension is busy
or unavailable, the parked call will be lost.


The Caller*ID of the outbound leg is now the extension that was
called, rather than the Caller*ID of the inbound leg of the call. The
"o" flag for Dial can be used to restore the original behavior if
desired. Note that if you are looking for the originating callerid
from the manager event, there is a new manager event "Dial" which
provides the source and destination channels and callerid.


The naming convention for IAX channels has changed in a minor way such
that the call number follows a "-" rather than a "/" character.


The global option "port" in 1.0.X that is used to set which port to
bind to has been changed to "bindport" to be more consistent with
the other channel drivers and to avoid confusion with the "port"
option for users/peers.

The "Registry" event now uses "Username" rather than "User" for
consistency with IAX.


With the addition of dialplan functions (which operate similarly
to variables), the SetVar application has been renamed to Set.

The CallerPres application has been removed. Use SetCallerPres
instead. It accepts both numeric and symbolic names.

The applications GetGroupCount, GetGroupMatchCount, SetGroup, and
CheckGroup have been deprecated in favor of functions. Here is a
table of their replacements:

GetGroupCount([groupname][@category] GROUP_COUNT([groupname][@category]) Set(GROUPCOUNT=${GROUP_COUNT()})
GroupMatchCount(groupmatch[@category]) GROUP_MATCH_COUNT(groupmatch[@category]) Set(GROUPCOUNT=${GROUP_MATCH_COUNT(SIP/.*)})
SetGroup(groupname[@category]) GROUP([category])=groupname Set(GROUP()=test)
CheckGroup(max[@category]) N/A GotoIf($[ ${GROUP_COUNT()} > 5 ]?103)

Note that CheckGroup does not have a direct replacement. There is
also a new function called GROUP_LIST() which will return a space
separated list of all of the groups set on a channel. The GROUP()
function can also return the name of the group set on a channel when
used in a read environment.

The applications DBGet and DBPut have been deprecated in favor of
functions. Here is a table of their replacements:

DBGet(foo=family/key) Set(foo=${DB(family/key)})
DBPut(family/key=${foo}) Set(DB(family/key)=${foo})

The application SetLanguage has been deprecated in favor of the
function LANGUAGE().

SetLanguage(fr) Set(LANGUAGE()=fr)

The LANGUAGE function can also return the currently set language:


The applications AbsoluteTimeout, DigitTimeout, and ResponseTimeout
have been deprecated in favor of the function TIMEOUT(timeouttype):

AbsoluteTimeout(300) Set(TIMEOUT(absolute)=300)
DigitTimeout(15) Set(TIMEOUT(digit)=15)
ResponseTimeout(15) Set(TIMEOUT(response)=15)

The TIMEOUT() function can also return the currently set timeouts:


The applications SetCIDName, SetCIDNum, and SetRDNIS have been
deprecated in favor of the CALLERID(datatype) function:

SetCIDName(Joe Cool) Set(CALLERID(name)=Joe Cool)
SetCIDNum(2025551212) Set(CALLERID(number)=2025551212)
SetRDNIS(2024561414) Set(CALLERID(RDNIS)=2024561414)

The application Record now uses the period to separate the filename
from the format, rather than the colon.

The application VoiceMail now supports a 'temporary' greeting for each
mailbox. This greeting can be recorded by using option 4 in the
'mailbox options' menu, and 'change your password' option has been
moved to option 5.


A queue is now considered empty not only if there are no members but if
none of the members are available (e.g. agents not logged on). To
restore the original behavior, use "leavewhenempty=strict" or
"joinwhenempty=strict" instead of "=yes" for those options.

It is now possible to use multi-digit extensions in the exit context
for a queue (although you should not have overlapping extensions,
as there is no digit timeout). This means that the EXITWITHKEY event
in queue_log can now contain a key field with more than a single
character in it.


By default, there is a new option called "autofallthrough" in
extensions.conf that is set to yes. Asterisk 1.0 (and earlier)
behavior was to wait for an extension to be dialed after there were no
more extensions to execute. "autofallthrough" changes this behavior
so that the call will immediately be terminated with BUSY,
CONGESTION, or HANGUP based on Asterisk's best guess. If you are
writing an extension for IVR, you must use the WaitExten application
if "autofallthrough" is set to yes.


AGI scripts did not always get SIGHUP at the end, previously. That
behavior has been fixed. If you do not want your script to terminate
at the end of AGI being called (e.g. on a hangup) then set SIGHUP to
be ignored within your application.

CallerID is reported with agi_callerid and agi_calleridname instead
of a single parameter holding both.

Music On Hold:

The preferred format for musiconhold.conf has changed; please see the
sample configuration file for the new format. The existing format
is still supported but will generate warnings when the module is loaded.


All the chan_modem channel drivers (aopen, bestdata and i4l) are deprecated
in this release, and will be removed in the next major Asterisk release.
Please migrate to chan_misdn for ISDN interfaces; there is no upgrade
path for aopen and bestdata modem users.


The conference application now allows users to increase/decrease their
speaking volume and listening volume (independently of each other and
other users); the 'admin' and 'user' menus have changed, and new sound
files are included with this release. However, if a user calling in
over a Zaptel channel that does NOT have hardware DTMF detection
increases their speaking volume, it is likely they will no longer be
able to enter/exit the menu or make any further adjustments, as the
software DTMF detector will not be able to recognize the DTMF coming
from their device.

GetVar Manager Action:

Previously, the behavior of the GetVar manager action reported the value
of a variable in the following manner:

> name: value

This has been changed to a manner similar to the SetVar action and is now

> Variable: name
> Value: value

Go back to Asterisk v1.2
