Information for Upgrading From Previous Asterisk Releases
=========================================================
Command Line Interface:
* 'show channels concise', designed to be used by applications that will parse
its output, previously used ':' characters to separate fields. However, some
of those fields can easily contain that character, making the output not
parseable. The delimiter has been changed to '!'.
Applications:
* In previous Asterisk releases, many applications would jump to priority n+101
to indicate some kind of status or error condition. This functionality was
marked deprecated in Asterisk 1.2. An option to disable it was provided with
the default value set to 'on'. The default value for the global priority
jumping option is now 'off'.
* The applications Cut, Sort, DBGet, DBPut, SetCIDNum, SetCIDName, SetRDNIS,
AbsoluteTimeout, DigitTimeout, ResponseTimeout, SetLanguage, GetGroupCount,
and GetGroupMatchCount were all deprecated in version 1.2, and therefore have
been removed in this version. You should use the equivalent dialplan
function in places where you have previously used one of these applications.
* The application SetVar has been renamed to Set. The syntax SetVar was marked
deprecated in version 1.2 and is no longer recognized in this version.
* app_read has been updated to use the newer options codes, using "skip" or
"noanswer" will not work. Use s or n. Also there is a new feature i, for
using indication tones, so typing in skip would give you unexpected results.
Variables:
* The builtin variables ${CALLERID}, ${CALLERIDNAME}, ${CALLERIDNUM},
${CALLERANI}, ${DNID}, ${RDNIS}, ${DATETIME}, ${TIMESTAMP}, ${ACCOUNTCODE},
and ${LANGUAGE} have all been deprecated in favor of their related dialplan
functions. You are encouraged to move towards the associated dialplan
function, as these variables will be removed in a future release.
Functions:
* The function ${CHECK_MD5()} has been deprecated in favor of using an
expression: $[${MD5(<string>)} = ${saved_md5}].
* The 'builtin' functions that used to be combined in pbx_functions.so are
now built as separate modules. If you are not using 'autoload=yes' in your
modules.conf file then you will need to explicitly load the modules that
contain the functions you want to use.
* The ENUMLOOKUP() function no longer supplies a default zone for searching; instead,
it uses the default zone(s) defined in enum.conf. In addition, when the 'c'
option (for counting the number of records is specified), but the lookup fails
to match any records, the returned value will now be "0" instead of blank.
The SIP channel:
* The "incominglimit" setting is replaced by the "call-limit" setting in sip.conf.
Installation:
* On BSD systems, the installation directories have changed to more "FreeBSDish" directories. On startup, Asterisk will look for the main configuration in /usr7local/etc/asterisk/asterisk.conf
If you have an old installation, you might want to remove the binaries and move the configuration files to the new locations. The following directories are now default:
ASTLIBDIR /usr/local/lib/asterisk
ASTVARLIBDIR /usr/local/share/asterisk
ASTETCDIR /usr/local/etc/asterisk
ASTBINDIR /usr/local/bin/asterisk
ASTSBINDIR /usr/local/sbin/asterisk
