+=== Information for upgrading from Asterisk 1.0 to 1.2
+=== UPGRADE-1.2.txt -- Upgrade info for 1.0 to 1.2
+=== UPGRADE-1.4.txt -- Upgrade info for 1.2 to 1.4
+=== UPGRADE.txt -- Upgrade info for 1.4 to 1.6
+* 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
+ problems.
+* 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 two ways:
+ 1. The call number follows a "-" rather than a "/" character.
+ 2. The name of the channel has been simplified to IAX2/peer-callno,
+ rather than IAX2/peer@peer-callno or even IAX2/peer@peer/callno.
+* 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:
+ Set(DTIMEOUT=${TIMEOUT(digit)})
+* 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.
+* The application VoiceMailMain now only matches the 'default' context if
+ none is specified in the arguments. (This was the previously
+ documented behavior, however, we didn't follow that behavior.) The old
+ behavior can be restored by setting searchcontexts=yes in voicemail.conf.
+* 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
