At the request of ManxPower, include the UPGRADE.txt from 1.2 and 1.4, as well.
This way, if people need to go back and review what was deprecated in previous major releases, it is readily available to them. Thanks for the suggestion! git-svn-id: http://svn.digium.com/svn/asterisk/trunk@103044 f38db490-d61c-443f-a65b-d21fe96a405b

+=== 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
