New Revision: 39109

URL: http://svn.digium.com/view/asterisk?rev=39109&view=rev
Log:
Merge my applicationmap_fixup branch to address the issues described in this
post to the asterisk-dev mailing list:
  http://lists.digium.com/pipermail/asterisk-dev/2006-August/022174.html

This implements full control over both which channel(s) can activate a dynamic
feature, as well as which channel to run the application on.  I also updated
the documentation on the applicationmap in features.conf.sample in hopes that
the configuration is more clear.

 ; Note that the DYNAMIC_FEATURES channel variable must be set to use the features
 ; defined here.  The value of DYNAMIC_FEATURES should be the names of the features
 ; to allow the channel to use separated by '#'.  For example:
+;
 ;    Set(DYNAMIC_FEATURES=myfeature1#myfeature2#myfeature3)
 ;
-;testfeature => #9,callee,Playback,tt-monkeys	;Play tt-monkeys to 
-						;callee if #9 was pressed
-;pauseMonitor   => #1,caller,Pausemonitor	;Pause monitoring on channel
-;unpauseMonitor => #3,caller,UnPauseMonitor	;Unpause monitoring on channel
+;
+; The syntax for declaring a dynaic feature is the following:
+;
+;<FeatureName> => <DTMF_sequence>,<ActivateOn>[/<ActivatedBy>],<Application>[,<AppArguments>]
+;
+;  FeatureName   -> This is the name of the feature used in when setting the
+;                   DYNAMIC_FEATURES variable to enable usage of this feature.
+;  DTMF_sequence -> This is the key sequence used to activate this feature.
+;  ActivateOn    -> This is the channel of the call that the application will be executed
+;                   on. Valid values are "self" and "peer". "self" means run the
+;                   application on the same channel that activated the feature. "peer"
+;                   means run the application on the opposite channel from the one that
+;                   has activated the feature.
+;  ActivatedBy   -> This is which channel is allowed to activated this feature. Valid
+;                   values are "caller", "callee", and "both". "both" is the default.
+;                   The "caller" is the channel that executed the Dial application, while
+;                   the "callee" is the channel called by the Dial application.
+;  Application   -> This is the application to execute.
+;  AppArguments  -> These are the arguments to be passed into the application.
+;
+;
+; IMPORTANT NOTE: The applicationmap is not intended to be used for all Asterisk
+;   applications. When applications are used in extensions.conf, they are executed
+;   by the PBX core. In this case, these applications are executed outside of the
+;   PBX core, so it does *not* make sense to use any application which has any
+;   concept of dialplan flow. Examples of this would be things like Macro, Goto,
+;   Background, WaitExten, and many more.
+;
+;
+; Example Usage:
+;
+;testfeature => #9,peer,Playback,tt-monkeys  ;Allow both the caller and callee to play
+;                                            ;tt-monkeys to the opposite channel
+;
+;pauseMonitor   => #1,self/callee,Pausemonitor     ;Allow the callee to pause monitoring
+;                                                  ;on their channel
+;unpauseMonitor => #3,self/callee,UnPauseMonitor   ;Allow the callee to unpause monitoring
+;                                                  ;on their channel
