             Summary: Bridge API Enhancements - add CHANNEL(after-bridge-goto) feature
                 Key: ASTERISK-21880
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21880
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Core/Bridging
            Reporter: Matt Jordan
      Target Release: 12


When channels are released from a bridge, there are three options available to them:
* Be hung up (which is the default)
* Go to a particular dialplan location. This is typically set by the Bridge/Dial applications.
* Execute a C callback function (internal implementation detail)

Of the second, it would be highly desirable to have the after-bridge location be set through the CHANNEL function. Channels have the ability to bridged in a variety of ways, and allowing a function to set the property removes the need for adding specific application fields to a large class of applications.

The syntax should be:

{{CHANNEL(after-bridge-goto)=[context,[exten]],priority}}

Where {{context,exten,priority}} follows the parseable goto format (allowing for specification of only priority, etc.)

*NOTE*

This addresses the following *BUGBUG* comment in trunk:
{{./funcs/func_channel.c: * BUGBUG add CHANNEL(after_bridge_goto)=<parseable-goto> Sets an after bridge goto datastore property on the channel.}}
