             Summary: Using AMI Action Bridge to on an already bridged channel causes the incorrect return priority to be used
                 Key: ASTERISK-24529
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24529
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/Bridging
    Affects Versions: 13.0.0, 12.7.0, SVN
            Reporter: Corey Farrell
            Severity: Minor


When using "Action: Bridge" on two channels in dialplan, after one channel hangs up, the other normally goes to the next priority in dialplan.  For example use this method to bridge channel 1 and 2, then bridge channel 1 and 3.  When channel 1 is removed from the first bridge, channel 2 will be sent to the next priority in dialplan.  If channel 3 hangs up before channel 2, channel 2 will by sent to the same priority it originally came from.  Found through testsuite: tests/bridge/bridge_action, channel 3 goes back to Echo() at the end of the test and never hangs up.

This is related to {{AST_FLAG_IN_AUTOLOOP}}.  When the channel is in a dialplan app and "Action: Bridge" is run, it tells the bridge that the return priority should be current + 1.  The flag is set while the channel is within {{__ast_pbx_run}}, but not when the channel is already in a bridge initiated by AMI.  So when the channel is rebridged it does nothing causes dialplan to advance to the next priority.
