Status
------

This change has been marked as submitted.


Review request for Asterisk Developers and kmoore.


Bugs: ASTERISK-22749
    https://issues.asterisk.org/jira/browse/ASTERISK-22749


Repository: Asterisk


Description
-------

This contains the patch on the issue (submitted by kmoore), as well as the fix for the adding in a bridge lock while calling bridge_start from the framehook callback.  Since the framehook callback is not called from the bridging core the bridge is not locked, but needs to be before calling bridge_start.  The addition to the given patch adds in the necessary bridge locking in order to avoid a deadlock.

Testing
-------

Added channels via DTMF attended transfer to get to a 4-way bridge and then removed them and noted all channels and the bridge had been torn down.


Thanks,

Kevin Harwell
