    *Deferreds

    According to the documentation above, bridge_channel needs to be locked prior to calling this function.



/trunk/main/bridging.c
<https://reviewboard.asterisk.org/r/1902/#comment11579>

    Ditto.



/trunk/main/bridging.c
<https://reviewboard.asterisk.org/r/1902/#comment11580>

    On two back to back deferreds, this condition will be false and the channel will exit the bridge unexpectedly.

> Currently, most actions that are executed upon a channel in a conference (increasing/decreasing listening volume, playing back a sound on a channel, etc.) are handled via DTMF menus associated with a user profile.  While this suffices for scenarios where a user initiates an action upon themselves, it does not account for scenarios where a third party application wants to interact with the channels in a ConfBridge.  While there are a handful of AMI commands that allow for external interaction with the channels in the conference, they are currently limited to a subset of the defined actions.

This lets a user of the bridging layer defer execution of some function until such a time that the bridging layer determines that it is safe to execute that action on the channel's thread.

The channel was properly suspended from the bridging layer, the playback confbridge action was executed, and the channel was placed back into the bridging layer.  All of this was similar to what would occur if the same action was triggered using a DTMF menu.
