Playing back a file to a channel in a conference

You might notice in this application that while playing a sound file to a channel the actual conference bridge lock is not held. This is done so that other channels are not blocked from interacting with the conference bridge. Unfortunately because of this it is possible for things to change after the sound file is done being played. Data must therefore be checked after reacquiring the conference bridge lock if it is important.
