[SVN commits to the Asterisk project]

New Revision: 349144

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=349144
Log:
Once an audiohook is attached to a channel, we continue to transcode all of the
frames, even after all of the hooks are detached.  This patch short-cicuits us
out before we transcode unnecessarily.
