New Revision: 18023
URL: http://svn.digium.com/view/asterisk?rev=18023&view=rev
Log:
Fix a problem where if the channel was hungup during detection, the application wouldn't block indefinitely looking for another frame from that channel. Don't try to do frame size analysis on a frame that isn't voice, only report DEBUG and VERBOSE msgs to the logger channels when the DEBUG and VERBOSE settings are high enough to require it, and some other minor cleanups.
