[asterisk-commits] mmichelson: branch mmichelson/queue_bugbug r394456 - /team/mmichelson/queue_b...

[SVN commits to the Asterisk project]

Author: mmichelson
Date: Tue Jul 16 11:55:19 2013
New Revision: 394456

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=394456
Log:
Add initial naive hangup detection for queue calls.

This will need some major adjustments once local optimization
is taken into account, but for simple calls, this currently
works fine.
