Author: rmudgett
Date: Wed Jan 20 14:02:48 2010
New Revision: 1434

URL: http://svnview.digium.com/svn/libpri?view=rev&rev=1434
Log:
Make PTMP agent be more tollerant of no response to CCBSStatusRequest.

Do not cancel CC if we simply get no responses to a CCBSStatusRequest.  We
will cancel if we do not get any responses for RAW_STATUS_COUNT_MAX times.
