[SVN commits to the libpri project]

Author: rmudgett
Date: Wed Feb  9 13:51:19 2011
New Revision: 2198

URL: http://svnview.digium.com/svn/libpri?view=rev&rev=2198
Log:
The called number did not go out in the FACILITY message.

* Fix sending called number ie in FACILITY message.  The called number
needs to be staged in the call->overlap_digits string.

* Protect the call->called.number.str when receiving the called number in
an unexpected message.
