[SVN commits to the libpri project]

Author: mattf
Date: Tue Jul 21 17:11:48 2009
New Revision: 947

URL: http://svn.asterisk.org/svn-view/libpri?view=rev&rev=947
Log:
Fix bidirectional calling so that it works again... the pri for the call has to be set every time we receive a message, not just when we create a new call.
