Richard Mudgett a5b9b792ea Avoid a stale pointer crash if the TE BRI TEI is removed when active calls exist. 
Made the q931_call record point to the master D channel control structure
instead of the BRI TEI subchannel control structure.  When a layer 3 message
is sent, the current TEI subchannel control structure is used.

libpri: An implementation of Primary Rate ISDN

Written by Mark Spencer <markster@digium.com>

What is libpri?
===============

libpri is a C implementation of the Primary Rate ISDN specification.  It was
based on the Bellcore specification SR-NWT-002343 for National ISDN.  As of
May 12, 2001, it has been tested work with NI-2, Nortel DMS-100, and 
Lucent 5E Custom protocols on switches from Nortel and Lucent.

What is the license for libpri?
===============================
libpri is distributed under the terms of the GNU General Public License, 
which permit its use and linking with other GPL'd software only.  
The GNU GPL is included in the file LICENSE in this directory.

As a special exception, libpri may also be linked to the OpenH323
library, so long as the entirity of the derivative work (as defined
within the GPL) is licensed either under the MPL of the OpenH323 license
or the GPL of libpri.

If you wish to use libpri in an application for which the GPL is not 
appropriate (e.g. a proprietary embedded system), licenses for libpri 
under more flexible terms can be readily obtained through Digium, Inc. 
at reasonable cost.


How do I report bugs or contribute?
===================================
For now, contact the author directly.  In the future if there is 
sufficient interest, we will setup a mailing list.

Does anything use this library so far?
======================================
Yes, the Asterisk Open Source PBX does.  http://www.asterisk.org

Also, the Zapata library has hooks for it.  http://www.zapatatelephony.org

Special thanks
==============
Special thanks to Jim Dixon <jim@lambdatel.com> for his help in 
testing and fixing the implementation.
