Richard Mudgett b698032e04 Reimplement callback mechanism to handle APDU response messages that we care about. 
1) No sent messages will remain in the APDU queue unless they have an
active timer to remove them.  The dummy call reference call and global
call reference call structures will not act like a memory leak to sent
messages.

2) The new T-RESPONSE timer will be the generic response guard if the
standards do not otherwise specify a timer for a message response.

3) The callback will be called.  If it is called because of a response
message, then the callback has an opportunity to indicate if more
responses are expected.

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.
