Summary:                    [patch] COLP/CONP support in QSIG
Description: 
There's work in progress at Digium to implement COLP/CONP in asterisk team
branch issue8824 http://svn.digium.com/view/asterisk/team/group/issue8824.
Connected line and number presentation now is also supported in ISDN/QSIG
by two patchfiles attached to this issue.

The number and line presentation not only works for simple calls (for
called and calling party number) but also for call diversion and call
transfer.
This means divertingLegInformation1, divertingLegInformation2,
divertingLegInformation3, callTransferComplete, callTransferActive,
CalledName, ... are supported in QSIG.
It has been tested with HiPath 3000 V4.0 and HICOM 300.

libpri-1.4-2008-12-10-colpconp-0.1.0.patch adds COLP/CONP support to
libpri-1.4 branch. This patch includes lots of new functions for QSIG apdu
encoding and decoding and also fixes some bugs related to QSIG
encoding/encoding.

asterisk-issue8824-2008-12-10-colpconp-0.1.0.patch is used to patch
chan_dahdi.c in asterisk-issue8824.

All of this work seems to be related to Asterisk providing a QSIG network,
and QSIG pinx's as CPE's to Asterisk.

What about turning this around, we have JTEC equipment that provides a
QSIG network between all of our sites, and have Asterisk at each site as a
QSIG CPE. The main issue for us, is calls trombone between sites if they
are transferred back to the orignal site, "QSIG - Call Path Replacement".

A simple test setup might be 2 Asterisk boxes connected back to back, with
an E1/T1 card, one configured as QSIG CPE and the other QSIG NET. Then
initiate a call from SiteA->SiteB, then from SiteB transfer back to SiteA,
ideally no calls should exist on the E1/T1 circuit after the transfer.
