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.

I think the deadlock issue you are referring to is already avoided in the
current branch code.  There are three locks involved:
1) PRI access lock
2) sig_pri/chan_dahdi private lock.
3) channel lock
The function sig_pri_lock_owner() goes through deadlock avoidance to
obtain the third lock if the owner pointer is not null.
