Summary:                    [patch] CCBS/CCNR support for QSIG (libpri &
chan_dahdi)
Description: 
Based on the COLP/CONP work in asterisk team branch issue8824
http://svn.digium.com/view/asterisk/team/group/issue8824 and the QSIG
COLP/CONP patch in issue 0014068 here comes another patch for chan_dahdi &
libpri regarding the ISDN/QSIG CCBS/CCNR feature.

Since there is some basic stuff done in issue 0014068 regarding QSIG
facility handling in libpri and chan_dahdi the patches requires the patches
from issue 0014068 first.

It has been tested with HiPath 3000 V4.0 and HICOM 300.

libpri-1.4-2008-12-10-ccbsccnr-0.1.0.patch adds CCBS/CCNR support to
libpri-1.4 branch. 
asterisk-issue8824-2008-12-10-ccbsccnr-0.1.0.patch is used to patch
chan_dahdi.c in asterisk-issue8824. 

QSIG CCBS-CCNR.doc is a short description of the new dahdi dialplan
applications and gives information how to use them in the dialplan.

---------------------------------------------------------------------- 
One other feature related fix:
The COLP/CONP information of a SIP ringing (e.g. P-Asserted-Header) was
not mapped to an QSIG Alerted Name Facility, if a QSIG/Q.931 Call
Proceeding was sent out before towards ISDN (e.g. using Proceeding()
application in dialplan)

Fix see send_qsig_alertingname.patch


One Request:
Please port the SIP UPDATE handling extension of ABE this branch in near
future!

Another Request:
It would be nice to have the ability to deactivate call forwarding in case
of a SIP 482 Loop Detect response.

AddOn:
To allow partial rerouting from SIP to QSIG we implemented a patch to do
so.
Abstract: A SIP 301/302 response 'moved temporarely' does not
automatically invoke * call forwarding (internal forward switching) but
returns to dialplan where a astdb parameter can be read
(diverted-to-number). Calling the QSIG Call Rerouting Feature at this point
does the rest.
This helps nicely to suppress ugly call loops ...
