Description:Our asterisk box is RJO / OPC 4490. We have 4 SS7 E1s connected to FLO,
BRB, ARC & CDS.
We have a "quasi-permanent" signaling link via channel 16 of FLO and BRB
to PTS SIG-1 and SIG-2.

Bug:
1) When receiving SS7 messages (like GRS, etc.) from BRB, ARC & CDS
(OPCs 4377,4379,4378) , chan_zap replied to FLO (DPC 4132). Also there
is no sigchannel to ARC & CDS and I could not set def_dpc properly
(based on linkset structure). I included DPC information during channel
creation based on value of cur_defdpc variable (see patches and my new
zapata.conf below).

nice job, danbic.

1. Could you please get a disclaimer on file (see bottom of http://bugs.digium.com/main_page.php) and confirm with a note here when done?
2. Combine changes to all files into a single patch, also clean up the comments to only reflect "code comments" -> if you wish your name to appear on the contribution list, please make the respective change to the CREDITS file.

I cleaned up the patches and grouped libss7 patches on one file.

Ok, it's committed into the latest version of trunk.  If you can update to make sure I applied everything correctly (there were a few conflicts), I would appreciate it.  Thanks again!!!
