[cisco-voip] UCCX with H.323 gateway

[Aman Chugh]

Hi Peter,
Thanks for helping out, I did go through the traces, In fact I captured CCM
and CTI for this, I see CCM sending the call to cti port in jtapi port
group. Let me send you the traces and I do have MRGL assigned to gateway and
cti port with hardware transcoder in it.

Once again thanks for help.

In the traces look for dd=1588 as that's my cti rp.
