We do have UCCE 8.5 with CVP 8.5 in a h.323 comprehensive model deployement.
We are planning to change the signalling method from H.323 to SIP.
We installed two SIP PROXY servers (2x 2951 with NME CUSP), but we're using only one now. After configurin the CUSP and the VGs, calls are failing to get to CVP. It seems that there is an issue between the VG and the CUSP.
We activated CCSIP and ISDN Q931 traces on the Gateway (@IP 172.20.10.240).
CUSP @IP is 172.20.10.25
It seems that the GW can't negociate the codec, i think. But the codec is explicitly configured under the VOIP Dial-peer.
