We are trying to setup a Cisco MCU 5310 for voice participants, calls are routed H.323 from an Avaya cs1000. We do not have a VCS gateway, and are setting this up using H.323. We are able to get inbound calls to connect, but when we have the MCU dial the participant the phone will ring, but the call setup fails as soon as the phone is answered. I have a TAC open, but having trouble getting any support from AVAYA, the Cisco engineer said the call is failing during the H.245 setup Excerpt from the TAC: "the Nortel side the h225 takes place and the connect message is sent but it does not contain any h245 connection information in the message, the cisco mcu sends the FIN closing down the h225 connection expecting to be able to open a h245 separate connection the Nortel then sends a tcp reset" The question would be does the Nortel expect to just use same network connection for h245 and can it be configured to send the connection information in the connect message which is what the cisco MCU requires? Anyone have this setup working, I'm not a Avaya person so I'm relying on the phone system vendor to configure that end, is there something missing from there setup. The MCU H.323 is fairly simple, the gatekeeper registration is working!
