I have a UCM 6.1 cluster with several h323 gateways. I am having a problem with the Hold/Transfer features on one gateway. The gateway is a 2851 running 12.4(24)T with one NI2 PRI. The gateway and phones are on the same local VLAN, and the CM server is across a router on a different network.
Station-Station calls work fine. When a call is placed on hold, the MOH is delivered and the call can be retreived.
Calls coming in through the gateway are able to complete. Unity is able to deliver prompts and record. However, placing the call on hold causes it to be immediately dropped. A Q931 debug on the gateway reports a "Temporary Failure", but otherwise I get no errors reported.
I'll be glad to post any other traces that would help...I was not sure what router debugs would be helpful, or which log files would be most relevant.
Any direction at all would be great.
