[cisco-voip] Problem between CUCM 7 and Avaya Media Gateway

[Rynard Coetzee]

Hi
I have a H323 gateway on the CUCM server pointing to the remote Avaya Media Gateway ,I have the region on the CUCM setup to use G729 and I have MTP required ticked on the Gateway configuration. When I dial the phone on the Avaya side ,I hear silence for about 10seconds and then I get a fastbusy. Does anyone have any idea what else I can look at ?
Regards
