we have one installation with Cisco 4331 router configured as H323 gateway at CUCM.
The problem is that callers from outside don`t hear MoH when they are hold or transfered. They hear nothing while hold or tranfser.
MoH internal is working.
The configuration is mostly the same as at other installation with Cisoc 29xx routers as H323 configured where MoH to external is working fine.
At the Cisco 4331 gateway at CUCM the MRGL is configured to use CUCM as MoH source.
Actually in the gateway at CUCM "Media Termination Point Required" is disabled as when I enable it the external call will be immediately disconnected when I press hold or transfer.
Is there something special to configure to get MoH over the Cisco 4331 router?
