First. Can you route multicast in your network?
Second if you can. Check TTL value in MOH settings. TTL 2 will allow to pass 2 hops for multicast packets.

Muiticast routing is not enabled on the network. I'll configure multicast Thanks a lot.

Make sure your router configurations has these commands in it and that the ip address in your call-manager-fallback section matches what is configured for your MOH ip address in CUCM and make sure you have a loopback address configred for MOH as well.

multicast moh 239.1.1.1 port 16384 route 10.138.207.65 10.10.240.107
Note in my example that the multicast moh ip is what should match your cucm ip, the port also has to match and the router would be your voice sub-interface via your loopback interface. Also make sure the moh file is on the flash card of the rotuer and that the name of the file is exactly the same in your call-manager-fallback section.
