Description (partial)

Symptom:
This is an enhancement request. The default value of CUCM MOH multicast packets is 2. This can cause issues with routed networks that have a diameter that is greater than 1 router. If the TTL expires in transit the packets are dropped by routers and MOH will not work. This feature enhancement was filed to get the default TTL increased to 64.

Conditions:
CUCM 9.x with MOH server configured for Multicast.
