Description (partial)

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.

CUCM 9.x with MOH server configured for Multicast.
