If CCM is configured with MoH multicast with a multicast ip address but the network does not configured for any multicast routing ( PIM and IGMP ). In this case how does MoH work ? first of all Will MoH work ? if it would work, then the stream flows as unicast or broadcast ?

hi sir

obviously it wont work....

If network is not ready for multicast use server as moh unicast, cucm is not network aware, will just stream multicast packets.

One more clarification, If i place the CCM and all the phone in one network i dont need to configure any L3 multicast routing (eg PIM )and if i do not configure any IGMP snooping in the switches how will be the rtp streaming. Will the switch forward the MoH stream out of all switch port ?

Multicast for switches will be treated like broadcast.
