MOH Multicast vs Unicast

Is it possible design a blend Multicast environment where the HQ will use
primarily unicast from the Software MOH and remote sites use Multicast from
local route. I was thinking this was possible by enabling just 1 multicast
server (to be used as the spoofed Local Router MOH multicast address) and
all other servers are unicast. Limit the hop count to 2 and setup the local
routers according (with the multicast config and single file for MOH).


Best Regards,

Mike,
This can be accomplished, even with a single MOH server. You simply set one MRG up for multicast and the other up for unicast. The main thing to remember is to keep your audio source the same. Otherwise, placing calls on hold between locations will not get music but instead tone on hold - the ip or port (depends on how you set up your multicast) changes with differing sources.

Cheers,
Bob

Yes, the MOH server/source combo determines if unicast or multicast is used, and the server part comes from the device getting put on hold. Enable all of your audio sources for multicast and they can do both. Then it's just a matter of setting up the MRGLs so that HQ phones get a unicast MOH server and remote ones get a multicast server.

Re: MOH Multicast vs Unicast [In reply to]

What if it's a single server deployment? Can you configure some phones for multicast and others for unicast moh via MRGL? I'm not clear if a multicast stream fails to get to phone (due to MPLS network), will phone switch request to unicast somehow?

Re: MOH Multicast vs Unicast [In reply to]

For a single server you put the MOH server in two MRGs, one with multicast enabled, one without. Those MRGs go into separate MRGLs that will be used by the phones at HQ (unicast) or remote site (multicast).
There is no mechanism to fail back to an alternate MOH server. Once CUCM has allocated a server and told the phone then you either get MOH or nothing.
