CUCM 8.x with remote sites and 2800 series routers at each site. Phones register centrally. Is there anyway to get MOH from an audio source that is local to the remote site instead of coming across the WAN? Bandwidth is at a premium.
Thanks, Replies rated.
Here is the article I followed to get it working. Hope this helps.
You do not need to enable multicast for this to work as long as the phones at the remote site are on the same VLAN as the gateway, essentially what you are doing is faking the phones to think they are connecting to multicast IP address of CUCM server where in fact the multicast traffic is local to the remote site. No multicast routing needs to be enabled if all phones are in the same multicast domain (vlan) as the GW.
