I confiugure my MOH sources to be sent out via Multicast everything seems to working. I can see the mulitcast group being registered in the 6513 with and 8 port T1 blade. And I can see the devices join IGMP group.
The problem is that all phones on the network receive the MOH. But calls coming in from the gateway dont.
When I put two phones on the network on hold I see the VLAN show up in the IGMP group, When I put the phone that is connected through the PSTN on hold nothing showse up in the IGMP group?
