I have successfully configured Multicast MoH for a remote branch's IP phone. A router is used to stream the audio file to the remote branch. However, on that router, we can only specify 1 multicast group address with udp ports.
My question is what happen if the CCM1 at the central sites fail and the branch router register with another CCM2 in the same cluster, but this time the multicast address specified in this CCM2 server is different from CCM1 (i tried to put both address to be the same, but has an error). If the address is different, then the remote branch ip phone will listen to the different multicast group address and multicast MoH will fail...
Can anyone advise how can i achieve redundancy in multicast MoH scenario ?
But the remote gateway router is only streaming 1 multicast address, say 220.127.116.11 port 16384. So when CCM1 fail, the phone will listen to 18.104.22.168, but the router is streaming 22.214.171.124., so it will not work.
Thanks for your reply. We have dual router at the remote sites. Your suggestion will take care of CCM failure. But if one of the gateway routers at remote branch fail, the phone will still try to join the multicast group of gateway 1 (since the CCM is still working) which is no longer available.
