I have a simple setup with one core 3560 switch with 2 vlans Data 192.168.100.x and Voice 192.168.200.x and CME 4.1 installed on a router 2801 with an IP address 172.16.0.1 connected to it. My phones are registering well and I am able to call. When I am trying to implement MOH it doesnt works here are the commands which I Have used
multicast moh 18.104.22.168 port 2000
your help will be appreciated
Do you have multicast enabled on your switch and the voice vlan since it is different network from CME?
Do you have the moh source in flash?

I havent enabled the Muticast on my switch and the voice vlan. How do I do that ? Do I have to do it on the router as well.. Yes I have the files in flash..
Can you find the below?. I hope to check if the audio file on the flash.
also find the following URL:-
please rate all useful infomation
Yes, if the router is on different vlan than the phones that need to get the multicast moh stream you require multicast routing between the vlans.
try to do the following on the router:
ip pim dense-mode
no multicast moh 22.214.171.124 port 16384
multicast moh 126.96.36.199 port 16384 route 172.16.0.1 172.16.0.2 192.168.200.1
On the switch you'll probably have to insert the ip pim dense-mode commands under the Vlan200 and the Gi0/2 interface as well.
Thanks Greg . Presently I have IP base image on the switch, in order to run the pim command I will have to upgrade it to spservice IOS and do what you mentioned above and let you know.
