MoH on Cisco CME.


Hi to all,

I have a router Cisco 2801 (is a lab scenary) configured as call control. I have configured a CME 8.0. All is working properly but when I put a call waiting with an analogue phone connected to an ATA, MoH works fine but when I put the call waiting with a 7911 IP phone, the MoH isn't ear in the other peer.

Any Idea?? Seems something about DSP but, why works when I hold the call with the ATA?? 

The two types of phones are configured by the same mode. Tell me if you need something about.

Thanks for your help.

You have to use multicast MOH

You have to use multicast MOH for CME IP Phones.  Can you attach your full running config?
