How to verify the Multicast MOH from branch voice gateway?

[ciscoroyzhang]

Hi all,   have configured the Multicast MOH on branch office voice gateway, the "show ephone moh" indecates that the moh file has been cached. I also can hear the music. but how can I verify that this music is coming from local router not from the CUCM moh server?  thanks in advance...

off the local router do:

show ccm-manager music-on-hold

Should show something like this:

#show ccm-manager music-on-hold

Current active multicast sessions : 1

Multicast       RTP port   Packets       Call   Codec    Incoming

Address         number     in/out        id              Interface
