i've got a big plroblem, i haved configured multicast MoH with CCM/SrSt on remote site. On remote site when i call from PSTN I can hear MoH and when they put me in "waiting",on router SRST i see that Multicast MoH is working good . But the problem is when the customer call on-site, they can't hear MoH. what can be the problem?
Matteo, firstly I want clarify that I understand your topolgy, essentially you have a hub and spoke WAN with SRST at the remote branches which also provide MMoH?
If my understanding is correct, then the fact the 'show ccm-manager music' indicates that the CallManager is allocating the MMoH request, and therefore it is correctly configured for MMoH.
Ensure that your MMoH server/audio-source is associated with a device-pool where the region is configured to stream G711 to all other regions/remote branches. MMoH on IOS only support G711.
Two aspects which you initially try, firstly verify with 'show ephone summary' that the audio-file does not show invalid or in error.
If the file does show invalid then try removing and re-applying call-manager-fallback', this should correct the problem.
Secondly, add the gig0/0 interface to the mmoh command under call-manager-fallback:-
'multicast moh 18.104.22.168 port 16384 route 10.254.254.1 10.9.202.3'
Hope this helps.
