hello
i've configured an IP PHONE 7960G to receive incoming calls from PSTN.
the problem is when i put a call in waiting state, the PSTN caller does not receive the MOH, while a local IP phone can listen to the MOH.
any idea?

Does the gateway that the incoming call comes in, have a MRGL assigned to it, either through Device Pool or at the gateway device level?
Also check if that MRGL has a MRG which contains the MOH server.
As a test, you can put the gateway in the same MRGL as the local phone device that hears MOH. Now does the PSTN caller hears MOH?
Also, check if g729 MOH stream is configured for the gateway. If so, verify if g729 is selected in the IPVMS service parameter.

7960G___CCM____1751V_______PSTN

if you're doing multicast music on hold with your network, you're missing several things.
1. you'll need a 'ccm-manager music-on-hold' statement on the router
2. you'll need to enable multicast:
ip multicast-routing
3. you'll need the fast ethernet interface to participate in multicast
int fast 0/0
ip pim sparse-dense-mode
TAC also seems to think that you need to be using a loopback interface for music on hold to work, not sure on that one.
Also, make sure you're on 12.3.4T3 or higher because of bug CSCed28531
