Hi,

Coud you tell me who is not able to hear MoH? Is it the internal phones or the PSTN? could you also tell me the call flow when the MoH is not working.

Hi,

When an internal IP Phone place a call that receive from external on hold, the PSTN caller don't hear the MOH, but if the it's the internal IP Phone that calls the external phone and place it on hold, the external called can hear the MOH.

call flow when the MOH is not hearing : PSTN --> GW --> CUCM 4.X -->internal IP Phone
