Hi.
We have CUCM 11.5 => SIP Trunk => 4321 Voice Gateway => BRI => PSTN
When I make a call from the cisco sip phone to the PSTN, MoH works to the PSTN and also I am able to transfer the call from a cisco phone to another cisco phone successfully.
When I make a call from the PSTN to a cisco sip phone and I press the hold button at the cisco phone the caller from the PSTN hears a double beep and not the MoH. Additionally when I transfer the call to another cisco phone I hear the double beep till transfer is pressed twice and the receiver picks up the call and then nothing happens, I hear dead air.
Can someone help me?

Two different issues here. One with MOH and then with audio. Is it one-way audio or is it no audio at all ? Who is the MOH source ? IOS or CUCM ? Multicast or Unicast ?

It is no audio at all.
MoH is the CUCM Sub and then Pub and it is Unicast.
