I have CUCM-BE with Unity connection (Standard) ver.188.8.131.5200-26.
Main number is answered by Unity and transferred to a hunt group. When the call is transferred you hear three beeps. I have configured a MOH on the Device Pool where the Voicemail port are. I would like to get rid of the beeps and only hear the MOH from the call manager.
I think you need to make sure that the Incoming Gateway has access to the MOH

Gateway is MGCP gateway and should have the right config.
no ccm-manager fax protocol cisco
ccm-manager config server 10.45.0.10
mgcp call-agent CUCM 2427 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode cisco
mgcp rtp unreachable timeout 1000 action notify
mgcp modem passthrough voip mode nse
mgcp package-capability rtp-package
mgcp package-capability sst-package
mgcp package-capability pre-package
no mgcp package-capability res-package
no mgcp timer receive-rtcp
mgcp sdp simple
mgcp fax t38 inhibit
mgcp profile default
What about the gateway config in CUCM
You need to make sure that it has access to the MOH server via the MRGL in the device pool.
Just to add one other thing to the great ideas from Alex (+5"A"!)
I believe the MOH relationship for the CUC ports is actually built via the Common Device Configuration
settings that are applied to the individual CUC Voicemail ports (via CUCM). Have a look at what the
ports are using in CUCM and either adjust the MOH references or build a new
Common Device Configuration profile that uses the proper MOH and reconfig the ports
There's a relatively new bug ID that has been causing this type of problems on PSTN calls with H323 GW and IOS 15
Is the problem only MOH when doing the transfer?
What happens if you call from an internal IP Phone to the same Translation pattern going to Unity, leaving the Gw out of the picture?
Do you have problems with MOH for any other PSTN calls?
It is actually very simple and very strange. I have two translation patterns that translate the main number to a hunt pilot that uses a set if voicemail ports to call a call handler in Unity. Both number is doing the same set of port, same set of ccs and pt, same MRGL. One call handler delives a wellcome message and sends the call back to a switch board system the other is a IVR asking for caller input press 1, press 2 etc.
The forwarder to switchboard forward and when testing i can get it to play MOH
The IVR plays three beeps on transfer nevermind what i do. I have even change it to forward to the switch board system i still plays. I makes no difference.
I get the excact same issue whether i dial internally or externally through the gateway. So the gateway is not the issue.
The issue is in UNITY and the way it uses MOH on the cucm.
