MoH only the sample through the gateway

Unanswered Question
Jun 2nd, 2010


My MoH works fine internal with different audio sources, but through the MGCP Gateway only the sample audio file works. When I use the other I hear nothing.

Here is my setup:

1 Pup

1 Sub

CUCM 7.1.3

MGCP Gateway

no multicast is activated at all adio files

I does not depend on the MRGL. From IP Phone to IP Phone it works fine.

I hope you can help me.


I have this problem too.

MRGL DOES affect whether you get MOH or not. The device pool needs to have a MRGL with a valid MOH server.

Have you loaded the MOH files to ALL MOH servers?

You can try enabling more MOH codecs under the IPVMS service parameters

The MRGL of the GW will allocate the MOH server. From your description looks like the MOH server does not have the custom MOH audio sources uploaded to it, and thefore is giving you dead air on any audio source beside the sample.

Check what MOH server the call is connected to with show call active voice compact, and then make sure all the MOH custom files are uploaded to the server.
