MOH on Router Flash



Attached is the network diagram. Also attached is my LAB config for a spoke Site B.

We are running CUCM 8.6 on Site A. Site B run SRST CME.


I have 2 MOH audio source loaded on the publisher and only 1 is setup for multicast.

MOH Server, MRG and MRGL is setup and applied on both Device Pool, IP Phones and Site B gateway.


Site B has been loaded with MOH wav file in flash0 and is the same file configured in CUCM for multicast.

Site B phones when one is place on hold, I can still hear the Server configure MOH under Service Parameter and not the MOH loaded in Site B flash.


Here are the show commands on Site B when I place a call on hold with the Site B network. Also same result when I call over PSTN, I hear the Server configure MOH instead of SIte B flash MOH.

Hi,Is the Multicast box


Is the Multicast box checked on MoH source, MoH server and MRG?

What is the max hop setting on MOH server enabled for multicast? Try to set it to 1.
