I think you are running into the same PL "mutlicast not working over VPN". It is been quite awhile since I have used the PL racks for voice, but remember they had a reccomended way for testing mutlicast. Just cant remember.

James - The command is not in my config. I attached it for reference. When I run a "debug ephone moh" I can see the MoH routes being used. However, if I run a "show ccm-manager music-on-hold" while the PSTN caller is on hold, I do not see the session count increment from 0 to 1. This seems off.

If so, make sure the no mgcp timer receive-rtcp is NOT in your config. If it is, remove (don't forget no mgcp/mgcp ;-) ). Place a call in from pstn and place on hold. Your call should disconnect after the given time.

James, I see what you're saying here. Could you recommend a good test scenario to see this 30 sec disconnect? Right now, my phones are looking at 239.1.1.1 for their MOH, the CUCM Sub is setup to send MMOH out over that IP, but I am blocking multicast from traversing the WAN. I also have SRST setup with the proper MOH commands. I thought that was enough to test this scenario. Is there something I am missing?

The command is needed when sourcing MOH from flash on am mgcp gateway. As soon as call is placed on hold, mgcp traffic stops traversing the wan and the call will drop at 30 seconds. When multicasting across the WAN as you are doing, no issues. Was able to reproduce this in the lab during my studies.

The following is an excerpt from Mark Snow's V3 VoD released late last year. • If on an MGCP gateway: “no mgcp timer receive-rtcp” – If you have an MGCP gateway at a remote site and the requirement is to have a no-WAN MoH solution, you must enter this command. o You will be sourcing the MoH locally on a SCCP “server” (SRST gateway) and no MGCP traffic will be traversing the WAN. o Otherwise, you will be on hold for exactly 30 seconds. When testing, stay on hold for at least 1 minute. I just went through Vol 1 Lab 7 Question 7.2, where you setup MMOH over the WAN to BR1. I did some testing and verified that this command was not needed to maintain a connection between the PSTN phone and BR1 Phone 2.
