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?

Mark is correct here. 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.

Lab Results?
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.
Has anyone else seen this?
