cjrchoi11
Level 1
Level 1

Symptom

-------

I'm testing the MoH between IP Phones in the LAB (No PSTN available)

1. in normal mode, remote IP phone can get MoH from local SRST/CME router successfully

2. in SRST/CME mode, I hear ToH when press Hold button in remote IP Phone

CCM6.1.2 configuration

----------------------

-g729 between HQ and remote office

-create a region to assign g711 between MoH server and remote office

-MoH server=enable multicast(239.1.1.1, port 16384, increment=port numner, max hops=1)

SRST/CME configuration

put on the source address interface

h323 voip interface

h323 voip bind srr add 10.0.23.1

if didnt work make the wource interface as a loopback interface make it the source for voip and for sccp as well and add it to the moh multicast route

also try to remove the moh config and re put it again

good luck
