Hi,
Branch Router is able Multicast MOH with PSTN phones but not working between IP Phones. I am enclosing the config below which I have at the brach location.
ip multicast-routing
int vlan 300
description voice vlan
ip pim dense-mode
call-manager fallback-mgcp
ccm-manager musin-on-hold
call-manager-fallback
ip source-address 192.168.10.1 port 2000
max-ephone 20
max-dn 40 dual-line
moh music-on-hold.au
multicast moh 239.1.1.1 port 16384 Loopbak IP and then VLAN IP

Hi,
This is how I have gotten Multicast MOh to work
Router
1. Configure ip pim sparse-dense-mode on all interfaces that connects to the switch including loopback interface
2. configure multicast routing to all interfaces that will route multicast traffic.
3. makesure the interface that connects to remote WAN has ip pim sparse-dense-mode configured.
Switch
1.Configure ip multicast-routing distributed on all switches (where phones are connected or swicthes in this path)
2. configure ip pim sparse-dense-mode on all interfaces that connect to router to
finally to test, when IP phones are on hold, use ? on the phone see if they are receiving packets

HI,
I have the different scenariow. Where as I have CUCM in HQ and two Branches and it centralized deployement, all my IP Phones are registered to CUCM. I want my branch routers to do the MOH from the Branch Router Flash but it is only giving me the moh for the PSTN caller. When an IP Phones calls it is silent. No music is there. Which definately means that it is not taking from CUCM but also not from the router flash.

First of all check that all phones are using the same network and user hold audio.Then check what ip address that it is configured for.
For example if the Mulitcast MOH in callmanager is set for 239.1.1.1 is that the same as the Multicast MOH ip address on the branch gateway?
