I am trying to implement srst MOH from flash for my customer. I have configured evrything as I have done in the past but this time no joy.
I have done the ff:
1. configured loopback interface
2. enable ip pim sparse-dense mode on loopback interface, gig0/0 and gig 0/1 interface
3. enable Multicast MOH on audio source and MRGL
4. Configured G711 for multicast MOH
5. configured Multicast MOH on srst router and loaded MOH to flash
attached is the relevant config
2. When I do a show ccm-manager music-on-hold
I get this
SWIPCR01#show ccm-manager mus
SWIPCR01#show ccm-manager music-on-hold
Current active multicast sessions : 0
show call active voice | include RemoteMedia
I get this...
SWIPCR01#show call active voice | include RemoteMedia
A show ephone summary displays
SWIPCR01#show ephone summa
SWIPCR01#show ephone summary

Moh multicast on 220.127.116.11 port 16384 via 172.26.208.1
A debug ephone moh shows this
Apr 24 10:33:09.641: MoH route If Loopback1 46 172.26.208.1 via 172.26.208.1

Apr 24 10:33:14.757: MoH route If GigabitEthernet0/0 ETHERNET 172.26.208.117 via ARP
from the above, it is obvious that Multicast is not working. Why I do not know...
I looked at CCM trace and I can see the follwoing: n(CCM trace attached)
From the trace , I can see audio source id of 1 been selected which is correct...
04/24/2009 10:28:17.246 CCM|MohDControl - handleMohSuccess - Call Id = 43114191 AudioSourceID = 1 MuticastFlag =
However, I can see CCM telling IP phones to listen to multicast on Ip=16843247, port 16384.
The port is correct, but im not sure of the IP..it should be 18.104.22.168
04/24/2009 10:28:17.246 CCM|MohDControl - handleMohSuccess - Sent out Allocate MOH Response CallId=43114191, TransferMode=9, Ip=16843247, Port=16384, CapCount=1, AudioSourceID = 1 MuticastFlag =
Please guys what do you think.
In this setup, my router does not have an interface in the phone subnet. I have enabled ip igmp snooping on the switches with no luck. I even enabled ip multicast routing on the router with no luck.
CCM is located across the WAN over an MPLS circuit hence, we cant configure multicast routing.
What can I do..
