[cisco-voip] Tips for Multicast Music-on-Hold MOH from router flash for remote site

[Jason Aarons (US)]

Credit go to Jane Ryer for the inital version/info, here is expanded info;

Customer didn't want music on hold to cross the WAN for a remote spoke site. They wanted music to multicast from the router flash card out a local PRI for the site.

1. ip multicast routing and ip pim dense-mode in router (does it need to go on int serial0/0/0:23 where the PRI is? It does need to go on the interface that has the 7900 phones)
2. ccm-manager music-on-hold | moh music-on-hold.au | multicast moh
239.1.1.3 port 16384 <interface> configured in router (you can use any private multicast address but has to match CallManager)(adding the interface fixed my MoH not working)
3. Enable Multicast Audio Sources on this CallManager MOH Server
4. CallManager MoH Server Base Multicast IP Address = 239.1.1.3
5. CallManager MoH Server Base Multicast Port Number = 16384
6. CallManager MoH Server Increment Multicast on = IP Address
7. CallManager MoH ServerMax Hops = 5 (or less if you want to keep it off WAN)
8. MOH Audio Source:  SampleAudioSource (1) = Allow Multicasting
9. In Media Resource Group =  Use Multicast for MOH Audio (requires at
least one multicast MOH resource)
10. Cisco IP Voice Media Streaming App = 711 mulaw and 729 Annex A
selected.
11. Media Resource Group List configured in Device Pool level with
appropriate MRG.
12.MOHMulticastResourceActive counter got incremented when put the call
On-Hold.
13. Verify you put the music-on-hold.au on the flash:

Smaple Running-config from IOS 15.0(1)XA3
ccm-manager music-on-hold
ccm-manager config server 10.10.55.133 (CallManager IP)
ccm-manager config
ccm-manager sccp local FastEthernet0/0

telephony-service
moh music-on-hold.au
multicast moh 239.1.1.11 port 16384 route 10.225.106.2

show ccm-manager music-on-hold
show ip mroute
show ip multicast interface
show ephone moh (only in SRST mode)
