SRST MOH FROM FLASH

Hi,

I need to setup Multicast MOH to stream from branch router flash. I have read the doc, but I am not clear on if I need to enable igmp snooping on the switches and IP multicast routing on the router.

Can any one also post a working config.

Re: SRST MOH FROM FLASH

Hi

Of course you need to enable Multicast MoH on Communications Manager as well and assign it to the Device Pool of the phones.

If your SRST Router has an interface in the phone Subnet, then you won't need IGMP Snooping and Multicast Routing.

Here is a sample config if you use the music-on-hold.au file on the router flash (the loopback is needed if you want to stream to the POTS Interfaces):

interface Loopback1

description ** LOOPBACK FOR MOH **

ip address 192.168.255.1 255.255.255.255

!

interface FastEthernet0/0

description ** PHONE SUBNET **

ip address 192.168.1.1 255.255.255.0

!

ccm-manager music-on-hold

!

call-manager-fallback

moh music-on-hold.au

multicast moh 239.1.1.1 port 16384 route 192.168.1.1 192.168.255.1

Stephan, Thanks. What happens if my srst gateway does not have an interfce in the phone subnet?

Re: SRST MOH FROM FLASH

Hi

If it's not in the phone subnet then you'll need to configure multicast routing. You could configure static multcast routing.

But I'm not sure what the TTL of the MoH multicast packets from the gateway is. You'll have to check.
