[cisco-voip] MoH with SRST remote sites

[Johnny Crothers]

Ahh.. I didn't click with the increment ip/port number thing.

Thanks for clearing that up Ryan!

The point of the new Region is so that all of your devices will be  
configured to use g.711 to the MOH servers.   This is done so that  
you can use the g711 MOH source streamed from the flash of the  
router.   The whole point of this config is to trick the phones.   
They don't care where the multicast MOH comes from, as long as it  
comes on the IP address and port that CM tells the phone to receive.   
In order for CM to allocate g.711 MOH to the remote site phones the  
region settings between the phone and the MOH servers needs to be set  
to g.711.   If it is not then the CM will tell the phone to listen  
for the MOH on the g.729 port which is not what the router is sending  
to.

Hi everyone,


Just trying to clarify how I should be configuring MoH with SRST sites.


I'm running G711 at CCM site, G729 over the WAN and G711 at the  
remote sites using MGCP gateways with SRST.


I have configured the SRST routers with a MOH filename and a  
Multicast address that is the same as the multicast address used on  
the CCM MoH server


I'm reading the white paper and I see that it states to add another  
Region for the MoH server to ensure that G711 is used at the SRST  
sites. Is this how it is to be read?


I thought the phone would just join the multicast stream provided by  
the SRST router.


Am I wrong in thinking that I do not need to create a separate region  
for the MoH source (Specifying all other regions as G711)?


Thanks in advance for your help!


Johnny
