I'd encourage you to get a good idea of what multicast traffic is on  
your network before throwing everything down the wan.

Another option is to use the SRST features of playing multicast MOH  
directly from a router's flash at the remote site.  This obviously  
won't allow you to have dynamic content in the multicast stream so it  
will probably not work for you.  I assume it will work with RTPMRx and  
RTPMTx.

Hi gang,

 

I’ve written an application that uses RTPMTx and RTPMRx, and after some  
debugging, it works well at my main site.  The problem arises when I  
try to use it to reach remote sites connected across the WAN.   
Multicasting here doesn’t get traffic there, and vice versa.  How do I  
configure this on my network?  My network infrastructure is all Cisco  
managed, multi-layer switches (3750s and 2940s).  I have Cisco 1721  
routers capping point-to-point T1s for connectivity to my remote  
sites. 

   

Can someone point me at the features I should be looking to implement?   
With a few pointers and a little coaching, I can probably do this  
myself.

   

Many thanks,

Jeremy
