[cisco-voip] MoH Multicast

[Voll, Scott]

I have CM setup to use Multicast for MoH.  It works on the local LAN but
over my WAN all I get is silence.

When I do a Sh ccm music I see the the multicast address and RTP port.
I see the codec is G729 but I have no incoming interface and packets are
not going in or out.  Based on that, I think my configs are good.

IP Mutlicast routing

Ip pim sparse-dense-mode on each interface

ip pim rp-address x.x.x.x to the main router.

What else am I missing?  I'm not sure it's a codec / bandwidth issue on
CM.  Can someone direct me?

Thanks

Scott
