No MOH to the gateway

[snootalope]

MOH worked just fine for external callers before we upgraded to 6.1 from 4.1.

CUCM 6.1
2811 gateway

MOH is working just fine internally, dn to dn. I've configured the DP to use the MRGL, this is the same DP the gateway uses, and even specified the MGRL in the gateway's config.

I've used the "ccm-manager music-on-hold bind FastEthernet0/0" on the gateway to bind it to the Ethernet port that connects to the CUCM's.

I've made sure the IPVMS has all codecs selected.

Using the "sho ccm music" on the gateway while i've got an external call connected to an internal phone, and on hold, I can see it's connected to the multicasing MOH server address.

Current active multicast sessions : 1
Multicast RTPport Packets Call Codec address
===================================================================
239.1.1.1 16384 0/0 206774 g711ulaw Fa0/0

I've tried removing the voice-class codec from the dial peer so the calls use g729 instead.

The external caller here's nothing. and voice packets on the "show ccm music" never grow, they always stay zero. This makes me think it's a codec issue, but I'm out of ideas.

Are you playing the MOH file locally from the router or are you streaming it from the ccm server?
Did you upgrade/replace any of the routers as well during the 6.x upgrade?

MOH is playing on my publisher server. No upgrades to the routers or gateways after the software upgrade. Hardware devices were replaced while using ccm 4.1
