[cisco-voip] Unicast MoH nto working out to PSTN

[Buchanan, James]

I imagine multicast is enabled somewhere for MOH-you've checked your audio source, your moh server, and your media resource groups I assume to ensure multicast is turned off?

No joy guys with the suggestions but I have made progress - it gets stranger!

I have configured my MoH as unicast, all my phones and gateways have the same MRGL and my phones are getting MoH internally.  There is no multicast MoH set up.  As a last resort, I configured "ccm-manager music-on-hold bind......." even though I know it's not multicast - and what do you know - it works?

When I do a "show voip rtp connections" when a call is on hold, I see the source as the multicast address.  What's going on??

Anyone have any idea?

Did you say the codec between your remote sites and your MOH server is G729? If so, try putting all your MOH in a dedicated device pool,  region, etc., and set the relationship to G711.

On the CEF thing, the other workaround for that, suggested on this forum, was to enable Duplex Streaming in the CallManager service parameters. That worked like a champ, and did not have the effect of pegging the CPU on the router.

Thanks,

Thanks for the reply Chris, no joy I'm afraid.  Disabled CEF and same results.

Hi Guys,

I'm having an odd issue.  I'm unable to get Unicast MoH working for PSTN calls.  I've got my MoH server in a device pool to control MoH at g729 between my different sites.  If I configure MMoH and configure the gateway to use MTP it seems to work but this has a knock on effect for transferring to remote sites over g729.

Unicast MoH works fine internally.  I have the MoH media resources in an MRGL that's assigned to the phones and H323 gateway.  When I put a PSTN call on hold, I get silence (not ToH).  If I do a "show call active voice" I can see the packet count increase which would suggest to me that the gateway is getting the stream but not passing it on.  The VG is a 2951 with IOS 15.0(1)M4

Is there anything strange with 2900 or IOS 15??  I've used the same configuration for other sites but they've had 2800 with IOS 12X.

I'm kind of going around in circles at this stage so any pointers would be appreciated,
Thanks,
Neil
