H323 Gateway Intermittent MOH Silence

We are using a 3925 router - c3900-universalk9-mz.SPA.150-1.M4.bin - as an H323 gateway with 2 PRI's. We have a PUB and a SUB running -

System version: 8.5.1.11900-21 When we place people on hold we get MOH very intermittently. Out of 10 calls 8 might get MOH and 2 get silence. I have checked codecs (all calls G711), I have restarted IPMediaStreaming. The weird thing is that some calls work and some do not. We cannot isolate any factors to be the same or possible causes. I uploaded the voice portion of the router to see if it helps. Thanks for any help.

Thanks,

Donnie

Hi

Are you using. Multicast MOH or unicast MOH. Also Are you using MOH stream from Router's flash or you are using MOH stream coming on CUCM.

Hi,

I have the same problem.

Did you solve it?

Yes. I looked through the bug toolkit and found SEVERAL of the IOS revisions had issues with H323. I changed the gateway to MGCP and the issue has gone away.

Thanks,

MGCP is not an option for me, but I think I managed to find a workaround, testing it right now:

HEllo,

I had the same issue. Check the BUG ID. My IOS version is 15.0(1)M4 on a Cisco 2911. The affected IOS version described on the Bug ID.

I've made the Option2 Workaround and the issue got solved.

Thanks for the info.
