Could you post your sho run on the router that you are sourcing the MOH from? If you are getting dead air, that means your CCM is setup correctly and the issue is pointing to the local MOH configuration. Do you have at least 1 ephone defined?
Another note, if you had it working with g711 and just changed the moh / multicast information to reflect g729 you may have to delete the entire call-manager fallback configuration and paste it back in with the g729 information. I have run into this in the past.

I have read and re-read the MOH section in the CallManager Fundamentals book, and in the CUCM 7.x SRND and I don't see where either went into detail about the different mcast addresses 239.1.1.1, .2, or .3. My question is, where can I look to read up on them and this issue? Amp Quoting Vik Malhi <vma...@ipexpert.com>: The two solutions work- either you place your MOH server in a g711-always DP and your should set the SRST router to use 239.1.1.1. OR...IF you did but the MOH server in a DP that uses g729 to site B (for whatever reason) then you should set the SRST router to use 239.1.1.3. The MOH file on the flash will be sent out using the same IP Address CCM is telling the phone/gateway to listen. The phone on hold is receiving RTP packets and the payload type will be g711u- however CCM ³thinks² that the MOH server back in HQ is active and the stream is g729. But I guess that¹s the whole idea of spoofing- CCM is not aware of what is going on. The codec CCM ³thinks² is being used and the actual codec are different- but that will not affect the end result. Also- while we are on the topic of sourcing music from the flash- you all should be putting in the command: no mgcp timer receive-rtcp (in the case of an MGCP gateway).... -- Vik Malhi CCIE #13890, CCSI #31584 Senior Technical Instructor - IPexpert, Inc.
