My default MOH seems to be working fine, but when I upload new audio sources and set them on either a device or one of its lines, I get dead air. Has anyone else run into this?

MAke sure you upload the files to each MOH server or each CCM Server in which MOH server is enabled

I have been using the .wav files from the CUCM 6.0 MOH disc.

Are you using multicast for those resources...and which codec you are using, r u getting dead air or tone on hold?

Any device that may be blocking the audio?

If u can upload the trace i will be more than glad to help you

We are using G.711. No tone on hold, only dead air. Audio is not being blocked because the sample MOH plays fine.

I have similar problem. Can someone clarify how to upload MoH file on each separate server?

I have three CUCM MOH servers in the cluster. I upload the file via CUCM Administraion GUI->Media Resources->MOH audio file management. My understanding is that the file should be replicated to all configured MOH servers in the cluster.

But it seems it isn't. I found this log restarting IP VOice Media Streaming Application service:
12/16/2009 12:19:43.503 VoiceStrm|   CIpVMSMgr::GetAFile *ERROR* Error getting MOH source file, errno=2|

I can see server cannot open audio file when it tries to play audio:

12/16/2009 11:37:01.310 VoiceStrm|   CIpPlayWav::StartPlaying (78,2003,0) *ERROR* Error openning WAV file (/usr/local/cm/moh/TestMoH.g729.wav)|
