CCM 4.1(3) MOH sound quality distortion

Unanswered Question

I have problem with a cluster with four CCM servers. Every one of them is running CCM service but the one dedicated for MOH has only a few end devices and performance looks OK. We are experiencing bad sound quality from the MOH server.

Is there a reliable way to investigate and troubleshoot is the problem relayed to the server performance or something else? May I capture RTP streams from the MOH server and look at the achieved delays and jitters.

Please recommend me a technics to troubleshoot this if you have touched similar problems.

Thanks in advance.

The problem isn't in the file 100% because sometimes the quality is good, sometimes bad. There is another reason. I can send you the files but they are the default files that comes with CCM. A kind of monitoring can help me.

you can use span session on a switch port and connect a PC with ethereal to capture the RTP stream and look into jitter and delay.
