I asked a similar question, not observing this one. I would suggest some monitoring tools that will give you an indication of jitter, loss, delay, etc. There are many things that will do this, although they all have different good/bd qualities. I believe wireshark will, there are other tools dedicated to RTP traffic analysis. http://www.voip-info.org/wiki/index.php?page=How+to+debug+and+troubleshoot+VoIP has some links to tools that claim to do this. -- Trixter http://www.0xdecafbad.com Bret McDanel Belfast +44 28 9099 6461 US +1 516 687 5200 http://www.trxtel.com the phone company that pays you!
