I might have actually observed sound quality distorsions with Windows Messenger too when used along with rtpproxy. I don't know whose guilt the distorsions are (could it be somehow related to lack of RTCP?) and quite likely it is other issue than Klaus discovered (Klaus, thank you!). Excuse my vagueness -- I would love to verify it, but my ISP screws me now and I'm forcibly off-line.
I will let you know more as soon as I am online.

ps -- What is the license for the new media proxy?

The problem is that every few seconds there is a gap of half second in the audio stream (quality-wise the conversation is unacceptable) when using Xten softphone X-lite or X-PRO on either Win or Mac via RTPProxy. I can consistently reproduce this problem 100% on various systems and so do all my customers.
For the sceptics, there is a movie with the problem presented (Quicktime is required to play the stream): http://download.dns-hosting.info/SERMediaProxy/ XtenProblemWithRTPProxy.mov
and an audio extract: http://download.dns-hosting.info/SERMediaProxy/ XtenProblemWithRTPProxy.wav
This is the problem solved in our media proxy.

I am also wondering what is the problem with xten and rtp proxy, because I didn't have any problems.

Sorry for my sloppy English, actually I was asking you to explain the cause of the problem. If you claim that something was "solved" in your version you should probably know how behaviour of your version differs from the behaviour of the original one.

Hello, we have released an alternative RTPProxy that works with SER nathelper module. Is a completely new program written in Python and should be able to run without recompilation on any system where Python is supported. We have tested Linux Debian and Solaris 8. There are little differences against PortaOne's rtpproxy, mainly the problem with Xten choppy audio was solved.
Interesting. I wonder what was the problem with Xten that you solved?
