I posted on the website some instructions (not available yet in the tar-ball) about how to see the current media sessions on the web.

Thanks Adrian,
I tested now and it works great! No choppy audio on Xten. I still see the RTCP packet coming out of the Xten client, but it never gets back the "ICMP Unreachable". I don't know if the ATA186 supports it though. In any case the audio is crystal clear.
I also like your "sessions.py" program. It is quite useful.
Regards, Ricardo

Adrian,
I am sorry but it does not run on our RH7.3. I have python 2.2 but not the optik module. Could that be the problem? I could not find that module for our version of Linux. Not even a web page to download the source.

Interesting, did you try my media proxy before saying this?

I can confirm this too. Just tried it in our lab with the exact same results as Klaus. (Instead of Budgetone I used ATA186).
X-Lite build 1084
- ATA186 Calls Xten.
- Xten hears choppy audio every 5 seconds or so.
- RTP Stream from ATA to Xten is perfect and conserves the same
SSRC 4. RTP Stream from Xten to ATA switches to a new SSRC every few seconds.
It is clear to me that there is a bug in Xten software. Before Xten switches to a new SSRC it attempts to send an RTP packet to the wrong RTP Port (it tries to the actual port +1). SER server sends back "ICMP Port Unreacheable (Obviously)" and Xten restarts RTP Stream on a new SSRC.
I did not see any problem with Maxims RTPProxy.

I can reproduce the choppy audio setup: budgetone-100 <----> ser+rtpproxy(version from today) on redhat 9 (or 8, not sure) <------>x-lite build 1088 on win xp
the choppy sound occours every 5 seconds, in both directions. RTP-analysis: RTP stream from budgetone to x-lite (via rtpproxy) is fine (no jitter, no loss) RTP stream from x-lite to budgetone (via rtpproxy): very strange: x-lite switches to a new SSRC (and seq-nr. start at 0 again) every 5 seconds.
so, in my opinion: rtpproxy works fine, x-lite is guilty. but why does this happen only if the rtp proxy is involved? ...further investigations are planned...

Well, we can generate the traces locally, but I haven't encounter the problem you describe so it makes no sense.
You wrote you are able to reproduce the problem, in that case I would like to ask you to generate the traces that show the problem so we could analyze and fix it.
Also please tell us on what OS does this happen ? (I mean the OS the proxy is running on).
Another question, what is the license of your RTP proxy ? I didn't find any licensing info in the sources. Will the sources be available ?
