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 ?

Adrian,
Do you have an Etheral trace trace of such a call (using G711)?
I guess ethereal traces can be generated with ethereal program and decoded locally on your servers if you want to isolate this.
I can decode it and produce an audio file for all to examine.
This way we

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
1. ATA186 Calls Xten. 2. Xten hears choppy audio every 5 seconds or so. 3. 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.

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.

From this description it seems to me that the problem is that Maxim's
RTP proxy doesn't relay RTCP (I think Adrian's does but I didn't try).
That might explain why Xten tries to send packets to media port + 1 and when it gets "port unreachable" it "does something wrong" :-).
It would be interesting to test this with kphone (kphone-xten directly without RTP proxy) which doesn't listen for RTCP traffic and thus the host will generate "port unreachable" too. Anyone willing to test this ? (I am travelling and couldn't do it).

Ok, I see, probably it tries to send a RTCP packet, which is OK by itself, but handles resulting ICMP in a strange way. I'll extend RTP proxy to make it relaying RTCP traffic as well (I am having it on a TODO list for a quite some time now), which should fix this problem.
Thank you for the debugging!
In the meantime, disabling RTCP in X-Ten should solve the problem.

- 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 ?

Adrian,
Do you have an Etheral trace trace of such a call (using G711)?
I guess ethereal traces can be generated with ethereal program and decoded locally on your servers if you want to isolate this.
I can decode it and produce an audio file for all to examine.
This way we
can get to the bottom of this. Thanks, Ricardo
