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
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.

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 ?
