I think the sip-implementors sip-implementors@cs.columbia.edu or sip sip@ietf.org mailinglist could help you more.

Hi,
We are also having a problem with X-Pro and X-lite build 1088 when registering to a SIP proxy based on libosip. The X-Pro is not using the double-quotes on the nonce value of the Authorization header, which is causing an error on our proxy when parsing of this header (Libosip requires the double quotes). I have sent this question to the Xten support forum but they said that the double quotes are not mandatory, though libosip requires them.
Any thoughts on what is the correct behaviour of the double-quotes on the authorization header?
Thanks, Chuck

PS: nevertheless build 1095 (as 1088) is IMO buggy as it doesn't register to my default proxy, but to all other configured proxies. Any solutions?

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.

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
- 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
&! gt; 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
&g! 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
