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

New subject: [Serusers] Re: Xten-RTPProxy choppy audio
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.
Regards,
Ricardo

3. RTP Stream from ATA to Xten is perfect and conserves the same

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

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 ?

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

New subject: [Serusers] Re: Xten-RTPProxy choppy audio
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).

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.

Ricardo

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 ?

I guess ethereal traces can be generated with ethereal program and

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.
