<tt>Hi Aqs,</tt><tt><br>
</tt><tt>rtpproxy should start relaying immediately to the port
specified in the SDP. If the UA sends UDP packets from another
source:IP port, it should update internal session data, so that
all subsequent packets will be relayed to the proper IP:port.
Otherwise it will continue to user the same IP:port specified in
the SDP.<br>
<br>
Is the IP in the SDP negotiation correct (the public one, and not
the local one) ?<br>

<div>It looks a simple question but whats outgoing RTP
packets destination? Is CALLEE IP present on that NATed
destination?<br>
</div>
Confirm that RTP Proxy determined that NATed IPs properly.<br>

What did you receive in 200OK from CALLEE?<br>

Check if engaged RTP ports are open in the flow?<br>

<div>Greetings
list,
<div><br>
</div>
<div><br>
</div>
<div>I have
kamailio
server behind
nat with
rptproxy. But
i am getting
no voice on
the call.
After taking
trace i could
see that
rtpproxy was
getting rtp
packets but
not packets
was being
forwarded
towards callee
side. </div>
<div><br>
</div>
<div>Though i
see in
rtpproxy logs,
packets being
relayed from
caller side. </div>
<div><br>
</div>
<div>Does
rtpproxy wait
to receive a
single rtp
frame from
callee before
fowarding that
to callee?<br>
</div>
<div><br>
</div>
<div>Since, i am
getting no rtp
from callee.
So, might be
rptrpoxy is
waiting to
learn source
address of
callee side
rtp, that is
why it is not
forwarding rtp
packets from
caller towards
callee. </div>
<div><br>
</div>
<div><br>
</div>
<div>Any
pointer/suggestion
is much
appreciated.</div>
<div><br>
</div>
<div>Best
Regards, </div>
<div><br>
