<p>Hello,</p>
<p>afaik, one rtpproxy instance can listen on a single IP for RTP
traffic, or two if started in bridging mode. Typically 0.0.0.0 is
about listening on any and in such cases applications can have
different behaviour. If you want a single RTP relay to listen on
many ip addresses and just forward rtp or do bridging, then look
at rtpengine, is more flexible with these options (at least
compared to rtpproxy from 2-3 years ago, when I used it more,
because since its package was removed from debian stable, no
longer having the convenience of apt install for small voip
systems, I just deploy rtpengine).</p>
<p>Cheers,<br>
Daniel<br>

<div>A bit of debug in rtpproxy: I found out that if I use -l
10.10.111.234 instead of -l 0.0.0.0 in the command line, it's
working as expected.</div>

Hi,
<div><br>
</div>
<div>I have 2 hosts on AWS behind NAT:</div>
<div><br>
</div>
<div>One with rtpproxy:</div>
<div><br>
</div>
<div>/usr/local/bin/rtpproxy -f -p
/run/rtpproxy/rtpproxy.pid -s udp:<a
href="http://0.0.0.0:31500" target="_blank"
moz-do-not-send="true">0.0.0.0:31500</a> -A <a
href="http://15.236.230.177/15.236.230.177"
target="_blank" moz-do-not-send="true">15.236.230.177</a> -l
<a href="http://0.0.0.0/0.0.0.0" target="_blank"
moz-do-not-send="true">0.0.0.0</a> -m 35000 -M 65000
-d DBUG:LOG_LOCAL5 -u rtpproxy:rtpproxy -F</div>
<div><br>
</div>
<div>The other one, with a kamailio and using
only rtpproxy_manage(); without parameters.</div>
<div><br>
</div>
<div>I'm surprised because in my SDP being modified,
kamailio is replacing with its KAMILIO private IP.
(not the rtpproxy one)</div>
<div><br>
</div>
<div>I see that rtpproxy and kamailio are exchanging
data. Nothing obvious is coming out.</div>
<div><br>
</div>
<div>Any obvious mistakes?<br clear="all">
<div>Anything you need to help?</div>
<div>Should I switch to another rtp engine?</div>
<div><br>
</div>
<div>Regards</div>
