<p>Dear OpenSIPS-users;</p>
<p><br>
</p>
<p>My OpenSIPS is behind a NAT. The public IP is xxx.xxx.xxx.xx.
<br>
</p>
<p>So, I have configured advertised_address="xxx.xxx.xxx.xx" in
my OpenSIPS.</p>
<p><br>
</p>
<p>It seems that such new configurations takes appropriated
effect, because a <i>
Record</i>-<i>Route</i> header field in a SIP OK message
(for a call that was answered) contains the IP xxx.xxx.xxx.xx,
when it arrives to the caller (OpenSIPS adds Record-Rout
xxx.xxx.xxx.xx when the SIP INVITE is forwarded).
<br>
</p>
<p><br>
</p>
<p>So, when the caller receives that SIP OK it sends the SIP ACK
to IP xxx.xxx.xxx.xx, port 5060. Then OpenSIPS receives the
SIP ACK that has Route header field containing the IP
xxx.xxx.xxx.xx.</p>
<p><br>
</p>
<p>Now the problem: OpenSIPS refuses the SIP ACK as this message
was to another proxy and forward it. As log as the route is
xxx.xxx.xxx.xx, the SIP ACK returns to OpenSIPS that forward
it again. It becomes a loop.
<br>
</p>
<p><br>
</p>
<p>How to solve this issue? I think there is an error in my
OpenSIPS.cfg file.</p>
<p>Any hint?</p>
