route(RTPENGINE);<br>
}<br>
}</p>
<p>solve the issue<br>
</p>
<p>This because my UDP SIP trunk reply with a 183 with SDP Annex
while call between users (UDP or WebRTC) reply with 180 Ringing
without Annex<br>
</p>
<p>Thank you. Very soon a Tutorial about WetRTC and calls UDP ->
WSS WSS -> UDP branch based.<br>

<p>Hello,</p>
<p>yes call record_route function here:</p>
<p># record routing<br>
if (!is_method("REGISTER|MESSAGE"))<br>
record_route();</p>
<p>and fix_nated_contact here:</p>
<p>onreply_route[handle_nat] {<br>

<br>
Are you calling record_route? Also, make sure you call
fix_nated_contact() on the 200 OK. Read this blog post for more

<blockquote type="cite">Good morning everyone, <br>
<br>
I'm trying to implement this type of scenario: <br>
<br>
WSS -> load_balancer -> UDP Gateway (Asterisk) <br>
<br>
Everything works up to the 200 OK received from the gateway
and forwarded from OpenSIPs to the WebRTC clients. <br>
<br>
I don't see the ACK sent from the WebRTC client to OpenSIPs to
commit the 200OK. <br>
<br>
WebRTC -> UDP and UDP -> WebRTC calls between users work
correctly and analyzing the 200 OK of a call between users and
a call via load_balancer, the truth is that I do not find
differences that justify this type of error. <br>
<br>
I'm writing a tutorial, for now in Spanish, dedicated to the
subject but without that piece I can't finish it. <br>
<br>
Thank you in advance for the help <br>
