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

<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
