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

Good morning everyone,
I'm trying to implement this type of scenario:
WSS -> load_balancer -> UDP Gateway (Asterisk)
Everything works up to the 200 OK received from the gateway and
forwarded from OpenSIPs to the WebRTC clients.
I don't see the ACK sent from the WebRTC client to OpenSIPs to commit
the 200OK.
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.
I'm writing a tutorial, for now in Spanish, dedicated to the subject but
without that piece I can't finish it.
Thank you in advance for the help
