Changing:
onreply_route[handle_nat] {
if (nat_uac_test("private-contact")) {
fix_nated_contact();
}
if ($socket_in =~ "wss") {
fix_nated_contact();
}
if (has_body_part("application/sdp") && t_check_status("200")) {
route(RTPENGINE);
}
}
with:
onreply_route[handle_nat] {
if ($socket_in =~ "wss") {
fix_nated_contact();
} else {
if (nat_uac_test("private-contact")) {
fix_nated_contact();
}
}
*if (has_body_part("application/sdp") && (t_check_status("200") ||
t_check_status("183"))) {*
route(RTPENGINE);
}
}
solve the issue
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
Thank you. Very soon a Tutorial about WetRTC and calls UDP -> WSS WSS ->
UDP branch based.

Hello,
yes call record_route function here:
# record routing
if (!is_method("REGISTER|MESSAGE"))
record_route();
and fix_nated_contact here:
onreply_route[handle_nat] {
if (nat_uac_test("private-contact")) {
fix_nated_contact();
}
if ($socket_in =~ "wss") {
fix_nated_contact();
}
if (has_body_part("application/sdp") && t_check_status("200")) {
route(RTPENGINE);
}
}
Regards

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

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
