Hi, Bertrand!
I believe the problem is the order of the Route headers generated by the
Application SRV. Can you also post the INVITE sent by OpenSIPS to the
Application SRV?
Best regards,
Răzvan

Hi,
I'm quite new to opensips and for a poc , I've built an Opensips gateway with
RTP-Engine module as webRTC gateway.
Client -(wss - public)-> R-proxy -(priv-wss)-> Opensips GW - (priv SIP/RTP)->
Application srv
It works fine with a basic dialin from the webrtc client and this even if the
client is behind a NAT... but now I've some difficulties when the called part
(an application server) is sending a ReInvite to the Calling Part
When the application server is sending back a ReInvite to the Opensips GW, The
Invite is sent to the proxy through SIP while wss transport is expected.
ReInvite received by Opensips:

Again from dialin Opensips is correctly receiving WSS messages on the WSS
listener (here, 10.108.1.11:443) and the OK is correctly sent to the calling
part with wss.
Any idea? Something wrong with this route (Route:
<sip:10.108.1.11:443;transport=wss;r2=on;lr>)? Any help is welcome.
Thx in advance,
Bertrand Gaudin
