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:

Message Body
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
