Hello.
I'm trying to deploy Opensips  as a front-end for TLS-UDP translation, as a
back-end would be FreeSWITCH.
TLS -> Opensips -> UDP -> FreeSWITCH
TLS work fine end point is registered. But when freeswitch send invite he
tries use TLS instead of UDP. I understand the problem in  "transport=tls"

Example register message:

REGISTER sip:10.222.0.22 SIP/2.0
Record-Route: <sip:10.222.0.22;r2=on;lr=on>
Record-Route: <sip:10.222.0.22;transport=tls;r2=on;lr=on>
