[SR-Users] Re: Via header force change protocol to TLS?

Hello Sergey, Thanks for the suggestion. Not sure if his is what i'm looking for, allow me to explain further: We set up an NetworkLoadBalancer on AWS to offload tls on it. This Load balancer is a TLS listener on the outside and a TCP connection to the proxy inside. So when sending an INVITE to the connected client, the via has a TCP protocol like Via: SIP/2.0/TCP mydomain:port;branch=z9hG4bKf176.53ac8af0d7090a31e44548f15ea420ff.0 and the client (linphone) disconnects and tries to contact the proxy on that address on a TCP socket, which doesn't exist. I tried many solutions none of which actually work... last one setting $du =$du + ";transport=tls" and forcing the socket to the TCP socket to the load balancer, but of course i'm getting warnings about this. is this something that PR (not merged) would be addressing, i didn't see that. If not, is there a way of doing this without any trickery? Thanks!
