Via header force change protocol to TLS?
I have kamailio behind a TLS termination proxy so the sockets are correctly deduced to be TCP. However the clients only talk TLS to the proxy and are confused when the top Via header added by Kamailio is TCP. Is there a way for Kamailio to forcibly pretend its protocol is TLS? Like advertised_address but "advertised_protocol" instead. (With pjsip testing: it has a flag use_tls which ignores TCP from Kamailio and continues to use the persistent TLS transport to proxy. Linphone fails because it tries to honor TCP in Via and is unable to establish TCP transport). BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy as TCP even though the contact addresses specify transport=TLS.

BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy as TCP even though the contact addresses specify transport=TLS. there is no advertise_protocol as far as I know. If you want to go down the route with a patch to the C code, you have to be careful at TLS callbacks, because if the protocol is detected to be tls, some encryption/decryption callbacks may be executed. I am not sure how much, or if any, the impact is, just throwing it as a notice in advance.

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!
