I agree that the transport used to send a request is indicated in Via header but the selection of this transport used to reach next hop is done by applying procedures in rfc 3263 to Request URI or URI in route header.
So if the request uri is sip:[email protected]:5061 should the transport be resolved to udp or tls? I have a scenario where I have to send a request over TLS using sip scheme without using transport=tls parameter since it is deprecated. Is this possible ? Please point me to what should be done as per standards.
