I don't know the RFC well enough, but as every other protocol works I think it's a kamailio bug. You should be able to reproduce this, I don't think I've done anything special.

Inspect the received ACK (log $mb) and check the RURI, and Route headers. Maybe the show some bugs. Also, if you manually apply routing to in-dialog requests (e.g. forcing the send socket) make sure to not make mistakes.

hi
I have set up tls on kamailio successfully, but when I relay a TLS client to an other proxy ($ru = "sip:" + $rU + "@" + "127.0.0.1:5070;transport=udp";) via udp I get error messages.
From the timing it seems like this warning always appears after I get 200OK from proxy, the Invite gets sent correctly, but kamailio seems to fail while sending back the ACK.
18(11231) WARNING: <core> [forward.c:270]: WARNING: get_send_socket: protocol/port mismatch (forced udp:77.180.86.63:5060, to tls:127.0.0.1:5070)
TCP->UDP works. TCP->TCP works. UDP->UDP works. UDP->TCP works. TLS->TCP works. TLS->UDP doesn't work.
