For some reason, I am having problems with having TCP REGISTER messages being accepted by openser.
The following is a REGISTER I send to Open SER. It is never responded to. Do you see anything wrong with it? It should be registering port 5060 TCP.
00:19:42.157347 IP 10.10.2.6.50083 > 10.10.1.234.sip: tcp 345 REGISTER sip:siptest2.com:5060 SIP/2.0^M Via: SIP/2.0/TCP 10.10.2.6:50083;branch=z9hG4bK45^M From: Alice sip:alice@siptest2.com;tag=fromhackblah^M To: Alice sip:alice@siptest2.com^M CSeq: 1 REGISTER^M Call-ID: DNYEXXLURKQELGQLDAJXJADPKUJVSHKUZSFPYXDGQ@musecurity.com^M Contact: sip:alice@10.10.2.6;expires=900;transport=TCP^M Max-Forwards: 70^M ^M
When I send a similar UDP register, it works fine!
