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

When I send a similar UDP register, it works fine!
