------------------------------------------------------------

Hello,

My issue was that if the TRANSPORT for the ENDPOINT is TCP.

Asterisk SHOULD NOT reply to its UDP REGISTER with OK on UDP, As seen in the pjsip output instead it should either pretend it didn't get the message or respond with a NOT AUTHORIZED as it does for further REGISTER attempts via UDP.

> *Create an Endpoint with TCP as transport
> * Use dynamic registration
> * Set a phone to use UDP instead to register as endpoint
> First registration attempt as UDP will be accepted by Asterisk with 200 OK
> Asterisk then flags AOR as available, then immediately removes the contact as it is UDP.
> From then on phone gets correct 401 - REFUSED to any further attempts to register / call out.
> Will attach test case shortly
