Summary:                    Asterisk retransmits the 401 response of failed
REGISTER
Description: 
Hi! Asterisk retransmits the 401 of a failed REGISTER. This is buggy as
there will not be an ACK for REGISTER, does Asterisk must not retransmit
any response in a REGISTER transaction - except the incoming REGISTER
itself is a retransmission!

I found out that the problem exists only when alwaysauthreject = yes.

Thus I reviewd the code and found that the transmit_fake_auth_response
function was called with "reliable=1" which is false.

Attached is a patch.
