[Asterisk-Users] SIP phone registering problem

[Richard Airlie]

I am clearly doing something ridiculously wrong.

Running Asterisk 0.7.2 on FreeBSD 5.1, I have SIP soft phones which are
unable to register. They keep trying and then time out.

With the sip debug on in Asterisk nothing is logged.
Here is the trace from one of the phones (kphone):

(192.168.100.13 is kphone, 192.168.100.3 is Asterisk)

(and so it continues)

Seems like the REGISTER messages are being recieved at Asterisk but
then just echoed back to the SIP phone? What am I doing wrong?

thanks!
