Unable to register with Gatekeeper

I'm currently running Ekiga 2.02 on FreeBSD v6 and v7
systems. I am
attempting to register with the Gatekeeper, but I am not
having much
luck. I am assured that this works fine on Linux systems, so
I assume ti
is a FreeBSD specific issue or I have made an error in
configuring the
GK.

Any suggestions would be welcome. I really need to get this
working
fairly soon and suspect it is something fairly trivial.
