Are you allowing unauthenticated calls from spce peer or globally? If it's the
second you should remove that. Use the "insecure" setting in sip.conf, but
never "allowguest"

Example for a 1.4 box (should more or less work the same for newer versions)

What's your register line, you sip peer configuration at sip.conf and what's
the ngrep-sip of those registrations?

If you have a static public ip you can leave the asterisk as subscriber but
don't register it (you can fake a permanent contact for it) 

YOu can also trust the ip address and don't request authentication (check the
trusted preferences.) But don't make it because you have asterisk configuration
problems. Better to debug them first.

As subscriber.

The user won't be bale to make calls (the authentication process is never
reached for banned users) until the ban expires because it's banned. This
prevents brute force attacks against user/password.
