Hi Gang

To increase security against phished passwords and similar attacks, we
consider offering customers to define IP ranges (or GeoIP locations)
from which their dynamic registrations are being accepted.

I can already look at the source IP in the dial plan, so no issue with
validate an INVITE against a source IP.

But I would also like to prevent registrations from outside of this
client's specific allowed ip addresses as well, so the line cannot be

So I'm looking for something like

On Register:
If check_allowed_ip(auth_username) {
} else {
	Reply(403 Wrong IP for this user);

Any ideas how to do that? (Yes, I asked Google and found nothing
useful yet)

Mit freundlichen Grüssen
