Something like maxmind.com does...

A simple callback could be easy and deters 99% of fraudsters, no hack wants
to talk to someone when trying to screw them over.

Maxmind pushes it by adding around 15 variables like free or not email, geo
ip location vs npa-nxx etc but just a callback is nice.
We have a project that should rise this winter that will not only
revolutionize the way Voip providers work, but would fix that problem as
well
