Are there any international phone number black list databases out there?
We currently only allow international calls during normal business hours,
have daily quotas and have a user access pin code. I am always looking for
more options to prevent fraud.

I found that doing a reverse on the IP to regular spam RBLs results in
hits on most attempts to connect.

interest in seeing that come to fruition?
