We need to actually discuss some form of infrastructure to broadcast these types of thing in a secure way as to prevent false positives. /b On Aug 16, 2013, at 10:17 AM, Ira Tessler <ira@connectmevoice.com> wrote:
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.
Thanks!

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

Ken and I talked about building something into e164.org to allow you to do dnsbl-like queries there and get info on a specific IP or TN. Any interest in seeing that come to fruition?
There are obvious issues with being able to verify that a TN really belongs to the person calling you (not being spoofed), but maybe the STIR workgroup stuff will help in that regard (in a year or two?).
