Who called from 7206398575

Called our business and CID said "FAX BLOCK, ME". I decided to ignore the call and no message was left on VM. Less than five minutes later, I get a call from "Out of Area" with a fax machine noise. This follows up the fax machine beeping left on the VM at 10:00 PM last night. You can't fax a phone line!

What are you talking about?
Fax machines work on phone lines !!
But a fax machine cannot work when calling a voice telephone or answering machine.

There is a website " faxblock.me " owned by someone in the Phillipines, the IP address is in England, and hosted on servers in the Netherlands.
http://whois.domaintools.com/faxblock.me

The home page is a generic Apache HTTP Server Test Page, which means it possibly isn't set up, despite it being over a year old.

Believe or not, there are websites that harvest fax numbers and then allege they will put your fax number on a Do-Not-Call list ...
