Caller ID shows this number---However, this is a Spoofed Number - no such number exists. More & more crooks are doing this While illegal, the software is available cheap. see Itellas.com Your call blocker won't help much if they show different Caller ID each time they call. The only thing you can do is use a Call Blocker where you receive calls from an "Invited List" only and block all the rest. Too bad it has come to this (FCC DNC Program failure), but if we all use the Invited List approach, then these crooks will be out of business.
