WOW! In these past couple yrs the telemarketing and phone scams has gotten really bad. I sometimes wonder if it's the same people who make or sell call blocking devices  to drive up business  I just don't answer unknown calls anymore, if it's someone I know or important they'd leave a message.

They use software to create fake numbers and then have a cumputer call thousands of people and  then they can tell if a person or machine or fax picks up. If a person picks up they know and then it will send that info to people running the scams and you'll probably get a lot more calls from different people with different numbers running different scams. Just don't pick up unknown calls from unknown areas anymore, if it's someone u know or important they will leave a message. It sucks it has come to this .
