The national "Do Not Call List" is about as effective as the "do not walk" signs at intersections; telemarketers pay no attention to it. But there's an app that'll hang up on the scammers and spammers.
Aaron Foss is the founder of Nomorobo, an app that promises to stop robocalls.
"We're actually detecting over 1,200 new numbers a day."
Foss says they can tell which calls are bogus.
"When they're calling a thousand or 5,000 people in a matter of a couple of hours from one number -- that immediately gets on our blacklist."
Foss says Nomorobo can also protect land lines -- for free -- just sign up at their web site.
"Go to nomorobo.com; put in your phone number and your carrier and we give you instructions on how to turn it on on your land line. It takes just a couple of minutes and you're protected and the best part about it on land line is it's completely free."
Foss says his technology can spot those who robo dial you -- no matter number comes up on your caller ID.
