The federal Do-Not-Call registry turns 10-years-old this summer, but the calls keep coming. Just last year, the federal government received 600,000 telemarketing complaints.
Will Maxson at the Federal Trade Commission says new technology called "caller ID spoofing" allows scammers to hide their identity from anywhere in the world.
“Even when they're calling you from somewhere overseas they can be calling you with a phone number that makes it look like they're in the same area code as you,” Maxson tells KTRH News.
That's why former NASA engineer Alfredo Purrinos and others are designing devices to combat that, such as the “T-Lock Call Blocker” for your home phone.
“It doesn't work directly on a cell phone, but you could forward your cell calls to a land line and block it there,” says Purrinos.
Those devices help, but loopholes in the law still allow survey calls, and calls from companies you've done business with in the past 18 months.
Maxson insists the FTC is cracking down on all others.
“We've now filed over 100 Do-Not-Call cases, many of those cases are still in court, still ongoing,” he says. “But of the ones we've completed, we've collected over $80 million.”
Maxson says anyone still receiving robocalls after they registered their number on the Do-Not-Call registry should report it to the agency.
The state of Texas also has it's own separate Do-Not-Call list. However, your number only stays registered for three years, then has to be re-listed.
