Screening Out Prank Calls

Iconoculture: Forget the doors and windows; the easiest way into most homes is through the telephone. Now two U.K. inventors have created a device that automatically screens out telemarketers, prank callers and phone scammers. TrueCall blocks telemarketers’ numbers while letting trusted peeps through.
If it doesn’t recognize the dialer’s number, TrueCall sends callers to a purgatory where they must identify themselves and wait for approval from the person they’re trying to call.
TrueCall combines that solution with the ability to connect to a database of known telemarketers, scammers and other unwelcome commercial callers. That’s ultimate customizable control over who gets through and who doesn’t.
