The TeleZapper uses the technology of telemarketers’ automatic dialing equipment against them. When you or your answering machine PICKS up a call, the TeleZapper emits a special tone that “fools” the computer into thinking your number is disconnected. Instead of connecting you to a salesperson, the computer STORES your number as disconnected in its DATABASE. Over TIME, as your number is REMOVED from more and more databases, you’ll see a dramatic decrease in the number of annoying telemarketing calls you receive.
