How does the TeleZapper II “zap” telemarketers?
The TeleZapper II uses the technology of telemarketers’ automatic dialing equipment against them. When you or your answering machine picks up a call, the TeleZapper II emits a special tone that “fools” the computer into thinking your number is disconnected. When the computer hears the tone, it hangs up before you can be connected to a telemarketer and then deletes your phone number from its database. Overtime, 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.
