The telezapper is a thing that you hook up to your phone line, like an answering machine. Now you know how when you forget to dial the area code and you hear a beap then the message to hang up and try your call again? Well if a phone number is no longer in use, it does the same thing. If the telezapper senses that you recieved a phone call dialed by a computer, it makes a beep and the computer thinks that the phone number is no longer in use. It deletes the number off of its list. Since most of these calls that you get use the same list, you will reduce a lot of the calls that you get just by it picking up one of these calls.
