TeleZapper
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The TeleZapper is a device designed to reduce the number of telemarketing-related phone calls a household receives by imitating the tone signal normally played by a phone company to indicate a line has been disconnected. The Telezapper was created by Privacy Technologies, Inc, a wholly owned subsidiary of Royal Appliance Mfg. Co.Telemarketing companies typically use predictive dialers to place many calls at one time. When this equipment detects that someone has answered one of the many calls it has made, it quickly transfers that call to an available agent. Calls which don't answer or numbers that are disconnected are not transferred to agents and the call is terminated automatically.
