TeleZapper - NIB

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. I purchased this for my family, who like the rest of us are over RoboCallers. They did not want it and I couldn't return it as they gave it back to me way too late. I have no idea how it works etc but since Poshmark just started with electronics I thought why not post it. I no longer have a land line to try it for myself. Do you want to give it a go?? :)
