This tiny device allows the user to create "dead lines". When someone calls a line that employs this device, they will hear the phone ring and ring, however the target phones never ring because this device blocks the "trigger voltage" that causes a phone to ring. Comes complete with modular and spade connectors for all types of installations.This device prevents the phones from ringing on incoming calls. The calling party just hears the phone ringing and ringing, but it's never answered since the phones are silent on the target's end so they have no idea that someone is calling them.
WARNING: these devices are to be used only in a legal and lawful manner in compliance with all applicable laws and F.C.C. regulations, which should be consulted prior to connection of any equipment to telephone lines.
