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. Answering machines, Fax machines, and even voice mail - none of these will pick up either. Yet outgoing calls are completely unaffected and go through normally! The target has no idea there's anything wrong, they'll just begin to think that they've become very unpopular as nobody calls them anymore, or even leaves them messages. If installation of this device happens to be on a business line, the potential consequences are even greater. Installs anywhere along the telephone line; it comes with both a modular plug connector (to fit in standard telephone jacks) and spade-lugs connector for installations in unconventional, difficult-to-find locations. Size: 2.5" x 1" x .75".

These devices are from a group of products which were developed for a special unit of a particular federal agency whose requirements included having capabilities of telephonically-based harassment campaigns which could be quickly and easily implemented as a component of certain covert operations. Some of those products are now offered for non-government sales for the first time. These are unique specialized devices which have few, if any, conventional applications. These are electronic tools for those who require innovative, serious revenge/harassment capabilities, or for those who just have an interest in unusual telephone devices. Designed for use on single-line telephone systems.

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.
