Simple Phone Tap


This circuit is extremely simple, therefore there is less chance of any problems. It can be placed anywhere on the phone line and it will record any conversation on any phone on that line.

Please note: I have received several emails saying that this circuit will not work and that it may hold your line off hook and to me it looks like it will. Build at your own risk.
