Stop Anonymous Phone Calls / Pubbli Stop
Anonymous phone call reject circuit: Made for POTS analogic phone lines, this circuit analyses the Caller Identifier data (CLIP) sent between the two first call rings of incoming phone calls, rejecting any P (Private) or O (Out of area) calls types. Fully tested in Europe. No batteries required: It takes energy directly from the phone line, surging less than 1 mA.
