Abstract

A user programmable telephone call screening device which screens incoming telephone calls by comparing a caller's identifying code to user programed codes and either diverting the call, without ringing the phone, to an answering device or ringing the phone for pickup by the intended recipient. The screening device is automatically deactivated to permit all incoming calls to ring through after an out going 911 or other user defined emergency call is made. The screening device also functions to permit the user to look up and automatically dial a call to phone numbers entered into the screening device's memory by the user. The screening device's programmable CPU and memory permit many functions to be incorporated into the device including, in-coming and out-going call blocking by area code, phone number and time of day, call forwarding, pager notification and recording out-going call information to permit the user to verify calls against telephone company billing records or for other purposes.
