Abstract
Abstract A cordless telephone provides both basic and enhanced features that are accessible through the combination of a portable unit and an auxiliary recharge cradle, some of these features being heretofore available only at a base unit which combines a cordless telephone fixed station and a telephone answering device. The cordless telephone includes a call screening feature which allows a user at the portable unit to monitor incoming messages received over telephone lines as they are being recorded at the telephone answering device. A loudspeaker is incorporated into the recharge cradle and, while the portable unit is in this recharge cradle, a user may configure the portable unit and cradle in a manner to monitor the incoming messages through the loudspeaker. An incoming message is received by the portable unit through a radio frequency link commonly shared by this unit and the base unit and then advantageously coupled from the portable unit via optical devices to amplifying circuitry in the recharge cradle for driving the loudspeaker. The amplifying circuitry is turned on upon receipt of the ringing signal by the portable unit. Once receipt of the incoming message is completed, the amplifier circuitry is turned off. The cordless telephone also includes a caller-ID feature which permits the user of the portable unit to selectably identify certain incoming messages for generation by the loudspeaker. In this aspect of the invention, the user of the portable unit is advantageously provided with incoming messages only from pre-identified calling parties and can listen to a message from one of these parties before the call is answered. This operation is achieved by the user entering into a memory table is the telephone each one of a plurality of desired telephone members for subsequent comparison with a caller ID number received from a calling party.
