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 in the telephone each one of a plurality of desired telephone numbers for subsequent comparison with a caller-ID number received from a calling party. In response to a favorable comparison between the caller-ID signal and any one of the stored telephone numbers, the incoming message being received over the telephoneline is automatically generated in the loudspeaker in the recharge cradle.
Cette invention concerne un téléphone sans cordon offrant des fonctionnalités de base et étendues accessibles au moyen d'un combiné portatif et d'un chargeur auxiliaire combinés, fonctionnalités dont certaines n'étaient jusqu'ici accessibles que via le bloc de base regroupant le poste émetteur-récepteur fixe et un répondeur automatique. Le téléphone sans cordon objet de l'invention comprend une fonction de filtrage des appels qui permet à l'utilisateur d'écouter via le combiné les messages entrants enregistrés par le répondeur. Le chargeur comporte un haut-parleur intégré qui peut servir à l'écoute des messages entrants lorsque le combiné se trouve sur le chargeur. Le combiné reçoit les messages entrants via une liaison radiofréquence exclusive au combiné et au poste fixe et les transmet avantageusement au moyen de dispositifs optiques à un circuit d'amplification prévu dans le chargeur pour alimenter le haut-parleur. Le circuit d'amplification se met en circuit à la réception du signal d'appel au combiné. Une fois le message entrant terminé, le circuit d'amplification se désactive automatiquement. Le téléphone sans cordon comporte également une fonction d'identification de l'appelant qui permet à l'utilisateur du combiné de forcer la transmission de messages choisis via le haut-parleur. Selon cet aspect de l'invention, l'usager du combiné a le choix d'écouter les messages de personnes choisies seulement et de décider à l'écoute s'il répondra ou non. Cette fonction suppose que l'usager a entré en mémoire les numéros de téléphone des appelants dont il souhaite pouvoir
