Telephone message center

摘要

A telephone message system overcomes the problems and limitations of presently available systems that seek to enhance inter-and intra-premises communications. The system advantageously comprises a controller unit with Caller ID capabilities and one or more adjunct units that are bridged onto a single wire-pair at a user's residential location in a parallel electrical connection. These customer installable units are merely plugged into any telephone jack and share a telephone wire-pair with existing telephone extensions without interference. Such operation is possible since communication between the controller unit and the adjunct units is limited to a frequency band different from the audio frequency band used by the existing telephone extensions on the single wire-pair. The controller unit, in one configuration, operates as an answering machine with multiple mailboxes. This functionality is advantageously combined with Caller ID, intercom and speakerphone capabilities. The adjunct units may be added to any of existing telephone devices thereby providing access to the functions available at the controller unit throughout the premises.
