Abstract: A cellular based universal telephone system adapted for both cellular and land line service uses cellular service for both out-of-home mobile communications, and mimics land line service inside of homes by connecting one or more cellular handsets to a converter unit, which converter unit is connected to the home telephone wiring. Several off-the-shelf, non-cellular handsets can be connected to the telephone wiring (and hence to the converter unit), for answering and placing telephone calls involving the cellular telephone number. The converter unit contains a mobile converter unit and a land line interface unit. The mobile converter unit converts cellular signals from the cellular handset(s) into land line signals understandable by or needed by the non-cellular handsets, such as ringing signals, message waiting signals and call waiting tones.
