With such a system, two users may maintain participation in a three-way conversation while being free to move about within reasonable transmitting distance to and from the base unit. Circuitry is provided in which a signal received from one handunit is transmitted to the other handunit, and sidetone from one handunit is transmitted back to that handunit.
