A system for selectively answering a telephone from a remote location is disclosed herein. The system basically includes both a stationary unit and a portable unit. The stationary unit, first of all, is connectable in line with a telephone line extending to a telephone. The stationary unit includes a ring detector circuit for activating the system upon detecting a ringing signal received over the telephone line, a first antenna with transmitter-receiver, a switching circuit for seizing the telephone line, and an enclosure. The portable unit, on the other hand, may be carried on-person. The portable unit includes a second antenna with transmitter-receiver for establishing electromagnetic communication with the first antenna, an activatable switch for selectively triggering seizure of the telephone line in response to any ringing signal that is detected, a microphone for transmitting verbal communications over the telephone line whenever the telephone line is seized, and a casing.
