Abstract

A call forwarding device (11) for forwarding phone (15) that is connected by a single forwarding phone line (13, 14) to central exchange telephone equipment (12). Equipment (12) has an electronic switching system and provides three-way conference service to the forwarding phone. In the call forwarding mode, in response to a call from a calling phone (17) to the forwarding phone, the device has circuits including a ring detector (31), a hook condition simulator (29) and a sensor (31) that automatically operate to simulate an off-hook condition, to simulate a first hook switch flash condition, and operates to actuate a message transmitting and storage device (25) which generates telephone dialing pulses corresponding to the number of a third phone (21), and to simulate a second hook switch flash condition, whereby the calling phone is automatically connected by the equipment (12) to a third phone. In a reprogramming mode, circuits including a sensor (33) in combination with the device (25) operate so that the device (25) may be reprogrammed with any third phone number to change the telephone number to which the call is forwarded and reset for receiving the next call or a new phone number.
