    Patent number: 5410593
    Abstract: A hold displaying system includes plural multifunction telephone sets each of which has a hold indicator, and an exchange for accommodating the telephone sets. Each multifunction telephone set cooperates with the exchange to perform a hold display on the hold indicator of the respective multifunction telephone set. When information for a multifunction telephone set to which a hold display is forwarded is sent from a multifunction telephone set on a hold operating side to the exchange, the exchange transmits its hold display switching information to the multifunction telephone set to which the hold display was forwarded, whereby the hold indicator indicates the same hold display as that provided by the multifunction telephone set to which a hold display has been forwarded during its holding operation.
