Patent
CA 2035716
A private branch exchange system having a call forward busy function wherein, when a busy incoming- call destination terminal receives a further incoming call, the further incoming call is informed to both of the busy incoming-call destination terminal and a forwarding destination terminal previously set for the busy incoming-call destination terminal. Since a response opportunity to the further incoming call is provided even when the initially- intended incoming-call destination terminal is busy, the response opportunity of the busy incoming-call destination terminal and the forwarding destination terminal to the incoming call can be increased and therefore an incoming-call response rate of the entire system based on the call forward busy function can be increased.
