Abstract

A communication system includes an exchange, one or a plurality of telephones connected to the exchange via a telephone circuit network, and one or a plurality of computers connected to the exchange at least via the telephone circuit network. Among those telephones and computers, a first telephone is correlated with a first computer. The first telephone sends the first computer a first call reception state report indicating a call reception state of the first telephone via a first route. When receiving the first call reception state report, the first computer sends the exchange a prescribed telephone circuit control instruction for a call directed to the first telephone. When receiving the prescribed telephone circuit control instruction, the exchange performs a telephone circuit control for the call directed to the first telephone according to the prescribed telephone circuit control instruction.
