ABSTRACT:
A telephone set is provided that includes a control section that, when detecting an off-hook operation, instructs a tone generator and a codec to stop a transmission of an incoming call and simultaneously instructs, using an awaiting voice generation instructing function section, the tone generator to produce a signal voice informing an awaiting state and the codec to transmit it to a handset. At the same time, the control section generates an off-hook signal and transmits it to a packeting section. The off-hook signal is incorporated in the packet to be transmitted by the packeting section and is transmitted from a packet network interface to a packet network.
