Abstract:
1. A communication system comprising: a communication device configured to connect with a communication line; a first phone device; and a second phone device, the communication system configured to connect the communication device, the first phone device, and the second phone device with each other via wireless communication, wherein the communication device comprises: wherein the first phone device comprises a first-phone-device storage unit configured to store the first-phone-device network ID and the communication-device network ID, wherein the communication system is configured to switch a communication state thereof from a first communication state, in which the wireless communication unit performs both data communication with the external device and voice communication with the first phone device and the second phone device, to a second communication state, in which voice communication between the wireless communication unit and the second phone device is performed separately from data communication between the first phone device and the external device, by changing settings of the communication-device network ID and the first-phone-device network ID stored in the communication-device storage unit and the first-phone-device storage unit when voice communication is started using the second phone device in response to an incoming call from the communication line, wherein the first communication state is set when the communication-device network ID is used for the communication device such that the communication device is recognized as the communication device on the communication system, the first-phone-device network ID is used for the first phone device such that the first phone device is recognized as the first phone device on the communication system, and a communication party device of the external device, the first phone device, and the second phone device is set to the communication device for which the communication-device network ID is used, and wherein the second communication state is set when the first-phone-device network ID is used for the communication device such that the communication device is recognized as the first phone device on the communication system, the communication-device network ID is used for the first phone device such that the first phone device is recognized as the communication device on the communication system, and a communication party device of the second phone device is set to the communication device for which the first-phone-device network ID is used.
