Abstract
[Problem] To provide an audio communication system in which a relaying device is connected to terminal devices via a communication network and said terminal devices communicate with each other on the basis of assignments for said terminal devices. [Solution] This relaying device is provided with a network communication unit, a storage unit, and a control unit. The network communication unit is connected to a communication network and communicates with a plurality of terminal devices over said communication network. The storage device assigns each terminal device to one of a plurality of subsystems and stores, for each terminal device, the assigned subsystem and identifying information. When an audio signal is received from a given terminal device, the control unit identifies the subsystem to which said terminal device is assigned from originating-terminal-device information attached to the audio signal and forwards the audio signal to another terminal device assigned to the identified subsystem. The terminal devices transmit audio signals to the relaying device, each of said audio signals having forwarding-destination information that specifies the forwarding destination for said audio signal attached thereto.
