Abstract
A relay device includes a network communication unit, a control unit, and a session table. The network communication unit receives, from terminal devices, an audio signal to which is attached information for designating the terminal device of the other party of communication. When a calling voice packet is received from one of the terminal devices, the control unit registers, in the session table, a communication session in which this terminal device and the terminal device designated by the designating information constitute participating terminals. Thereafter, the control unit transfers an audio signal received from one of the participating terminals to each of the participating terminals and, when an audio signal is received from two or more of the participating terminals at the same time, mixes the received audio signals and transmits the mixed audio signal to the participating terminals.
