Kind Code:
A1
Abstract:
[Problem] To enable group communication with a high degree of freedom in a voice communication system in which a relay device and a terminal device are connected via a communication network. [Solution] A voice communication system comprises a terminal device and a relay device which transmit and receive a voice signal via a network. The relay device has a group table. The terminal device transmits, to the relay device, information designating a group to which the terminal device belongs. When receiving the information designating the group from the terminal device, the relay device registers, in the group table, an indication that the terminal device belongs to the designated group. The terminal device transmits, to the relay device, a voice signal directed to the group to which the terminal device belongs. When receiving, from the terminal device, the voice signal directed to the group to which the terminal device belongs, the relay device transfers the voice signal to another terminal device belonging to the designated group.
