[Problem] To provide an audio communication system wherein a relay apparatus is connected to terminal apparatuses, which are communication devices, via a communication network and wherein the relay apparatus is caused to manage the group of the terminal apparatuses. [Solution] An audio communication system comprises: a master relay apparatus; one or more slave relay apparatuses connected to the master relay apparatus via a communication network; and one or more terminal apparatuses connected to each relay apparatus via a communication network. Each slave relay apparatus transfers, to the master relay apparatus, audio signals received from the terminal apparatuses in charge of that slave relay apparatus. The master relay apparatus transfers the audio signals, which were received from each slave relay apparatus, to the slave relay apparatuses other than that slave relay apparatus. |
