Abstract: A relaying device includes an uplink interface that continuously receives an audio signal in communication, a wireless apparatus interface to which a repeater acting as a wireless relaying apparatus is connected, a voice buffer that buffers the audio signal, and a control unit. The control unit performs a VOX processing of detecting whether or not a level of the audio signal is equal to or higher than a preset threshold. When the level of the audio signal is equal to or higher than the threshold, the control unit starts buffering the audio signal in the voice buffer, and requests the repeater to reserve a channel. After receiving, from the repeater, a reply indicating that a channel has been reserved, the control unit reads the buffered audio signal from the voice buffer, and transfers this audio signal to the repeater.

Abstract: The present invention relates to a relaying device which performs the individual calling in response to not only a call incoming from a telephone but also a call incoming from a transceiver. When receiving a communication request from another device over a network, the relaying device determines if this communication request is accompanied by the wireless-device specifying information (ID). When the communication request is not accompanied by the ID, the relaying device sends a signal for prompting another device to input the ID. When the ID is sent in response to the sent signal, the relaying device instructs the relaying wireless device to call the wireless terminal device specified by this ID. In addition, when the communication request is accompanied by the ID, the relaying device instructs the relaying wireless device to call the wireless terminal device specified by this ID.

Abstract: [Problem] To realize an audio communication system in which a relay device and terminal devices are connected via a communication network, and the relay device manages a group of the terminal devices. [Solution] The relay device is provided with a network communication unit, a control unit, and a session table. The network communication unit receives, from the 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.
