  • EXCHANGE, AND TELEPHONE EXCHANGE METHOD
    Publication number: 20240223703
    Abstract: To enable provision of various extension services to a terminal apparatus connected to an external exchange. A first gateway (12) registers an extension number of a terminal apparatus (30) to an extension control means (11). A flow control means (13) routes an outgoing call originated from the terminal apparatus (30) and an outgoing call addressed to the terminal apparatus (30) between the first gateway (12) and a second gateway (14). When receiving the outgoing call originated from the terminal apparatus (30) from the first gateway (12), the extension control means (11) processes the outgoing call as an outgoing call from the extension number of the terminal apparatus (30). In addition, when an outgoing call addressed to the extension number of the terminal apparatus (30) is made, the extension control means (11) transmits the outgoing call addressed to the terminal apparatus (30) to the first gateway (12).
