Abstract
A first gateway registers an extension number of a terminal apparatus to an extension control means. A flow control means routes an outgoing call originated from the terminal apparatus and an outgoing call addressed to the terminal apparatus between the first gateway and a second gateway. When receiving the outgoing call originated from the terminal apparatus from the first gateway, the extension control means processes the outgoing call as an outgoing call from the extension number of the terminal apparatus. In addition, when an outgoing call addressed to the extension number of the terminal apparatus is made, the extension control means transmits the outgoing call addressed to the terminal apparatus to the first gateway.
