Abstract:
A home gateway includes a WAN interface portion, a LAN interface portion and an analog interface portion, and a LAN controller, an analog controller and a central controller. The WAN interface portion communicates with an external telephone set. The LAN interface portion communicates with a plurality of telephone sets configuring an IP telephone system. The LAN controller and the analog controller control the LAN interface portion and the analog interface portion such that type information is transmitted to a destination telephone set. The central controller generates the type information in accordance with a type of information to be communicated to the external telephone set, based on the information received by the WAN interface portion. Thus, a user can readily determine which telephone set is to be used to receive a call when a plurality of telephone sets can receive a call from a calling party.
