    • PROBLEM TO BE SOLVED: To provide a telephone system by which a person logs in the system regardless of a place. SOLUTION: In addition to a node information DB which is a data base formed by making exchanges in the telephone system correspond IP addresses, the other node user information DB which is a data base formed by making the extension number of the IP terminal correspond with the identifier of an exchange at a prescribed connecting destination is stored in each exchange. Then, when a connection request is transmitted from the IP terminal to the exchange, the exchange notifies an IP terminal at a requesting source of the IP address of an exchange at a storage destination corresponding to the extension number of the requesting source. The IP terminal which receives the IP address re-transmits the connection request toward the IP address. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:提供一个电话系统,通过该电话系统,用户登录系统而不管地点。 解决方案:除了通过在电话系统中进行交换形成的数据库对应于IP地址的节点信息DB之外,作为通过使IP终端的分机号码形成的数据库的另一个节点用户信息DB 对应于在规定的连接目的地的交换机的标识符被存储在每个交换中。 然后,当从IP终端向交换机发送连接请求时,交换机向请求源的IP终端通知与请求源的分机号相对应的存储目的地的交换机的IP地址。 接收IP地址的IP终端向IP地址重新发送连接请求。 版权所有(C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a telephone system constituted so that additional service concerning call termination of automatic incoming call distribution service and incoming call transfer service, etc. is efficiently attained without pressing memory capacity of each main unit.
      SOLUTION: An extension group G1 is preliminarily associated with main units BT1, BT2 on a dedicated line 1, a management table 111 representing correspondence relation between a plurality of telephone terminals and their login states is stored in the extension group G1 only in the main unit BT1, the main unit BT2 monitors a login state of a telephone terminal to be stored in the self-unit BT2 and informs the main unit BT1 of login state information of a logged in telephone terminal.
