Conventionally, one call management number (single call management number) is assigned to one terminal located on one physical wiring. ) Only managed calls. However, when a multiline telephone terminal generates a plurality of calls, such as when a multiline telephone terminal capable of handling a plurality of calls on one physical wiring is connected as an extension terminal, a plurality of call management numbers are generated. The conventional method of managing only one call with one call management number (single call management number) for one terminal cannot handle a plurality of calls that can be used in a multiline telephone terminal.

  Therefore, as a call management method when a terminal that handles a plurality of calls is connected, the number of calls, call management number, and service status information that exist in each of the low function terminals that handle only one call in the exchange are managed as a plurality of calls. A technique for managing a plurality of calls by storing them in a memory and providing an exchange function corresponding to the plurality of calls to a low function terminal is disclosed (for example, Patent Document 1).

  However, in the technique of Patent Document 1, in addition to the call management number, the number of calls existing in the low function terminal and the call service status must be recorded, and it is necessary to prepare a large amount of information storage means (memory). Therefore, there is a problem that the state transition of the telephone control device becomes complicated and takes time to develop.
