What is done is summarized. ISD
When the central control unit detects a telephone call made using the N circuit, it stores user / user information in the user / user information storage unit, and the central control unit uses this as a search key to receive an extension from the destination storage unit. The number is detected, the destination is determined, the extension control unit is controlled, and the extension number is connected to the designated extension number.

[0006]

According to the present invention, with the above configuration, the central control unit fetches the ISDN user / user information into the user / user information storage unit when there is a call from the central office line. Next, the central control unit searches the destination extension number registered in the destination storage unit using the ISDN user / user information as a search key, determines the destination extension number requested by the caller, and rings the extension telephone. .. In this way, the destination extension number is determined by using the information other than the calling number as the search key by using the user / user information. Therefore, even if the same number is used, different extension numbers are used if the sender's gender, department, etc. are different. It is possible to make an incoming call to the terminal and meet the request of the sender accurately.
