PURPOSE:To avoid inconvenience that it is not clear who is an opposite party till a line is connected to an extension user in reply with a call and talking is made with the opposite party actually by utilizing an ID code assigned to each extension user so as to implement line connection processing. CONSTITUTION:When an extension user recognizing it that the user is called enters its own ID code from an optional extension terminal equipment, a call line information notice function 304 is operated and the information of a trunk line or an extension making a call with the relevant ID code is extracted from the information stored in the call line information storage section to the extension terminal equipment receiving the ID code and the content of the extracted information is informed by a proper means such as a voice or a character display to the extension terminal equipment receiving the ID code. Thus, the information of the caller is acquired before the line is connected and the inconvenience that it is not clear who is an opposite party till a line is connected, talking is made with the opposite party actually is avoided. |
