Abstract

PURPOSE:To recognize a caller number even without tentative interruption of communication for a busy terminal equipment by storing the caller number when a busy extension terminal equipment receives a call and informing the number to the extension terminal equipment. CONSTITUTION:When a call comes from an extension terminal equipment 10 to an extension terminal equipment 8 while an extension terminal equipment 9 and the extension terminal equipment 8 are in talking, an exchange control section 2 confirms it that the extension terminal equipment 8 is busy depending on the call connection information and a data stored in a memory 2a, sends a busy tone to the extension terminal equipment 10 via a channel 3 and stores a data representing the presence of a call from the extension terminal equipment 10 to the extension terminal equipment 8 and the busy extension terminal equipment 8 into the memory 2a. Then the exchange control section 2 sends a display data of, e.g., 'a call from extension '202', busy' to the extension terminal equipment 8 and displays it onto the extension terminal equipment 8 while the extension terminal equipment 8 is busy.

得ることができる。On the other hand, if the extension terminal 8 is a terminal that is not equipped with a display, data control, etc., the exchange control unit 2 will display, for example, "A call has arrived from extension 202, but the call is busy" after the extension terminal 8 has finished communicating. was. ” is sent to the extension terminal 8 via the communication path 3 (procedure D) 3. Therefore, according to the second embodiment, the user of the extension terminal 8 can send the voice signal “” to the extension terminal 8 via the communication path 3. It is possible to obtain incoming call information from the extension terminal 10, and it is not limited to incoming calls from the extension terminal 10.
Even when a network such as JSDN that notifies the caller's number is connected as an outside line, it is possible to obtain 1'a notification of incoming calls from the outside line.
