である。(Example) Conventional technology Conventionally, some automatic exchange machines have been equipped with call waiting and waiting functions. The call waiting function is used when a first terminal (called extension) is currently talking with a second terminal.
When the third terminal (calling extension) receives a call, the called extension hears the call waiting tone.
Notifies you of an incoming call from the calling extension, while letting the calling extension hear the ring tone, and then, if it detects an operation such as hooking on the called extension, puts the second terminal currently in communication with the called extension on hold. This service allows a call to be made between the called extension and the calling extension.

者）に不快感を与えるという問題がある。(c) Problems to be Solved by the Invention The conventional call waiting method described above allows incoming calls to be interrupted unconditionally regardless of the importance or urgency of the incoming call. Therefore, the called extension is frequently interrupted. In this case, there was a problem that the operator of the called extension had to perform more operations, and the second terminal was often put on hold due to the call waiting process, making it difficult for the other party (the operator of the second terminal) to perform the call. There is a problem with causing discomfort.
本発明は上記問題に鑑み為されたものであり、割り込み

る。(2) Means for Solving the Problems The present invention is provided with one storage stage for storing the number of incoming calls from a third terminal that has arrived at a first terminal during a call with a second terminal, and stores the number of calls in the storage means. This is a call waiting method whose purpose is to set the call from the third terminal to a call waiting state when the number of incoming calls received is equal to or greater than a predetermined value.

When the extension number of the extension telephone 21 is dialed from the telephone 2k, the control device 3 checks the stored contents of the extension telephone 21 in the incoming call information storage area. The control device 3 stores the contents stored in the incoming call information storage area and the calling extension 2.
If they match, the extension telephone 2k plays a ring tone, the extension telephone 21 hears an interrupt tone, and the call is placed in an interrupt state. Waiting) (status!!3).

できる。Further, when the extension number of extension telephone 21 is dialed from extension telephone 2 (not shown) in state 2, control device 3 checks the stored contents of extension telephone 21 in the incoming call information storage area. The control device 3 stores an extension telephone 21 in the incoming call information storage area.
! If not stored, a busy tone is heard on the extension telephone 2N. At this time, since the extension telephone 2k is already stored in the position corresponding to the extension telephone 21 in the incoming call information storage area, the extension telephone 2R. In addition, in the above embodiment, the incoming call information storage area for each called extension is erased after a predetermined time by using a timer provided for each called extension. The incoming call information storage area may be deleted after a predetermined period of time by using a timer provided for each calling extension, or at the time when the call with the first terminal ends or when there is an incoming call after the end of the call. You can also delete one. Thereby, information on a plurality of extensions can be stored in the incoming call information storage area. For example, in the embodiment described in FIGS. 1 to 3, the extension telephone 2k and the extension telephone 2! You can memorize not only extension K but also extension! It is also possible to set a call waiting state when the second call arrives.

ていき、その個数を計数することなどが考えられる。Furthermore, in the above-described embodiment, a call from a calling extension is call-waiting based on whether or not the call is stored in the incoming call information storage area, that is, whether it is the second incoming call from the same calling extension. However, it may be determined whether or not to set call waiting based on whether or not the call is received for the third time or more. In this case, how to use the incoming call information storage area may be determined as appropriate. For example, the number of incoming calls may be stored in relation to the calling extension, or if the incoming call information storage area is configured to store multiple extensions as described above, the calling extensions may be stored sequentially and the number of calls may be stored in association with the calling extension. One possibility is to count the

To choose whether to ring the same extension again,
Interruptions to an extension telephone during a call are limited to important matters, and interruptions during a call are kept to a necessary minimum. Therefore,
This has the effect of reducing the number of operations required on the called extension and reducing the discomfort felt by the other party on hold.
