BACKGROUND OF THE INVENTION
The present invention relates to a PBX (private branch exchange). Further, the present invention relates to a so-called call waiting service, which is a function that notifies the fact that an incoming call is received from another phone and switches the call partner when the called party hooks.
[0002]
[Prior art]
The call waiting service in PBX has the following functions. That is, if a call waiting service subscriber (hereinafter referred to as a call waiting subscriber) receives a call from the second caller to the call waiting subscriber while the call is being made with the first caller, Receive notification that there is an incoming call. When the call waiting subscriber performs a hooking operation on this notification, the PBX switches the line to the second caller after holding the line of the first caller. When the hooking operation is performed again after the call with the second caller ends, the line is switched to the line with the first caller.
[0003]
In this way, even if the call waiting subscriber is already in a call, it can respond to an incoming call from the other party. However, on the other hand, the call waiting subscriber can make a call with the second caller while keeping the first caller on standby. In the meantime, there is a problem that the call waiting subscriber forgets to be on standby and the handset is on-hook after the call with the second caller ends.
[0004]
In order to prevent this problem, Japanese Utility Model Laid-Open No. 4-94841 discloses a hooking operation detection means, a means for performing a notification operation after a predetermined time has elapsed since the first hooking operation, and the operation of the notification means being stopped by detecting the hooking operation again There has been proposed a telephone (conventional example 1) that, when a hooking process is performed during a call, drives a warning sound and an LED lamp after a predetermined time elapses to notify the caller that it is a call waiting service.
[0005]
The telephone user of Conventional Example 1 starts a call with the second caller by performing a hooking operation after detecting a catch tone signal sound from the second caller during a call with the first caller. After a certain period of time has elapsed since the hooking operation, the notification operation means notifies that the call waiting service is being received, and if the hooking operation is performed again, the notification operation is stopped.
[0006]
According to Conventional Example 1, there is an advantage that even if the call with the second caller takes a long time, the call waiting subscriber does not forget to call with the first caller.
[0007]
[Problems to be solved by the invention]
However, the notification operation is not stopped unless the call with the second caller is interrupted, and the telephone user feels troublesome. Further, when viewed from the first caller, there is a problem that the receiver must be kept off-hook until the call between the call waiting subscriber and the second caller is terminated.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
The PBX of the present invention includes a timer unit, a control unit, and a telephone number registration unit therein, registers the telephone number of the first caller in the telephone number registration unit, and joins the call waiting after the call with the second caller ends. When the party performs a hooking operation, the control unit reads out and dials the telephone number of the first caller from the telephone number registration unit.
[0014]
With such a configuration of the present invention, the first caller can stand by in an on-hook state after a predetermined time has elapsed, and the call with the first caller is hooked after the call with the second caller ends. It can be resumed by a simple operation, and the call waiting user does not need to input the phone number again.
[0015]
The configuration of the PBX 100 according to the first embodiment of the present invention will be described with reference to the functional block diagram of FIG. The PBX 100 includes a timer unit 110 that monitors the hold time of the first caller 300, a phone number registration unit 120 that registers the phone number of the first caller 300, a control function 130 that controls the PBX 100, and a function that the conventional PBX has Is provided with a conventional function unit 140. In addition, the call waiting subscriber is indicated by 200, the first caller is indicated by 300, and the second caller is indicated by 400.
[0016]
Next, the operation of the PBX 100 will be described with reference to the flowchart of FIG.
[0017]
During a call between the call waiting subscriber 200 and the first caller 300, there is an incoming call from the second caller 400 by the call waiting service (S21).
[0018]
When the call waiting subscriber 200 performs a hooking operation, the PBX 100 with an automatic redial function puts the line with the first caller 300 on hold and switches to the line with the second caller 400 (S22). At this time, the control unit 130 detects that the line has been switched to the second caller 400 and sends a signal to the timer unit 110. The timer unit 110 receives the signal from the control unit 130 and starts counting using this as the holding time of the first caller 300.
[0019]
When the timer unit 110 counts for one minute or more, the timer unit 110 sends a signal to the control unit 130 (S23).
[0020]
When the control unit 130 receives the signal from the timer unit 110, the control unit 130 asks the first caller 300 that "the telephone is re-called after the call is completed, so the telephone number is registered by pressing the push button, and then the receiver is put on standby. Please notify me "(S24).
[0021]
When the first caller 300 presses the push button, the telephone number of the first caller is registered in the telephone number registration unit 120 by the push button. The first caller 300 waits for an incoming call from the call waiting subscriber 200 in an on-hook state after registration of the telephone number (S25).
[0022]
After the first caller 300 registers the phone number in the phone number registration unit 120, when the call between the call waiting subscriber 200 and the second caller 400 ends, the call waiting subscriber performs a hooking operation (S26), thereby controlling the call. The unit 130 reads the telephone number of the first caller 300 from the telephone number registration unit 120, and redials the first caller 300 from the conventional function unit 140 (S27).
[0023]
When the first caller 300 receives an incoming call from the PBX 100 and off-hooks the handset, a call with the call waiting subscriber 200 is started (S28).
[0024]
When the call between the call waiting subscriber 200 and the second caller 400 ends when the hold time of the first caller 300 is within a predetermined time or during telephone number registration work, the call waiting subscriber performs a hooking operation to control the call. The unit 130 connects the lines between the call waiting subscriber 200 and the first caller 300, and the call is resumed through the conventional function unit 140 (S29).
[0025]
When call waiting subscriber 200 ends the call, the telephone number of first caller 300 registered in telephone number registration unit 120 is deleted. When the first caller 300 disconnects the line without registering the telephone number in the telephone number registration unit 120, this function does not operate.
[0026]
Next, a second embodiment of the present invention will be described. Since the configuration of the second embodiment is the same as that of the first embodiment, description regarding the configuration is omitted, and only the operation is described.
[0027]
During a call between the call waiting subscriber 200 and the first caller 300, there is an incoming call from the second caller 400 by the call waiting service (S31).
[0028]
When the call waiting subscriber 200 performs a hooking operation, the PBX 100 puts the line with the first caller 300 on hold and switches to the line with the second caller 400 (S32). At this time, the control unit 130 detects that the line has been switched to the second caller 400 and sends a signal to the timer unit 110. The timer unit 110 receives the signal from the control unit 130 and starts counting using this as the holding time of the first caller 300.
[0029]
When the timer unit 110 counts for one minute or more, the timer unit 110 sends a signal to the control unit 130 (S33).
[0030]
When receiving the signal from the timer unit 110, the control unit 130 recognizes that the telephone line is from the first calling party 300, and registers the telephone number of the first calling party 300 in the telephone number registration unit 120 (S34). Then, the first caller 300 is notified that "I will call again after the call ends, so please put the handset on standby." First caller 300 waits for an incoming call from call waiting subscriber 200 in an on-hook state (S35).
[0031]
