Abstract

PURPOSE:To save the handling time of a caller by disconnecting a call once automatically when definite time elapses before the reply of a callee for the call from the caller, and after previously designated time elapses, originating the call automatically to the same extension. CONSTITUTION:A central control device 8 having detected dial information sent by a subscriber 2 stores the detected dial information in a storage device 7, and calls the subscriber 3 by a main switch 1 through a subscriber's circuit 3a. When there is no reply of the subscriber 3, a non-reply count timer 4 is operated so as to count. In the case that it counts out before the reply of the subscriber 3, the main switch 1 sends an alarm sound to the subscriber 2, and disconnects the call to the subscriber 3. In the case that a reorigination waiting count timer 5 counts out while there is no operation of the subscriber 2, the dial information stored in the storage device 7 is read out by the central control device 8, and the same operation is repeated by calling the subscriber 3 again by the main switch 1 through the subscriber's circuit 3a.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic dialing system using a private branch exchange.

[Conventional technology]

The traditional calling method detects that the caller is off-hook and then calls the recipient by dialing the extension number.
If the recipient did not respond, the caller would go on-hook and repeat the same operation.

[Invention or problem to be solved]

In the conventional calling method described above, if the recipient does not respond, the caller must go on-hook once and repeat the same operation when calling again, which is very time-consuming.

An object of the present invention is to provide an automatic calling system that solves the above problems.

[Means to solve the problem]

In order to achieve the above object, in the automatic dialing system according to the present invention, in an automatic exchange equipped with a timer, if a certain period of time passes without a response from the caller to a call from the caller, the automatic call The call will be disconnected once, and after a pre-specified time has elapsed, the call will be automatically dialed again to the same extension.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a flowchart showing one embodiment of the main operating procedures of the present invention, and FIG. 2 is a plot diagram showing an example of the main components of a private branch exchange that realizes FIG.

In FIG. 2, the private branch exchange includes a main switch 1, an extension telephone on the calling side (hereinafter referred to as subscriber) 2, and a subscriber circuit 2a.
, an extension telephone on the receiving side (hereinafter referred to as subscriber) 3, a subscriber circuit 3a, a storage device 7 for storing caller's dial information, a non-response count timer 4 that counts when the subscriber 3 does not respond, An alarm sound sending device 6 that sends out an alarm to notify the caller that the caller will be disconnected when the response count timer 4 times out, and an elapsed time for disconnecting subscribers 2 and 3 after sending the alarm and waiting for re-calling. It has a re-transmission wait count timer 5 for counting, and a central controller 8 for controlling them.

First, subscriber 2 receives the calling number via extension 2a,
A call from subscriber 2 is detected (operation procedure ■) and a call signal is output. Subscriber 2 receiving the calling signal sends out dial information. The central control unit 8 detects the dial information sent by the subscriber 2 (operating procedure ■), stores the detected dial information in the storage device 7 (operating procedure ■), and sends the detected dial information to the main switch 1 via the subscriber circuit 3a. Call subscriber 3 (operation procedure ■).

If there is no response from the subscriber 3 (operation procedure ■), the non-response count timer 4 is activated and counted (operation procedure ■).

If time alarm 1~ occurs without a response from subscriber 3 (operation procedure ■), main switch 1 sends out an alarm sound from alarm sending device 6 to subscriber 2 (operation procedure ■
) Notify that the call has timed out and disconnect the call from subscriber 3 (operation procedure ■), subscriber 2 remains off-hook and waits for a re-call, and activates counters 1 to 5 at the time of re-call. Start counting (operating procedure ■).

When the re-call waiting count timer 5 times out without any operation by the subscriber 2 (operation procedure ■), the central controller 8 reads out the dial information stored in the storage device 7, and the main switch 1 reads out the dial information from the subscriber circuit 3a. Call subscriber 3 again via (operation procedure ■) and repeat the same operation.

If there is a response while the subscriber 3 is calling (operation procedure ①), or if there is some operation by the subscriber 3 while waiting for a re-call, the automatic call is canceled.

〔Effect of the invention〕

As explained above, the present invention has the effect of saving the caller's time and effort since the dialing operation can be omitted when making a second call.
