JPS62277840A - Recalling device for unreplied extension - Google Patents

Abstract

PURPOSE:To dial a recall number immediately after a call is once generated by a called extension and the call is finished by registering an extension subscriber recall number at the time of unreplying when an extension subscriber calls the called extension subscriber and receives no reply. CONSTITUTION:A main storage device 9 is provided with an unreply extension recall information registered by a an extension subscriber and a storage circuit 9b storing recall presence information for the unreplied extension subscriber. If an extension subscriber 2 gives no reply due to its absence, an extension subscriber 1 dials an unreply extension recall number. The number is analyzed by a central controller 8, the information is written in the information storage circuit 9a and the recall presence information is written in the recall present information storage circuit 9b. The extension subscriber 2 is present and dials the extension subscriber 3, after the talking is finished, the recall number is dialed to talk between the extension subscribers 1 and 2.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an automatic private branch exchange system, and particularly to an unanswered extension recall system.

[Conventional technology]

Traditionally, this type of unanswered extension recall involves the calling extension dialing the number of the called extension, and if the called extension does not answer, it repeats until the called extension answers. , was doing the dialing.

[Problem that the invention seeks to solve]

In the conventional unanswered extension recall mentioned above, there is no way to confirm whether the called extension subscriber is present, and the extension subscriber dials the called extension subscriber number and the called extension subscriber In this case, the user must dial again and repeat the dialing process until the called extension subscriber answers, which is extremely inefficient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device that confirms whether a called extension subscriber is present and re-calls an unanswered extension.

[Means for solving problems]

The present invention includes a storage circuit for storing unresponsive extension recall information, a storage circuit for storing recall information of an unresponsive extension subscriber, and a memory circuit for storing recall information of an unresponsive extension subscriber, and a memory circuit for storing recall information of an unresponsive extension subscriber, and a memory circuit for storing recall information of an unanswered extension subscriber, and a memory circuit for storing recall information of an unanswered extension subscriber, and a memory circuit for storing recall information of an unanswered extension subscriber. The operation of the storage circuit is controlled based on the unresponsive extension recall number, and after the unresponsive extension,
When the called extension subscriber makes a call, the content stored in the storage circuit is immediately checked and verified, and the call is made between the extension subscriber who dialed the unresponsive extension recall number and the called extension subscriber as the other party. The unanswered extension recall device is characterized in that it has a central control device that outputs a signal necessary for starting.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

In this embodiment, the main storage device 9 shown in FIG. 1 includes a memory circuit 9a for storing unresponsive extension recall information registered by an extension subscriber, and a memory circuit 9a for storing recall information for unresponsive extension subscribers. This is realized by providing a memory circuit 9b that performs the following operations.

FIG. 2 shows an unresponsive extension recall information storage circuit 9a provided in the main storage device 9, which includes information on the calling extension subscriber who has set the unresponsive extension recall and unresponsive extension recall information. The section RCOO, RcOI, . . . RCn that stores called extension subscriber information set with

FIG. 3 shows a storage circuit 9b provided in the main storage device 9, in which parts 5NOO and 5NO store information on whether or not a non-responsive extension subscriber is recalled corresponding to an extension subscriber number.
I, -3Nn is shown.

In FIG. 1, when extension subscriber 1 dials extension subscriber 2, the resubscriber is connected via switch 7 by known means, and the calling extension subscriber 1 receives a ring tone and the called extension subscriber A ringing signal is sent to each person 2.

At this time, if the extension subscriber 2 is absent or does not respond, the extension subscriber 1 dials the unresponsive extension recall number. The dialed unanswered extension recall number is analyzed by the central controller 8 via the line circuit 4, and as a result is stored in the unanswered extension recall information storage circuit 9a provided in the main storage 9 of the calling extension subscriber. Write information and unresponsive extension subscriber information.

Based on the analysis result, the central control device 8 stores the non-responsive extension subscriber recall information storage circuit 9b, which is also provided in the main storage device 9, at the position corresponding to the extension subscriber 2. Write the information with recall.

Thereafter, extension subscriber 2 becomes present and dials extension subscriber 3, and by known means, both subscribers are connected via switch 7 and the two parties enter into a conversation.

Thereafter, the call between both subscribers ends, and extension subscriber 2 returns the handset to end the call. At this time, central control unit 8 executes call termination processing for extension subscriber 2 by known means. At the same time, whether or not the unresponsive extension subscriber is recalled is checked in the portion corresponding to the extension subscriber 2 of the unresponsive extension subscriber recall information storage circuit 9a provided in the main storage device 9.

Since there is an unresponsive extension subscriber recall, the central control device 8 checks the unresponsive extension recall information storage circuit 9b provided in the main storage device 9, and stores the unresponsive extension subscriber information in the unresponsive extension subscriber information position. Search for extension subscriber 2 and find extension subscriber 1 stored in the corresponding calling extension subscriber position.
Search for.

Then, a ringing signal is sent to the extension subscriber 1 by a known means. When the extension subscriber 1 answers, a ringing tone is sent to the extension subscriber 2 by a known means. Since extension subscriber 2 is present, extension subscriber 2 responds, and extension subscriber 1 then makes a call with extension subscriber 2.

〔Effect of the invention〕

As explained above, when an extension subscriber calls a called extension subscriber and the called extension does not respond due to absence or the like, the called extension subscriber can be called again by registering the recall number of the unanswered extension subscriber. Once the calling extension is present and once the calling operation is completed and the call is completed, the extension subscriber who dialed the unanswered extension recall number is automatically called, and it is confirmed that the called extension subscriber is available to answer. Notification calls can be made, and the practical effect is extremely large.
