JPH01278158A - Absence transfer system - Google Patents

Abstract

PURPOSE:To realize the accuracy of absence transfer by enabling plural transfer destinations to be designated and switching a designation destination based on a time when the designation of the time and the transfer destination is performed by an extension subscriber who sets the absence transfer. CONSTITUTION:The setting of the absence transfer is stored in a memory device 6 by the control of a central control unit 5 by dialing the time of the movement of the subscriber after off-hooking the extension subscriber 2 and following that, dialing the transfer destination after a designated time. Afterwards, an operation after the dialing of the time is repeated when the transfer destination is added. Next, in case of dialing the extension number of the extension subscriber 2 by the extension subscriber 1 at a call issuing side, all of the time and the extension numbers of the transfer destination are read out, and a dialed time is collated with read out time, and a call issuing extension subscriber 1 is connected to the extension subscriber 3 of a designated transfer destination, then, ringing is performed.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a call forwarding system in an exchange.

[Conventional technology]

Traditionally, call forwarding was set up by dialing a special number and then dialing the forwarding destination extension number, and if a call was received on the extension you were absent from, the call would be forwarded to the set forwarding destination extension. Ta.

[Problem to be solved by the invention]

In the conventional call forwarding method, only one forwarding destination can be specified, so if there are multiple destinations, the call cannot be accurately forwarded to the setter's location.

An object of the present invention is to provide a missed call forwarding system that solves the above problems.

[Means to solve the problem]

In order to achieve the above object, in the call forwarding system according to the present invention, an extension subscriber who sets up call forwarding in an automatic switchboard having a call forwarding function that allows calls to a forwarding destination specified in advance. When the time and destination are specified, multiple destinations can be specified, and the destination can be switched depending on the time.

〔Example〕

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

Figures 1 and 2 are flowcharts showing an embodiment of the main operating procedures of the present invention, in which Figure 1 shows the settings for call forwarding, and Figure 2 shows an incoming call on extension 2 for which call forwarding is set. It shows the case.

FIG. 3 is a block diagram showing an example of the main components of an in-tank exchange device that realizes FIGS. 1 and 2. FIG.

In FIG. 3, the in-tank exchange is a main switch 4, an extension subscriber 1 on the calling side for realizing FIG. 2, and a subscriber circuit 1a.
, the extension subscriber 2 who sets up call forwarding to realize FIGS. 1 and 2, the subscriber circuit 2a, and the forwarding destination extension subscriber 3.
, a subscriber circuit 3a, a storage device 6 for storing the forwarding destination extension number designated by the extension subscriber 2 and the designated time, a clock circuit 7 for confirming the designated time, and a central control unit (CPU) for controlling them. )5.

First, to set call forwarding, as shown in Figure 1, after off-footing subscriber 2 (operating procedure ■), dialing the time when the subscriber is moving (operating procedure ■), and then dialing the forwarding destination after the specified time. When dialing (operation procedure ■), the memory device r! is controlled by the central controller 5. 16 (operation procedure ■1. After that, if you have finished specifying the transfer destination, go on-hook (operation procedure ■), but if you want to add a transfer destination, dial the time (operation procedure ■) and the following. Repeat (operation procedure ■) Next, when extension subscriber 1 on the calling side dials the extension number of extension subscriber 2 who has set up call forwarding (operation procedure ■), call forwarding is performed from storage device 6. Read out all the times and forwarding destination extension numbers set in FIG. 1 corresponding to the set extension subscriber 2 (operation procedure ■),
The time at which the extension number of extension subscriber 2 was dialed by extension subscriber 1 and the time at which the extension number was read are verified (operation procedure ■).

Subsequently, the calling extension subscriber 1 is connected to the corresponding transfer destination extension subscriber 3 (operation procedure ■), and the extension subscriber 3 is ringed (operation procedure ■).

〔Effect of the invention〕

As explained above, the present invention has the advantage that a plurality of subscriber extensions can be designated as transfer destinations by setting the subscriber's transfer time.

Claims (1)

[Claims] (1) In an automatic switching system that has a call forwarding function that allows calls to a pre-specified forwarding destination, if the extension subscriber setting up call forwarding specifies the time and forwarding destination, multiple forwarding A missed call forwarding method that allows you to specify a destination and switches the specified destination depending on the time.
