Abstract

PURPOSE:To simplify the use of a voice storage device. CONSTITUTION:An exchange 2 is equipped with a table registering the identification code of a subscriber to be called, information showing whether a telephone number always used by this subscriber is existent or not, and the number of stored messages to the relevant subscriber while making them correspondent. For example, when the subscriber to be called at a telephone set 4 is absent while referring to the table in the case of originating a call from a telephone set 3 to the telephone set 4, such a state is reported to the calling subscriber of the telephone set 3 and on the other hand, when the subscriber to be called inputs the own identification code by a card reader 6, while referring to the table, a voice storage device 1 reports the presence/absence of messages to the relevant subscriber to be called to the subscriber to be called at the telephone set 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for an exchange equipped with a voice storage device.

[0002]

2. Description of the Related Art As shown in a block diagram of a conventional example in FIG. 2, in an exchange (hereinafter, EX) 2 equipped with a voice storage device (hereinafter, VRE) 1, for example, a telephone (hereinafter, T
If a subscriber of EL) 3 calls a subscriber of TEL4,
In response to the calling operation of TEL3 by the calling subscriber, EX2 makes a switching connection and sends a calling signal to TEL4 of the called subscriber. If the called subscriber of TEL4 is not present, the calling subscriber joins. The person judges whether or not to use the VRE 1, and when using this, the TEL 3 dials the designated number.

Then, EX2 connects the calling subscriber's TEL3 to VRE1, and VRE1 sends a guide message in response to this, so that the calling subscriber uses TEL3 to send the called subscriber's mailbox. By performing an operation including designation of a number and sending a voice message, this is stored in VRE1.

When the called subscriber retrieves a message addressed to himself from VRE1, TEL4 requests EX2 to connect to VRE1 by dialing a designated number.
After connection, perform the operation according to the guide message from VRE1 and check whether the message addressed to self is stored. If stored, perform the specific operation and request VRE1 to send the message addressed to self. It is supposed to do.

[0005]

However, in the prior art, in order to use VRE1, it is first necessary to confirm the absence of the called subscriber, and further various operations are required to confirm the presence / absence of a stored message and retrieve it. These are troublesome and have a drawback that VRE1 cannot be used easily. Therefore, an object of the present invention is to provide a voice store-and-replace control method that can easily use VRE1.

[0006]

In order to achieve the above-mentioned object, the present invention, in the above-mentioned exchange control system, determines whether the identification code of the called subscriber and the telephone number that this subscriber is using are present. A table in which information and the number of accumulated messages to the subscriber are registered in correspondence, code input means for inputting the identification code of the called subscriber, and a call operation from the calling subscriber to the called subscriber is performed. Means for notifying the calling subscriber of this fact when the called subscriber is absent by referring to the table, and referring to the table according to the input of the identification code to the code input means, and whether or not there is a stored message for the called subscriber Is provided.

[0007]

[Operation] Therefore, by the operation of making a call to the called subscriber,
The absence of the called party is immediately notified, and the called party is immediately notified of the presence or absence of a stored message addressed to itself by only inputting the identification code.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the block diagram of FIG. In the figure, in addition to the configuration shown in FIG. 2, card readers (hereinafter, CRDs) 5 and 6 as code input means are attached to the TELs 3 and 4 of each subscriber, thereby identifying each subscriber. The iD card on which the code is recorded is read and the result is sent to EX2.

Further, the EX2 includes a processor (hereinafter, CPU) having a memory, which controls the exchanging operation of the EX2, and the table of the following table using a specific area is stored in the memory. Each data in the table is updated according to the operations of the subscribers 3 and 4 and the operation of the VRE 1.

[0010]

[Table 1]

That is, in this table, the identification code for each subscriber is registered as the subscriber iD, and information indicating whether or not each subscriber exists in the regular telephone number,
Also, the number of accumulated messages for each subscriber is registered in correspondence with each other, and the presence / absence information is the T
While the number of messages is updated by the specific operation of EL3 and EL4, the number of messages is updated according to the operation of VRE1.

Here, for example, when a subscriber of TEL3 makes a call to TEL4, the CPU of EX2 refers to the table in response to the dial transmission to TEL4, and whether or not the called subscriber exists at this regular telephone number. If it is absent, the calling subscriber of TEL3 is immediately notified by sending a specific signal to that effect.

In response to this, the calling subscriber of TEL3 receives VR.
When E1 is used, EX2 connects to VRE1 by dialing a specific number by TEL3, whereby messages are accumulated and the number of messages accumulated for the called subscriber is increased. Registered in the table.

Meanwhile, the called party of TEL3 returns and CR
Operate your own iD card by D6, or
When a similar operation is performed by another CRD at hand, the CPU of the EX2 accordingly refers to the table, determines the number of messages stored in the called subscriber, and the TEL4 attached to the CRD6 that has performed the input operation. Alternatively, after calling another TEL, the number of accumulated messages is notified by a specific signal, and if the accumulated number is not zero, inquiry is made as to whether or not to take out.

Therefore, the called subscriber can obtain the V
It becomes possible to listen to the message from RE1 freely.

[0016]

As is apparent from the above description, according to the present invention, the identification code of the called subscriber, information as to whether or not the subscriber has a regular telephone number, and a stored message for the subscriber. A table in which the numbers are registered in correspondence with each other and an input means for inputting the identification code of the called subscriber are provided, and the table is referred to according to the calling operation of the calling subscriber, and if the called subscriber is absent, While notifying the calling subscriber of this,
By referring to the table according to the input of the identification code to the code input means and notifying the called subscriber whether or not there is a stored message, the use of the voice storage device is simplified and the labor required for this is greatly increased. Since it can be omitted, a remarkable effect can be obtained in the exchange control including the voice storage device.
