FIG. 2 shows a subscriber number system in the storage and exchange apparatus of the present invention. The subscriber number in the storage exchange comprises a number indicating the exchange in which the subscriber is accommodated and a subscriber number, for example, an exchange number and an extension number.

The exchange number and extension number will be described below as an example.

FIG. 3 is a network data management table for retrieving the leased line dial information specified when actually making a call from the storage and exchange device to the destination subscriber terminal from the source exchange number and the destination exchange number. .

First, a description will be given based on FIG.

(1) In a network where exchanges are installed at multiple business establishments and each exchange is connected by a dedicated line (dedicated line), when making a call from each business establishment to another establishment via the dedicated line There are cases where the numbering plan for the specified leased line dial information is unified throughout the network, and cases where it is different for each exchange.

FIG. 3 shows that even if the exchanges differ depending on the exchange, if the store-and-exchange device is installed in one business office, the store-and-exchange device can be used so that the user can use the service of the store-and-exchange device according to the number plan when making a call. It is a network data management table for comprehensively managing the numbering plan for each exchange in the device.

(2) The following table shows an example of inputting the sender subscriber number and the destination subscriber number.

However, when is from the subscriber terminal 1a to the subscriber terminal 1b, similarly, is from 2a to 1b and is from 3a to 1b.
2a to 2b, and 2a to 3b.

(3) An example of searching for the sender and destination subscriber numbers (mailbox numbers for storing messages) from the input sender number and the input destination number will be described.

The exchange number is omitted from the input caller number. Since the subscriber terminal 1a is connected to the same exchange 1 as the storage / exchange device 4, it means that the storage / exchange device 4 is being used from an extension, and only the extension number is used as in the case of making a call between extension lines. Available.

The storage exchange device 4 searches the network data management table shown in FIG. If the originating exchange number is omitted, the number 9 with the storage / exchange device accommodation display *
00 is used as the source exchange number, and 900-3001 is managed as the subscriber number of the caller.

Also, the dedicated line dial information of the input destination number is omitted. Both the subscriber terminal 1a and the subscriber terminal 1b have the same extension of the exchange 1, and only the extension number needs to be designated as in the case of making a direct call. The storage exchange device 4 searches the network data management table shown in FIG. Since the originating exchange number is 900 and there is no leased line dial number, you can search for the destination exchange number as 900,
The destination subscriber number is found to be 900-5001 and the message is stored in mailbox 900-5001. Since the exchange number is also input to the input caller number, it can be seen that the caller is a terminal subscriber connected to an exchange different from the store-and-exchange device.
10-4001 is managed as the sender's subscriber number.

The dedicated line dial information of the input destination number is 900. From the network data management table in FIG. 3, since the source exchange number is 910 and the leased line dial information is 900, it is possible to retrieve that the destination exchange number is 900, and the destination subscriber number is 900-5001. to manage.

Since the exchange number is also input to the input caller number, it can be seen that the caller is a terminal subscriber connected to an exchange different from the store and exchange apparatus 4, and 920-5
001 is managed as the subscriber number of the sender.

The dedicated line dial information of the input destination number is 90. Third
From the network data management table in the figure, since the source exchange number is 920 and the leased line dial information is 90, it can be retrieved that the destination exchange number is 900,
The destination subscriber number is managed as 900-5001.

Here, although the same destinations are used in (1) to (3), when each sender specifies the destination based on the number system of the existing network, the input destination numbers are different. However, even if the input destination numbers are different, the storage and exchange device 4 can manage as the same subscriber 900-5001 by searching the network data management table in the device.

Since the exchange number is also input to the input caller number, it can be known that the caller is a subscriber terminal connected to an exchange different from the storage and exchange apparatus 4, and 910-4
10 is managed as the subscriber number of the sender.

The leased line dial information for the submission destination number is omitted.
When a caller sends a message to a destination subscriber terminal connected to the same exchange as himself, the caller can specify the destination only by the extension number as in the case of making a direct call. From the network data management table of FIG. 3, since the source exchange number is 910 and there is no leased line dial information, it is possible to retrieve that the destination exchange number is 910, and the destination subscriber number is managed as 910-5001.

Since the exchange number is also input to the input caller number, it can be seen that the caller is a terminal subscriber connected to an exchange different from the storage and switching apparatus 4, and 910-4
001 is managed as the subscriber number of the sender.

The dedicated line dial information of the input destination number is 90. Third
From the network data management table in the figure, since the source exchange number is 910 and the leased line dial information is 90, it is possible to retrieve that the destination exchange number is 920,
The destination subscriber number is managed as 920-5001.

Here, the input destination numbers of and are the same, but the actual subscriber terminals are different. In the storage exchange device 4, the destination subscriber number is 900-5001 by searching the network data management table in the device.
And 910-5001, and 900-5001 and 920-
It can be identified that it is 5001.

FIG. 4 shows an example of data stored in the storage device.

FIG. 5 is a block diagram of an embodiment of the present invention. In FIG. 5, 1 is an exchange, 1a to 1n are subscriber terminals, 4
Is a storage / exchange device, 4a is a line controller, 4b is a central processing unit, 4c is a seed storage device, and 4d is a disk device. The caller calls the storage and exchange device 4, specifies the destination, and registers the message. The storage exchange device 4 temporarily stores the received message in the disk device 4d and then sends it to the destination subscriber terminals 1a to 1n. Next, an embodiment of the present invention will be described with reference to the flowcharts of FIGS.

First, the transmission and accumulation of messages will be described with reference to FIG.

As shown in FIG. 1, the storage and exchange device and the subscriber terminal 1a
(Extension number = 3001), subscriber terminal 1b (extension number = 3001)
5001) is the office A of the exchange 1 (exchange number = 9)
00) and the subscriber terminal 2a (extension number = 400
1) and the subscriber terminal 2b (extension number = 5001) are both housed in the office B of the exchange 2 (exchange number = 910). Also, the subscriber terminal 3a (extension number = 5001)
Is housed in the business office C of the exchange 3 (exchange number = 920).

When the caller sends a message, first, the storage / exchange device call number is dialed to call the storage / exchange device 4. Next, the subscriber number of the sender, for example, 3001 for the subscriber terminal 1a and 910-4 for the subscriber terminal 2a.
Input 001. At this time, the store-and-exchange device checks whether or not the exchange number is added to the telephone number provided as the subscriber number by comparing it with the source exchange number in the network data management table.
If it is not added, the source leased line number (900) for which the storage / exchange device accommodation display is displayed is extracted, and at the same time, the source subscriber number is stored and managed by adding the exchange number. If so, the originating exchange number (910) is extracted from the entered subscriber number. Next, the caller uses the telephone number of the destination subscriber terminal based on the numbering system of the network, for example, 900-3001 (dedicated line dial information + extension number) if the subscriber terminal 2a is addressed to the subscriber terminal 1a. 5 for subscriber terminal 2b
Specify only with 001 (extension number).

At this time, the storage exchange apparatus checks whether or not the leased line dial information is added to the telephone number input as the destination, and if it is added, the destination exchange number is determined by the network data management table shown in FIG. Search for the subscriber number of the destination. After that, the caller records a message and ends the series of operations. In the storage exchange device, the recorded message from the sender is stored in the mailbox of the destination subscriber as shown in FIG.

Next, referring to FIG. 7, reception of a message by an operation from the subscriber side will be described.

From the subscriber terminal, enter the subscriber number to retrieve the message addressed to the subscriber terminal.

In the message storage device, when the subscriber number is received, it is determined whether or not the exchange number is added to the input number from the subscriber, and if not, the exchange number is added to the sender number, Compare with subscriber number in stored message. If there is a corresponding message, it is extracted and played.

Next, with reference to FIG. 8, automatic transmission will be described with reference to a flow chart at the time of automatic transmission of a message.

Using the management table shown in FIG. 3, the leased line dial information designated when the destination subscriber terminal is called is searched. First, the network data management table is searched for the leased line number “900” of the exchange that accommodates the storage and exchange device, and then the leased line number added to the destination subscriber number and the destination of the destination is determined from the network data management table. Search for a leased line number to dial when calling a subscriber terminal.
For example, when the exchange number of the destination subscriber number is "910", the network data management table is searched to find out that the leased line number to be dialed when actually transmitting is "910", and the leased line is searched. Dial the dialing information "910" and the extension number. When the destination exchange number is "900", the network data management table is searched to find that the leased line dial information to be dialed when actually transmitting is "none", and only the extension number is used as dial information. Dial.
By calling the destination subscriber terminal using the dial information actually transmitted thus searched, a message is transmitted to the subscriber terminal designated by the caller.

(Effect of the Invention) According to the present invention, even when a store-and-forward device is newly introduced, the telephone number system of the existing network can be used as it is as the subscriber number system, so that the operational complexity is eliminated. You can easily use the storage exchange device.
