Abstract

The present invention relates to a method for sharing an extension in a simple exchange, and in particular, by inputting a preset code and password through an extension terminal to receive a corresponding extension number, In regards to extension sharing method.

In the conventional simple switchboard, the station operation has a problem in terms of resource utilization because the station number is fixedly assigned to the port of the simple switch, and the station which occupies one port is not used because the frequency of use is low. For example, if a company employs a lot of salespeople who work outside of the company most of the time, allocating the extension to each employee will result in wasted resources because the capacity of the simple exchange will grow unnecessarily.

The present invention allows any user to designate one port of the simple switch as an extension number by login so that the corresponding port can answer the trunk line call and the extension call, and only the extension call is allowed for other stations. In addition, the station designated by the exchange group allows the station to be connected in response to a call from the trunk line, thereby efficiently utilizing the limited resources of the simple switchboard.

Description

Extension method for simple exchanges {Share Method of Extension in Simplicity Private Branch Exchange System}

The present invention relates to a method for sharing an extension in a simple exchange, and in particular, by inputting a preset code and password through an extension terminal to receive a corresponding extension number, In regards to extension sharing method.

In general, the simple exchange performs a function of connecting a call path so that an extension subscriber and a trunk line call can be made to an extension subscriber by receiving an extension subscriber. In the case of a trunk line call, there are many stations that can be connected to one trunk line, and each station is dedicated to one user. One station is connected to each port of the simple exchange, and one station number is fixed to each station.

The above-mentioned extension operation in the conventional simple switchboard has a problem in terms of resource utilization because the extension number is fixedly assigned to a port of the simple switchboard, and since the extension frequency occupies one port, which is often not used. For example, if a company employs a lot of salespeople who work outside of the company most of the time, allocating the extension to each employee will result in wasted resources because the capacity of the simple exchange will grow unnecessarily.

The present invention is to solve the problems as described above, the purpose is that by sharing a port of a simple switch, any user can designate one port as its own extension only when necessary, the efficiency of resource utilization To improve.

A feature of the present invention for solving the above object is a method for sharing an extension in a simple switch having a function of storing a received voice message, wherein each port for extension connection provided in the simple switch is provided. A physical port number determined in hardware, a logical extension number assigned to an extension terminal connected to the port, and a password assigned corresponding to the logical extension number to set the port to answer a call from a trunk line. Storing the data in a database; Set the function to store the physical port number of the port designated as a switch group that functions as an attendant to connect to the station in response to a call from the CO line, and to respond to the call of the CO line corresponding to the corresponding physical port number. Displaying the CO line response setting information in an activated state and storing the CO line response setting information in the database; Receiving a login code through a terminal connected to an extension of an extension number and receiving a password corresponding to the extension number to be designated as an extension for a CO line call response; Allocating an extension number corresponding to the received password to an extension of the arbitrary extension number; Determining whether a port of the extension number corresponding to the password is a port designated as the switch group; If the port of the extension number corresponding to the password is a port designated as an attendant group, the extension corresponding to the password is changed by changing and storing the CO line response setting information stored in the database in an inactive state corresponding to the extension number. Excluding the port of the number from the attendant group; When a call from a trunk line is transmitted to the extension number side corresponding to the password, the terminal connected to the extension number of the extension number receives a ring signal and responds.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a process of responding to a call from a trunk line by sharing an extension of a simple exchange according to the present invention.

An extension number and a password are assigned to each port provided in the simple exchange. The port number, the extension number, and the password corresponding to each port are stored in a database in the simple switch (S10). The port number is a physical port number determined by hardware as a number assigned to a port used to connect an extension, and the extension number is a logical extension that is variably assigned by a system operator as a number assigned to an extension terminal connected to the port. And a password is assigned corresponding to the logical extension in order to set the extension terminal connected to the port to answer the call from the trunk line.

Table 1 shown below is a table showing an example of the database.

Port number Extension number password 000 STA 100 1234 001 STA 101 2345 002 STA 102 3456 003 STA 103 5678 004 STA 104 7890

Table 1

On the other hand, some of the ports are selected as an Attendant group (a function as an Attendant that connects to an extension in response to a call from a trunk line), and the physical port number of the port belonging to the Attendant group is displayed in the database in the simple switch. Responding to a call from a CO line by storing it in a database by displaying the CO line response setting information that sets the function to respond to a CO line ring signal in correspondence with the corresponding physical port number as an active state (on state). Set the function (S11).

Table 2

When an extension subscriber inputs a login code and a password assigned thereto through a terminal connected to an extension (S12), an extension number corresponding to the input password is assigned to the extension (S13). It is available. For example, if a login code and a password 3456 are input through a terminal connected to an extension whose extension number is 100, the extension can be used by the extension number 102 corresponding to the password. Therefore, when there is a call specifying the extension number 102 from the trunk line, the call can be answered through the extension having the extension number 100.

If only the extension number 102 is activated by the login and the remaining extension number is not logged in, only the extension number 102 may respond to the CO line call and the remaining extension numbers may not respond to the CO line call.

Table 3 is a database table showing port numbers and whether CO line is available when only extension number 102 is activated.

Port number CO line call answer availability 000 X 001 X 002 O 003 X 004 X

Table 3

In addition, when logging in, the user is informed of the extension number, and in the case of the simple exchange providing the VMS, whether or not there is a stored voice message (S14). The method of notifying whether there is an extension number or a voice message can be displayed by text using the LCD, and when the user is off-hook, the message waiting tone is preferentially provided to the user that the message exists. There is also a way to tell.

If the extension number for which the call is requested from the trunk line is not logged in, the extension belonging to the attendant group responds to the call from the trunk line. In other words, if there is a call from the CO line with the extension number assigned to the extension subscriber without the extension subscriber logging in, the telephone call cannot be made through the extension line. Instead, the telephone call is made by calling an extension belonging to the attendant group. You can do

In addition, it is determined whether the extension with the login input is an extension designated as the attendant group (S15), and if the extension is assigned to the attendant group, the station is excluded from the attendant group (S16).

Table 4 shown below shows how the attendant database is changed when extension number 102 is activated by login.

Attendant Group ring 001 On 002 OFF

Table 4 Extensions excluded from the Attendant Group can be used as extensions assigned by the login rather than the originally assigned extensions. Therefore, the call from the trunk line may also be answered through the corresponding station only when the call is made by designating the corresponding extension number assigned by the login (S17).

If a call is made by specifying a specific extension number on a CO line, but the extension number is not activated by login, a call can be made by calling a group of attendants. If the simple exchange provides the VMS, it may leave a voice message without calling the group of the attendant when the extension number called from the trunk line is not logged in.

When an extension subscriber logs in, an extension number corresponding to the entered password is displayed on the display window installed on the terminal. If there is a voice message left on the extension number, if there is a voice message, the code corresponding to the message listening is dialed. You can listen to voice messages. The voice message is not displayed on the display window as described above, and the message waiting tone is preferentially provided during off-hook to inform the user that the message exists and the voice message is displayed by the message listening code dial. Can listen.

The user dials the logout code to notify the user of the extension using the extension assigned to him (S18). If the port of the station belongs to the attendant group, the port is returned to the attendant group. If the port is not designated as the attendant group, only the station call is allowed and the call from the trunk line is not accepted.

And after logging in or after logging out, the station can be called only by the extension number originally set, but the station belonging to the attendant group can answer the call from the trunk line.

As described above, the present invention allows any user to designate one port of the simple switch as his own extension number by login so that the corresponding port can be answered in the call of the trunk line and the extension, and for other stations In addition to allowing calls only, the station designated by the operator group can be connected to the station in response to the call from the trunk line, thereby effectively utilizing the limited resources of the simple switchboard.
