Abstract

PURPOSE: A method for selectively transmitting a caller ID in a private exchange is provided to receive an accurate caller ID in a termination side by directly registering the caller ID in a database and operating the caller ID. CONSTITUTION: An operator of a private exchange collects separate caller ID information from subscribers, registers the collected caller IDs in a database, and registers local numbers and extension numbers, which are used in subscriber telephones, in the database(S1). If a subscriber attempts an external call(S2), a control unit of the private exchange judges whether the subscriber wants to transmit an extension number of the subscriber(S3). If the subscriber wants to transmit the extension number of the subscriber, the control unit combines a local number, a separate caller ID and the extension number(S4). The control unit transmits the combined caller ID to a remote station(S5). If the subscriber does not want to transmit the extension number of the subscriber, the control unit combines the local number and the separate caller ID(S6) and transmits the combined caller ID to the remote station(S5).

Description

Selective Sending Method of Private Exchange {Method for transmitting caller ID selectively of PBX}

The present invention relates to a calling number display service, and more particularly, a function of transmitting a calling number by adding a local number desired by a caller using a database when using a direct outward dialing (DOD) trunk line in a private exchange. The present invention relates to a selective transmission method of a calling number of a private exchange.

Recently, Caller ID (CID) service has been implemented, but there are many private carriers in large-capacity private exchanges, which may cause DID (Direct Inward Dialing) destination station numbers to have different DID lines (for example, 2000-). 1234, 4000,5678, etc.).

If the exchange uses the same DOD trunk line, the calling number transmits the same local number for the same route or channel (eg local number + extension number).

In this case, since the caller ID cannot be transmitted to the caller's DID number, a problem occurs when the caller views the received caller ID and misses the call and the other subscriber.

Therefore, the present invention has been made to solve the above problems, to enable the exchange operator to selectively handle the transmission of the calling number to transmit a combination of the desired number to the operator in the desired form to completely service the calling number service The purpose of the present invention is to provide a selective transmission method of a calling number of a private exchange.

In order to achieve the above object, the selective calling method of the private exchange according to the present invention collects the individual calling number indication information from the subscribers of the private exchange, and registers the local number and the extension number used in the subscriber phone in the database. Making a step; The subscriber attempts an external call; Determining whether the subscriber wants to transmit the extension number when the subscriber attempts to make an external call; When the subscriber selects to transmit the extension number, the calling number is combined with the own country code, the individual calling number, and the extension number and transmitted to the power station; And when the subscriber chooses not to transmit the extension number, the calling number is combined with only the own number and the individual calling number and transmitted to the large country.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

1 is a block diagram of a private exchange according to an embodiment of the present invention.

As shown in FIG. 1, the private exchange according to the present invention includes a control unit 5 which provides various services to subscribers and controls overall operations of each unit of the private exchange; A memory 6 for storing programs and processing data necessary for performing basic calls and various functions in the control unit 5; A trunk line circuit 1 which occupies the trunk line in accordance with a control signal of the controller 5 to form a trunk line call loop and interfaces a signal between the trunk line and the controller 5; A subscriber circuit (3) for connecting an extension and trunk line selection to the digital phone subscriber according to a control signal of the control unit (5), supplying power to the digital phone subscriber, and interfacing input / output data between the digital phone subscriber and the control unit; A switching circuit 4 for switching trunk lines and subscribers and for switching various tones and devices in accordance with a control signal from the controller 5; A tone generator 11 generating various tones according to a control signal of the controller 5 and outputting the tones to the switching circuit; A dual tone multi frequency (DTMF) receiver 12 for analyzing the MFC signal output from the general telephone of the extension subscriber and outputting the corresponding number to the controller; A DTMF generator 13 for generating a multi-frequency code (MFC) signal according to a control signal of the controller 5 and outputting it to a switching circuit; A voicemail box 14 for recording and supplying announcements and for recording messages; An MFC receiving unit 15 for analyzing the MFC received from the calling party to the called party when the R2 method is used in the inter-station signaling method and outputting the DSP to the controller; When using the R2 method in the inter-station signaling method, the subscriber consists of the MFC generation unit 16 for transmitting a digit or transmission grade transmitted from the CO line.

2 is a flowchart illustrating a method for selectively transmitting a calling number of a private exchange according to an embodiment of the present invention.

In order to selectively transmit the calling number according to the present invention, the operator of the private exchange should first determine how to generate and transmit the calling number.

This may be determined according to the type of business (eg, call center, help desk, after-sales service, separate carrier, home shopping, carrier, CTI, etc.) of the user using each private exchange.

Caller ID generation is divided in the following way.

1. Extension number

2. Individual call number

3. Country code

4. Individual call number + extension number

5. Local number + extension number

6. Local number + individual calling number

7. Local number + individual call number + extension number

In this way, if the station number is to be generated and displayed on the calling party number, the station number is added to the CO line. If the individual call number is to be generated and displayed, the individual calling number is registered at the subscriber port.

In addition, when transmitting a representative call number, the calling number is transmitted according to the database setting.

An operation of the present invention for selecting and transmitting a source information display service type in the private exchange configured as described above will be described with reference to FIG.

First, the operator of the private exchange collects individual calling number indication information from subscribers in the initial stage of the facility, registers this number in the database, and registers the local number and the extension number used in the subscriber's phone in the database (S1).

If the subscriber attempts an external call after the calling numbers are registered (S2), the control unit (not shown) of the exchange determines whether the subscriber wants to send the extension number (S3).

If the subscriber chooses to transmit the extension number in S3, the calling number is combined with the own number, the individual calling number and the extension number (S4) and transmitted to the power station (S5).

On the other hand, if the subscriber selects that the extension number is not transmitted in S3, the calling number is combined with only the own number and the individual calling number (S6) and transmitted to the power station (S5).

In this way, the caller ID service is completely performed because the called party can see the desired caller ID indication from the called party.

Although the preferred embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that the present invention may be modified without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Therefore, changes in the future embodiments of the present invention will not be able to escape the technology of the present invention.

As described above, according to the present invention, since the operator directly registers and manages the calling number in the database, the called party can receive the correct calling number information, so that the calling party and the receiving party can smoothly receive the calling information display. have.
