    PURPOSE: A method for selectively utilizing an office line is provided to maintain security and to make an exchange manager change a system setup from a remote place, by changing an office line mode of a small-sized private exchange according to caller identifications (IDs), and by restricting access to system internal functions according to the caller IDs when a direct inward system access (DISA) mode of the office line is utilized. CONSTITUTION: A method for selectively utilizing an office line using caller identifications (IDs) comprises the steps of: if the office line is called, deciding whether an office line mode is a direct inward system access (DISA) mode or a general mode, and if the office line mode is not the general mode, deciding whether the office line mode is the DISA mode; if so, performing operations with the DISA mode, and if not, performing operations with the general mode, then if the mode is the DISA mode, deciding whether an entry corresponding to a call ID exists in an office line operation mode setup table; if not, operating with the general mode, and if so, delivering a dial tone or a vice announcement, and deciding which mode is selected by a user; if the user selects a setup changing mode, performing a setup program by a permission, and if the mode is for occupying other office line, occupying the other office line, then if the mode is for calling an extension, calling the extension by the permission, and if the mode is for connecting a voice mail system, connecting the voice mail system, and if every menu is not permitted, delivering an error tone or a voice announcement.

    Selective trunk line using caller ID {WIRE USE METHOD OF SELECTION USING CALLER IDENTIFICATION}
    The present invention relates to a selective trunk line using method using a caller ID, in particular, when setting the trunk line operation method of the private exchange, the mode of the trunk line can be changed according to the telephone number of the caller, and the operation mode table is stored and the direct system access mode. The present invention relates to a selective trunk line using method using a caller ID, which allows access to a class by caller ID even during operation.
    The CO line mode setting of the private exchange which is widely used in the office environment is divided into general mode and direct inward system access (DISA) mode.
    As shown in Fig. 1, the general trunk line mode is to ring a ring directly to a predetermined extension for the trunk line, and in the case of the DISA mode as shown in Fig. 2, when a call is made to a trunk line, the private exchange first receives a call. It will behave according to the response of the caller who sends out the call again.
    Examples of the operation in the DISA mode include extension connection, voicemail check, and system setting change.
    However, since the trunk line set in the DISA mode always operates only in the DISA mode, when a number of trunk lines of a small private exchange of about 2 to 8 trunk lines are used in the DISA mode, a call is made to the trunk line designated as DISA. There was an inconvenience of going through several steps.
    Therefore, the present invention devised in view of the above problems allows the mode to be changed according to the caller ID when the operation mode of the private exchange is set, and also allows the user to directly access the system by assigning a grade for each caller ID during the operation of the DISA mode. The purpose is to provide a selective use of trunk line using a caller ID.
    1 is a schematic view showing the operation in the case of a general trunk line mode.
    Figure 2 is a schematic diagram showing the operation in the case of the DISA trunk line mode.
    Figure 3 is a flow chart for a selective trunk line using method using the present invention caller ID.
    4 is a diagram showing an example of system setting in FIG.
    FIG. 5 is a diagram showing a trunk line operation mode setting mode in FIG. 3; FIG.
    The present invention for achieving the above object is a first step of determining whether the CO line mode is DISA / normal mode when the CO line is called, and determines whether the CO line mode is the DISA mode if not the DISA / normal mode; If it is determined in the first step that the DISA mode, the operation in the DISA mode, the operation in the non-disa mode, the normal mode, if the DISA / normal mode, determines whether there is an entry corresponding to the caller ID in the CO line operation mode setting table Performing a second step; A third step of determining whether a user selects a menu after transmitting a dial tone or a voice prompt if the entry is present, operating in a normal mode if the entry is not present; If the menu selected by the user in step 3 is a setting change, the setting program is executed according to the permission; if the foreign country is occupied, the foreign country is occupied according to the permission; the internal call is made according to the permission; The voicemail is connected according to the above, and if each of the above menus is not allowed, an error tone or a voice guide is transmitted.
    Hereinafter, with reference to the accompanying drawings, the operation and effects on the selective trunk line using method using the caller ID according to the present invention will be described in detail.
    3 is a flowchart illustrating a selective trunk line using method using the present invention caller ID. As shown in FIG. 3, when the trunk line is called, it is determined whether the trunk line mode is DISA / normal mode. A first step of determining whether or not to enter a mode; If it is determined in the first step that the DISA mode, the operation in the DISA mode, the operation in the non-disa mode, the normal mode, if the DISA / normal mode, determines whether there is an entry corresponding to the caller ID in the CO line operation mode setting table Performing a second step; A third step of determining whether a user selects a menu after transmitting a dial tone or a voice prompt if the entry is present, operating in a normal mode if the entry is not present; If the menu selected by the user in step 3 is a setting change, the setting program is executed according to the permission; if the foreign country is occupied, the foreign country is occupied according to the permission; the internal call is made according to the permission; According to the fourth step of connecting the voice mail according to the voice mail, and if each of the above menu is not allowed, the operation of the present invention will be described.
    First, as an example of system configuration, FIG. 4 adds a DISA / general mode as compared to the conventional case and accordingly defines an operation of each trunk line set to DISA / general mode as shown in FIG. 5.
    For example, if a call comes to CO line 3 of FIG. 4, the private exchange searches for the CO line operation mode setting table as shown in FIG. 5 with the caller ID and operates in DISA mode according to the contents of the table. If no information is available, it will run in normal mode.
    Here, when searching the caller ID of FIG. 5, the number of entries is reduced by using a regular expression, and the search is sequentially performed from upper to lower.
    For example, if the caller ID is 526-4833, all the first to third entries are applied, but the search is performed sequentially from the top, so that all system internal functions of setting change, foreign line occupancy, extension call, and voicemail connection are applied. It becomes accessible.
    As another example, when the caller ID is 526-4134, it corresponds to the third entry, so it operates in the DISA mode but cannot access the setting change and other station occupancy functions.
    As described in detail above, the present invention can flexibly change the mode according to the caller ID, which is a limited resource of the small private exchange, and also access the internal functions of the system according to the caller ID even when using the DISA mode of the CO line. There is a limit to the security, so that the security can be secured, and also the exchange manager can change the system configuration urgently from a long distance.
