It is determined whether the '#' button signal, which is a button, is transmitted, and when the '#' button signal is transmitted, the corresponding extension terminals 41 to 43 are determined as automatic connection terminals.

Such a specific button signal can be determined by selecting a dual tone multi frequency (DTMF) generated by selecting a button of a '3 × 4' keypad included in the extension terminals 41 to 43.

2 is a flowchart illustrating a flow of a method for providing an automatic call service according to a preferred embodiment of the present invention.

Referring to FIG. 2, first, an automatic connection terminal information for selecting an automatic connection terminal item in order for an administrator or subscriber to automatically connect his terminal to an arbitrary phone number in an emergency, information on an incoming phone number to be called in an emergency, and Then, priority information on an incoming call to be called is set in the VMS 50.

The VMS 50 which has received such information stores each set information in the automatic connection table 54 (S1).

In this case, the automatic connection terminal information may be telephone number information or specific button signal information of the extension terminals 41 to 43.

Then, the automatic connection processing unit 52a of the VMS 50, when the extension subscriber lifts the handset / receiver of the extension terminals 41 to 43, when the hook-off state, that is, the hook-off signal is transmitted (S2), the corresponding extension terminal 41 43), the automatic connection table 54 determines whether or not the automatic connection terminal is set (S3).

As a result of the determination, the VMS 50 transmits an incoming call to the called telephone number transmitted from the extension terminals 41 to 43 when it is determined that the extension terminals 41 to 43 that have transmitted the hook-off signal are not auto-connect terminals. (S4).

On the other hand, when the automatic connection processing unit 52a determines that the extension terminals 41 to 43 that have transmitted the hook-off signals are set as automatic connection terminals, the automatic connection processing unit 52a searches for the highest priority incoming phone number in the automatic connection table 54. Then, the incoming call is sent to the called telephone number (S5).

That is, when the automatic connection terminal information is set to the phone number information of the extension terminals 41 to 43, the automatic connection processing unit 52a automatically connects the phone number information of the extension terminals 41 to 43 that have transmitted the hook-off signal. It is checked whether or not it is stored in the table 54, and if it is stored, the extension terminals 41 to 43 that transmit the hook-off signal are determined to be automatic connection terminals.

On the other hand, when a specific button signal is used when setting the automatic connection terminal information, the automatic connection processing unit 52a determines whether the hook-off signal is transmitted from the extension terminals 41 to 43 and whether or not the specific button signal is transmitted after a predetermined time. When the specific button signal is transmitted, the corresponding extension terminals 41 to 43 are determined to be automatic connection terminals.

For example, when the phone number information of the extension terminal # 1 (41) is set as an automatic connection terminal and the automatic connection table 54 shown in Table 1 is stored or the '#' button is set as a specific button. The automatic connection processing unit 52a checks in the automatic connection table 54 whether the telephone number information of the extension terminals 41 to 43 that transmits the hook-off signal is the telephone number information set as the automatic connection terminal.

On the other hand, the automatic connection processing unit 52a does not set the telephone number information of the extension terminals 41 to 43 that transmitted the hook-off signal as the telephone number information of the automatic connection terminal, or specifies a signal transmitted after the hook-off signal. If the button signal is a '#' button signal, the corresponding extension terminal (41 ~ 43) is determined as an automatic connection terminal.

In this case, the specific button signal may be arbitrarily selected by the VMS service manager. In addition to the '#' button, it is preferable to use this button when the terminal has a specific button indicating that the terminal is a separate automatic connection terminal in the '*' itself.

When the extension terminals 41 to 43 that transmit the hook-off signal are determined to be automatic connection terminals, the automatic connection processing unit 52a searches for the incoming telephone number information having the highest priority in the automatic connection table 54, Sends an incoming call to the called telephone number.

In addition, the automatic connection processing unit 52a transmits an incoming call to the incoming call number having the highest priority, and an external subscriber using an external terminal assigned to the incoming call number responds to the incoming call, so that the extension terminal ( 41 to 43) and whether or not the voice call is established (S6).

If there is no response to the incoming call, the automatic connection processor searches for an incoming phone number having the next priority and transmits the incoming call to the corresponding phone number (S7).

At this time, the automatic connection processing unit 52a determines that the call is not established if the call state of the external terminal or telephone station which has transmitted the incoming call is busy or if there is no response to the incoming call transmitted more than a predetermined number of times.

Then, referring to the automatic connection table 52, the automatic connection processor 52a repeatedly transmits an incoming call to all incoming phone numbers for a predetermined number of times set, or if there is no response to the incoming call for a predetermined time, the extension terminal. Voice guide information stored in the voice information storage unit 53 is transmitted to (41 to 43), and the input voice information is stored in the voice mailbox as emergency voice information.

Then, the automatic connection processing unit 52a reproduces the stored emergency voice information at the subscriber's request and provides a voice mailbox service (S7).

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, when an extension subscriber using a voice mail system (VMS) picks up / receives a receiver of an extension terminal and enters a hook state, an incoming call is automatically sent to an important telephone number in an emergency situation. There is an effect that can receive a voice call without the operation of a separate extension terminal.

In addition, an extension subscriber repeatedly transmits an incoming call to perform a voice call in an emergency situation, and when there is no response to the incoming call, emergency voice information may be delivered through a voice mailbox.
