1 is a connection diagram of a private exchange and a voice mail device according to the present invention;

A private exchange (eg a keyphone exchange) and a voice mail system (VMS) are installed to interwork with each other via their respective DLI / ALI cards. In addition, communication between each COMM. This is done through PORT (COMMUNICATION PORT). A facsimile (hereinafter referred to as a fax) is also connected to the private exchange. One or more faxes connected to the private exchange are connected in accordance with the present invention. The configuration of a private exchange interworking with the voice mail device is shown in FIG. It demonstrates with reference to FIG.

FIG. 2 is a block diagram of a private exchange interworking with a voice mail apparatus according to the present invention.

The controller 111 controls the call switching and controls the overall operation of the key phone system to provide various services to the user. The ROM 112 stores basic calls and programs and initial service data of the control unit 111 for performing various functions. The RAM 113 temporarily stores data generated during program execution under the control of the controller 111.

The switching circuit 114 switches various tones and voice data under the control of the controller 111. The subscriber circuit 115 supplies a call current to an extension subscriber (regular telephone and key phone telephone) under the control of the control unit 111 and simultaneously interfaces a signal between the extension subscriber and the switching circuit 114. Here, the extension refers to a line connecting the switching system and the subscriber telephone. The ring generator 116 generates a ring signal and supplies it to the subscriber line. The trunk line circuit 117 forms a trunk line call loop under the control of the control unit 111 to form a trunk line call loop, and interfaces a signal between the trunk line and the switching circuit 114. Here, the trunk line refers to a line connecting the trunk line circuit 117 and the national exchange period.

The tone generator 118 generates various tone signals under the control of the controller 111 and outputs them to the switching circuit 114. The DTMF receiver 119 analyzes the DTMF signal input from the switching circuit 114, converts the DTMF signal into digital data, and outputs the digital data to the controller 111. The DTMF signal input to the DTMF receiver 119 through the switching circuit 114 may be a telephone number generated by the trunk line subscriber or a telephone number generated by an extension subscriber. The DTMF transmitter 120 converts the digital data output from the control unit 111 into a DTMF signal and outputs the DTMF signal to the switching circuit 114. Here, the DTMF signal output from the DTMF transmitter 120 becomes the telephone number of the trunk line subscriber generated when the station side calls the trunk line side.

The present invention forms a configuration in which the VMS 200 is interlocked with the key exchanger 100. The VMS 200 is installed to interlock with each other via the key exchanger and the DLI / ALI card 121.

1 and 2 will be described in detail a preferred embodiment of the present invention.

3 is a control flowchart illustrating automatic fax switching in a voice mail apparatus connected to a private exchange according to an embodiment of the present invention.

In step 301, if the subscriber connected to the private exchange, the fax connected to the private exchange, or an external trunk line fax user enters the voicemail function of the VMS 200 via the DLI / ALI card of the key exchange, the flow proceeds to step 302. Thereafter, in step 302, the VMS 200 transmits a voice guide message according to a voice mail service through a communication line. For example, the voice message of the VMS 200 sent out is "Hello, it is a voice mail service. If you want to send a fax service after entering the mailbox number and password, dial the fax number, if you do not know the fax number start key Please press. If you would like other services, please press the asterisk. "

At this time, the user can use a variety of voicemail services by entering the mailbox number and password, enter the desired service number to enter the service. If the user inputs a fax transmission service for sending a fax message, in step 303, the VMS 200 checks whether a fax number is input from a user who enters a voice mail box. If no fax number is detected, go to step 305. If the user who enters the voicemail box wants to send a fax message in step 303, if the user knows the fax number to be transmitted, the user inputs the fax number directly and the VMS 200 detects the fax number. The fax is connected. However, even if a user who enters the voicemail box wants to send a fax message but does not know the receiving party's fax number, the present invention automatically switches to the corresponding fax to be connected. In step 305, the VMS 200 When a user who enters the VMS 200 who listens to the announcement message enters a fax transmission button while listening to the voice announcement message, a call tone is generated and transmitted to the VMS 200. The received VMS 200 receives the received message. When it detects a calling ringtone, it automatically switches to a fax connected to the private exchange and connects the user with the fax.

In this case, although not shown in the drawing, when the fax automatically switched in step 306 is busy, the fax is automatically switched to another fax connected to the private exchange.

In summary, the present invention; When an external fax user or a user inside a private exchange enters the VMS and wants to send a fax, the user can select a fax transmission service according to the voice prompt message.If the user enters a fax number connected to the private exchange, If the user does not know the fax number connected to the private exchange, but the user only enters the Send Fax button, the VMS automatically switches to the fax connected to the private exchange. If the converted fax is busy, it will automatically switch to another fax connected to the private exchange.
