    The keyphone system and controlling method which is converting arrival of the post using e-mail}
    [11] The call forwarding key phone system using the e-mail according to the present invention relates to a system and method using the key phone system, and more particularly, the address of an e-mail that the call phone user wishes to be forwarded to when the phone phone user is placed in a situation where he / she cannot receive a call. When the user who is using the key phone system is not available, the call comes to the designated e-mail address, the caller is recorded, and the e-mail address is stored even if the telephone is not provided. The present invention relates to a key phone system that allows a caller to find out a caller who misses an incoming call and to make a call in case of an important call.
    [12] Key Phone System is a business telephone system for a business office that allows a predetermined number of telephone lines to be shared by multiple phones. They can send and receive calls from any phone, and the call can be transferred to another phone in advance. In other words, it is a system that can make a call between each phone, and can hold an incoming call and transfer it to another phone.
    [13] BRIEF DESCRIPTION OF THE DRAWINGS It is a figure explaining the structure of the conventional incoming call keyphone system.
    [14] Referring to FIG. 1, the conventional call forwarding key phone system is divided into an internal control unit for signal processing inside the key phone system and an external connection unit for signal processing with the outside of the key phone system. A subscriber processor 11 for detecting a hook state, detecting an input state of a button, transferring the detected state to a control device, and receiving a message from a controller to perform LEDs and various necessary functions; A storage unit 12 which stores various kinds of information necessary for call processing; A switching unit 14 for controlling switching between various devices; A key phone 15 connected to the key phone system and used; It is composed of a central control unit 16 to control the various components to perform the necessary work, the external connection is composed of a trunk line connection unit 13 that serves to detect and transmit a signal from the trunk line incoming from the external network. .
    [15] In addition, the trunk line connection unit 13 is connected to a public switched telephone network (PSTN) 17 to be connected to an external communication network.
    [16] Referring to the operation of the conventional call forwarding key phone system configured as described above, the overall operation is divided into two parts, first when the key-phone user enters the call forwarding information, and also when the call of the key phone subscriber from the external trunk line occurs The call is connected to a pre-stored trunk line.
    [17] In more detail, the process of inputting the call forwarding information by the key phone user includes the steps of the user inputting call forwarding information using the key phone 15, and the subscriber processor 11 inputs the incoming call forwarding information. Detecting, transferring the detected call forwarding information to the central control unit 16, and storing the information in the storage unit 12 by the central control unit 16. Call forwarding information is inputted as specified.
    [18] On the other hand, when a call is made from an external trunk line to a key subscriber, the process of connecting the call to a trunk line which has been transferred in advance is performed by the CO line connection unit 13 detecting a call of a subscriber of a key phone generated from the external trunk line, Transmitting the detected call from the trunk line connecting unit 13 to the central control unit 16, detecting the call from the central control unit 16, and determining whether the corresponding key phone subscriber is transferred to the storage unit 12; And instructing the trunk line connection unit 13 to occupy another trunk line when the incoming call of the corresponding key phone subscriber is switched. The trunk line connection unit 13 finds an available trunk line and returns information about the trunk line to the central controller 16. In the step of transmitting, the central control unit 16 transmits the external transfer number of the key-phone subscriber, which is requested to be transferred, stored in the storage unit 12 to the trunk line connecting unit 13. In the step, the trunk line connection unit 13 transmits the corresponding number to the trunk line network, if a caller response is generated from the trunk line network, the trunk line connection unit 13 detects the response, and the response detected by the trunk line connection unit 13 Transmitting to the central control unit 16, the central control unit 16 instructing the switching unit 14 to connect the originating trunk line with the incoming trunk line; The connection is made to the call.
    [19] However, in the conventional call forwarding key phone system, when a call is generated when the key phone user is absent, the key phone user who applied for call forwarding has to carry a call forwarded phone, and also has to answer the call unconditionally. The result is a waste of time, and if a phone call is an unnecessary call request to a key phone user, there is also an economic loss due to a useless call. This time or economic loss is not the same as that of modern advertisements and telemarketing. In the times, the situation is emerging as a bigger problem.
    [20] The present invention has been proposed to improve the above problems, and to provide a call forwarding key phone system and a control method for responding only to the phone that the key phone user needs to determine without having to receive the incoming call in real time unconditionally The purpose.

    [21] In order to achieve the above object, a call forwarding key phone system using an electronic mail according to the present invention includes an internal control unit in charge of signal processing in a key phone system so that incoming calls can be switched according to a subscriber's needs; It is characterized by consisting of an external connection consisting of a trunk line connection portion connected to the public switched telephone network to handle incoming and outgoing calls with the outside, and a mail delivery program connection portion connected to the Internet network to transmit information.
    [22] The method for controlling the key phone system includes an e-mail address input process in which a key phone subscriber directly inputs an incoming mail address by directly inputting a letter; An incoming / outgoing CO line incoming call, an external caller receiving step, a caller information receiving step receiving the caller's information, a sender information sending step transmitting the sender's information to the mail delivery program access unit, and a mail delivery program are activated to transmit the e-mail. Characterized in that the call processing process consisting of the transmission program operation step.
    [23] 2 is a view illustrating a configuration of a call forwarding key phone system using an electronic mail according to the present invention.
    [24] 2, a call forwarding key phone system using an electronic mail according to the present invention is divided into an internal control unit for signal processing inside the key phone system and an external connection unit for signal processing with the outside of the key phone system. The internal control unit detects the hook state of the key subscriber, transfers the input state of the button to the controlling device, and receives the message from the control unit and the subscriber processing unit 21 to perform the LED and various necessary functions, Memory unit 22 storing various information necessary for call processing, switching unit 24 for controlling switching between various devices, key phone 25 used in connection with key phone system, necessary components by controlling various components It is composed of a central control unit 26 to enable the external connection portion serves to detect and transmit a signal from the trunk line incoming from the external network. The trunk line connecting portion 23; It is composed of a mail delivery program connection unit in charge of the Simple Mail Transfer Protocol (SMTP) protocol.
    [25] In addition, in the key phone system according to the present invention, the trunk line connection unit 23 is connected to a Public Switched Telephone Network (PSTN) 29, and the postal delivery program connection unit 27 is connected to the Internet 28. Intercommunication with external communication networks is possible.
    [26] The operation method of the call forwarding key phone system using the electronic mail according to the present invention having the above-described configuration can be divided into two processes as in the prior art, in which one key subscriber enters a letter directly and the call forwarding address is to be forwarded. Entering the e-mail address input process, the other process is a call processing process to process the call to the subscriber key.
    [27] Referring to the control method of the call forward key phone system according to the present invention in more detail as follows.
    [28] First, a key phone subscriber inputs an e-mail address to be forwarded by directly inputting a character in the subscriber processing unit 21 when a key phone user presses a call forwarding button using a key phone to which a key phone system is applied. ; Preparing to receive the information recognized by the subscriber processor 21 to the central controller 26 and to receive an e-mail address to be forwarded thereto; After the central control unit 26 is ready to receive the information, the subscriber enters information on the desired number and code into the dial matrix of the key phone 25; Recognizing information input to the key phone (25) by a subscriber processor (21); Transmitting information recognized by the subscriber processor 21 to a central controller 26; Whenever the two-digit number is inputted, the information input by the central control unit 26 is converted into a character by a constant conversion method, and the converted character is stored in the storage device 3, and also the image display device of the key phone 25. Instructing the subscriber processor 21 to be displayed on the screen; Pressing, by the subscriber of the key phone, an input button for notifying the end of the input to the key phone 25 after the text input is completed; Recognizing an input button in the subscriber processor 21 and transmitting to the central control unit 26; The central control unit 26 registers the forwarded email address in the storage unit 22.
    [29] In the above description, a method of displaying a number input by using a dial metric of a keyphone as a character is used to convert the character into a character whenever two digits are input. The combination thereof is shown in Table 1 below.
    [30] Input numberConversion characterInput numberConversion character 21A22B 23C31D 32E33F 41G42H 43I51J 52K53L 61M62N 63O71P 11Q72R 73S81T 82U83V 91W92X 93Y12Z 13.* 3, *2:*One@ 00010One 202303 404505 606707 808909
    [31] By using the method shown in Table 1, a combination of numbers is converted into a character, and each converted character is added to form an e-mail address.
    [32] As described above, when the address of the e-mail to be forwarded is registered because the call cannot be received, the call processing process for processing the call for the key-phone subscriber is as follows.
    [33] When an incoming call is made to a key subscriber from the outside, the caller number is accepted at the CO line 23, and the caller number received at the CO line 23 is stored in the storage unit 22, and the central controller 26 is connected. Transmits the sender number and the forwarded e-mail address stored in the storage unit 22 to the postal delivery program connection unit 27, and the postal delivery program connection unit 27 sends a simple network management protocol (SNMP). Network management protocol) and send the sender's number to the e-mail mailbox, and then the central control unit 26 commands the trunk line connection unit 23 to restore the corresponding trunk line. This is done by a recovery method.
    [34] Figure 3 is a flow chart illustrating a method for the incoming call of the call forwarding key phone system according to the present invention.
    [35] Referring to FIG. 3 to describe in more detail the interaction between the various devices according to the passage of time how to handle the call to the call forwarding key subscriber subscriber, the incoming call step of calling the key call subscriber is transferred from the outside (ST10) If the incoming caller information receiving step (ST10) after receiving the incoming call to inform the incoming call subscriber information (ST10) if the caller information receiving function of the corresponding CO line (CLI, ANI, FSR, etc. depending on the type of CO line) It continues and if not, the line is cut off and the trunk line is restored.
    [36] In the caller information receiving step (ST20), if the caller enters his or her information, the call forwarding step (ST 30) is determined whether or not to switch the incoming call to the e-mail proceeds if you want to forward the call continues If not, the outgoing call is disconnected and the CO line recovers without giving a reply.
    [37] In the call forwarding step (ST 30), if it is determined to forward the call to the e-mail sender to send information on the sender and the name of the pre-stored e-mail address to the mail delivery program access unit (27 in Fig. 2) Entering the information transmission step (ST 40), the mail delivery program access unit (27 in Figure 2) enters the SNMP program operation step (ST 50) for transmitting the sender information to the corresponding email address by running the SNMP program and transmitting After this, the process goes to the CO line recovery step (ST 60) to recover the CO line without giving a response signal.
    [38] By changing the call forwarding to the e-mail mailbox when the key phone user is absent in the above manner, the key phone user can check his or her e-mail mailbox and answer only the necessary phone calls without having to answer all the incoming calls.
    [39] As described above, the call forwarding key phone system and the control method using the e-mail according to the present invention, when the key phone user is absent, instead of converting the incoming call to another phone as in the conventional caller to his e-mail mailbox Not only does it reduce the inconvenience of having to respond to all incoming calls by letting the user enter the information, but it is also possible to find out the originator of a call and receive an answer based on its importance even if there is no telephone connection.
    [40] In addition, it is possible to reduce unnecessary call requests, such as in the case of an incorrectly connected incoming call, thereby obtaining many advantages in terms of economy and time.
    [41] In addition, from the caller's point of view, by not receiving a response signal from the called party, it brings the effect of leaving missed incoming information to the other party without imposing a calling fee.
