It is possible to easily grasp which function button of which telephone terminal should be operated when answering an incoming call to itself.

  According to the present invention, audio data for notifying an incoming call including at least caller name information is output from the speaker unit based on the INVITE message. Thus, for example, by installing the speaker unit in an area that is not adjacent to the telephone terminal accommodated by the call control device on the called side, even if the called user is not in the vicinity of the destination telephone terminal The user can easily grasp that there is an incoming call to the user.

  The best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a system configuration of a call control system according to the present embodiment.

  As shown in FIG. 1, a call control device 100 that accommodates a telephone terminal 200 and performs call control such as connection and disconnection between telephone terminals is connected via an IP network 300 such as the Internet.

  In the present embodiment, the call control device (for example, call control server, exchange device (including PBX, business phone, button telephone device), gateway, home gateway, etc.) 100 is another call control device according to SIP (Session Initiation Protocol). Communicate with 100 and perform call control between a plurality of telephone terminals 200 accommodated therein. The call control device 100 on the calling side generates an INVITE message including address information and call name information of the caller and destination, and is described in the INVITE message sent from the caller by the call control device 100 on the callee side. Based on the address information of the called party, the incoming call processing is executed for the telephone terminal on the called side, and is specified based on the INVTE message from the speaker provided on the ceiling or the like in the facility via the speaker terminal. The user is notified of voice data including name information indicating the destination and calling party.

  The call control device includes a text-to-speech means (function) that recognizes a text data SIP message (INVITE message) and converts it into speech.

  One call control device in FIG. 1 is called a call control device (1), and the other call control device is called a call control device (2). Two telephone terminals 200 (TEL5 and TEL6) and an external speaker 70 (SP3) are connected to the call control device (1). In addition, four telephone terminals 200 (TEL1 to TEL4) and two external speakers 70 (SP1 and SP2) are connected to the call control device (2).

  The speaker 70 may be the one built in the call control device 100, but in the present embodiment, an external speaker (which may be a broadcasting facility) is connected to call a remote speaker from the telephone terminal 200. ing.

  The telephone terminals accommodated in the call control device (2) are grouped so that TEL1 and TEL2 are the first group and TEL3 and TEL4 are the second group. Grouping is often called a tenant dividing function, and is a function that calls all grouped telephone terminals when an incoming call is received with a predetermined number, for example. The grouping setting is performed in the call control device.

  Here, the INVITE message is a call control text generated in the call control device 100 on the calling side and transmitted to the call control device 100 on the called side when a call is established between telephone terminals in accordance with SIP. It is data. FIG. 2 shows an example of a part of the INVITE message. In FIG. 2A, the INVITE header 100F indicates that the message is an INVITE message, that is, a call setting request to the call control device 100 on the called side. In the To header 102F, identification information for specifying a destination is indicated. Specifically, “tel:” indicates a line number (for example, dial-in number) corresponding to the destination address, and “isub:”. Is an extension number corresponding to the subaddress of the destination. Further, FIG. 2B shows an example in which destination name designation information is stored in association with the destination address in the display name portion preceding “tel:”. . In the From header 104F, identification information for identifying the caller is indicated. Specifically, “tel:” indicates a dial-in number corresponding to the caller address, and “isub:” indicates a call. The extension number corresponding to the original subaddress is indicated. In this embodiment, an example in which a so-called “TEL URL method” is adopted as a method for specifying a caller or a call destination will be described. However, other methods such as “SIP URL method” may be adopted. I do not care.

  FIG. 3 is a diagram illustrating an example of the appearance of the telephone terminal 200. In FIG. 3, the telephone terminal 200 has a handset 202 that receives an operator's voice, a numeric keypad 204 that receives a telephone number, and a lighting lamp (not shown) that indicates a connection state of a line. A plurality of function buttons 206 for connecting the telephone terminal 200 to the line at the time of calling or calling, and a display unit 208 configured by a liquid crystal display or the like for displaying a caller telephone number (dial-in number) or the like are provided. Note that the telephone terminal 200 shown in FIG. 3 is merely an example of a general telephone terminal, and the telephone terminal that can be employed in the present embodiment is not limited to the telephone terminal 200 shown in FIG.

  The telephone terminal 200 of this embodiment is an example of a multifunction telephone (a telephone having a plurality of function buttons each having a display lamp), and is accommodated in the call control device 100 as the telephone terminal 200. In this type of telephone terminal 200, button information corresponding to each function button is transmitted to the call control device 100 when each function button is pressed. In the storage device of the call control device 100, the functions assigned to the individual function buttons are registered as information. The call control device 100 recognizes the function assigned to the push button by extracting registration information based on the received button information. Then, by executing a program corresponding to the function, line connection or holding according to the function, display lamp control, and the like are performed. Then, a specific line is assigned to each function button, and the function of the line button is given to them. That is, if a function button corresponding to a certain line of a certain telephone terminal 200 is pressed, the line and the telephone terminal are connected, and a display lamp corresponding to the function button indicates the state of the line. It will be displayed.

  The function buttons of the telephone terminal 200 are a line button that is set corresponding to each line and selects a line when making / receiving calls, a lamp (indicator) for each line button that displays the use status of the line, a hold button, and the like The user can directly select or hold a line by operating these buttons.

  Hereinafter, an example of a general call operation will be described.

  Calling: By pressing a function button set with an arbitrary line button function whose lamp is not lit (a line button in which the corresponding line is in an empty state), the telephone terminal 200 and the line are connected to be able to make a call. .

  Incoming call: If the incoming call circuit of the call control device 100 detects an incoming call from a line, a lamp corresponding to the incoming call line flashes in all the telephone terminals 200 and a call is made. When a line button (function button) whose lamp is blinking is pressed on an arbitrary telephone terminal 200, the incoming line is connected to the telephone terminal 200 and responds. At the same time, the state of the lamps corresponding to this line of all telephone terminals 200 changes from blinking to lighting. In the case of an incoming call with a number corresponding to the grouping, only the grouped telephone terminals 200 are called with the lamp corresponding to the incoming line blinking.

  FIG. 4 is a diagram illustrating functional blocks of the call control device 100. In FIG. 4, the CPU 10 expands a basic control program such as a BIOS program stored in the ROM 12 in the RAM 14, controls each unit via the bus 90, and performs call control. Further, the CPU 10 expands the program 40 stored in the storage device 30 to the RAM 14 and implements various functions by referring to various data stored in the database 50 as necessary.

  The speaker unit 70 includes a speaker terminal for connecting a built-in speaker and an external speaker. When the call control device 100 is installed in the vicinity of a telephone terminal or user, an internal speaker is used. When the call control device 100 is installed remotely from a telephone terminal or user, an external speaker is connected to the speaker terminal. However, a form used for notification and notification is conceivable.

  The button state storage unit 56 stores a button state table indicating the line availability or connection state of each function button provided in the telephone terminal as shown in FIG. 5 for each telephone terminal or a telephone terminal to which the same dial-in number is assigned. Remember for each group.

  In FIG. 5, the line connection state is registered in the button state table for each function button provided in the telephone terminal 200 accommodated in the call control device 100. In FIG. 5, “−” is registered in association with the function button in the line availability state, and the line number being used (for example, “100”, “200” for the function button in the line connection state is registered. ”Or other dial-in numbers) are registered in association with each other.

  The call processing unit 42 receives the INVITE message transmitted from the call control device 100 on the calling side via the IP network 300 via the communication interface 80, and describes the received INVITE message in the To header. The received call destination is identified, a line in the idle state is selected, and the incoming call processing is performed on the telephone terminal 200 of the call destination via the selected line. The telephone terminal 200 sounds a ringing tone indicating that there is an incoming call while turning on the lighting lamp of the function button 206 corresponding to the connected line, and prompts the user to respond.

  When the call processing unit 42 receives the INVITE message, the call processing unit 42 refers to the button state table indicating the state of each function button corresponding to the destination telephone terminal stored in the button state storage unit 56, and determines the function button in the empty state. The incoming call processing is executed on the destination telephone terminal 200 described in the To header of the INVITE message via the line assigned to the selected function button. The telephone terminal 200 sounds a ringing tone indicating that there is an incoming call while turning on the lighting lamp of the function button 206 corresponding to the connected line, and prompts the user to respond. The call processing unit 42 further updates the button state table for the destination telephone terminal stored in the button state storage unit 56. That is, the call processing unit 42 registers a dial-in number (telephone number) in the button state table in order to change the state of the function button corresponding to the line on which the incoming call processing is performed this time to the line connection state.

  The call information storage unit 52 stores a call information table in which call information for a dial-in number and call information for an extension number assigned to the dial-in number are shown. The nominal information table is referred to when the audio data generation unit 44 generates audio data including nominal information as will be described later. The call processing unit 42 on the calling side also refers to the case where the INVITE message is generated, and the call processing unit 42 on the calling side calls the name information corresponding to the destination address (dial-in number) set by the user. Is specified, and an INVITE message in which the specified name information is described in a predetermined position of the To header is generated and transmitted to the call control device on the called side to execute the calling process.

  FIG. 6 shows an example of the name information table. First, the dial-in number “500” is assigned to the call control device (1) by a contract with the network operator, and the dial-in numbers “100” and “200” are also assigned to the call control device (2). Shall.

  A general dial-in contract is one in which a plurality of numbers (additional numbers) are assigned in addition to the subscriber line number, and the incoming call number (subscriber line number or additional number) is sent from the network when an incoming call is received. However, the dial-in number in the present embodiment refers to the number dialed by the caller notified from the network or the other party.

  In the nominal information table of the call control device (2) shown in FIG. 6, for example, “X: (for example, department name)” is registered as nominal information for the dial-in number “100”, and the dial-in number “100” is registered. To the telephone terminal 200 (TEL1 and TEL2), extension numbers “10”, “20”, “30”, “40”, “50” are assigned, and extension numbers “10”, “20”, 20 ”, As name information for “30”, “40”, and “50”, “G: (for example, personal name)”, “H”, “I”, “J”, and “K” are registered.

  Also, “Y: (for example, department name)” is registered as the call information for the dial-in number “200”, the telephone terminal 200 (TEL3 and TEL4), and the extension number “a” for the dial-in number “200”. , “B”, “c” are assigned, and “A: (for example, personal name)”, “B”, “C” are registered as designation information for the extension numbers “a”, “b”, “c”. Has been.

  As can be seen from this naming information table, when the incoming call is made only with the dial-in number “100”, the dial-in number “100” + extension number “10” or “20” or “30” or “40” or “50” ”Is set so that both the telephone terminals 200 (TEL1) and (TEL2) are called (a plurality of extension numbers are assigned to one telephone terminal, You can receive calls by any extension number).

  In the case of an incoming call with only the dial-in number “200” and an incoming call with the dial-in number “200” + extension number “a” or “b” or “c”, the telephone terminal 200 (TEL3) And (TEL4) are set to be called.

  In this embodiment, TEL1 and TEL2 are described as two groups, and TEL3 and TEL4 are described as a second group. However, one or more groups are sufficient, and naturally there are three or more groups. Also good. Further, it is sufficient that one group has one or more telephone terminals, and there is no problem with three or more terminals.

  The voice data generation unit 44 specifies the source number and the destination number from the To header and From header of the INVITE message, and makes a voice call to the called party using a designation corresponding to the specified number. . In the case of FIG. 2A, since the dial information “100” is stored in the To header, it is recognized from the nominal information table that the incoming call is “X (department name)”, and the extension number Since dial information “10” is stored in the notation “issub”, it is recognized that the incoming call is directed to “G (personal name)” of “X (department name)”.

  Then, based on the recognized destination information based on the voice data template (text data) stored in the voice data storage unit 54, the voice data generation unit (text reading unit) 44 generates voice data indicating the name of the destination. . As the extension number notation, “extension” may be used in addition to “sub”. In the present embodiment, “issub” and “extension” are referred to as subaddresses.

  The voice data template here is, for example, an incoming call such as “(calling information of called line (dial-in) number) (calling information of called extension number)”. A template showing a message that can specify the destination is conceivable.

  That is, in this case, the speaker unit 70 (SP1) outputs “A phone is addressed to G (personal name) of X (department name)”.

  In the present embodiment, the line number and the speaker are associated with each other so as to make a voice call using SP1 for an incoming call related to the dial-in number “100” and SP2 for an incoming call related to the dial-in number “200”. Voice calls may be made simultaneously, or information for designating a speaker for each incoming call may be received by a SIP message (INVITE message, MESSAGE message, etc.) and controlled accordingly.

  Furthermore, in the case of the present embodiment, the incoming call with the dial-in number “100” + extension number “10” is a grouping that calls the telephone terminals 200 (TEL1 and TEL2) together. The function button information received from the terminal is also notified.

  For example, if the incoming call is displayed on the function button 5 of TEL1 and TEL2, “A phone is in contact with G (personal name) of X (department name). Please call me. " In this case, the template is: “(Calling information for the called line number) (Calling information for the called extension number)” ((Incoming call display) Please receive a call with the function button number.

  The call control device 100 manages the vacant state in the call for each telephone terminal and the use state of the function button for each telephone terminal, and one of the grouped telephone terminals (TEL1) is blocked during the call. If there is an incoming call, call the other available (TEL2) phone terminal and call “G (personal name) of X (department name). TEL2 No. 6 (No. 5 function button) Please receive a call in the case of a blockage). "

  It is also possible to use the information of the caller for voice call. The dial information “500” in the From header of FIG. 2A is extracted, and the dial registered in the destination information table such as a telephone directory is extracted. Compared with the information, it is also possible to add and notify the destination of the incoming call from the name information corresponding to the matched dial information.

  In the above embodiment, a name information table is provided on the receiving side, dial information described in the To header and From header of the INVITE message is extracted, and voice calling is performed using the name data corresponding to the dial information. However, the call control device 100 on the calling side may store the call information in the INVITE message and transmit it, and make a voice call using specific information in the INVITE message (text base). .

  FIG. 2 (b) shows an example of an INVITE message to which name information is added by the caller side call control device.

  In the To header of FIG. 2B, “X (for example, department name or name may be sufficient)” is stored as a display name before the Tel-URI. This display name is recognized, and this text data is voiced. Use it for a call.

  Further, a specific identifier (recognizable to each other) may be provided in the body of INVITE, text data may be transmitted, and the text data may be converted into speech and read out. In FIG. 2B, text data “X BUNO G SANE DENWASU. (Calling Mr. G in the X part)” is stored with a special identifier “h”. In this case, the call control device on the calling side has an information table for managing that the other party's dial-in number “100” belongs to the “X” part and the extension number “10” belongs to “G”. Needless to say, they are equipped.

  FIG. 7 is a flowchart showing a procedure of voice data generation executed when the voice data generation unit 44 acquires an INVITE message.

  In FIG. 7, when the call control device 100 on the called side receives the INVITE message transmitted from the call control device 100 on the calling side, the voice data generation unit 44 acquires the INVITE message (S100). Name information of line numbers (for example, dial-in numbers) is acquired from the To header and From header described in the INVITE message (S102). Next, the voice data generation unit 44 determines whether or not an extension number (“sub”, “extension”, etc.) is described in the To header and From header of the INVITE message (S104). If it is described as a result of the determination (the determination result of step S104 is affirmative “Y”), the audio data generation unit 44 refers to the name information table stored in the name information storage unit 52, and Name information corresponding to the extension number is acquired (S106). After that, or as a result of the determination in step S104, if the described extension number does not exist (the determination result in step S104 is negative “N”), the audio data generation unit 44 then adds the obtained name information to the name information. Based on this, voice data indicating an incoming call notification including name information of the called party and the calling party is generated (S106), and the voice data is output through the speaker unit 70 to notify the user (S108).

  As described above, according to the present embodiment, based on the INVITE message transmitted from the call-side call control device 100, the call-side call control device 100 identifies the call source and destination name information, and identifies them. The voice data notifying the incoming call based on the designated name information is generated, and the voice data is output by the speaker unit 70 as voice. Therefore, for example, by installing the speaker unit 70 in an area that is not adjacent to the telephone terminal 200 accommodated in the call control device 100 on the called side (for example, an area different from the area where the telephone terminal 200 is installed). Even if the called user is not in the vicinity of the destination telephone terminal 200, the user can easily grasp that the called user has been called.

  FIG. 8 is a flowchart showing a procedure in which the voice data generation unit 44 generates voice data including a calling source, a destination, and function buttons of the destination and outputs the voice.

  In FIG. 8, when the call control device 100 on the called side receives the INVITE message transmitted from the call control device 100 on the calling side, the voice data generation unit 44 acquires the INVITE message (S200). Name information of line numbers (for example, dial-in numbers) is acquired from the To header and From header described in the INVITE message (S202). Next, the voice data generation unit 44 determines whether or not an extension number (“sub”, “extension”, etc.) is described in the To header and From header of the INVITE message (S204). If it is described as a result of the determination (the determination result of step S104 is affirmative “Y”), the audio data generation unit 44 refers to the name information table stored in the name information storage unit 52, and Name information corresponding to the extension number is acquired (S206).

  After that, or as a result of the determination in step S204, if the described extension number does not exist (the determination result in step S204 is negative “N”), then, the voice data generation unit 44 stores the button state storage unit 56 in the button state storage unit 56. By referring to the stored button state table for the destination telephone terminal, the function button used for dial-in reception described in the From header in the INVITE message acquired in step S200 is specified (S208). Subsequently, the voice data generation unit 44 obtains each of the acquired nominal information, terminal identification information that identifies the destination telephone terminal, and button identification information that identifies the identified function button (for example, “function button 1”). ) Is generated (S210). For example, the voice data generation unit 44 generates voice data such as “There is a phone call from Mr. A of Y company to the function button 1 of the telephone terminal 1 to Mr. G of the X part”, and the speaker unit 70. The voice data is output via voice and notified to the user (S212).

  As described above, according to the above, since the voice data including the button identification information for specifying the function button of the telephone terminal to which the incoming call is assigned is reported in addition to the caller name and destination name information, the user can Based on the notification, it is possible to easily grasp which function button of which telephone terminal should be pressed when responding to an incoming call to itself.

  Further, by providing a plurality of speaker units 70 in the call control device 100 and associating at least one extension number with each speaker unit 70, the voice data generating unit 44 can respond to the extension number of the destination. The speaker unit 70 that outputs sound may be changed. In this way, by associating an appropriate speaker unit 70 for each extension number, it is possible to prevent unnecessary sounds from being output to the speaker unit 70 installed in a place not directly related to the destination user. can do.

  Furthermore, in the above embodiment, the call control device 100 on the calling side describes the call information corresponding to the dial-in number as the call destination or call source call information in the To header and From header of the INVITE message ( Display name) was explained. However, the name information corresponding to the extension number, not the dial-in number, may be described in the body part of the INVITE message (area for transmitting information related to the call).

  In the above-described embodiment, an example in which the call control device 100 on the calling side creates the INVITE message has been described. However, the creation of the INVITE message is not limited to the call control device 100 on the calling side. It may be executed by the telephone terminal on the side.

  In addition, in the above-described embodiment, an example has been described in which call destination or caller name information described in predetermined positions in the To header and From header of the INVITE message is acquired and output as voice. However, a desired message message that has been reported to the called party in advance is described as text information at a predetermined position in a predetermined header portion other than the To header and From header of the INVITE message, and voice data including the text information is recorded. The message may be generated by the voice data generation unit 44 on the called side, and a message other than the caller name and destination name information may be output from the speaker unit 70 by voice. The message message is transmitted, for example, by sending text data indicating the message message from the calling side telephone terminal 200 to the calling side call control device 100 at the time of calling, and the calling side call control device 100 sends the INVITE message. When generating the text data, the text data may be described as a message message in a specific body part.

  Further, the text information to be read may not be transmitted as an INVITE message, but may be transmitted using an MESSAGE message for instant message transmission after the INVITE message is transmitted.

  When this MESSAGE message is used as well as a voice call of the telephone, the text data in the MESSAGE message can be output from the speaker unit 70 regardless of whether the telephone terminal 200 is on standby or during a call. As a result, there are more opportunities for operating call control devices, etc., and cooperation between broadcasting facilities can be strengthened more than ever.

  Specifically, using a MESSAGE message from a PC (personal computer) or the like, a speaker specification and a document to be output by voice are transmitted to the call control device. The call control apparatus that has received the MESSAGE message converts the text document into a voice and outputs it from a designated speaker. Using this function, notifications, alerts, and other notifications can be transmitted (notified) by a very simple operation of inputting (transmitting) text data.

  As described above, according to the present embodiment, based on the INVITE message transmitted from the call control device 100 on the calling side, the call control device 100 on the callee side specifies the call source and destination name information.
