(A) First Embodiment Hereinafter, a first embodiment of a caller number setting system, a caller number setting program, and a call control server according to the present invention will be described with reference to the drawings.

  In the first embodiment, for example, an embodiment when the present invention is applied to a call control server in a call center will be described. In particular, when a plurality of work groups are shared and a plurality of work groups share a line, a case where a caller number of a work group in charge of an operator is set and transmitted to a destination is illustrated.

(A-1) Configuration of First Embodiment FIG. 1 is a configuration diagram showing a configuration of a caller number setting system 10A of the first embodiment. In FIG. 1, a caller ID setting system 10A has at least an IP telephone 1 connected to a LAN 2, a telephone 7 connected to a public network 6, and a call control server 3 connected to the LAN 2 and the public network 6. Composed.

  The call control server 3 is a server that is connected to the LAN 2 and the public network 6 and performs call control of the IP telephone 1 accommodated via the LAN 2. In the first embodiment, various types of call control methods can be widely applied. For example, SIP (Session Initiation Protocol) and ITU-T H.264 are available. A method using 323 or the like can be applied.

  When the call control server 3 receives the call connection request from the IP telephone 1, the call control server 3 identifies the working group from the identification information (for example, IP address) of the IP telephone 1, and sets the caller number assigned to the working group. To notify the destination.

  As shown in FIG. 1, the call control server 3 includes at least a public network interface unit 31, a LAN interface unit 32, a communication processing unit 33, a terminal work management table storage unit 34, and a caller number management table storage unit 35 as internal configurations. Have.

  The public network interface unit 31 is a connection interface with the public network 6. The LAN interface unit 32 is a connection interface with the LAN 2.

  The caller number management table storage unit 35 stores a caller number management table 5 for managing caller numbers assigned to each of a plurality of work groups. Here, FIG. 1 illustrates a configuration example of the caller number management table 5. As shown in FIG. 1, the caller number management table 5 is a table in which work groups and caller numbers are used as items, and work groups and caller numbers assigned to the work groups are associated with each other. For example, in the caller number management table 5 shown in FIG. 1, a caller number “xxxx” is assigned to “Group 1”.

  The terminal work management table storage unit 34 stores the terminal work management table 4 in which the identification information of the IP telephone 1 used by the operator is associated with the work group to which the operator belongs. Here, FIG. 1 illustrates a configuration example of the terminal work management table 4. As shown in FIG. 1, the terminal work management table 4 is a table in which the IP address of the IP telephone 1 is associated with a work group. For example, in the terminal work management table 4 shown in FIG. 1, the IP addresses “192.168.1.1” and “192.168.1.2” are associated with the work group “group 1”. This indicates that the operator who uses the IP phones 1 of “192.168.1.1” and “192.168.1.2” is in charge of work of the work group “group 1”.

  The communication processing unit 33 performs call processing for the IP telephone 1 accommodated via the LAN 2. FIG. 2 is a block diagram showing internal functions of the communication processing unit 33. In FIG. 2, the communication processing unit 33 includes a work group search unit 331, a caller number search unit 332, and a call control unit 333.

  The work group search unit 331 searches the work group associated with the identification information (IP address) of the IP telephone 1 that has requested the call connection with reference to the terminal work management table 4.

  The caller number search unit 332 searches the caller number management table 5 for the caller number of the work group searched by the work group search unit 331.

  The call control unit 333 performs call control of the accommodated IP telephone 1, and when receiving a call connection request from the IP telephone 1, performs call control with the connection destination requested by the call connection request. The call control method performed by the call control unit 333 can be widely applied as described above, for example, SIP or ITU-T H.264. 323 or the like can be applied.

  When the call control unit 333 receives a call connection request from the IP telephone set 1, the call control unit 333 adds the caller number searched by the caller number search unit 332 to the call connection request message and sends the call destination (connection request). Is sent to (destination).

  The IP telephone 1 is a telephone terminal used by an operator, and is a telephone terminal that is connected to the call control server 3 via the LAN 2 and performs a call with the telephone 7 of the public network 6 under the call control of the call control server 3. . An IP telephone is an IP telephone that implements a telephone function using IP (Internet Protocol) as a communication protocol. For example, a telephone function is realized by software processing such as a fixed telephone terminal, a portable telephone terminal, or a so-called soft phone. This corresponds to a personal computer (PC) or the like. Although only one unit is shown in FIG. 1, a large number of IP telephones 1 are connected to the LAN 2.

  Further, as shown in FIG. 1, the IP telephone 1 is configured to include at least a LAN interface unit 11 and a communication processing unit 12. The LAN interface unit 11 is a connection interface for connecting to the LAN 2. The communication processing unit 12 is a processing unit that performs call processing with the call control server 3.

  The telephone 7 is a telephone connected to the public network 7 and is a telephone terminal of an external network. As shown in FIG. 1, the telephone 7 includes a public network interface unit 71 connected to the public network 6 and a communication processing unit 72 that performs call processing.

(A-2) Operation of the First Embodiment Next, the operation of the processing of the caller number setting system 100A of the first embodiment will be described with reference to the drawings.

  FIG. 3 is a flowchart showing an operation for performing processing in the call control server 3 of the first embodiment. FIG. 4 is an explanatory diagram for explaining the operation of the caller ID setting system 100A of the first embodiment.

  FIG. 4 illustrates a case where three IP telephones 1-1 to 1-3 are connected to the call control server 3. The IP addresses of the IP phones 1-1 to 1-3 are “192.168.1.1” for the IP phone 1-1, “192.168.1.2” for the IP phone 1-2, and “192.168” for the IP phone 1-3. .1.3 ”.

  In the call control server 3, the caller number management table 5 is set in advance and is stored in the caller number management table storage unit 35.

  First, when an operator designates a work group for which the operator is responsible, the operator operates the IP telephone 1 to select a work group for which the operator is responsible. The IP telephone 1 describes the identification information indicating the work group in the message, and creates a message specifying the work group. Then, the IP telephone 1 transmits a message for creating the work group to the call control server 3 via the LAN 2.

  Here, for example, when the IP telephone 1 designates the operator's work group using SIP, the IP telephone 1 describes the identification information of the work group designated by the operator in the work group registration message (for example, RESISTER). To the call control server 3.

  When the call control server 3 receives a message from the IP telephone 1 (step S201 in FIG. 3), the communication processing unit 33 determines whether the received message is a call request message (step S202 in FIG. 3). .

  In this case, since it is not a call request message but a work group registration message, the communication processing unit 33 obtains the source IP address of the received message and the work group identification information described in the received message. The terminal work management table 4 is created in association with each other and stored in the terminal work management table storage unit 34 (step S203 in FIG. 3).

  For example, when the operator of the IP telephone 1-1 specifies that the work group is “group 1”, the communication processing unit 33 sets the IP address “192.168.1.1” to the work group “group 1” based on the received message. Is created and stored in the terminal work management table storage unit 34. Similarly, the communication processing unit 33 also sets the IP address “192.168.1.2” as the work group “group 1” and the IP address “192.168.1.3” as the work group “group 2” for the IP phones 1-2 and 1-3. The terminal work management table 4 is created.

  Next, when the operator makes a call operation using the IP phone 1 when making a call to a destination on the public network 6, the IP phone 1 makes a call connection request to the call control server 3 ( Send outgoing request message. For example, INVITE corresponds to the call connection request message.

  When the call control server 3 receives a call connection request message from the IP telephone 1 (step S201 in FIG. 3), the communication processing unit 33 of the call control server 3 determines whether or not the received message is a call request message. Judgment is made (step S202 in FIG. 3).

  In this case, since it is a call request message, the communication processing unit 33 refers to the terminal work management table 4 to search for and obtain a work group corresponding to the IP address of the source of the received message (FIG. 3). Step S204).

  Next, the communication processing unit 33 refers to the caller number management table 5 to search for and obtain a caller number corresponding to the searched work group (step S205 in FIG. 3).

  And if the communication processing part 33 acquires the sender number of a work group, this sender number will be described in a message and the message which described the sender number will be transmitted to the public network 6 (step S206 of FIG. 3). As a result, the destination telephone 7 can know the caller number described in the received message, and can display it on the display unit of the telephone 7 or store it in the storage unit.

  For example, the case where the operator of the IP telephone 1-1 makes a call to the telephone 7 on the public network 6 is illustrated. In this case, when a call request message is given to the call control server 3 from the IP telephone 1-1, the communication processing unit 33 of the call control server 3 has the IP address of the message transmission source "192.168.1.1". Referring to the terminal work management table 4, it is searched that the work group of the operator who uses the IP phone 1-1 is “group 1”.

  The communication processing unit 33 of the call control server 33 refers to the caller number management table 5 and obtains that the caller number of the group 1 is “XXXX”. As described in the message and sent to the destination.

  For example, the communication processing unit 33 of the call control server 3 transmits the caller number in the From header of the INVITE message.

(A-3) Effects of the First Embodiment As described above, according to the first embodiment, the operator can easily set the work group in charge of the call control server 3 using the IP telephone 1. Further, when the operator makes a call, the caller number of the work group desired by the operator can be notified to the callee.

(B) Second Embodiment Next, a second embodiment of the caller number setting system, caller number setting program, and call control server of the present invention will be described with reference to the drawings.

  The second embodiment is different from the first embodiment in the method in which the call control server 3 generates the terminal work management table 4.

(B-1) Configuration of Second Embodiment FIG. 5 is a configuration diagram showing a configuration of a caller number setting system 10B of the second embodiment. In FIG. 5, the caller number setting system 10B includes an operator terminal 9 (9-1, 9-2) connected to the LAN 2, a telephone set 7 connected to the public network 6, and a call connected to the LAN 2 and the public network 6. And at least a control server 3.

  The operator terminals 9 (9-1 and 9-2) are terminals used by the operator. Generally, an operator responds to a customer while operating not only a telephone terminal but also a personal computer (PC). Therefore, in the second embodiment, one or a plurality of terminals used by the operator is referred to as an operator terminal 9.

  The operator terminal 9 (9-1 and 9-2) includes an IP phone 1 (1-1 and 1-2) and a PC 8 (8-1 and 8-2). Here, the IP telephone 1 includes a LAN interface unit 11 and a communication processing unit 12, and corresponds to the telephone terminal described in the first embodiment, for example, a fixed telephone terminal, a portable telephone terminal, and the like. To do. The PC 8 includes a LAN interface unit 81 and a communication processing unit 82, and corresponds to a personal computer such as a desktop type or a node type.

  The operator terminal cooperation management table storage unit 36 stores an operator terminal cooperation management table 21 indicating the relationship between the IP telephone 1 as the operator terminal 8 and the PC 8. Here, FIG. 6A illustrates a configuration example of the operator terminal cooperation management table 21. In FIG. 6A, the operator terminal cooperation management table 21 is a table in which an IP address assigned to the IP telephone 1 is associated with an IP address assigned to the PC 8. For example, in FIG. 6A, the IP address “192.168.1.1” of the IP telephone 1 and the IP address “192.168.1.11” of the PC 8 are associated with each other. This describes the correspondence between the IP telephone 1 used by the operator as the operator terminal 8 and the PC 8. The operator terminal cooperation management table 21 can be set in advance, for example.

  The PC login management table storage unit 37 stores a PC login management table 22 indicating the relationship between the operator and the PC 8 used by the operator. Here, FIG. 6B illustrates a configuration example of the PC login management table 22. 6B, the PC login management table 22 is a table in which the IP address of the PC 8 is associated with operator identification information (for example, an ID number). For example, in FIG. 6B, the IP address “192.168.1.11” of the PC 8 is associated with the operator ID “XXX”, and in this case, the PC 8 with the IP address “192.168.1.11” is used. The operator indicates “XXX”.

Here, FIG. 6C illustrates a configuration example of the call group management table 23. In FIG. 6C, the call group management table 23 is a table in which operator identification information (for example, an ID number) is associated with work group identification information. For example, in FIG. 6C, the operator ID “XXX” and the work group “Group 1” are associated with each other. This is because the operator of the operator “XXX” is assigned to the work group “Group 1”. Indicates that it belongs.

  FIG. 7 is a block diagram illustrating an internal function of the communication processing unit 39 according to the second embodiment. As illustrated in FIG. 7, the communication processing unit 39 according to the second embodiment further includes a terminal work management table creation unit 334 in addition to the function of the communication processing unit 33 according to the first embodiment.

  The terminal work management table creation unit 334 creates the PC login management table 22 and the call group management table 23 based on the information described in the message received via the LAN 2, and the created PC login management table 22, The call group management table 23 table is stored in the PC login management table storage unit 37 and the call group management table storage unit 38.

  The terminal work management table creation unit 334 also uses the IP phone 1 and work group used by the operator based on information described in the operator terminal cooperation management table 21, the PC login management table 22, and the call group management table 23. The terminal work management table 4 is created. The method for creating the terminal work management table 4 will be described in detail in the operation section.

(B-2) Operation of Second Embodiment Next, the operation of processing in the call control server 3 of the second embodiment will be described with reference to the drawings.

  FIG. 8 is a flowchart showing the operation of processing in the call control server 3 of the second embodiment. FIG. 9 is an explanatory diagram illustrating a method for creating the terminal work management table 4 according to the second embodiment. Further, FIG. 10 is an explanatory diagram for explaining the operation of the caller ID setting system 100B of the second embodiment.

  In the call control server 3, the caller number management table 5 is set in advance as in the first embodiment, and is stored in the caller number management table storage unit 35. Also, the operator terminal cooperation management table 21 is set in advance for each operator and stored in the operator terminal cooperation management table storage unit 36 (step S301).

  When the call control server 3 receives a message from the operator terminal 9 via the LAN 2 (step S201), the call control server 3 determines whether the received message is a call request message (step S202).

  When the received message is not a call request message, the communication processing unit 39 of the call control server 3 selects either (a) an operator ID corresponding to the IP address (PC) or (b) a work group corresponding to the operator ID. It is determined whether or not the data is described in the message (step S302).

  In step S302, when data describing the operator ID corresponding to the IP address (PC) is received, the process proceeds to step S303, and the communication processing unit 39 associates the IP address of the PC 8 with the operator ID and performs PC login. The management table 22 is created (step S303).

  For example, when the operator logs in by operating his / her own PC 8-1, the operator inputs his / her operator identification information, and the PC 8-1 transmits the data to the call control server 3. At this time, as shown in FIG. 9B, the communication processing unit 39 of the call control server 3 includes the IP address “192.168.1.11” of the PC 8-1 as the transmission source of the received data and the received data. The PC login management table 22 is created in association with the operator ID “XXX”.

  If the data describing the work group corresponding to the operator ID is received in step S302, the process proceeds to step S304, and the communication processing unit 39 associates the operator ID with the work group identification information to call group. A management table 23 is created (step S304).

  For example, when a work group in charge of an operator is determined, the operator operates his / her own PC 8-1 to input the identification information “group 1” and operator ID “XXX” of the work group in charge, and the PC 8 Transmits the data to the call control server 3. At this time, as shown in FIG. 9C, the communication processing unit 39 calls the operator ID “XXX” included in the received data in association with the work group identification information “Group 1”. A group management table 23 is created.

  The call group management table 23 may be created based on data received from the PC 8 of each operator by the call control server 3 as described above. The call group management table 23 based on the data received from the PC 8 of the manager to be determined may be created. That is, when the administrator determines the work group of each operator, the administrator inputs the operator ID belonging to the work group and transmits the information to the call control server 3. As a result, the communication processing unit 39 can receive a plurality of operator IDs belonging to the work group for each work group. Therefore, the call group management table 23 may be created from this data. The administrator may be an administrator for each work group, or may be an administrator who determines all work groups.

  Next, the communication processing unit 39 checks information stored in the operator terminal cooperation management table 21, the PC login management table 22, and the call group management table 23, and determines whether each data column is stored. (Step S305).

  When data is stored in each data column of the operator terminal cooperation management table 21, the PC login management table 22, and the call group management table 23, the communication processing unit 39 selects the operator terminal cooperation management table 21, the PC login management table. 22 and the call group management table 23 are used to create the terminal work management table 4 (step S306).

  For example, as shown in FIG. 6A, it is assumed that an operator terminal cooperation management table 21 is set in advance. Further, it is assumed that the PC login management table 22 and the call group management table 23 shown in FIGS. 6B and 6C are created by the processing in steps S303 and S304.

  For example, the case where the data of the work group corresponding to the IP telephone set 1-1 with the IP address “192.168.1.1” is acquired is illustrated.

  First, the communication processing unit 39 of the call control server 3, as shown in FIG. 9A, uses the operator's PC 8-1 that uses the IP phone 1-1 with the IP address “192.168.1.1” from the operator terminal cooperation management table 21. IP address “192.168.1.11” is acquired.

  Next, as illustrated in FIG. 9B, the communication processing unit 39 refers to the PC login management table 22 and obtains an operator ID “XXX” that uses the PC 8-1 “192.168.1.11”. To do. Further, as illustrated in FIG. 9C, the work group “group 1” corresponding to the operator ID “XXX” is acquired with reference to the call group management table 23.

  By performing such processing, the communication processing unit 39 can acquire the work group “group 1” to which the operator of the IP telephone set 8-1 belongs, as shown in FIG. As shown in FIG. 9 (e), the terminal work management table 4 is created by associating the IP address “192.168.1.1” of this IP telephone set 8-1 with the work group “group 1”.

  In this way, the terminal work management table 4 can be created. The caller ID setting process returns to step S202 and is performed in the same manner as in the first embodiment.

  As a result, as shown in FIG. 10, when the operator terminal 9-1 of the operator belonging to the work group “group 1” makes a call to the telephone 7 on the public network 6, the caller number “XXXX” of the group 1 When the operator terminal 9-2 of the operator belonging to the work group “group 2” makes a call to the telephone set 7 on the public network 6, the caller number “YYYY” of the group 2 is set.
