[0059] Next, the whole operation of this embodiment will be explained in detail.

[0060] First, the general operation of the call center agent clients 30 installed on a floor of the call center 100 is as follows:

[0061] When a web browser is started up, and information of an operator ID code and an ACD attendant's switchboard extension number are input to the CTI server 60, the call center agent clients 30 make a request of log-in processing to the CTI server 60. Then, the CTI server 60 executes log-in processing therein and makes a request of a log-on processing to the ACD system 10 by using the above-described information.

[0062] The ACD system 10 that received the request conducts log-on processing therein, and notifies the CTI server 60 that the processing was normally completed.

[0063] The CTI server 60 that receives this notification transmits web screen information (referred to as a form data, hereinafter) of a call center agent screen, which notifies that log-in to the CTI server 60 was conducted, to the call center agent clients 30.

[0064] In addition, at this time, the ACD system 10 notifies the multifunction telephone software 31 for emulating the ACD system exclusive telephone function which operates on the web browser that log-on to the ACD system 10 was conducted, and notifies the multifunction telephone software 31 of condition setting of a telephone set.

[0065] Next, when a call from the telephone sets 5 of clients of the call center arrives at the ACD system 10 by way of the public network 1 and a trunk circuit 11, and is equivalently distributed and connected to a call center operator most suitable for the reception of the call (reception request call), and to the call center agent client 30 by way of a digital line circuit 12, the ACD system 10 transmits termination notification to the CTI server 60, to which information relating to a termination such as an addresser discrimination number and an addresser dial number, is added.

[0066] The CTI server 60 conducts retrieval of the client database 70 while making the information relating to the termination call, such as an addresser discrimination number and an addresser dial number, to be a key, and notifies the call center agent clients 30 of a retrieval result as a form data.

[0067] Further, FIG. 9 is a condition transition view of the multifunction telephone software for emulating the ACD system exclusive telephone function by which the call center agent clients and the home agent clients operate on the web browser, and by means of the operation of the call center agent screen, by way of the multifunction telephone software 31 for emulating the ACD system exclusive telephone function which operates on the web browser, the ACD system 10 conducts condition transition of the call center agent clients 30 as shown in FIG. 9, and the CTI server 60 transmits a form data corresponding to the operation of the call center agent screen to the call center agent clients 30.

[0068] In addition, log-out processing of the call center agent clients 30 is executed in accordance with the same procedure of the log-in processing.

[0069] In other words, condition transition shown in FIG. 9 is into five conditions of a log-off mode, a work mode, a ready mode, a work reservation mode, and “during call”. The log-off mode indicates condition in which log-in to the CTI server is not conducted, the work mode indicates condition in which the reception of a call is temporarily suspended under condition of log-in to the CTI server 60, and local processing is desirable, the ready mode indicates condition in which a call is received, and the “during call” indicates condition in which a call is received in the ready mode, and communication is conducted, and a break mode indicates condition in which every processing is suspended under condition of log-in to the CTI server 60 (, which is set in case that an operator leaves his or her seat for a rest, for example), and the work reservation mode indicates condition in which the reception of a call is temporarily suspended during call by setting the work mode during call. As shown in FIG. 9, transition from one condition to other condition is conducted by clicking (pushing) a button displayed on a screen or conducting communication of call. In an example of FIG. 9, there are buttons of log-off, log-on, break mode setting/cancellation and work mode setting/cancellation.

[0070] FIG. 8 is a flowchart showing log-in/log-of processing of the home agent clients, FIG. 10 is a sequence chart showing log-on processing of the home agent clients in FIG. 1, FIG. 11 is a sequence chart showing log-off processing of the home agent clients in FIG. 1, and FIG. 12 is a sequence chart showing condition transition (a work mode, a ready mode, call, release and a work mode) of the home agent clients and voice information distribution processing of the CCGW in FIG. 1.

[0071] On the other hand, with regard to the operation of the home agent clients 90, as shown in a flowchart of FIG. 8 and sequence charts of FIG. 10 to FIG. 12, the home agent clients 90 operate in accordance with the same processing in the operation of the call center agent clients 30 through the agency of the CCGW 50.

[0072] First, the home agent clients 90 are connected to the ISP's 6, and start up a browser (step S1 and S2 in FIG. 8).

[0073] When an address by means of HTML (Hyper Text Markup Language) of the CCGW 50 of the call center 100 is input after the start up of the browser, the home agent clients 90 open a home page of the CTI server 60 by way of the CCGW 50, and read out a corresponding form data by means of a screen operation (step S3)

[0074] Then, the CTI server 60 sends the home agent clients 90 the form data corresponding to the screen operation. Thereafter, the home agent clients 90 display the form data on the screen, and when an ID code and an attendant's switchboard number to the displayed form data are input, the home agent clients 90 make a request of log-in processing to the CTI server 60. The CTI server executes log-in processing therein, and makes a request of log-on processing to the ACD system 10 based on the received ID code and attendant's switchboard number. The ACD system 10 that received the request by way of the IPGW 20 conducts log-on processing therein, and notifies the CTI server 60 that the processing was normally completed. The CTI server 60 that received this notification transmits a form data of a call center agent screen, which notifies the home agent clients 90 that log-in to the CTI server 60 was conducted. At this time, if there is discrepancy between the received ID code and attendant's switchboard number and registered ID code and attendant's switchboard number, the CTI server 60 notifies the home agent clients 90 of an error and an error code. The home agent clients 90 display the received error and error code, and demand an input of an ID code and an attendant's switchboard number again (steps S4, S5 and S6).

[0075] If there is no error at this time, the home agent clients 90 display a client image by displaying the received form data (log-on message) on the screen (steps S7 and S8). Condition of the home agent clients 90 at this time is that of a work mode.

[0076] The condition of the home agent clients 90 is changed in accordance with the condition transition view in FIG. 9 by means of the screen operation or communication by an operator, and make the operator do various kinds of work in accordance to the change of the condition (step S9).

[0077] Before long, when the button of log-off is pushed after the condition is in a work mode, and the home agent clients 90 notify the CTI server 60 of the log-off, the CTI server 60 conducts log-off processing therein, and makes a request of log-off of the requested attendant's switchboard number to the ACD system 10. The ACD system 10 that received the request conducts log-off processing therein, and notifies the CTI server 60 that the processing was normally completed. The CTI server 60 that received this notification transmits a log-off message which notifies the home agent clients 90 that the log-off was conducted. When receiving this message, the home agent clients 90 display the log-off message on the screen, end the browser, and end dial-up connection (steps S10 to S14).

[0078] Also, as shown in the sequence view of FIG. 12, with regard to the distribution of voice information to the home agent clients 90, when the condition of the home agent clients 90 is moved and becomes to be a ready mode, a timer within the CCGW 50 operates, and at a time point of time-out, a voice information transmission request is executed in a voice information transmission process of the CCGW 50.

[0079] If there is no error at this time, the home agent clients 90 displays a client image by displaying the received form data (log-on message) on the screen (steps S7 and S8). Condition of the home agent clients 90 at this time is that of a work mode.

[0080] In other words, referring to FIG. 12, when the home agent clients 90 is in a work mode, and the work mode cancellation button is pushed, the home agent clients 90 notifies the CTI server 60 of a work mode cancellation request by way of the CCGW 50. When receiving this notification, the CTI server 60 makes a request of a work mode cancellation to the ACD system 10. Then, when receiving this cancellation request, the ACD system 10 sets a ready mode from the work mode for the corresponding attendant's switchboard number, and sends the CTI server 60 a ready mode notification by return. At this time, a mode table is stored in a storage section inside the ACD system 10 so that it can be understood which mode is set for each of the plurality of the home agent clients 90. When receiving this ready mode notification, the CTI server 60 transmits the ready mode notification together with a form data to the home agent clients 90 by way of the CCGW 50. Then, the home agent clients 90 display a screen of the ready mode, and transitions to the ready mode. At this time, since the home agent clients 90 is in the ready mode, in the CCGW 50, the time of the CCGW 50 operates, and at a time point of time-out, a voice information transmission request to the home agent clients 90 is executed in a voice information transmission process of the CCGW 50. Accordingly, various kinds of voice information can be collected in accordance with a menu screen from the home agent clients 90 through the CCGW 50. In other words, the control section 501 of the CCGW 50 provides various kinds of the voice information by reading out a voice data from the voice information DB 506 via the LAN transmit-receive section 504 while making the information corresponding to instruction of the menu screen from the home agent clients 90, and further, converting the read voice data into a voice packet and sending it to the home agent clients 90 via the internet transmit-receive section 502. The CCGW 50 is constructed so that, in case that a call is distributed and connected by means of the ACD system 10 before the time-out, the timer is cancelled, and the voice information request is not executed. Before long, when the home agent clients 90 moves to a ready mode from a “during call”, the timer of the CCGW 50 starts up again, and service of various kinds of voice information is provided again to the home agent clients 90 when the timer times-out.

[0081] In other words, in relation to characteristic of the telephone reception of the call center, at most busy time, a call continuously arrives from the telephone sets 5 of clients of the call center 100. Accordingly, it is considered that, after some interval from a time point when the “during call” condition moves to the ready condition, in case that a telephone connection request from the call center 100 does not exist, it becomes to be a slack condition. By providing various kinds of voice information service by means of timer processing in the CCGW 50 of the call center 100, an operator (namely, an in-home operator or an operator in a remote office) who does not work during a period of this slack time can effectively make use of his or her spare moments, which can contribute to relaxation in spare moments from his or her work, relief from tension to waiting on clients, effective utilization of communication notification from an operating center to the operator, and so forth.

[0082] On the other hand, when a call arrives from the telephone set 5 of a client of the call center, the ACD system 10, which makes a mode of the corresponding home agent clients 90 within the mode table to be a ready mode by means of a work mode cancellation request, retrieves the mode table in order to apply the agency of an operator to the home agent clients 90, and determines the home agent clients 90 to which the agency of an operator is applied, and notifies the CTI server 60 of this termination of the call by way of the IPGW 20. When receiving the setting of the call, the CTI server 60 retrieves the client database 70 connected to the CTI server 60, and adds a record data that was read out, and conducts termination notification to the home agent clients 90 by way of the CCGW 50. Then, the home agent clients 90 displays client information on a screen, and transitions to the “during call” state by sending a response notification to the telephone set 5 by return by way of the ACD system 10. At this time, the CCGW 50 begins communication by making the home agent clients 90 operable for termination discrimination sound or termination discrimination display and response thereto. Also, communication of voice between the telephone set 5 and the home agent clients 90 is executed via the IPGW 20. With regard to voice information that was converted into a packet, via the AWP's 91 of the home agent clients 90, voice is converted into a packet data or a packet data is converted into voice, respectively. Before long, when communication between an operator and a client is completed, the operator operates a release button in a telephone part of the home agent clients 90, and the home agent clients 90 send release notification to the ACD system 10 by way of the CCGW 50. Then, the ACD system 10 ends the call with the telephone set 5, and sets a mode of the corresponding home agent clients 90 within the mode table to a work mode, and notifies the CTI server 60 of the release notification, and conducts work mode notification to the home agent clients 90 by way of the CCGW 50. In parallel with this, when receiving the release notification, the CTI server 60 transmits a form data to the home agent clients 90. When receiving the form data, the home agent clients 90 display a client screen for showing a work mode.

[0083] In addition, in case that a call is distributed and connected to the home agent clients 90 before time-out, the timer is cancelled, and a voice information transmission request is not executed.

[0084] Next, a call record of the home agent clients 90 will be explained. FIG. 13 is a sequence chart showing call record processing of the CCGW in FIG. 1 by means of intention of an operator. With regard to the call record of the home agent clients 90, like a method of conducting a call record by means of intention of an in-home operator or an operator in a remote office, which is shown in FIG. 13, condition of the home agent clients 90 moves to “during calls”, and by means of the operation of the agent client screen, a call record request is issued to the CCGW 50.

[0085] The CCGW 50 applies media conversion to voice information, which was converted into an IP packet by executing the call record request in a call record process inside the CCGW 50, to create a digital audio file form such as a WAV, and realizes a call record.

[0086] The call record is continuously accumulated until call record cancellation notification or release notification of a call during call is sent to the CCGW 50 from the home agent clients 90.

[0087] FIG. 14 is a sequence chart showing automatic call record processing of the CCGW in FIG. 1.

[0088] Otherwise, like a method in which a system automatically conducts a call record for every call of the home agent clients 90, which is shown in FIG. 14, by receiving response notification in which the CCGW 50 is notified of condition transition of the home agent clients 90 in the response of a call, the. CCGW 50 executes a call record request in a call record process inside of the CCGW 50, and the call record operates until release notification of a call from the home agent clients 90 is sent to the CCGW 50.

[0089] Finally, the drawings showing the operation of voice communication of the CCGW 50 will be explained.

[0090] FIG. 5 shows that a call that arrived at the ACD system 10 conducts communication with the AWP 91, and that voice information converted into an IP packet retrieves an IP address of the corresponding AWP 91 in the ADB 505, and applies address conversion thereto, and transmits it to the internet 2.

[0091] FIG. 6 shows that, in the voice information transmission process inside the CCGW 50, media conversion is applied to information stored in an apparatus connected to the LAN 81 as the voice information DB 506, and the information is converted into an IP packet, and is transmitted to the corresponding AWP 91.

[0092] FIG. 7 shows that, in the call record process inside the CCGW 50, during call between a call that arrived at the ACD system 10 and the AWP 91, media conversion is applied to voice information converted into an IP packet, and forming of a digital audio file such as WAV is conducted, and it is accumulated in an apparatus connected to the LAN 81 as the voice information DB 506.

[0093] As explained above, if an operator such as an in-home operator and an operator in a remote office uses the home agent clients 90, it is impossible to conduct reception processing same as that in case of using the call center agent clients 30 of the call center.

[0094] Moreover, since, when a reception request call from the telephone set 5 is received, the home agent clients 90 capable of receiving the call are allocated by means of the ACD system 10, the call can be quickly connected to an operator (such as an in-home operator and an operator in a remote center) of a call center far from a call center.

[0095] Further, since IP packet communication can be conducted between the call center and the home agent clients, communication of voice and a data can be concurrently handled.

[0096] Furthermore, the present invention effects an advantage that, by conducting internet access by way of the ISP using an analog subscription circuit or an ISDN circuit, an in-home operator or a call center operator in a remote office can use a function same as the call center agent clients capable of concurrently handling communication of voice and a data. Further, as a result, the present invention effects an advantage that serious tasks of maintenance of resources of a brilliant operator in a call center system that continues to enlarge its scale, and maintenance of an area of a call center can be solved.

[0097] Also, the present invention effects an advantage that, since the call link between the call center and the home agent clients is maintained, connection processing of a call that arrived at the call center can be quickly processed.
