1 is a diagram illustrating an example of an operating environment of a system according to an embodiment of the present specification. Referring to FIG. 1 , a user device 110 and one or more servers 120 , 130 , 140 are connected through a network 1 . 1 is an example for explaining the invention, and the number of user devices or the number of servers is not limited as in FIG. 1 .

The user device 110 may be a fixed terminal implemented as a computer system or a mobile terminal. The user device 110 is, for example, a smart phone, a mobile phone, a navigation system, a computer, a laptop computer, a digital broadcasting terminal, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a tablet PC, a game console (game). console), a wearable device, an Internet of things (IoT) device, a virtual reality (VR) device, and an augmented reality (AR) device. In one example embodiments, the user device 110 may actually use one of a variety of physical computer systems capable of communicating with the other servers 120 - 140 over the network 1 using a wireless or wired communication scheme. can mean

Each server may be implemented as a computer device or a plurality of computer devices that communicate with the user device 110 and the network 1 to provide commands, codes, files, contents, services, and the like. For example, the server may be a system that provides each service to the user device 110 connected through the network 1 . As a more specific example, the server may provide a service (eg, information provision, etc.) targeted by the corresponding application to the user device 110 through an application as a computer program installed and driven in the user device 110 . As another example, the server may distribute the above-described file for installation and operation of the application to the user device 110 , and may provide a corresponding service by receiving user input information. For example, the connection information server, the ARS server, and the service server shown below may be any one of the servers of FIG. 1 , and other servers may be any one of the servers of FIG. 1 . In addition, the user terminal and the operator terminal may be one of the users of FIG. 1 , and other terminals may also be one of the users of FIG. 1 . That is, each of the terminals and each server may operate in a manner of performing communication and exchanging data through a network, and is not limited to the above-described embodiment.

Also, as an example, a line for voice call exchange described below may be a Public Switched Telephone Network (PSTN) scheme. In this case, the PSTN may be a method of providing a voice call based on a telephone communication network. For example, when voice communication is performed based on the PSTN, quality of service (QoS) may be corrected by allowing the line to be called and used exclusively when the caller terminal makes a call to the receiver terminal. However, since a dedicated line is called between the caller terminal and the receiver terminal, communication with other terminals may not be possible until the call is terminated.

On the other hand, the Internet network may be a network using packets, and the Internet telephone line may be a method in which a caller terminal and a receiver terminal perform voice communication based on packet exchange. Circuits are not specifically limited by the packet switching method A plurality of circuits can be used. However, if the packet usage increases based on an increase in network usage, QoS may not be guaranteed.

Hereinafter, a method for providing a VARS service based on the PSTN (hereinafter referred to as an existing line) and a line using a packet-based Internet network (hereinafter, an Internet telephone line) will be described.

2 is a block diagram illustrating an internal configuration of the computing device 200 according to an embodiment of the present specification. The computing device 200 may be applied to one or more of the user devices 110-1 and 110-2 or the servers 120-140 described above with reference to FIG. 1, and each device and server may add some components or By being configured to exclude, it may have the same or similar internal configuration.

Referring to FIG. 2 , the computing device 200 may include a memory 210 , a processor 220 , a communication module 230 , and a transceiver 240 . The memory 210 is a non-transitory computer-readable recording medium, and is a non-volatile, high-capacity, non-volatile memory such as random access memory (RAM), read only memory (ROM), disk drive, solid state drive (SSD), and flash memory. It may include a permanent mass storage device.

The separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, a disk, a tape, a DVD/CD-ROM drive, and a memory card.

In another embodiment, the software components may be loaded into the memory 210 through the communication module 230 instead of a computer-readable recording medium. For example, the at least one program is a computer program installed by files provided through the network 1 by a file distribution system (eg, the above-described server) that distributes the installation files of developers or applications (eg, a computer program) It may be loaded into the memory 210 based on the above-described application).

The processor 220 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input/output operations. The instructions may be provided to the processor 220 by the memory 210 or the communication module 230 . For example, the processor 220 may be configured to execute a received instruction according to a program code stored in a recording device such as the memory 210 .

The communication module 230 may provide a function for the user device 110 and the server 120 -140 to communicate with each other through the network 1, and the device 110 and/or the server 120 - 140, respectively. This may provide a function for communicating with other electronic devices. Also, here, the communication module 230 may collectively refer to a library or applications required for call connection, line distribution, and VARS service.

The transceiver 240 may be a means for interfacing with an external input/output device (not shown).

Hereinafter, descriptions are made based on a terminal and a server for convenience of description, but the configurations may include various configurations as a computing device, and may not be limited to a specific computing device.

For example, in order to provide an ARS response (or automatic response) in an existing smart phone, a voice call (or voice call) may be received, and a service may be provided based on a predetermined item through the ARS response server. At this time, companies that have many stores and customers, such as card companies or home appliance companies, and companies that sell a lot of products can build and provide a server for ARS response. There may be limitations in building

In consideration of the above, a method for performing automatic reception in the user terminal will be described below. Furthermore, when the user terminal performs automatic reception, a method for the user terminal to provide a flexible answer according to a request rather than a preset item through the AI server will be described. That is, the following describes a method in which the receiver terminal provides an artificial intelligence assistant service that flexibly responds to various requests and responses of the sender terminal by using artificial intelligence.

3 is a diagram illustrating a method of providing a response to a request of a caller terminal through a voice call based on artificial intelligence according to an embodiment of the present specification.

The receiver terminal 320 may set automatic reception of a voice call delivered from the caller terminal 310 . For example, the receiver terminal 320 may be a carrier terminal, and may be a smartphone or other device. That is, the receiver terminal 320 is not implemented as a specific server, and may be a generally used device and may not be limited to a specific device. In addition, the caller terminal 310 may be a device of a user who wants to receive a service from a business operator. That is, the sender terminal 310 may be a device of a user who wants to receive a service from an operator based on the receiver terminal 320 .

In this case, referring to FIG. 3 , the receiver terminal 320 may receive a voice call (or voice call) from the caller terminal 310 . The user of the caller terminal 310 may attempt a voice call with the receiver terminal 320 based on identification information (e.g. phone number). For example, the sender terminal 310 and the receiver terminal 320 may perform data exchange by performing data communication with each other, and the embodiment is not limited thereto. Also, the receiver terminal 320 may perform data communication with the AI server 330 . That is, the receiver terminal 320 performs data exchange by communicating with the AI server 330 as a general device rather than a separate server, and can acquire desired information through this. The AI server 330 may be a server that processes the request of the sender terminal 310 and provides it to the receiver terminal 320 . As an example, the AI server 330 may be a server that has a learning model and is continuously updated by learning through a response to a request from a plurality of caller terminals 310 . As an example, the input of the AI server 330 may be a request from the sender terminal 310 , and the output may be a response to the request of the sender terminal 310 . The AI server 330 may continuously perform an update based on the above-described input and output, and may provide a flexible response to the caller terminal 310 based on the update.

As a specific example, when the receiver terminal 320 receives a voice call from the caller terminal 310, the receiver terminal 320 provides an automatic answer to the caller terminal 310, and based on the automatic answer, the caller terminal 320 ) can be processed. For example, when a voice call is automatically received by the receiver terminal 320 , the caller terminal 310 may transmit a query request to the receiver terminal 320 based on the voice call. That is, the user of the caller terminal 310 may transmit “query 1A” to the receiver terminal 320 by voice based on the automatic response. The receiver terminal 320 may transmit the query request message converted into text to the AI server 330 by processing “query 1A” from the sender terminal 310 by STT (Speech to Text) processing. Also, as an example, the receiver terminal 320 may generate a request from the sender terminal 310 as a voice file and transmit the generated voice file to the AI server 330 , but is not limited to the above-described embodiment. That is, the receiver terminal 320 may generate "query 1B" related to "query 1A" received from the caller terminal 310 in the form of a text or voice file, and transmit it to the AI server 330 . “Query 1B” may be in the form of a text or audio file and is not limited to the above-described embodiment. Thereafter, the receiver terminal 320 may receive "response 1A" which is a response to "query 1B" from the AI server 330 . In this case, “response 1A” may be in the form of a text or voice file. That is, the AI server 330 may respond to “Query 1B” to the receiver terminal 320 as a message in the form of a text message or a message in the form of a voice file. In this case, as an example, the AI server 330 may obtain “answer 1A” as an input and output “query 1B” based on the above-described learning model, thereby providing a flexible response.

Thereafter, the receiver terminal 320 may provide the "response 1B" to the sender terminal 310 based on the "response 1A". At this time, if the “response 1A” received from the AI server 330 is text, the “response 1B” may be provided to the sender terminal 310 after conversion to a voice file through text to speech (TTS) processing. On the other hand, when the "response 1A" calculated from the AI server 330 is a voice file, the receiver terminal 320 may provide the "response 1B" converted to voice to the caller terminal 310 based on the voice call. .

In addition, when the user of the sender terminal 310 has an additional query, as described above, the user of the sender terminal 310 performs an additional query request to the receiver terminal 320 , and the receiver terminal 320 provides a flexible response based on the AI server 330 . Information may be generated and provided to the caller terminal 310 .

Here, a method for specifying query information of the caller terminal may be required. As an example, when the response of the receiver terminal is delayed based on the inquiry to the sender terminal, service quality degradation may occur. In this case, when the scope of the query information of the sender terminal is wide, the information processing time of the AI server that receives the related information from the receiver terminal may be delayed, and based on this, delay may occur in service provision.

In consideration of the foregoing, referring to FIG. 4A , when the caller terminal 410 and the receiver terminal 420 perform an automatic answer based on a voice call, the receiver terminal 420 and the caller terminal 410 are related content can be determined. Here, the related content may be determined based on the characteristics or content of the receiver terminal 420 . As a more specific example, when the operator of the receiver terminal 420 sets the receiver terminal 420 based on the food industry, related contents may be set based on related information. Referring to FIG. 4B , the related content may be set to any one of order-related, consultation-related, and business hours-related. However, this is only one example, and related content may be set in various ways, and is not limited to the above-described embodiment. Also, as an example, when the operator of the receiver terminal 420 sets the receiver terminal 420 based on health-related business, related content may be set based on related information. Referring to FIG. 4C , the related content may be set to any one of sports related, counseling, business hours, and visit method related. However, this is only one example, and related content may be set in various ways, and is not limited to the above-described embodiment. Also, as an example, when the operator of the receiver terminal 420 sets the receiver terminal 420 based on sales related to product sales, related content may be set based on related information. Referring to FIG. 4D , the related content may be set to any one of shopping item related, consultation related, and business hours related. However, this is only one example, and related content may be set in various ways, and is not limited to the above-described embodiment.

That is, as described above, related contents may be determined based on the characteristics and contents of the recipient terminal 420 , and specific related contents among a plurality of related contents are based on consultation between the sender terminal 410 and the recipient terminal 420 . can be decided. As an example, referring to FIG. 4A , the receiver terminal 420 provides a plurality of related content information in an automatic response, and the sender terminal 410 determines specific related content and provides the corresponding information to the receiver terminal 420 . can Thereafter, the receiver terminal 420 may transmit the determined related content information to the AI server 430 . In this case, the AI server 430 may process each of the related contents as separate existing or integrated related contents, and is not limited to the above-described embodiment. However, since the AI server 430 can check the response to the inquiry request of the caller terminal 410 based on the determined information based on the related content, the information processing time may be reduced. Then, the sender terminal 410 provides a query based on the determined related content to the receiver terminal 420, and the receiver terminal 420 responds to the query through the AI server 430 based on the query from the sender terminal 410. A response may be obtained and provided, and a specific method may be the same as that of FIG. 3 .

5 is a diagram illustrating a method of providing a VARS service using circuit switching according to an embodiment of the present specification.

As described above, the user terminal as the calling terminal may receive the VARS service through the voice call connection to the operator terminal as the recipient terminal, as described above. In this case, as an example, a case in which a plurality of user terminals make a call to the phone number of one operator terminal may be considered. The user terminal may make a call to the operator terminal through the above-described existing line.

That is, when one user terminal performs a call with the operator terminal, the corresponding user may be provided with the above-described VARS service, but since a dedicated line is established, other user terminals may not be able to connect to the operator terminal.

In consideration of the above, in a state in which a voice call is in progress between the first caller and the operator's terminal, the second caller may also be able to connect the operator's terminal with the voice call. In this case, as an example, the VARS server may provide a VARS service to a later caller by providing an Internet phone line to the operator terminal. Also, as an example, in the following description, line switching for a later caller will be described based on a case in which the first caller performs a call with the operator terminal, but the present invention may not be limited thereto.

That is, even when the line caller and the operator's terminal are not on a call, line switching may be performed based on the Internet telephone line based on the following method, and the present invention is not limited to the above-described embodiment.

Here, the VARS server may have one or more Internet telephone lines (e.g. 070, etc.) and may establish a network for these telephones through a local network. That is, the VARS server may subscribe to one or more Internet phone lines based on a telecommunication company and perform maintenance on the subscribed Internet phone lines. In this case, when the operator terminal is on a call based on the existing line, the VARS server may convert the voice call connection to the caller to the Internet phone line after an incoming call to the operator terminal, and provide the VARS service based on this.

For example, the VARS server may manage an Internet phone line corresponding to each operator's terminal. As a specific example, when the operator terminal 1 uses the Internet telephone lines 070-1 and 070-2 and the operator terminal 2 uses the Internet telephone lines 070-3 to 070-6, the VARS server uses the Internet for the corresponding operator terminals. You can own and manage phone lines, and through this you can provide services. This will be described later.

As a more specific example, referring to FIG. 5 , user terminal 1 510 may attempt a voice call connection to operator terminal 1 530 based on an existing line (e.g. PSTN). In this case, the operator terminal 1 530 may perform a voice call connection through an existing line and provide a VARS service to the user terminal 1 510 . That is, the existing line of the operator terminal 530 may be in a call state based on the user terminal 1 510 . Here, the VARS server 540 may provide the data connection VARS to the user terminal 1 510, which may be the same as in FIGS. 3 and 4 described above.

In this case, as an example, the user terminal 2 520 may attempt a voice call connection to the operator terminal 1 530 using an existing line. However, operator terminal 1 530 cannot connect to user terminal 2 520 because the voice call is being used, and accordingly, the VARS server 540 does not provide the VARS service to user terminal 2 520. may not be

Here, the operator terminal 1 530 may confirm the origination of the user terminal 2 520 , and transmit a telephone line switching request for this to the VARS server 540 . For example, as described above, the VARS server 540 may manage and maintain an Internet phone line for the operator terminal. The VARS server, which has received the phone line switch request from the operator terminal 1 530, searches the database for an Internet phone line number corresponding to the operator terminal 1 530, and based on this, the Internet that the operator terminal 1 530 can use. The phone line number may be notified to the operator terminal 1 (530). Thereafter, the operator terminal 1 530 may switch the line of the user terminal 2 520 to the Internet telephone line through the Internet telephone line 550 based on the notification of the VARS server 540 . That is, the user terminal 520 may be connected to the operator terminal 1 530 through the switched Internet phone line, and since it is packet-based communication, connection may be possible. Thereafter, the VARS server 540 may check the connection of the user terminal 2 520 and provide a data connection VARS service, which may be the same as in FIGS. 3 and 4 described above.

As another example, the operator terminal 1 530 may receive a call connection from an additional user terminal other than the user terminal 2 520 . That is, the operator terminal 1 530 may receive a call connection from a plurality of user terminals in a call connection state. At this time, the VARS server 540 performs a telephone line change using another telephone line among the Internet telephone lines of the operator terminal 1 530 based on the request of the operator terminal 530, and provides a data VARS service based on this. can do. That is, a plurality of Internet telephone lines for the operator terminal 1 530 may be set, and the VARS server 540 may provide a VARS service to a plurality of user terminals based on the plurality of Internet telephone lines. In this case, as an example, the VARS server 540 may set the number of Internet telephone lines for each operator terminal. Here, the VARS server 540 may set the initial number of Internet phone lines for each operator terminal and then monitor the frequency of use of the Internet telephone lines of the operator terminals. For example, when the call volume of the operator terminal is large and duplicate calls occur a lot, the number of Internet phone lines for the operator terminal may be increased. On the other hand, when the call volume of the operator's terminal is small and the current number of Internet telephone lines is unnecessarily large, the number of Internet telephone lines can be reduced.

Here, the increase or decrease in the number of Internet phone lines may be determined by comparing the actual call volume with a preset value for a preset period, and may be changed at regular intervals. Also, as an example, when triggering for telephone line adjustment occurs based on the VARS server, the number of Internet telephone lines for each operator terminal may be adjusted, and the embodiment is not limited thereto.

6A and 6B are diagrams illustrating a method of determining a line to be switched based on a predetermined condition according to an embodiment of the present specification. As described above, the VARS server can set up a plurality of Internet phone lines to the operator terminal, and can provide the VARS service through this.

Here, referring to FIG. 6A , the VARS server 620 may set the Internet phone lines to be switched for each outgoing time set in advance, respectively. That is, the VARS server 620 may adjust the switched Internet phone line based on preset time information. For example, the VARS server 620 may switch to the Internet telephone line A during business hours in consideration of the business hours of the operator terminal 610 . On the other hand, it may be set to switch to Internet phone line B for outgoing calls. As another example, in the case of a call outside business hours, it is not connected to the existing line (e.g. PSTN) of the operator's terminal, but is switched to the Internet telephone line regardless of whether a call is in progress, and it may be possible to provide a data connection VARS service, Through this, it is possible to control the use of the existing line by the operator's terminal.

Here, as an example, the VARS server 620 may set different VARS services provided for each of the Internet telephone line A and the Internet telephone line B. That is, it is possible to provide information on menus and reservations, etc. for phone line A during business hours, and information on whether business is closed or business hours guidance for phone line B can be provided. That is, the VARS server 620 may control the VARS service provided by separately managing the line.

As another example, referring to FIG. 6B , the VARS server 620 may set up an Internet phone line for each target of the caller terminal.

For example, the VARS server 620 uses the Internet telephone line A for the user terminals 630-1, 630-2, and 630-3 in the group A, and the user terminals 640-1 and 640-2 in the group B. , 640-3) can use Internet telephone line B. For example, since the number of Internet telephone lines that the VARS server 620 can provide may be limited, different Internet telephone lines may be used for each group.

As another example, each group may be determined based on location information. Here, as an example, for a group that is far from the operator terminal 610 and difficult to guarantee QoS, a phone line with excellent quality among Internet phone lines is allocated, and for a group that is close and easy to guarantee QoS, the quality is relatively low. can be assigned a lower phone line. That is, the VARS server 620 may select a phone line through which service is easy to provide in consideration of location information of user terminals in consideration of smooth service provision.

As another example, each group may be set in consideration of a relationship with the operator terminal 610 . For example, each group may be divided into a group in which a visit to the operator terminal 610 or an existing call is performed, and a group in which a connection to the operator terminal 610 is attempted for the first time. In this case, the VARS server 620 may be able to provide different services based on different phone lines, and is not limited to the above-described embodiment.

7A and 7B are diagrams illustrating a method of determining a switched line based on a service type according to an embodiment of the present specification. As another example, referring to FIGS. 7A and 7B , when the user terminal 710 and the operator terminal 720 switch Internet phone lines based on a call, different phone lines are established based on the type of service provided. can be used For example, a database 730 - 1 may exist in the VARS server 730 . In this case, in the VARS server 730, the Internet line switching may be performed according to the set state of the operator terminal 720 by grouping by service type (e.g. reservation, order, consultation, end of business guidance). As an example, in consideration of the case where the user terminal 710 wants to check reservation information, the VARS server 730 allocates a telephone line A and a telephone line B and provides it to the operator terminal 720, and provides a VARS service based on this. can provide In addition, each phone line can be set for different service types, and through this, a phone line differentiated for each service type is used, thereby improving phone line management efficiency.

Also, as an example, FIG. 8 is a diagram illustrating a method of sharing a line according to an embodiment of the present specification.

Referring to FIG. 8 , based on the database 810 of the VARS server, a phone line may be managed for each operator's terminal, as described above. In this case, as an example, the database 810 may manage Internet phone numbers matched for each operator terminal based on a table or list. That is, there may be a table or list of telephone lines for each operator's terminal. The VARS server may check the table or list based on the request of the operator terminal, and select and provide a phone line for the operator terminal so that the operator terminal can use the Internet telephone line. Here, the VARS server manager may provide a service by keeping both the above-described operator terminal and the Internet phone terminal in one place. That is, the database may flexibly manage Internet phone lines, and may not allocate only a specific phone line to a specific operator terminal.

As an example, in FIG. 8 , a case in which phone lines A and B are allocated to operator terminal 1 820 and telephone lines C and D are allocated to operator terminal 2 830 may be considered. Here, the database 810 may consider a case in which the operator terminal 820 needs to use the telephone line in addition to the telephone line A and the telephone line B in a state in which it is used. In consideration of the above-described case, the database 810 may connect each phone line through a local network. That is, each of the telephone lines can be used interchangeably. For example, when the operator terminal 1 820 requires an additional telephone line for the telephone line A and the telephone line B, the database 810 may store the telephone line C or the telephone line D of the operator terminal 2 830 based on the local network. can be used to provide the VARS service with the user terminal to the operator terminal 1 820, thereby increasing the efficiency of using the phone line.

As another example, the database 810 may manage an Internet telephone line table for a plurality of service types (service categories) with respect to the operator terminal. In this case, the database 810 may guide the Internet phone line switching to be performed based on the connection service setting of the operator terminal. Through this, the database 810 can increase the efficiency by measuring the usage time or frequency for each service type and flexibly performing a new Internet phone line subscription or cancellation.

Also, as an example, the database 810 may check the Internet phone line conversion rate for each operator based on the aforementioned phone line. For example, the database 810 may check billing information for each user based on the Internet phone line conversion rate for each operator, and may provide billing information for each operator terminal based on this, and may perform billing through this.

As another example, in the above-described embodiment, a case in which the operator terminal is in a call with another user terminal has been considered, but the present invention may not be limited thereto. As an example, the operator terminal may be assigned a plurality of phone numbers. In this case, the operator terminal may perform a voice call connection for a specific phone number based on an existing line (e.g. PSTN).

On the other hand, the operator terminal may make a request to the VARS server for another phone number and perform switching to the Internet phone line. That is, the operator terminal can designate a phone number to be switched to the Internet phone line and register it in the VASR server, and through this, the operator terminal line can be managed.

As another example, FIGS. 9A and 9B are diagrams illustrating a method of providing different services for each line according to an embodiment of the present specification. As described above, the operator terminal may be assigned a plurality of phone numbers. In this case, the user terminal 910 may check the phone number of the operator terminal when making a call to the operator terminal. Here, the operator terminal may separately provide the user terminal 910 with a phone number for attempting a voice call connection based on an existing line and a phone number for providing a VARS service based on data VARS. That is, the user terminal 910 may check each phone number and receive a desired service. For example, referring to FIG. 9A , the user terminal 910 may select a phone number for performing voice call connection based on the operator terminal and the existing line, and based on this, the user terminal 910 may perform the voice call connection through the existing line. have.

As another example, referring to FIG. 9B , the user terminal 910 may select another phone number of the operator terminal when receiving the VARS service for the operator terminal, and based on this, a data VARS service through the VARS server may be provided, but may not be limited to the above-described embodiment.

As another example, when a business operator is assigned a plurality of phone numbers, a specific phone number may not be connected to the VARS server. That is, operators can use it individually. On the other hand, a specific phone number can be connected to the VARS server so that the VARS service can be provided as described above, thereby increasing the efficiency of number use of the operator's terminal.

10 is a diagram illustrating a method of providing a visible ARS using circuit switching according to an embodiment of the present specification.

Referring to FIG. 10 , the operator terminal may perform a voice call connection with the user terminal using an existing line (S1010). In this case, the existing line may be a line using a dedicated line based on the above-described PSTN. Next, the operator terminal may provide the data-based visible ARS to the user terminal through the visible ARS server based on the existing line. (S1020) At this time, the visible ARS server is the data-based visible ARS to the user terminal connected through the existing line. It may be a server that provides Next, the operator terminal may receive a voice call request based on the existing line from another user terminal. (S1030) At this time, as described above, the existing line is a dedicated line and other user terminals do not connect with the operator terminal. can't Accordingly, the operator terminal may transmit a circuit switch request to the visible ARS server. In this case, the visible ARS server may select a specific Internet phone line from among a plurality of Internet phone line information based on the line switching request and provide the information to the user terminal. It is possible to provide the ARS service visible through the Internet phone line selected from the ARS server visible to the terminal (S1050).

Here, for example, as described above, in the existing line, only one terminal pair may be available through the leased line. That is, other user terminals cannot be connected while the operator terminal is in a call. On the other hand, the Internet telephone line may be a line in which a plurality of terminal pairs can be used based on a packet.

Also, as an example, the visible ARS server may build a database including a plurality of line information corresponding to the operator terminal. In this case, when the visible ARS server receives the line switching request from the operator terminal, it can check information on a plurality of lines corresponding to the operator terminal in the database, and select an Internet phone line provided to the operator terminal.

In this case, for example, the Internet phone line provided to the operator terminal through the visible ARS server may be determined based on the time at which the operator terminal receives a voice call request from another user terminal. As a specific example, when the operator terminal receives a voice call request from another user terminal in the first time period (or a specific time period), the visible ARS server selects the first type of Internet phone line and provides it to the operator terminal. have. On the other hand, when the operator terminal receives a voice call request from another user terminal in the second time period (or a specific time period), the visible ARS server may select the second type of Internet phone line and provide it to the operator terminal. That is, the visible ARS server may switch to a different Internet phone line based on time information set in the operator terminal.

Also, as an example, the Internet phone line provided to the operator terminal through the visible ARS server may be determined based on group information including other user terminals. For example, when another user terminal is included in the first group, the visible ARS server may select the first type of Internet phone line. On the other hand, when another user terminal is included in the second group, the visible ARS server may select the second type of Internet phone line. That is, the visible ARS server may switch to a different Internet phone line based on group information of the user terminal set in the operator terminal.

As another example, the Internet telephone line provided to the operator terminal through the visible ARS server may be determined based on the service type for the operator terminal. For example, when the operator terminal provides the first type service (e.g. reservation, consultation, etc.) to the user terminal, the visible ARS server may select the first type of Internet phone line. On the other hand, when the operator terminal provides the second type service (e.g. reservation, consultation, etc.) to the user terminal, the visible ARS server may select the second type of Internet phone line. That is, the visible ARS server may switch to a different Internet phone line based on group information of the user terminal set in the operator terminal.

As another example, a plurality of phone numbers may be set in the operator terminal. In this case, the operator terminal may use a specific phone number as a number for rejecting the user terminal's response without performing a line switch request, and may use a specific phone number to enable line switching as described above.
