That is, when there is a virtual number associated with the phone number of another user terminal included in the first call, the processor 334 is a second call communicable between the user terminal 210 and the internal communication device to which the virtual number is assigned. can create

According to an embodiment, the processor 334 may store the phone number of another user terminal in association with the virtual number of the internal communication device. For example, after allocating a specific virtual number to a specific internal communication device, the processor 334 may store the corresponding virtual number in a database by associating the corresponding virtual number with the phone number of a user using the corresponding internal communication device. Then, when the processor 334 determines whether a virtual number associated with a phone number of another user terminal exists among the plurality of virtual numbers, searches the corresponding database, and the virtual number associated with the phone number of another user terminal exists You can decide whether to do it or not.

4 is a diagram illustrating an exemplary database 400 in which a virtual number and a phone number of a user terminal are associated and stored according to an embodiment of the present disclosure. According to an embodiment, the database 400 may include a virtual number assigned to the internal communication device and a phone number of a user terminal corresponding to each virtual number. The database 400 may be constructed as an arbitrary data structure in which the representative number 410, the virtual number 420, the phone number 430 of the user terminal, and the like are stored in association with each other.

For example, the representative number 410 may be connected to an external communication network or an external communication system, and may be stored in association with or matched with each of the internal virtual numbers 420 . For example, 070-xxx-xxxx corresponding to the representative number 410 is matched or stored in association with 070-111-1111, 070-222-2222, 070-333-3333, etc., corresponding to the virtual number 420, respectively. can be In addition, the virtual number 420 refers to an arbitrary number allocated virtually, and may be a number for use in an independently established internal communication network within a specific business site. The virtual number 420 may be an arbitrarily assigned virtual phone number or a predetermined real phone number. For example, the virtual number 420 may be a real phone number or a virtual phone number associated with an Internet phone service. With such a configuration, when the virtual number 420 is configured as a virtual phone number, resources of the actual phone number can be saved, so that an internal communication network can be established so that a plurality of internal communication devices are connected.

The virtual number 420 may be stored in association with or matched with an actual phone number 430 of the user terminal. For example, virtual number 070-111-1111 is stored in association with phone number 010-1111-1111, virtual number 070-222-2222 is stored in association with phone number 010-2222-2222, and virtual number 070- 333-3333 may be stored in association with the phone number 010-3333-3333. Meanwhile, the representative number 410 and the phone number 430 of each user terminal may be connected to a call forwarding service. For example, when an arbitrary caller transmits a call to the phone number 430 of the user terminal, the call forwarded to the system having the representative number 410 may be received.

In FIG. 4 , it is illustrated that one representative number 410 is stored in association with the virtual number 420 on the database 400 , but the present invention is not limited thereto. For example, there may be two or more representative numbers capable of communicating with an external communication network or system of an external communication company, and each representative number may be stored in association with a plurality of virtual numbers. By using such a database 400, the information processing system can connect a call with the internal communication device of the other party intended by the user without directly receiving an extension number from the user through ARS or the like.

5 is a diagram in which a call is directly connected using call forwarding between the first user terminal 510, the communication company's system 520, the information processing system 530, and the internal communication device 540 according to an embodiment of the present disclosure. It is a drawing showing an example. According to an embodiment, the first user terminal 510 is a terminal of a caller and may refer to any device capable of transmitting and receiving a call.

Accordingly, the first call may include the phone number of the first user terminal 510 as the calling number and the representative number of the information processing system 530 as the receiving number.

The forwarded first call 524 may be transmitted to the information processing system 530 . The information processing system 530 that has received the first call 524 may extract the phone number of the second user terminal, which is the received number before the call is forwarded from the first call. Then, the information processing system 530 may determine whether a virtual number (eg, an extension number of an internal communication network, etc.) associated with the extracted second user terminal phone number exists. When the virtual number exists, the information processing system 530 includes the phone number of the first user terminal 510 as the calling number, and uses the phone number of the internal communication device 540 to which the virtual number is assigned as the receiving number. A second call may be created that includes ( 532 ).

The call forwarded second call 534 may be transmitted to the internal communication device 540 to which the corresponding virtual number is assigned. Accordingly, the internal communication device 540 may receive the second call ( 542 ). Then, when the user of the internal communication device 540 accepts the second call, a call that can be communicated between the first user terminal 510 and the internal communication device 540 may be connected ( 550 ). With this configuration, the user of the first user terminal 510 can conveniently make a call with the counterpart of the second user terminal without directly inputting the extension number or virtual number of the internal communication device 540 using ARS or the like. can be done

7 is a flowchart illustrating an example of a method 700 for connecting a virtual number based on double call forwarding according to an embodiment of the present disclosure. According to an embodiment, the virtual number connection method 700 based on double call forwarding may be performed by an information processing system (eg, at least one processor of the information processing system). The double call forwarding-based virtual number connection method 700 may be initiated by the processor receiving the first call with the phone number of the first user terminal as the calling number and the representative number as the receiving number (S710). For example, the processor may receive the first call to which the phone number of the second user terminal is forwarded to the representative number.

According to an embodiment, the processor may extract the phone number of the second user terminal connected to the call forwarding based on the received first call (S720). That is, the first call may include the phone number of the second user terminal first input on the first user terminal. Accordingly, the processor may extract the phone number of the second user terminal corresponding to the received number before the call forwarding is performed from the first call.

Then, the processor may determine whether there is a virtual number associated with the extracted second user terminal's phone number from among the plurality of virtual numbers (S730). When it is determined that the virtual number associated with the phone number of the second user terminal exists, the processor may generate a second call connecting the phone number of the first user terminal and the virtual number by using call forwarding (S740). ). In addition, the processor may transmit the generated second call to the internal communication device associated with the virtual number (S750). When the user associated with the internal communication device that has received the second call receives the call, a communicable call may be connected between the first user terminal and the second user terminal and the corresponding internal communication device.

8 is a flowchart illustrating an example of a method 800 for determining whether a virtual number exists according to an embodiment of the present disclosure. According to an embodiment, the virtual number presence determination method 800 may be performed by an information processing system (eg, at least one processor of the information processing system). The virtual number existence determination method 800 may be started by determining whether a virtual number corresponding to the phone number of the user terminal extracted from the forwarded call exists (S810). In this case, the same method as described above may be used for receiving the forwarded call and extracting the phone number of the user terminal from the forwarded call.

When it is determined that there is a virtual number corresponding to the phone number of the user terminal, the processor may generate a second call connecting the phone number of the first user terminal and the virtual number by using call forwarding (S820). In this case, as described above, the processor may transmit the generated second call to the internal communication device associated with the virtual number (S830).

On the other hand, if it is determined that the virtual number corresponding to the phone number of the user terminal does not exist, the processor may reject the call signal (S840). For example, when the virtual number is not searched for in the database previously created by the user, the processor may determine that the virtual number corresponding to the phone number of the user terminal does not exist. As such, when the processor rejects the call signal, the procedure of the method 800 for determining whether a virtual number exists may be terminated.
