Description

  The present invention relates to a server device that accepts an anonymous call request and an anonymous call method.

  For example, when dealing with mail order sales, it may be necessary to contact by telephone. In this case, the user notifies the sales company of the telephone number, makes a callback from the sales company, and contacts the establishment of the contract.

  On the other hand, if the user does not want to notify the sales company of the phone number, the user must make a phone call in order to contact the establishment of the contract (contract, cancellation) with the sales company. Don't be. For this reason, various proposals have been made that allow a user to keep a telephone number secret from a sales company and receive a callback from the sales company.

  For example, it has been proposed to conceal the telephone numbers of both the sender and the receiver so that a call can be made between the sender and the receiver to enable callback (see, for example, Patent Document 1).

  In addition, an intermediary device that anonymizes the phone number of the mobile terminal is installed between the mobile terminal and the broadcast station, and the intermediary device has a correspondence table between the user's phone number and the anonymized number, allowing anonymous calls and callbacks (For example, refer to Patent Document 2).

  Further, the connection ID of the first terminal that requests establishment of a communication connection, the content ID assigned to the content referred to by the first terminal, and the connection ID and content ID of the first terminal are associated with each other. By giving the given entry ID, it is possible to keep the communication terminal in a receivable state using the user's own connection ID that the user normally uses, conceal the identification information of the user terminal, and A communication connection method in which communication is performed anonymously has been proposed (see, for example, Patent Document 3).

  In addition, the caller registers the caller name in the exchange system in advance, and the exchange system notifies the caller name when there is a call, and calls the callee unless the caller notifies the caller address. A technique has been proposed that cannot be called back to a person (see, for example, Patent Document 4).

WO2002 / 049682 JP 2005-159485 A JP 2006-108768 A Japanese Patent Laid-Open No. 10-145355

  In technologies such as those described in Patent Documents 2 and 4, a temporary “anonymous phone number” may be obtained by a third party such as a stalker depending on the management status of the sales company. When a third party calls a user using an “anonymous phone number”, there is a problem that the user feels uncomfortable.

  In addition, when a specific user does not like the incoming call from the sales company and the association between the anonymous identifier and the telephone number of the specific user is canceled and the sales company is not notified, the other user sells the same anonymous identifier. When the company is notified, there is a problem that a call from a sales company to a specific user is received by another user.

  Further, in the techniques as described in Patent Documents 1 and 3, the “call terminal identifier” of the user is disclosed, and a third party obtains the “call terminal identifier” of the user from the server and sends it to the user. You can make anonymous calls. That is, there has been a problem that a call from a third party that the user does not like will be received by the user.

  An object of the disclosed server device is to avoid unnecessary incoming calls from a destination or a third party to which the user has made an anonymous call.

A server device according to an embodiment of the disclosure is a server device that receives an anonymous call request from a first communication device to a second communication device,
An anonymous call request from the first communication device is received, temporary identification information for the anonymous call request is generated, and identification information of the first communication device that is the transmission source and identification information of the second communication device that is the call destination And registration means for registering a set of the temporary identification information as a record in the identification information management table;
A transmission request in which the identification information of the first communication device that is the source of the anonymous transmission request from the first communication device is replaced with the temporary identification information registered in the identification information management table is transmitted to the second communication device. First transmission means.

  According to the present embodiment, it is possible to avoid unnecessary incoming calls to the user from a destination or a third party to which the user has made an anonymous call.

<First Embodiment>
<When calling from a user to a sales company using an anonymous phone number>
FIG. 5 is an explanatory diagram in the case of making a call from the user to the sales company with an anonymous telephone number, and FIG. 6 shows a sequence in the case of making a call from the user to the sales company with an anonymous telephone number. 5 and 6, the telephone terminal 11 having the telephone number 2000 performs an anonymous call operation (dialing by adding the prefix number abc before 3000) to the CRM system 12 having the telephone number 3000 of the sales company. Thereby, the telephone terminal 11 generates an anonymous outgoing connection request (Invite from: 2000, to: abc-3000), transmits it to the IP telephone network 10, and receives it by the SIP server 20.

  When the SIP server 20 receives the anonymous connection request (Invite), if the pair of the caller telephone number 2000 and the callee telephone number 3000 is not registered in the temporary telephone number management table 43a, for example, a temporary such as o123456 A phone number is generated, and a set of the caller phone number 2000, the callee phone number 3000, and the temporary phone number o123456 is additionally registered as one record in the temporary phone number management table 43a.

  FIG. 7 shows a first embodiment of the data configuration of the temporary telephone number management table 43a. Each record of the temporary telephone number management table 43a has a temporary telephone number (anonymous telephone number), a user telephone number (source telephone number), and an incoming call permitted telephone number (destination telephone number). ing. The temporary telephone number is a field in which a telephone number is notified from the user to the sales company as a caller number, and the telephone number used when a call operation is performed from the sales company to the user. The user telephone number is a field for storing the telephone number of the user's telephone terminal. The incoming call permission telephone number is a field for storing the telephone number of the sales company that has permitted the incoming call to the temporary telephone number by the user.

  Next, the SIP server 20 sends an outgoing connection request (Invite from: o123456) having the temporary telephone number (o123456) as the caller number to the telephone number 3000 of the sales company that is the destination of the anonymous connection request (INVITE). to: 3000) is generated and transmitted.

  As a result, the outgoing connection request (Invite from: o123456, to: 3000) with the sender number (o123456) is transmitted from the SIP server 20 and received by the CRM system 12 of the sales company with the telephone number 3000. Then, a response from the CRM system 12 is returned to the telephone terminal 11 via the SIP server 20, and a call between the user and the sales company is established. As a result, the user hangs up the telephone by informing the sales company of the conditions of the desired ticket, for example. In FIG. 6, the display of “200 response” will be described. The response in the 200s is a normal response. In addition, responses in the 100s represent provisional responses, and responses after 300 represent abnormal responses. This display is the same for other sequences.

  By the way, in the CRM system 12, the caller number of the outgoing connection request is o123456, which is different from the normal phone numbers 2000, 3000, etc., so that it can be determined that the caller number is a temporary phone number. Therefore, the CRM system 12 can clearly indicate on the screen display that the caller number is a temporary telephone number.

  FIG. 8 shows a flowchart of a first embodiment of processing executed when the control unit 44 of the SIP server 20 receives an anonymous call connection request having a special number abc. In FIG. 8, in step S <b> 1, the control unit 44 receives the incoming telephone number [to] = 3000 and the outgoing telephone number [from] = 3000 of the anonymous outgoing connection request (for example, Invite from: 2000, to: abc-3000). 2000 is extracted. In step S2, the control unit 44 searches the temporary telephone number management table 43a in the storage unit 43 for a pair of the destination telephone number [to] = 3000 and the transmission source telephone number [from] = 2000.

  The control unit 44 determines whether or not there is a retrieved record in the temporary telephone number management table 43a in step S3. If not, the control unit 44 generates a temporary telephone number (for example, o123456) that does not overlap with other records in step S4, and in step S5, the extracted destination telephone number [to] = 3000. And a caller telephone number [from] = 2000 and a temporary telephone number = o123456 are additionally registered as one record in the temporary telephone number management table 43a.

  On the other hand, if there is, the control unit 44, in step S6, sets the temporary telephone number (o123456) from the record that matches the destination telephone number [to] = 3000 and the transmission source telephone number [from] = 2000. Take out.

  After execution of step S5 or S6, the control unit 44 sends an outgoing connection request (Invite) with the temporary telephone number (o123456) as the caller number to the telephone number 3000 that is the destination of the anonymous connection request (INVITE) in step S7. from: o123456, to: 3000) is generated and transmitted.

<When sending from a sales company to users>
FIG. 9 is an explanatory diagram in the case of making a call from the sales company to the user, and FIG. 10 shows a sequence in the case of making a call from the sales company to the user. 9 and 10, the sales company dials the temporary telephone number (o123456) notified by the incoming call from the user in the CRM system 12 when the requirement from the user can be secured and makes a call. To do.

  As a result, an outgoing connection request (Invite from: 3000, to: o123456) destined for the temporary telephone number having the telephone number o123456 as the destination is transmitted from the CRM system 12 having the telephone number 3000 to the IP telephone network 10 and the SIP server 20 Received at.

  When the SIP server 20 receives the outgoing connection request addressed to the temporary telephone number (Invite from: 3000, to: o123456), the pair of the sender's telephone number 3000 and the recipient's temporary telephone number o123456 becomes a temporary telephone. It is searched whether it is registered in the number management table 43a.

  Here, a pair of the source telephone number 3000 and the destination temporary telephone number o123456 is obtained by the search, and the SIP server 20 sets the user telephone number 2000 corresponding to the temporary telephone number o123456 of the record obtained by the search. A call connection request (Invite from: 3000, to: 2000) is sent to the telephone terminal 11 having the telephone number 2000, which is the destination telephone number and the telephone number 3000 of the caller.

  The response from the telephone terminal 11 that has received the outgoing connection request (Invite from: 2000, to: 3000) is sent back to the CRM system 12 via the SIP server 20 to establish a call between the user and the sales company. Thereby, the sales company informs the user of the status of securing the ticket.

  FIG. 11 shows a flowchart of an embodiment of processing executed when the control unit 44 of the SIP server 20 receives an outgoing connection request addressed to a temporary telephone number (anonymous telephone number). 11, in step S11, the control unit 44 receives the temporary telephone number [to] = o123456 of the destination of the outgoing connection request (for example, Invite from: 3000, to: o123456) to the temporary telephone number, and the telephone number of the sender. [From] = 3000 is extracted. In step S12, the control unit 44 searches the temporary telephone number management table 43a in the storage unit 43 for a pair of the temporary telephone number [to] = o123456 of the destination and the telephone number [from] = 3000 of the transmission source.

  The control unit 44 determines whether or not there is a retrieved record in the temporary telephone number management table 43a in step S13. If not, the control unit 44 generates and transmits a connection failure response for the caller telephone number [from] = 3000 in step S14.

  On the other hand, if there is, the control unit 44 uses the destination from the record that matches the pair of the temporary telephone number [to] = o123456 of the destination and the telephone number [from] = 3000 of the source in step S15. The user's telephone number (2000).

  Thereafter, in step S16, the control unit 44 sends an outgoing connection request (Invite from: addressed to the user telephone number 2000, which is the destination of the outgoing connection request (INVITE)), to the sender telephone number (3000). 3000, to: 2000) is generated and transmitted.

<When making a call from the user to the sales company again>
FIG. 12 shows a sequence in the case where the user makes another call to the sales company using the anonymous telephone number. In such a case, the user changes the ticket requirements in a situation where the user is waiting for notification of the ticket securing status from the sales company.

  In FIG. 12, the telephone terminal 11 having the telephone number 2000 performs an anonymous call operation (dialing with the prefix number abc added in front of 3000) to the CRM system 12 having the telephone number 3000 of the sales company. Thereby, the telephone terminal 11 generates an anonymous outgoing connection request (Invite from: 2000, to: abc-3000), transmits it to the IP telephone network 10, and receives it by the SIP server 20.

  When the SIP server 20 receives the anonymous call connection request (Invite), the SIP server 20 searches the temporary phone number management table 43a with the pair of the caller telephone number 2000 and the callee telephone number 3000 to obtain a corresponding record.

  Next, the SIP server 20 sends an outgoing connection request (Invite from: o123456) with the temporary telephone number (o123456) as the caller number to the telephone number 3000 of the sales company that is the destination of the anonymous outgoing connection request (INVITE). , To: 3000).

  As a result, an outgoing connection request (Invite from: o123456, to: 3000) as the caller ID (o123456) is transmitted from the SIP server 20 and received by the CRM system 12 of the sales company with the telephone number 3000, and a response is made. The call between the user and the sales company is established. In the sales company, since the caller number is a temporary telephone number (o123456), it can be recognized that the call is from a user. As a result, the user can inform the sales company of desired requirements (change of conditions, etc.).

<When calling from a third party to the user>
The operation in response to an outgoing connection request in which a non-specified third party dials a temporary telephone number in a situation where the user is waiting for a notification of the ticket securing status from the sales company will be described using the sequence of FIG. . Here, it is assumed that the temporary telephone number can be obtained by an unspecified third party due to leakage from a sales company.

  In FIG. 13, an outgoing connection request (Invite from: 3001, to: o123456) having the temporary telephone number (o123456) as the destination is transmitted from the third party system having the telephone number 3001 to the SIP server 20.

  When the SIP server 20 receives the outgoing connection request addressed to the temporary telephone number (Invite from: 3001, to: o123456), the pair of the sender's telephone number 3001 and the destination temporary telephone number o123456 is changed to the temporary telephone. Since it is not registered in the number management table 43a, a connection rejection is transmitted to the unspecified third party system of the telephone number 3001. Thereby, the connection from the unspecified third party to the user becomes unsuccessful.

  In this way, it is possible to avoid unnecessary incoming calls from the receiving sales company or third party to which the user has made an anonymous call.

<When canceling anonymous phone number>
FIG. 14 shows a sequence when the user cancels the anonymous telephone number. This sequence is executed when the user refuses a callback from the sales company. In FIG. 14, the telephone terminal 11 having the telephone number 2000 performs an anonymous telephone number canceling operation (dialing by adding the prefix number xyz before 3000) to the telephone number 3000 of the sales company. As a result, the telephone terminal 11 generates an anonymous telephone number cancellation request (Invite from: 2000, to: xyz-3000), transmits it to the IP telephone network 10, and receives it by the SIP server 20.

  When the SIP server 20 receives the anonymous telephone number cancellation request (Invite), the SIP server 20 searches the temporary telephone number management table 43a with the pair of the telephone number 2000 of the caller and the telephone number 3000 of the callee, and temporarily stores the corresponding record. Delete from the general telephone number management table 43a.

  As a result, the SIP server 20 rejects the call to the user's telephone terminal 11 by the telephone number o123456 from the sales company having the telephone number 3000.

  FIG. 15 shows a flowchart of an embodiment of processing executed when the control unit 44 of the SIP server 20 receives a request to cancel a temporary telephone number (anonymous telephone number) having a special number xyz. In FIG. 15, the control unit 44 receives a temporary telephone number (anonymous telephone number) cancellation request (for example, Invite from: 2000, to: xyz-3000) at step S21, and receives the telephone number [to] = 3000 and Telephone number [from] = 2000 is extracted. In step S22, the control unit 44 searches the temporary telephone number management table 43a in the storage unit 43 for a pair of the destination telephone number [to] = 3000 and the transmission source telephone number [from] = 2000, and stores the record. Delete from the temporary telephone number management table 43a.

  Thereafter, in step S23, the control unit 44 generates and transmits a connection impossible response to the caller telephone number [from] = 2000.

<Sequence when the user only registers an anonymous phone number for the sales company>
FIG. 16 shows a sequence in the case of registering an anonymous telephone number from a user to a sales company (not making a call). In FIG. 16, the telephone terminal 11 having the telephone number 2000 performs an anonymous telephone number registration operation (dialing with the prefix number def added before 3000) to the CRM system 12 having the telephone number 3000 of the sales company. As a result, the telephone terminal 11 generates an anonymous telephone number registration request (Invite from: 2000, to: def-3000), transmits it to the IP telephone network 10, and receives it at the SIP server 20.

  When the SIP server 20 receives the anonymous telephone number registration request (Invite), if the pair of the caller telephone number 2000 and the callee telephone number 3000 is not registered in the temporary telephone number management table 43a, for example, o123456, etc. And a pair of the temporary telephone number o123456 of the caller telephone number 2000 and the callee telephone number 3000 is additionally registered as one record of the temporary telephone number management table 43a.

  Thereafter, for an anonymous call operation from the telephone terminal 11 of the user with the telephone number 2000 to the sales company with the telephone number 3000, a connection for notifying the temporary telephone number (in the example, o123456) as the caller number becomes possible. Further, by dialing a temporary telephone number (o123456) from a sales company having a telephone number 3000, an incoming call to the telephone terminal 11 of the user having the telephone number 2000 can be made.

  FIG. 17 shows a flowchart of an embodiment of processing executed when the control unit 44 of the SIP server 20 receives an anonymous telephone number registration request having a special number def. In FIG. 17, in step S31, the control unit 44 receives the destination telephone number [to] = 3000 and the source telephone number [from] = 3000 in the anonymous telephone number registration request (for example, Invite from: 2000, to: def-3000). 2000 is extracted. In step S32, the control unit 44 searches the temporary telephone number management table 43a in the storage unit 43 for a pair of the destination telephone number [to] = 3000 and the transmission source telephone number [from] = 2000.

  The control unit 44 determines whether or not there is a retrieved record in the temporary telephone number management table 43a in step S33. If not, the control unit 44 generates a temporary telephone number (for example, o123456) that does not overlap with other records in step S34, and in step S35, the extracted destination telephone number [to] = 3000. Then, the set of the sender telephone number [from] = 2000 and the temporary telephone number = o123456 is additionally registered as one record of the temporary telephone number management table 43a, and the process proceeds to step S36.

  On the other hand, if there is, the control unit 44 proceeds to step S36. In step S36, the control unit 44 generates and transmits an anonymous telephone number registration response to the telephone number [from] = 2000 of the caller.

<When notification of temporary phone number cancellation to sales company>
FIG. 18 shows a sequence in a case where a cancellation notification is made to the sales company when the user cancels the anonymous telephone number. This sequence is a modification of the sequence of FIG. In FIG. 18, the telephone terminal 11 having the telephone number 2000 performs an anonymous telephone number canceling operation (dialing by adding the prefix number xyz before 3000) to the telephone number 3000 of the sales company. As a result, the telephone terminal 11 generates an anonymous telephone number cancellation request (Invite from: 2000, to: xyz-3000), transmits it to the IP telephone network 10, and receives it by the SIP server 20.

  When the SIP server 20 receives the anonymous telephone number cancellation request (Invite), the SIP server 20 searches the temporary telephone number management table 43a with the pair of the telephone number 2000 of the caller and the telephone number 3000 of the callee, and temporarily stores the corresponding record. Delete from the general telephone number management table 43a. Further, a temporary telephone number (o123456) release notification is transmitted to the sales company with the telephone number 3000.
