Message Sending IVR System and Message Sending IVR Program

Abstract

To provide an automatic telephone answering system that reduces the cost of sending messages while reducing the burden on operators to respond to telephone calls by sending messages when a customer selects not to send a message or when the call is interrupted in an automatic telephone answering process. [Solution] The message sending IVR system performs audio playback processing during a call with a telephone caller, and includes a call end determination unit during audio playback that determines whether the caller has ended the call while the audio is being played back, and a call end determination unit during standby that determines whether the caller has ended the call while the signal standby unit is waiting for a DTMF signal or audio.If the call end determination unit during audio playback determines that the caller has ended the call while the audio is being played back by the audio playback unit, or if the call end determination unit during standby determines that the caller has ended the call while the signal standby unit is waiting for a DTMF signal or audio, and if it determines that the caller's telephone number is a mobile phone number, it sends a message to that mobile phone number.

Description

[Technical Field]

[0001] The present invention relates to a technology for automatically sending a message in a system that automatically responds to incoming calls. [Background technology]

[0002] In recent years, an increasing number of businesses are using automated IVR systems to handle calls from customers. This function can also play voice guidance to customers who are calling, prompt them to send DTMF signals by operating their telephones, and send messages in response to the DTMF signals sent. These functions are expected to reduce the burden on operators in handling calls.

[0003] However, with these automated telephone answering systems, a certain number of customers do not follow the voice guidance and end the call without sending a DTMF signal. Also, customers may send DTMF signals that do not lead to message transmission. If a customer chooses not to send a message or hangs up the call, the message is not sent, so the operator must call back, which places a burden on the operator, creating an issue.

[0004] The following technologies are known for systems related to message sending IVR. Patent Document 1 discloses a system that automatically responds with a voice message when a call is made to a specific phone number, and sends a specific message in response to receipt of specific number information within a specific period after the call. Patent Document 2 discloses a system that automatically sends an SMS email to the other party. [Prior art documents] [Patent documents]

[0006] However, these systems have various limitations because they are not designed to handle situations where a customer hangs up during an automated response. Specifically, messages are sent to callers who have successfully completed the incoming call flow, which can increase message sending costs. Also, there is no measure to prevent messages from being sent again after being sent during the incoming call flow, which can confuse customers.

[0007] To reduce the cost of sending messages while reducing the burden on operators to respond to telephone calls by sending messages when a customer selects not to send a message or when the call is interrupted in an automatic telephone answering process. [Means for solving the problem]

[0024] A message transmission IVR system 1 is connected to a caller terminal 2 via a communication network.

[0025] The communication network may be a telephone network, a dedicated line, a LAN (Local Area Network), the Internet, or a combination of these.

[0026] The call reception unit 11 responds to incoming calls from callers.

[0027] The voice reproducing unit 12 reproduces an automatic voice during a call.

[0028] The signal waiting unit 13 waits for a DTMF signal or voice from the caller during a call.

[0029] The processing information storage unit 14 stores the next processing to be executed for each received DTMF signal or voice information.

[0030] The telephone number determination unit 15 determines whether the telephone number of the caller is a mobile phone number.

[0031] The call end during voice reproduction determination unit 16 determines whether the caller has ended the call while the voice reproduction unit 12 is reproducing the voice.

[0032] The call end during standby determination unit 17 determines whether the caller has ended the call while the voice reproduction unit 12 is waiting for a DTMF signal or voice.

[0033] The message sending unit 18 for leavers sends a message to the mobile phone number when the call end determination unit 16 during audio playback determines that the caller has ended the call while audio is being played back by the audio playback unit 12, or when the call end determination unit 17 during standby determines that the caller has ended the call while the signal standby unit 13 is waiting for a DTMF signal or audio, and when the phone number determination unit 15 determines that the number is a mobile phone number.

[0034] The DTMF event message transmission decision unit 19 decides whether or not to send a message to the caller based on the DTMF signal or voice received during a call.

[0035] The message sending unit 20 for leavers with duplication prevention function sends a message to the mobile phone number when the call end determination unit 16 during audio playback determines that the caller has ended the call while audio is being played back by the audio playback unit 12, or when the call end determination unit 17 during standby determines that the caller has ended the call while the signal standby unit 13 is waiting for a DTMF signal or audio, and when the telephone number determination unit 15 determines that the number is a mobile phone number, and when the DTMF reason message sending determination unit 19 determines that a message should not be sent. (First embodiment: message transmission system)

[0036] An example of message transmission by the message transmission IVR system 1 when the signal waiting unit 13 receives a DTMF signal will be shown below.

[0037] FIG. 2 is a flowchart showing the processing of the message transmission IVR system 1 in the first embodiment.

[0038] The call receiving unit 11 puts the call from the caller into "on-call" status.

[0039] The voice playback unit 12 plays an automated voice message during the call: "Thank you for calling. This is Company A. If you have any questions about XX, press 1. For other inquiries, press 2."

[0040] The signal waiting unit 13 waits for a DTMF signal from the caller during a call.

[0041] FIG. 3 is a diagram showing information stored in the processing information storage unit 14 in the first embodiment.

[0042] The processing information storage unit 14 stores the following for the received DTMF signal "1": "Play the voice "Sending SMS" and then hang up"; and for the received DTMF signal "2": "Play the voice "We are currently busy. Please call again later" and then hang up."

[0043] The following describes the process when the signal waiting unit 13 receives a DTMF signal "1" from the caller and then the caller hangs up during voice playback.

[0044] The processing information storage unit 14 determines that the next processing is to "play back the voice message 'SMS will be sent' and then end the call."

[0045] The voice reproducing unit 12 reproduces the voice "SMS will be sent."

[0046] If the caller ends the call while the audio playback unit 12 is playing back audio, the audio playback end determination unit 16 holds the "call in progress" status.

[0047] The processing information storage unit 14 determines "send message" as the next processing.

[0048] The DTMF reason message transmission determining unit 19 holds "message transmission".

[0049] If the DTMF reason message transmission determining unit 19 holds "send message", the duplicate prevention function equipped message transmitting unit 20 for leavers does not transmit a message to the caller.

[0050] This embodiment may be modified so that if DTMF cannot be received, the call is hung up after a certain period of time, and in this case a message is sent to the mobile phone number in the same way as when the caller hangs up.

[0051] This embodiment may also be modified so that if the same caller calls multiple times within a certain period of time, no message is sent to the mobile phone number except the first time.

[0052] An example of the second embodiment of the present invention will be described below. (Example: Second embodiment)

[0053] FIG. 4 is a diagram showing the configuration of a message transmission IVR system 1 according to the second embodiment.

[0054] A message sending IVR system 1 is connected to a caller terminal 2 via a communication network.

[0055] The message sending IVR system 1 includes a call receiving response unit 11, a voice playback unit 12, a signal waiting unit 13, a processing information storage unit 14, a telephone number determination unit 15, a call termination determination unit 16 during voice playback, a call termination determination unit 17, a block list telephone number storage unit 111, a block list telephone number determination unit 112, and a message sending unit 113 for leavers with a function for determining whether or not to send a message.

[0056] The block list telephone number storage unit 111 stores a list of telephone numbers to which messages are not to be sent.

[0057] The block list telephone number determination unit 112 determines whether the telephone number of the caller is included in the list of telephone numbers held in the block list telephone number holding unit 111 .

[0058] The message sending unit 113 for leavers with no-transmission determination function sends a message to the mobile phone number when the call end determination unit 16 during audio playback determines that the caller has ended the call while audio is being played back by the audio playback unit 12, or when the call end determination unit 17 during standby determines that the caller has ended the call while the signal standby unit 13 is waiting for a DTMF signal or audio, and when the phone number determination unit 15 determines that the number is a mobile phone number and when the block list phone number determination unit 112 determines that the number is not included. (Second embodiment: message not sent)

[0059] An example of processing performed by the message sending IVR system 1 when no message is sent will be described below.

[0060] FIG. 5 is a flowchart showing the processing of the message transmission IVR system 1 in the second embodiment.

[0061] The call receiving unit 11 puts the call from the caller into "on-call" status.

[0062] The voice playback unit 12 plays an automated voice message during the call: "Thank you for calling. This is Company A. If you have any questions about XX, press 1. For other inquiries, press 2."

[0063] The signal waiting unit 13 waits for a DTMF signal from the caller during a call.

[0064] The processing information storage unit 14 stores "the voice 'We will call you back later' and then hang up" for the received DTMF signal "1", and stores "the voice 'We will call you back later' and then hang up" for the received DTMF signal "2".

[0065] The following describes the process when the caller hangs up while waiting for a DTMF signal from the caller or while the voice playback unit 12 is playing back voice.

[0066] The telephone number determination unit 15 determines whether the telephone number of the caller is a mobile phone number, and if so, stores the "mobile phone number."

[0067] The call termination during voice reproduction determination unit 16 determines whether the caller has ended the call while the voice reproduction unit 12 is reproducing the voice, and if the caller has ended the call while the voice is being reproduced, the "call in progress" status is maintained.

[0068] The call end during standby determination unit 17 determines whether the caller has ended the call while the signal standby unit 13 is waiting for a DTMF signal, and if the caller has ended the call while waiting, the "call in progress" state is maintained.

[0069] FIG. 6 is a diagram showing information stored in the block list telephone number storage unit 111 in the second embodiment.

[0070] The block list telephone number storage unit 111 stores the telephone number "08000000000" to which messages are not to be sent.

[0071] If the caller's telephone number "08000000000" is included in the list of telephone numbers stored in the block list telephone number storage unit 111, the block list telephone number determination unit 112 stores "block".

[0072] The message sending unit 113 for leavers with transmission unnecessary determination function does not send a message when the call end determination unit 16 during voice playback determines that the caller has ended the call while voice playback unit 12 is playing back voice, or when the call end determination unit 17 during standby determines that the caller has ended the call while signal standby unit 13 is waiting for a DTMF signal or voice, and even if the phone number determination unit 15 determines that the number is a mobile phone number, if the block list phone number determination unit 112 holds "blocked". [Industrial Applicability]

[0073] The present invention is a technology and program that automatically answers incoming calls and automatically sends messages according to the received DTMF signals and voice format. It can be used by companies that use telephones with DTMF or automated voice functions. [Explanation of symbols]
