Description

The present invention relates to a telephone communication information analysis method capable of analyzing telephone communication between a user and a customer without significantly improving the existing telephone equipment configuration.

Examples of means for advertising their products / services include posting on various advertising media such as the Internet, TVCM, and paper media (free paper, newspapers, magazines, flyers, etc.).
There is a need for advertisers to evaluate which advertising media is most efficient in terms of cost effectiveness.
Therefore, it is conceivable to obtain a telephone number for each of a plurality of advertising media and evaluate the advertisement effect from the incoming call history. However, it is necessary to prepare a telephone for each telephone number and make various settings, which increases costs. There's a problem.
Therefore, in Patent Document 1, an affiliate ID unique to the site is attached to an advertisement link of a plurality of websites on which the company's advertisement is posted, and the customer terminal that clicks the advertisement link together with various information such as a telephone number. A system is disclosed in which a user (advertiser) can know which advertisement posting site has received a call by transmitting an affiliate ID to the management server together (Patent Document 1 [0029]). reference).
There is also a system in which a PBX (Private Branch eXchange) or an IP-PBX (Internet Protocol Private Branch eXchange) is separately prepared outside the office of the user (advertiser), and the advertising effect can be measured for each telephone number.

JP 2009-75974

  However, the technology of the above-mentioned Patent Document 1 is an evaluation method that can be applied to web advertisements on the Internet, and when advertising is posted on various media including TVCM and paper media as described above, There is a problem that the number of incoming calls from users via the media cannot be counted to evaluate the advertising effectiveness.

In addition, in a system that separately prepares a PBX or IP-PBX outside the office, once the call is received at the PBX or IP-PBX outside the office, it is automatically redirected to the telephone number that the office wants to receive the call. Therefore, there is a problem that a call charge is generated for the user of the system even though it is an incoming call.
Furthermore, the telephone number set in the PBX or IP-PBX outside the office is displayed on the telephone display in the office when an incoming call is received, so that the telephone number of the customer who made the call cannot be known. Although the missed call history is displayed, there is a problem that it is not known whether the user has made a return call to the customer.

  In some cases, IP phone handsets are directly connected via the Internet using IP-PBX. In this case, the problem that the call charge is generated despite the above-described incoming call and the problem that the user cannot know the telephone number of the customer are solved. However, it is necessary for the user to separately prepare an IP telephone cordless handset corresponding to the IP-PBX, and it is not possible to cope with the existing telephone equipment environment, resulting in a problem that the cost of system construction increases.

For the user (advertiser), not only the number of incoming calls by phone number but also whether the operator actually answered the call when there was an incoming call, that is, there were many incoming calls at the same time, and the number of phone channels By checking the number of cases that could not be answered due to lack of phone numbers, the number of cases that could not be answered due to malfunctions such as the disconnection of the handset, and the time zone when such an unresponsive event occurred, it was confirmed whether there was a loss of response opportunity. There is a need to understand.
Furthermore, there is a need for the user to grasp the quality of telephone correspondence by knowing the time (calling time) from when an incoming call arrives until the operator answers the telephone.
However, with the above-described conventional technology, it is not possible to grasp the response period loss and telephone response quality that occur in such office premises.

In view of the above problems, an object of the present invention is to provide a telephone communication information analysis method capable of analyzing telephone communication between a user and a customer without greatly improving the existing telephone equipment configuration.

Telephone communication information analysis method of the present invention, in the telephony information analyzing method for analyzing a telephone communication information between the user and the customer performs advertisement effect analysis, which derives the analysis information, the advertisement effect analysis However, an advertisement link for accessing the user's website is displayed on the advertisement posting site, and the customer clicks the advertisement link from his / her external telephone terminal, and the advertisement link to the advertisement link by the click A second step of transmitting the assigned advertising job number and customer phone number data to the server; and a third step of storing the advertising job number and customer phone number data transmitted in the second step in the server. Then, the customer accesses the user's website by the click, and the fourth call is made to the user's telephone number displayed on the website. And the fifth step of transmitting the telephone number data of the user and the telephone number data of the customer to the server when the user receives from the customer, and the user transmitted in the fifth step in the server The phone number data of the customer and the phone number data of the customer are stored in the sixth step; the customer phone number data stored in the server in the third step and the customer phone number data stored in the sixth step It is characterized by comprising at least a seventh step for judging inconsistency .

According to the telephone communication information analysis apparatus and the telephone communication information analysis method of the present invention, by performing response opportunity loss analysis, analysis of the number of incoming and outgoing calls by telephone number, telephone correspondence quality analysis and advertisement effect analysis, the user and the customer Analysis of telephone communication between them can be performed.
In addition, when the telephone communication information analyzing apparatus of the present invention is placed between the ONU and IP-PBX (optical router, etc.) owned by the user, the user telephone number assigned by the contract with the telephone company (example: user's telephone number) The above analysis for all telephone numbers of incoming numbers received at the office can be performed without changing the existing telephone equipment configuration and existing environment.
In addition, installation of the telephone communication information analysis device can be completed simply by installing it between the ONU and the IP-PBX for the existing telephone equipment configuration and existing environment, so installation work can be completed in a short time and removal is also possible. (Restoring the current situation) can be completed in a short time without changing the existing telephone equipment configuration and existing environment.
In addition, even when a telephone number is added / deleted / changed according to a contract between the telephone company and the user, it is not necessary to consider the influence of the telephone communication information analysis device of the present invention, and after the addition / deletion / change Regarding the telephone number, the telephone communication information analyzing apparatus of the present invention can perform the above analysis.
In addition, in the advertisement effect analysis, when the customer's phone number data stored in the third step matches the customer's phone number data stored in the sixth step, the information is communicated to the user. Then, it can be seen that the customer accessed the user's website via the advertisement link displayed on the specific advertisement posting site, and actually called the user's telephone number. As a result, the user can confirm the effect of placing the advertisement on the advertisement posting site, so that the user and the operator of the advertisement posting site, and further the operation of the user and the advertisement posting site. Distribution of success fees based on success-reward-type advertisements (affiliates) and the like can be performed between a person and a customer.

Embodiments of a telephone communication information analyzing apparatus and a telephone communication information analyzing method according to the present invention will be described below with reference to the drawings.
For convenience of explanation, a person who uses the telephone communication information analyzing apparatus is denoted as “user”, and a person who makes a call to the user or receives a call from the user is denoted as “customer”. Then, transmission or reception of a telephone call by a user is expressed as “user transmission” or “user reception”, and transmission or reception of a telephone call by a customer is expressed as “customer transmission” or “customer reception”.

FIG. 1 shows an installation example of the telephone communication information analyzing apparatus 1.
The telephone communication information analysis device analyzes the telephone communication information when the user of this device receives an incoming call from the customer's external telephone terminal, and makes a call to the customer from the user's telephone terminal. ) Analyze the telephone communication information.
For example, in Fig. 1 (a), in the optical line telephone network, the customer's external telephone terminal 100 is the telephone company switch 101, the user's ONU (Optical Network Unit) 102, and the IP-PBX 103. A configuration connected to one or a plurality of telephone terminals 104 is shown. In this case, the telephone communication information analyzing apparatus 1 is installed between the ONU 102 and the IP-PBX 103.
FIG. 1 (b) shows a configuration in which an external telephone terminal 100 of a customer is connected to a plurality of extension telephone terminals 107 via a user's analog telephone terminal 105 or main device 106 in an analog telephone network. In this case, the telephone communication information analyzing apparatus 1 is installed between the two TCP-IP converters 108.
FIG. 1 (c) shows a configuration in which the customer's external telephone terminal 100 is connected to the user's IP phone 110 in the Internet network 109. In this case, the telephone communication information analyzing apparatus 1 is installed between the IP-PBX 103 and the IP telephone 110.
FIG. 1 (d) shows a configuration in which the customer's external telephone terminal 100 is connected to one or more telephone terminals 104 of the user in the Internet network 109. In this case, the telephone communication information analyzing apparatus 1 is installed between the two IP-PBXs 103.
1 (a) to 1 (d) are merely installation examples of the telephone communication information analyzing apparatus 1, and can be applied to other line configurations.

As shown in FIG. 2, the telephone communication information analyzing apparatus 1 is roughly composed of a storage unit 10, a control unit 20, a display unit 30, and an operation unit 40.
The storage unit 10 is used for storing telephone communication information.
The telephone communication information includes the telephone number of the external telephone terminal 100 (customer telephone number 100a), the user telephone number 50 transmitted by the external telephone terminal 100, the time of incoming call, the presence / absence of a response at the destination, and the calling time. Although at least one is mentioned, it is not limited to these.
In addition to the telephone communication information, the storage unit 10 also stores various programs for driving the telephone communication information analyzing apparatus 1.

The control unit 20 is constituted by, for example, a microprocessor, and is used for sequentially reading and executing various programs stored in the storage unit 10.
The control unit 20 reads out the telephone communication information stored in the storage unit 10 and analyzes it appropriately, so that at least one of response opportunity loss analysis, number of incoming / outgoing calls by telephone number, quality analysis for telephone correspondence, and advertisement effect analysis To derive analysis information. The analysis information analyzed by the control unit 20 is stored in the storage unit 10.
The display unit 30 is used to display analysis information analyzed by the control unit 20.

The flow of the telephone communication information analysis method of the present invention will be described below with reference to the drawings.
As shown in the flowchart of FIG. 3, the control unit performs response opportunity loss analysis (S101), analysis of the number of incoming / outgoing calls by telephone number (S102), quality analysis corresponding to telephone (S103), and advertisement effect analysis (S104).
Note that these four analyzes do not necessarily have to be performed in the order shown in FIG. Further, the above four analyzes may be performed simultaneously.
The user performs a predetermined operation on the operation unit, and displays necessary analysis information on the display unit from the storage contents of the storage unit. The user loses a response opportunity based on the analysis information, and the user telephone number. Understand the different number of incoming calls, telephone response quality, and advertising effectiveness.

Next, response opportunity loss analysis will be described with reference to the flowchart of FIG.
The control unit continues to acquire and analyze user and customer call logs (S201). If there is an incoming call from the user (“incoming” in S202), the response opportunity loss at the time of incoming call is analyzed (S203, FIG. 5), and if there is an outgoing call from the user (“outgoing” in S202) ), The presence or absence of a response opportunity loss at the time of user transmission is analyzed (S204, FIG. 6).

Next, a response opportunity loss analysis at the time of a user call will be described using the flowchart of FIG.
The control unit determines whether or not the incoming call is busy while acquiring / analyzing the incoming data such as the customer telephone number that is calling from the call log (S301). Here, “incoming call busy” means that the corresponding operator is busy (over channel number), the operator's handset is disconnected, the operator's telephone is broken, the number of telephones is insufficient, etc. This means that the ringing tone does not sound due to various circumstances.
If the incoming call is not busy (NO in S302), the control unit next determines whether or not the operator responds (S303).

When the operator responds (“YES” in S303), the control unit calls the response opportunity loss master stored in the storage unit. In the response opportunity loss master, the customer telephone number when the operator on the user side cannot respond due to some circumstances when the user has received a call in the past is recorded.
Then, the control unit matches the customer telephone number with the telephone number recorded in the response opportunity loss master (S304), and determines whether or not they match (S305). Here, the fact that the customer telephone number matches the telephone number recorded in the response opportunity loss master means that a customer who has failed to respond in the past has called the user again.

If they match (“YES” in S305), the control unit creates response opportunity loss recovery data (S306), updates the response opportunity loss master, and stores it in the storage unit (S307). In this case, the customer who failed to respond in the past made a call to the user again, and the loss of the response opportunity was recovered (the response opportunity was obtained) by answering the call on the user side. Means.
On the other hand, if they do not match (“NO” in S305), the control unit updates the response opportunity loss master and stores it in the storage unit (S307). In this case, this means that a customer who has no record of loss of response opportunity has made a call to the user and has answered the call on the user side.
On the other hand, if the incoming call is busy (“YES” in S302), the control unit creates response opportunity loss data (S308), updates the response opportunity loss master, and stores it in the storage unit (S307). In this case, it means that although the customer made a call to the user, he / she could not answer the call on the side of the user (it was unable to answer), and thus lost the response opportunity.
Similarly, when the operator does not respond (“NO” in S303), the control unit similarly creates response opportunity loss data (S309), updates the response opportunity loss master, and stores it in the storage unit (S307). .
This completes the analysis of the response opportunity loss when the user receives a call.

Next, response opportunity loss analysis at the time of user transmission will be described using the flowchart of FIG.
The control unit obtains outgoing data such as the customer telephone number that the user is calling from the call log (S401), calls the response opportunity loss master stored in the storage unit, and sets the customer telephone number. The telephone number recorded in the response opportunity loss master is matched (S402), and it is determined whether or not they match (S403). Here, the fact that the customer telephone number matches the telephone number recorded in the response opportunity loss master means that the user has made a call to the customer who has not responded in the past.

If they do not match (“NO” in S403), the control unit stores it in the storage unit as a simple user call (S407). Here, the disagreement means that the user is calling a customer who has never lost a response opportunity in the past.
On the other hand, if they match (“YES” in S403), it is determined whether the call is busy (S404). Here, calling busy means that the customer is busy (the number of channels is over), the customer's handset is disconnected, the customer's telephone is broken, or the number of telephones is insufficient. This means that the ringer does not ring.
If the call is not busy (“NO” in S404), the control unit next determines whether or not the customer responds (S405).

When the customer responds (“YES” in S405), the control unit creates response opportunity loss repair data (S406), updates the response opportunity loss master, and stores it in the storage unit (S407). In this case, it means that the user has made a call to a customer who has not responded in the past, and that the lost state of the response opportunity has been repaired (the response opportunity has been obtained) by the customer answering the call.
On the other hand, if the call is busy (“YES” in S404), the control unit creates response opportunity loss unrepaired data (S408), updates the response opportunity loss master, and stores it in the storage unit (S407). In this case, it means that although the user made a call to a customer who could not respond in the past, the customer side telephone was not connected, so the response opportunity loss state could not be repaired.
Similarly, if the customer does not respond even though the phone is connected (“NO” in S405), the control unit similarly creates response opportunity loss unrepaired data (S409) and updates the response opportunity loss master. To be stored in the storage unit (S407). In this case, since the customer did not answer the call (not responded), it means that the response opportunity loss state could not be repaired.
The response opportunity loss analysis at the time of user transmission is thus completed.

Next, the flow when the user grasps and repairs the situation of response opportunity loss using the telephone communication information analyzing apparatus will be described with reference to the flowchart of FIG.
When the user performs a predetermined operation on the operation unit, the control unit calls the response opportunity loss master stored in the storage unit and displays it on the display unit (S501).
Based on the content displayed on the display unit, the user makes a call to a customer who is in a response opportunity lost state (S502).
While acquiring the outgoing data (S503), the control unit performs the response opportunity loss analysis (S504) at the time of user outgoing as described in the flowchart of FIG. 6, and updates the response opportunity loss master according to the result to the storage unit. Remember.
After the call ends, the user performs a predetermined operation on the operation unit, displays the updated response opportunity loss master on the display unit (S505), and indicates that the response opportunity loss state has been repaired or has not been repaired. Grasp (S506) and end.
As described above, according to the present invention, it is possible to grasp not only the presence or absence of a response opportunity loss but also whether or not the user has repaired the response opportunity loss. In addition, when a customer makes a call to a customer who is in a lost response opportunity state several times, he / she gives up an interval to make a call so that the number of calls will not be excessive, or abandon the repair of lost response opportunity. It is also possible to take measures such as

Next, the analysis of the number of incoming / outgoing calls by telephone number will be described using the flowchart of FIG.
The control unit continues to acquire user and customer call logs (S601).
If there is an incoming call from the user (“incoming call” in S602), incoming data such as the telephone number of the customer who made the call and the telephone number of the user is acquired (S603) and stored in the storage unit ( S604).
On the other hand, when there is a call from the user (“call” in S602), call data such as the user's telephone number and the telephone number of the customer who is calling the user are acquired (S605) and stored in the storage unit. It is memorized (S604).
This completes the analysis of the number of incoming and outgoing calls by phone number.
The data stored in the storage unit is aggregated by the control unit when the user performs a predetermined operation on the operation unit, and the number of incoming / outgoing calls by user's phone number or by customer's phone number Is displayed on the display as the number of incoming / outgoing calls.

Next, the telephone response quality analysis will be described with reference to the flowchart of FIG.
The control unit continues to acquire user and customer call logs (S701).
If there is an incoming call from the user (“YES” in S702), the measurement of the calling time is started (S703).
The control unit waits until the operator responds (“NO” in S704 and “NO” in S705).
If the operator responds ("YES" in S704), the time (elapsed time) from the start of the call to the response (acquired time) is acquired as data with an incoming response (S706) and stored in the storage unit (S707).
On the other hand, if the operator does not answer (“NO” in S704) and the customer who has made the call hangs up (“YES” in S705), from the start of the call as data with no incoming response until the customer hangs up (Elapsed time) is acquired (S706) and stored in the storage unit (S707).

On the other hand, when there is a user call and a customer calls (“YES” in S702), measurement of the calling time is started (S703).
The control unit waits until the customer responds (“NO” in S704 and “NO” in S705).
When the customer responds (“YES” in S704), the time (elapsed time) from the start of the call to the response (acquired time) is acquired as data with an outgoing response (S706) and stored in the storage unit (S707).
On the other hand, if the customer does not answer (“NO” in S704) and the user who made the call hangs up (“YES” in S705), the user hangs up from the start of the call as no outgoing response data. Time (elapsed time) is acquired (S706) and stored in the storage unit (S707).
This completes the quality analysis for telephone support.

Next, the advertisement effect analysis will be described with reference to FIG. 10 and FIG.
First, it is assumed that a user (advertiser) who installs the telephone communication information analyzing apparatus 1 has a plurality of user telephone numbers 50 as a precondition. “Has multiple user phone numbers” means that the user has multiple lines and a telephone number is assigned to each line, or that the user is connected to a single line. This means a case where a plurality of telephone numbers are assigned to the telephone terminal. However, the present invention is not limited to these, and any telephone number may be used as long as the user can receive an incoming call from a customer and respond. Therefore, for example, it may be a mobile phone number owned by the user.

When a user places an advertisement on a plurality of advertisement media, the user himself / herself assigns a plurality of user telephone numbers 50 (50a to 50c) possessed by the user to the plurality of advertisement media on a one-to-one basis. For example, as shown in FIG. 10, the user telephone number 50a “00-000-000-0001” for the Internet web advertisement A, and the user telephone number 50b “00-000 000” for the free paper B "--0002", user phone number 50c for magazine C, "user-00-00-0003", etc., are allocated and posted with different user phone numbers (step S801 in FIG. 11). .
A person who sees the advertisement transmits the user telephone number 50 described in the advertisement from his / her outside line telephone terminal 100. For example, the person who sees the free paper B transmits to the user telephone number 50b “OO-OOOO-0002”.

While acquiring / analyzing the call log (S802), the control unit 20 waits for an incoming call (S803), and when there is an incoming call (“YES” in S803), the operator of the external telephone terminal 100 The telephone terminal 104b corresponding to the transmitted user telephone number 50b “OO-OOOO-0002” responds.
The control unit 20 causes the storage unit 10 to store the user telephone number 50b “OO-OOOOOO-0002” as telephone communication information (step S804).
Similarly, the person O who sees the magazine C calls the user telephone number 50c “OO-OOOO-0003”, and the operator of the user responds at the telephone terminal 104c corresponding to the telephone number.
The control unit 20 causes the storage unit 10 to store the user telephone number 50c “OO-OOOO-0003” as telephone communication information (step S804). If the customer telephone number 100a is also known, it may be stored in the storage unit 10.

The user performs a predetermined operation on the operation unit 40 of the telephone communication information analyzing apparatus 1 after a certain period (for example, one month) has elapsed.
When the operation unit 40 is operated, the control unit 20 determines from the telephone communication information stored in the storage unit 10 all the user telephone numbers 50 (50a to 50c) transmitted from the customer's telephone terminal 100 within a certain period. The number of calls received for each user telephone number 50 (50a to 50c) is totaled, and the result is displayed on the display unit 30 as analysis information.
Thus, the advertisement effect analysis is completed (step S807).
Based on the displayed analysis information, the user grasps how many calls are made from the external telephone terminal 100 to each user phone number 50 (50a to 50c), that is, how many calls are received from each advertising medium. This evaluates the cost effectiveness for each advertising medium.

The telephone communication information analyzing apparatus 1 may be connected to a server on the Internet so that the user can grasp the number of incoming calls from any place such as a place where they are out.
In addition, the storage unit 10 and the control unit 20 are stored in the case of the telephone communication information analyzing apparatus 1, and the display unit 30 and the operation unit 40 are connected to the user's personal computer or information portable terminal by wired or wireless connection. You may decide to utilize the display part and operation part which are provided.

Next, another example of advertisement effect analysis will be described.
As shown in FIG. 12, the customer's external telephone terminal 100 is connected to the Internet network 109, and can access a website or the like via a web browser or an application. The user's telephone communication information analyzing apparatus 1 is also connected to the Internet network 109.
The advertisement effect analysis will be described using the flowchart of FIG.
The user has his / her own website 111 and displays an advertisement link 112 for accessing the website on the advertisement posting site 113. This advertisement posting site 113 is operated by a third party.
First, the customer accesses the advertisement insertion site 113 using his / her external telephone terminal 100. Then, the user's advertisement link 112 is selected and clicked from among a large number of advertisement links displayed on the advertisement insertion site 113 (first step step S901).
When a specific advertisement link 112 is clicked, the advertisement insertion site automatically sends the advertisement-specific number assigned to the clicked advertisement link 112 and the telephone number data of the customer to the server 114 via the Internet 109. Transmit (second step, step S902).
Here, “telephone number data” means any data based on the telephone number of the customer linked one-to-one with the customer, such as the telephone number itself, data obtained by encrypting the telephone number, or data obtained by hashing the telephone number. .
The server 114 receives and stores the advertising job number and telephone number data transmitted in the second step (third step, step S903).

Next, the customer accesses the user's website 111 by clicking the advertisement link 112 in the first step. Since the user's telephone number is displayed on the website 111, the customer makes a call to the user's telephone number using his / her external line telephone terminal 100 (fourth step, step S904). The external telephone terminal 100 used by the customer in the first step and the fourth step must be the same.
The user's telephone communication information analyzing apparatus 1 receives the customer's telephone, and the control unit transmits the user's telephone number data and the customer's telephone number data to the server 114 (fifth step, step S905).
The server 114 receives and stores the user telephone number data and the customer telephone number data transmitted in the fifth step (sixth step step S906).
Then, the server 114 determines whether or not the customer phone number data stored in the third step matches the customer phone number data stored in the sixth step (seventh step step S907).
The processing after the seventh step is not particularly limited. For example, when it is determined as “match” in the seventh step, the server 114 notifies the user to that effect, and the user is notified to the advertisement posting site. You can see the effect of placing an ad.

The present invention relates to a telephone communication information analyzing method capable of analyzing telephone communication between a user and a customer without significantly improving the existing telephone equipment configuration, and has industrial applicability. .
