Business and the system that supports it

The business is roughly divided into two types: inbound, which receives calls from consumers, and outbound, which makes calls from companies such as sales. Some centers handle both, while others only handle either.

1990 eraTechnology and experience are required to build the entire system, such as mechanization to lighten the burden on the operator, and since it has become more sophisticated in terms of operations such as recruitment training for operators and extension of inbound reception time,ア ウ ト ソ ー シ ン グBecame the mainstream.

Inbound work flow

Inbound work is basically performed by the following procedure.

  1. Automatic voice responseAt the first reception, the pushbutton signal (DTMF), etc. to select the message.
  2. Auto answerIf you are satisfied withAutomatic voice response deviceCorrespondence is completed only.
  3. If operator correspondence is required, the operator will be assigned to the selected operator specialized in the matter. Even in that case, the typical response parts such as company name and operator name are mostly recorded in advance.
  4. If the operator is unable to respond (the reception desk while seated is occupied), the user is notified by an automatic response that there is congestion.
  5. When the operator starts handling, the identity of the inquirer (customer identification) is first performed. It is said that the confirmation is often made mainly by the customer's first and last name, registered address, registered telephone number, customer number, etc.
  6. After the talk between the operator and the inquirer is over, the operator writes and saves the communication of the talk with the inquirer in the terminal. Most of these processes are repeated.

Outbound business flow

Outbound work is basically performed by the following procedure.

  1. Automatic predictive dialing (predictive dialing) by predicting the operator's call termination and customer situation to the telephone number recorded in the database.
  2. Only the calls answered by the customer are distributed to the operator.
  3. The operator responds while referring to the customer information database.

In many business establishments, it is performed when there is a high probability that the customer will stay at home and there is no inconvenience, and there is little inbound work, and the operator is vacant.

Call center business system

Although there are some differences, most call centers have the following configuration.

In the server room

The following devices are placed in a room isolated from the operator from the viewpoint of personal information protection management, and that room is called a server room or machine room. It is a shared facility in the call center. A plurality of these devices will be installed depending on the size of the call center.

Customer information, product information, order information, response history, etc. are recorded. It is generally installed outside the call center, but in some cases a part is cut out and copied to the system inside the call center.
ACD (Private branch exchange)
The incoming call is distributed to each operator. It has a routing function such as changing the number of telephones to be distributed according to the operator's ability and work style, and in cooperation with a database server, distributing telephones from customers requiring attention to experienced operators. Dialer to automatically call customers for outbound operations[1]Is used.
The function of recording various statistical information and providing it as an analysis report is also essential.
All call recording
A device that records all call content. It can be used as evidence when a trouble occurs,Education, Used for recording/verifying call contents.
ACDA server for linking with other systems. For exampleACDA typical example is to link the caller/incoming telephone number with the business system together with the event from and display the customer and its related information and the response history in the business system based on this. It is also common for the business system to send the telephone number in cooperation.

Operator desktop equipment

The following equipment is installed at each operator seat. From the viewpoint of work efficiency and prevention of personal information leakage, call centers shared by adjacent operators are rare.

Private branch exchange desktop terminal
Receive a call, hang up, put on hold. A box-shaped device with buttons for basic phone operations such as operator login, logout, and leaving the phone, to which a headset is connected. In addition, there is an SV call button for calling the person in charge (SV; Supervisor). Depending on the equipment, these buttons are displayed on the screen and operated with a mouse or keyboard.
Use a headset to operate the computer with both hands while talking to the customer. Call center headsets are equipped with a special microphone () that collects only the voice from your mouth, making it difficult to pick up conversations between operators next door. This is to secure a clear conversation with the other party while the operator is seated in a large number of rows, but it is also useful from the viewpoint of preventing personal information leakage.

Network isolation

In order to completely separate the network that stores personal information from the business processing network, each terminal device (oftenPersonal computerDivert) is placed. Normally, it is not possible to print from terminals belonging to the personal information network, and it is necessary to prevent leakage of personal information. At the same time, update and editing of display contents are also prohibited at some call centers, and personal information is prevented from being altered intentionally or by mistake. As the two types of networks are physically separated and used as shown on the left, one operator seat has twoconsole(With display deviceInput deviceSet) is placed.

Main display
A display for displaying the information entered by the operator, such as customer inquiries and orders. It also displays the call time with the customer who is on call and the total call time for the day. In some cases, an operation panel with the function of a desktop terminal is displayed.
Sub display

Depending on the call center, you can divert the light shield hood or use a privacy filter that allows the display to pass through only from the front (Polarized lightA filter is attached to prevent operators from seeing through the seats next to them to prevent leakage of personal information, and at the same time reduce the suspicion of leakage of personal information to the operator.
Keyboard, mouse
A general keyboard is connected to enter order details. Although it is often possible to perform all operations with only the keyboard, in recent years, in order to reduce the educational cost of operating the device, a mouse is connected so that it can be operated more visually or a display is used instead of the mouse.Touch panelIn some cases, it is a formula.

Location conditions

For this reason, when talking to the operator of the call center, there is a shift in the geographical sense. (When the person who inquired said that he would call to Tokyo, the call center on the receiving side was in Okinawa, so the operator was in Tokyo I do not know the geography, and as a result, it takes time to explain the location). Exceptionally, NTT104 can retrieve data nationwide by computer, so if you know the address, you can handle telephone numbers without problems, and centers are located all over the country.

If you open a call center in a rural area, it is far from big cities such as Tokyo and Osaka,Leased line-IP phone(IP Centrex) Etc. together to reduce the communication cost of companies that open call centers (when viewed in Okinawa, it is adjacent due to the exception of remote islands)MAIs considered a districtKagoshimaExcept for, all farthest distance calls will be very expensive.

Call centers are set up all over the country, but especiallySapporo,Sendai cityIs one of the areas where call centers are often advanced due to the fact that the language is close to the standard language and the local governments are enthusiastic about attracting them. In recent years, the population of women and students is large, and from the perspective of risk aversion after the Great East Japan Earthquake,Fukuoka CityThe number of center establishments in is increasing.


Moreover,international callIs cheapIP phoneIn order to use the time difference for 24 hours, there are call centers in multiple countries where labor costs are low, and there are businesses that outsource the work, and the number of companies outsourcing is increasing.

Personal information protection measures

Since the call center handles a large amount of personal information of customers, it is usual that strict personal information protection measures are taken. However, the following measures are not necessarily implemented at all call centers.

Access control
ID cardBiometricsEntrance and exit management is performed using, and the appearance of entering and leaving the room is taken by a security camera.
Peep measures
In many cases, a privacy filter is applied to the display of the operator's desk so that the characters displayed on the screen cannot be discriminated from an oblique direction.
Professional headsets used in call center operations are designed to pick up only a few tens of centimeters of sound around the microphone. Even if the user speaks out loud in a distant place in the center, it is difficult for the caller customer to hear the content.
Countermeasures for illegal acquisition of information
The personal information displayed on the screen is only the personal information of the person who is currently calling so that the operator cannot obtain personal information that is unnecessary for the work, and the personal information of other customers can be arbitrarily searched. Rarely. Even if you can search, it is almost always that the search is recorded.
Away management
If an IC card reader for inserting an ID card is installed in each operator console, the operator console cannot be used unless the ID card is inserted, and the operator console is locked when the ID card is pulled out. There are also cases. By providing a rest space and entrance to the toilet outside the operator room and forcing ID card authentication when leaving the operator room, the ID card can be reliably pulled out when leaving the operator. I try not to keep my personal information displayed on the desk.

DHCPServer not used
From the viewpoint of preventing personal information leakage and computer virus inflow, it is extremely rare to use a DHCP server in building a network in the center.
