When the transmission data of the display terminal is received, log data thereof is separately recorded and the display terminal is authenticated. The sender CID is extracted to check the sender's CID. In other words, the caller checks whether the caller has previously set the caller information. If the sender information cannot be provided, it is received in the DB server side transmission data through the internet network, the CID is stored, and the information is transmitted to the display terminal. If there is data on the sender information, search the DB to extract address data (information on the consent or rejection of the address indication of the CID), transmit the data to the caller indication terminal, and record log data for this separately. When CB server side transmission and data is received through internet network, check whether caller has agreed to display address. If the caller has already agreed to the address indication, the information on the address indicator of the caller is transmitted to the caller indicating terminal. If the caller has not yet agreed on the address indication, the DTMF signal is received through the voice guidance to confirm the agreement. If the caller agrees to display his or her information, extract the consent data (caller CID, time, consent result, etc.) and send it to the DB, record the update log data in the DB, store the CID and address data, and send it to the caller indication terminal. do. If the sender refuses to provide information such as address, the rejected data (caller CID, time, rejection result, etc.) is extracted and transmitted to the DB, the DB update log data is recorded, and the information is sent to the sender display terminal. When the information on the caller's address is input to the caller's display terminal, the caller's information is displayed on the display unit (LCD output), and the caller's display terminal is beeped so that the receiver can answer the call. The called party can check the telephone tone and caller ID indication, and the call is made possible. If the caller does not agree to display his or her address, an indication is displayed on the display. If the caller agrees, information such as the caller's address is displayed. The recipient can then print the button by inputting the information such as the sender's address shown on the display unit. If the person who agrees to display the caller's address on the display terminal calls and receives the order online through the answering machine, the receiver does not talk directly but later confirms the order through the LCD display or through the printer output.
