Description

How to Display Caller ID of Internet Phone and Service Server

The following description relates to a caller ID display service, and more particularly, to a service server and a method for displaying that the call is an international call by detecting that the Internet call is originated from abroad.

Criminals are increasingly making phone financial frauds overseas through Voice Phishing. In particular, while the sender impersonates a prosecution, a police officer, a court, and the like, the sender uses the psychology of the receiver to cause damages such as financial damage and personal information leakage.

Conventionally, the service which prohibits the change of a calling number with respect to an IP telephone terminal is provided. The service prohibiting the change of the calling number only provides verification of the phone number given by the service provider, and the public institution phone number can check the authenticity of the phone number by interworking with the database.

If you use IP-PBX (Internet Protocol Private Branch Exchange) for voice phishing in Korea, you can apply immediate legal sanctions based on IP tracking. However, when an Internet telephone apparatus (for example, an IP-PBX or a user terminal) registered in Korea is used abroad, the telephone number used in Korea can be displayed as a calling party number for voice phishing. Sanctions are not possible if the internet phone is used for voice phishing abroad by using a normally registered internet phone by using a lost or hacked internet phone.

Accordingly, in order to prevent voice phishing through internet telephony, it is necessary to control a service that detects an overseas IP access from a service server.

The purpose is to track the origin of Internet calls on the service server to reduce personal and social costs incurred by intelligently evolving voice phishing damage.
