Currently, many companies such as telecommunication companies, SNS companies, and the like provide an Internet phone service due to the development of the Internet and the increase in speed of the Internet. In addition, an Internet phone service using smartphone applications is provided due to the propagation of smartphones. However, as the existing Internet phone service is provided by each service company using its own server, the burden of investing in facilities to the service company, such as the extension of servers due to subscriber growth or the like, is greatly increased, and problems of the deterioration in call quality, such as a delay, disconnection, and the like due to the increase in traffic, are occurring. The present invention relates to a distributed Internet phone system for enabling subscribers to communicate with each other by establishing a server by each group unit such as a household, a company, an organization, a region and the like, instead of a server of a specific company, and to communicate with subscribers of other companies through interconnection between the servers. The present invention is capable of easily extending services by establishing the servers by group unit to provide services to group subscribers of which call volume is high. In addition, the present invention facilitates the investment in the facilities as the burden of the investment in the facilities are distributed by interconnecting a plurality of servers, established by each group unit, and providing the service to the subscribers in different groups even if the number of users is increased, thereby providing good call quality. |
