A seamless communication method for IP telephone and telephone network

Abstract

The invention relates to a seamless communication method between an IP telephone and a telephone network in the technical field of computer network communication. The main steps are: talk to the remote user, send a call request to the remote gateway; the gateway analyzes the target terminal type, if the two parties in the call are IP terminals, it is mainly responsible for negotiating the call parameters, and then the two parties complete the subsequent call process , if the target terminal is a fixed phone, the gateway will convert the corresponding analog and digital signals, and assist in the completion of the subsequent call process; the gateway receives the hang up signal from the IP terminal or the telephone network, releases the call resources, and ends the call . Main advantages: make full use of network resources, and can transmit more calls on the same line than when using analog technology, greatly improving efficiency. It is convenient and easy to use, and the calling conditions are not limited.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a seamless communication method between an IP telephone and a telephone network. Background technique [0002] At present, with the development of computer technology, computer networks are becoming more and more popular, and the use of IP phones is becoming more and more extensive. Users can access the network through various devices such as PCs, laptops, PDAs, and mobile phones in most places. While enjoying the rich and colorful online world, users can also easily chat with distant friends through IP phones. But at present, IP phones can only communicate between PCs. If you want to call a fixed phone through a PC, you must configure a MODEM and a telephone line, which continuously increases the cost of the equipment and is very inconvenient. [0003] In order to solve these problems, it is necessary to provide users with an intermediate proxy layer-IP2P...
