Dynamic registration method of IP extension telephone roaming

Abstract

The invention relates to a dynamic register method of IP sub-telephone roaming, wherein it arranges sub-telephone attach server address on the terminal device of sub-telephone; the terminal device registers into said server; the server provides available server address list to the terminal device; when the sub-telephone roams, the terminal device will automatically process IP connection test and voice quality test with all available server at background, and the test result will be evaluated via the response delay and loss rate of network connection, while the top one has best network condition; then the terminal device selects the best server to dynamically register; the server processes register refresh of soft exchange and service route. The invention can automatically register without changing the number of sub-telephone, to improve service quality, used in IP-FBX server and video communication system.

Description

technical field [0001] The invention relates to an IP-based voice and video communication method, in particular to a dynamic registration method for IP telephone extension roaming. Background technique [0002] As VoIP (Voice over Internet Protocol) technology becomes more mature and widely used, IP-PBX (IP-based private exchange) has also developed rapidly. More and more enterprises use IP-PBX to build their internal voice and video communication systems. For large enterprises and institutions with many branches, the method of deploying multiple IP-PBX servers in the headquarters and each branch is often used to improve the communication efficiency and communication reliability within the enterprise. [0003] IP extension roaming, as a newly emerging function of IP-PBX, can greatly provide convenience for enterprise employees on business trips and save enterprise communication expenses. Extension roaming is relatively simple to implement under a single IP-PBX server, but ...

AI Technical Summary

Problems solved by technology

It is relatively simple to implement extension roaming under a single IP-PBX server, but in a multi-server environment, it faces the problem of how to choose an access server

In the current situation, the IP extension can only be manually configured and set to register with a specific IP-PBX server, and cannot be dynamically and automatically selected according to the actual situation of the network.
