Embodiment Construction

[0019] The dynamic registration method of the roaming IP telephone extension of the present invention, the equipment involved in concrete implementation comprises the terminal equipment of IP telephone extension and IP-PBX server, wherein, IP-PBX server (referred to as server) is divided into extension home server, remote server and Extension server.

[0020] The extension home server is the local server for the initial registration of the terminal equipment of the IP phone extension.

[0021] The remote server refers to all other servers except the local server in the communication network.

[0022] The extension server server is the remote server with the best communication quality registered in the communication network when the IP phone extension is roaming.

[0023] The dynamic registration method of the roaming IP telephone extension of the present invention includes two aspects, one is the control program of the terminal equipment dynamic registration of the IP telepho...

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 roaming IP telephone extensions. Background technique [0002] Along with VoIP (Voice Transmission Based on Internet Protocol) technology matures day by day and is widely used, IP-PBX (Private Exchange Based on IP) has also obtained rapid development. More and more enterprises use IP-PBX to build the voice and video communication system within the enterprise. For large enterprises and institutions with many branches, they often adopt the method of deploying multiple IP-PBX servers in the headquarters and each branch to improve the communication efficiency and reliability within the enterprise. [0003] As a new function of IP-PBX, IP extension roaming can greatly provide convenience for employees on business trips and save enterprise communication expenses. It is relatively simple to implement extension roaming under a single ...
