Problems solved by technology

[0007] However, the capacity and reliability of the existing IP-PBX cannot meet the needs of large enterprises and institutions. The main reason is that the existing IP-PBX system has the following shortcomings:
[0008] First of all, when the existing IP-PBX system centralizes the softswitch service and the media gateway service on the same server for processing, the call registration, status query, and call control of the softswitch service will occupy a large amount of system resources, while the media gateway service The teleconferencing function, code conversion, etc. will also take up a lot of system resources, which is the bottleneck of IP-PBX services
[0009] In addition, the existing IP-PBX system not only undertakes the registration, authentication, and call connection establishment of locally registered IP phones, but also undertakes the call establishment, authentication, and code conversion for the built-in gateway of the IP-PBX and the incoming call from the external gateway side. function, which will also take up a lot of system resources, which is also a reason for the bottleneck of IP-PBX services

Embodiment Construction

[0024] Such as figure 1 As shown, it is the IP-PBX system cluster network architecture diagram of the present invention. The system includes two central servers, namely central server 10 and backup central server 20, and two media servers, respectively media server 30 and backup media server 40; the present invention also includes a local softswitch server 50. Of course, the configuration of the number of central server, media server and local softswitch server can be set according to the needs. Generally speaking, more than two central server and media Load and capacity conditions set one or more.

[0025] The central server 10 has a softswitch service module 11 and a database 12, and the standby server 20 also has a softswitch service module 21 and a database 22. Only one of the central server 10 and the standby server 20 is used for system work at the same time, and the standby server 20 is only activated when the central server 10 breaks down or other emergencies. Howev...

Abstract

The invention discloses an IP-PBX system which can realize a system cluster and improves the capacity of the system and the efficiency of the system through function separation of a softswitch service and a media gateway. To solve the problem, the technical proposal of the IP-PBX system of the invention is that: the IP-PBX system at least comprises more than two servers, wherein, the servers comprise a central server and a media server; the central server comprises a softswitch service module and a database; the media server comprises a media gateway module; a communication record of the media server is recorded in the database on the central server. The system can also comprise more than one local softswitch servers, each server comprises a local softswitch service module and a built-in gateway; the local softswitch service module is used to process local softswitch services and process the call control of the built-in gateway.

Description

technical field [0001] The present invention relates to an IP-PBX (IP-based private exchange, The Internet Protocol Private Branch eXchange) system. Background technique [0002] With the maturity and wide application of VoIP (Voice over Internet Protocol, voice transmission based on Internet Protocol) technology, IP-PBX has been applied in more and more enterprises. [0003] Many companies find that traditional phone systems are not only expensive to maintain, but also limited in their ability to support the dispersed work of employees. To make all communications unimpeded, IT administrators are now starting to deploy an IP-based corporate phone system -- IP-PBX. These systems can fully integrate voice communications into a company's data network, creating a unified voice and data network that connects offices and employees across the globe. [0004] The most notable feature of IP-PBX is that it becomes an integrated communication system. Through the telecommunication net...
