PBX stands for Private Branch Exchanges. PBX systems are "mini telephone companies" used mainly by businesses and hotels. PBXs allow for special features like voice mail and hold and transfers. PBX by itself, though, is becoming an obsolete technology. PBX VoIP is the future of business phone systems. An IP PBX helps businesses consolidate their current network infrastructure to support both PBX functionality and data network. It also means that employees moving around in the office can just plug their phone into a network jack or log on from their PCs. Companies adding a VoIP PBX will need to look at possibly upgrading their routers, servers, and protocols. PBX Voice over Internet Protocol will mean more strain on bandwidth, but the new VoIP PBX can use unused portions of T1 or T3 lines to take up the slack. Some VoIP systems allow the employees to get on the system anywhere on the network and just route incoming calls and data to their station. Altigen Communications (Altigen.com) has PBX system with VoIP technology. These phone systems have the ability to expand by networking multiple locations and remote systems together. The PBX VoIP systems are as follows:
