What a PBX telephone System is, and
how it Works
•
•
“Private Branch Exchange,” that is what PBX stands for, it is a customizable private
telephone network that is often used within a company or business.
Users of the PBX telephone system can share a number of outside lines to make
external calls comfortably. A PBX system interlinks the internal telephone in a
company as well as connects them to the PSTN or the public switched telephone
network, the SIP Trunks, and the VoIP providers.
 VoIP PBX
– VoIP systems convert telephone calls into data packages that can be sent over to other
computer networks. The service returns for investing on VoIP will range with the phone
service provider.
 Virtual PBX
– Having a company hosting or providing the virtual PBX service comes with some unique
advantages. That means you’ll not worry about space or physical limits when your company
grows. In fact, you can easily add more phone lines depending on demand.
 Centrex
– Companies can manage their telephone systems without going PBX with the Centrex
technology option. This is a central office exchange and allows the phone company to provide
an exact equivalent of a PBX.
