IP PBX Systems

PBX (private branch exchange) is a telephone system within an enterprise that switches calls between enterprise users on local lines while allowing all users to share a certain number of external phone lines.The main purpose of a PBX is to save the cost of requiring a line for each user to the telephone company's central office. The PBX is owned and operated by the enterprise rather than the telephone company (which may be a supplier or service provider, however). Private branch exchanges used analog technology originally. Today, PBXs use digital technology (digital signals are converted to analog for outside calls on the local loop using plain old telephone service (POTS ). PBX is available in multiple models to fit your business need with easy installation, flexible connectivity, and convenient management.

PBX includes:

• Telephone trunk (multiple phone) lines that terminate at the PBX.


• A computer with memory that manages the switching of the calls within the PBX and in and out of it.


• The network of lines within the PBX.


• A console or switchboard for a human operator (optional).

IP PBX known as a Unified Communications System or business phone system, a PBX acts as the central switching system for phone calls within a business. PBX systems handle internal traffic between stations and act as the gatekeeper to the outside world. The initials PBX stand for Private Branch Exchange, a very old fashioned term for a system that has evolved significantly over the past century.
