An IP PBX is a private branch exchange that acts as the central switching system for phone calls in the business that switches calls between VoIP users on local lines while allowing all users to share a certain number of external phone lines. Old PBX is made up of two key elements: lines and stations.
The lines, sometimes also called trunks, are connections to the global public switched telephony network through the telephone companies. Stations are simply devices like telephones or other endpoint devices, fax machines, modems. PBX systems handle internal traffic between stations and behave as the gatekeeper to the outsider. PRI provides telecommunication services to offices. It is based on T-carrier(T1) line in US and Canada; it consists of 24 channels, and E-carrier(E1) line in Europe consists of 32 tracks.
An IP PBX is a system that connects telephone extensions to the public switched telephone network and provides internal communication for a business. An IP PBX is a PBX system with IP connectivity and may provide additional audio, video, or instant messaging communication utilizing the TCP/IP protocol stack.
