What is IP PBX?
An IP PBX is a private branch exchange that switches calls between VoIP users or traditional telephone users or between a VoIP user and a traditional telephone user on local lines while allowing all users to share a certain number of external phone lines. It works in the same way as that of a conventional PBX. It is abbreviated as IP PBX, IP-PBX, IPPBX, or IP/PBX.
How it functions?
An IP PBX phone system consists of Softphones or IP phones, IP PBX server, and an optional VoIP Gateway. IP PBX server is similar to proxy server. Whenever softphones or hardware based phones that are registered with IP PBX server wish to make calls they make a request to IP PBX to establish the connection. The IP PBX which has the directory of all phones/users and their corresponding SIP address will process the request and connects the call via either a VoIP gateway or a VoIP Service Provider to the desired destination.
