What Is An IP Phone System?
At the heart of every business phone system is the PBX (Private Branch Exchange), which makes connections among the internal telephones of a business or other private organization and connect them to the public switched telephone network (PSTN). Traditional hard-wired PBX systems evolved in the 1990s to use Internet Protocol (IP) to carry calls. An IP PBX uses Voice Over Internet Protocol (VoIP) and can also be known as a VoIP PBX, IP-PBX, virtual PBX or IPBX.
IP PBX phone systems perform four main call processing duties:
An IP PBX system consists VoIP enabled phones and an IP PBX. The phones register with the IP PBX server, and when they make a call the IP PBX establishes the connection. VoIP phones can be simple software-based softphones or purpose-built hardware devices that appear much like an ordinary telephone or a cordless phone.
