IP Phone Systems Are Changing How We Communicate Today

Business phone systems hardly changed after they were introduced in the 1950s: an on-location PBX managed multiple phone lines and routed calls. Sure, there were technical advances and add-on services enhanced performance, but communication was basically limited to voice.


Today, however, there are countless ways to email, text, buddy, share, video chat, conference—and place a call. This brings tremendous advantage by increasing the speed of business.  But it also spawns equally tremendous complexity. How can IT departments keep up with administering and securing a multitude of applications? Fortunately, there’s a better way with IP phone systems.

What Are IP Phone Systems?

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 phone systems perform four main call processing duties:

  • Establishing connections between the telephone sets of two users
  • Maintaining the connections as long as needed
  • Disconnecting the connections when the users hang up
  • Providing information for accounting purposes


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 soft-phones or purpose-built hardware devices that appear much like an ordinary telephone or a cordless phone.
