What is VoIP?


Voice over Internet Protocol (VoIP) is a technology that utilizes a company's local area network (LAN) to place and receive telephone calls over the internet versus traditional phone lines.

A VoIP telephone system connects Session Initiation Protocol (SIP) phones, an IP Private Branch Exchange (PBX) server and a VOIP Gateway to connect to existing Public Switched Telephone Network (PSTN) lines.

An IP PBX server acts as a centralized hub to which other IP-enabled devices connect and communicate; SIP phones (software or hardware-based) exchange call routing information and connect to internal or external exchanges via a VoIP gateway or VoIP service provider.

IP PBX systems deliver considerable savings in management, maintenance, and ongoing call costs in your business's telecommunication budgeting.

Business VoIP has 3 major components:

  • A VoIP server - also known as an IP PBX server, this hardware replaces traditional PBX or phone systems.
  • Customer Premise Equipment (CPE) - includes hardware such as handsets, routers and switches; all of which work in concert to establish dial tone when you pick up your phone.
  • Networks: - three networks must work together 
    a) VoIP server network - made up of hardware and a high bandwidth and availability environment
    b) Client Premise Equipment (CPE) network - your company's hardware and internal LAN
    c) Internet connectivity between the VoIP server and CPE - your business's connection to the internet
