VoIP Introduction

VoIP is a communication protocol that delivers voice communications over Internet.  VoIP can be usable by three ways.

  1. Dedicated IP phones such as Cisco, Avaya IP phones
  2. An analog telephone adapter
  3. Softphone – it’s basically an application just like a telephone where a number can be dialed

The biggest advantage of VoIP is the reduction of monthly telephone bill. A service provider is needed to activate VoIp and these service providers compete with each other on the basis of minutes.
