Introduction

VOIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet.
If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company.

 

How does VOIP work?

A way is required to turn analog phone signals into digital signals that can be sent over the Internet.
This function can either be included into the phone itself or in a separate box like an ATA .

Applications using VOIP

Traditional telephony applications, such as outbound call center applications and inbound IVR applications, normally can be run on VOIP.

Why use VOIP?

There are two major reasons to use VOIP

  • Lower Cost
  • Increased functionality

Lower Cost

In general phone service via VOIP costs less than equivalent service from traditional sources. This is largely a function of traditional phone services either being monopolies or government entities. There are also some cost savings due to using a single network to carry voice and data. This is especially true when users have existing under-utilized network capacity that they can use for VOIP without any additional costs.

In the most extreme case, users see VOIP phone calls (even international) as FREE. While there is a cost for their Internet service, using VOIP over this service may not involve any extra charges, so the users view the calls as free. There are a number of services that have sprung up to facilitate this type of "free" VOIP call.

Increased Functionality

VOIP makes easy some things that are difficult to impossible with traditional phone networks.

  • Incoming phone calls are automatically routed to your VOIP phone where ever you plug it into the network. Take your VOIP phone with you on a trip, and anywhere you connect it to the Internet, you can receive your incoming calls.
  • Call center agents using VOIP phones can easily work from anywhere with a good Internet connection.
