Voice over Internet Protocol (VoIP) is a new technology that allows you to place phone calls over a broadband Internet connection instead of a standard, analog phone line. This new technology is innovating the way we communicate by telephone.

So, How Does VoIP Work?

Simply stated, VoIP allows you to make telephone calls using the Internet by converting a voice signal from your telephone into a digital signal. Once your call is received, VoIP converts the signal back to voice. This all happens thanks to an adapter, or router, that sends the call over the Internet to the recipient's telephone company, who completes the call. It works the same way when you receive a call-your phone rings like it always has.

Placing Calls

When you place a VoIP call you'll still hear the same old dial tone. You'll even dial the phone number the same way. The difference lies in who you can call.

Some services only allow you to call other people who have the same VoIP service. Others allow you to call anyone who has a telephone number-including local, long distance, mobile, and international numbers.

Depending on the service, there are three ways to place a call:

  • Standard phone with a network adapter
  • Special VoIP phone
  • Microphone headset and computer

What Equipment is Required?

First, to use VoIP, you must have a broadband (high-speed Internet) connection. You can use T1, cable, or DSL. Secondly, you need a way to place the call. Enter the standard phone, VoIP phone, or your computer. That's it!

What About Local and Long Distance Calls?

VoIP is breaking down the traditional notions of local vs. long distance. You can often choose the area code for your phone number. And some providers charge the same rate, regardless of whether your call is to someone who is across the street or across the country. Most services also offer reduced international calling rates.

What are the Advantages and Disadvantages of VoIP?

The first advantage is cost. VoIP services offer a significant price break over traditional phone service. Also, VoIP provides many additional features that standard phone services do not.

As far as disadvantages go, one is critical. Some VoIP services will not work during power outages. Also, not all VoIP services can connect directly to emergency services through 911. Many VoIP service providers do not offer directory assistance or white page listings.

VoIP and the FCC

Historically, the Federal Communications Commission (FCC) has not regulated the Internet or services provided over it. On February 12, 2004, the FCC determined that Internet-based VoIP service was an unregulated information service. At the same time, the FCC began a broader initiative to examine its role in safeguarding the public interest in the emerging VoIP marketplace.
