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. |
