Internet
Voice, also known as Voice
over Internet Protocol (VoIP),
is a technology that allows
you to make telephone calls
using a broadband Internet
connection instead of a
regular (or analog) phone
line. Some services using
VoIP may only allow you
to call other people using
the same service, but others
may allow you to call anyone
who has a telephone number
- including local, long
distance, mobile, and international
numbers. Also, while some
services only work over
your computer or a special
VoIP phone, other services
allow you to use a traditional
phone through an adaptor.
What
is VoIP/Internet Voice?
VoIP
allows you to make telephone
calls using a computer network,
over a data network like
the Internet. VoIP converts
the voice signal from your
telephone into a digital
signal that travels over
the internet then converts
it back at the other end
so you can speak to anyone
with a regular phone number.
When placing a VoIP call
using a phone with an adapter,
you'll hear a dial tone
and dial just as you always
have. VoIP may also allow
you to make a call directly
from a computer using a
conventional telephone or
a microphone.
How Can I Place a VoIP Call?
Depending on the service, one way to place a VoIP call
is to pick up your phone
and dial the number, using
an adaptor that connects
to your existing high-speed
Internet connection. The
call goes through your local
telephone company to a VoIP
provider. The phone call
goes over the Internet to
the called party's local
telephone company for the
completion of the call.
Another way is to utilize
a microphone headset plugged
into your computer. The
number is placed using the
keyboard and is routed through
your cable modem.
What
Kind of Equipment Do I Need?
A
broadband (high speed Internet)
connection is required.
This can be through a cable
modem, or high speed services
such as DSL or a local area
network. You can hook up
an inexpensive microphone
to your computer and send
your voice through a cable
modem or connect a phone
directly to a telephone
adaptor.
Is
there a difference between
making a Local Call and
a Long Distance Call?
Some VoIP
providers offer their services
for free, normally only
for calls to other subscribers
to the service. Your VoIP
provider may permit you
to select an area code different
from the area in which you
live. This means you may
not incur long distance
charges if you call a number
in your area code regardless
of geography. It also means
that people who call you
may incur long distance
charges depending on their
area code and service.
Some VoIP
providers charge for a long
distance call to a number
outside your calling area,
similar to existing, traditional
wireline telephone service.
Other VoIP providers permit
you to call anywhere at
a flat rate for a fixed
number of minutes.
If
I have Internet Voice service,
who can I call?
Depending upon your service,
you might be limited only
to other subscribers to
the service, or you may be able to call any phone number, anywhere
in the world. The call can
be made to a local number,
a mobile phone, to a long
distance number, or an international
number. You may even utilize
the service to speak with
more than one person at
a time. The person you are
calling does not need any
special equipment, just
a phone.
What
Are Some Advantages of Internet
Voice?
Because Internet
Voice is digital,
it may offer features and
services that are not available
with a traditional phone.
If you have a broadband
internet connection, you
need not maintain and pay
the additional cost for
a line just to make telephone
calls.
With many
Internet
Voice plans you can
talk for as long as you
want with any person in
the world (the requirement
is that the other person
has an Internet connection).
You can also talk with many
people at the same time
without any additional cost.
What
Are Some disadvantages of
Internet Voice?
If
you're considering replacing
your traditional telephone
service with Internet Voice,
there are some possible
differences:
-
Some
Internet Voice services
don't work during power
outages and the service
provider may not offer
backup power;
-
It
may be difficult for
some Internet Voice
services to seamlessly
connect with the 911
dispatch center or identify
the location of Internet
Voice 911 callers;
-
They
may or may not offer
white page listings.
Can
I use my Computer While
I talk on the Phone?
Yes
Can
I Take My Phone Adapter
with me When I Travel?
You may be able to use your
VoIP service wherever you
travel as long as you have
a high speed Internet connection
available. In that case
it would work the same as
from your home or business.
Does
my Computer Have to be Turned
on?
Not if you are making calls
with a phone and adaptor
or special VoIP phone, but
your broadband Internet
connection needs to be active.
You can also use your computer
while talking on the phone.
How Do I Know If I have a VoIP phone Call?
It
will ring like any other
call.
Can I
make free or cheaper phone
calls using the Internet?
Yes. Phone, fax and video
calls (IP telephony) can
now be placed over the Internet
(or any IP network) using
market available client
software or hardware. In
most instances, users will
only need to make a one-time
purchase of client software
or hardware to begin placing
unlimited long distance
calls for the cost of an
Internet connection. The
quality of the calls will
not match that of calls
placed over the traditional
phone network but it should
be as good as ham radio
or cb communications. With
additional hardware and
software purchases, higher
quality communications can
be achieved.
How
does the technology work?
Briefly, an Internet telephony
application compresses and
digitizes your analog voice
signals and sends them as
individual packets across
an IP network (a digital
network) to the recipient
Internet telephony application.
The recipient application
then decompresses the voice
transmissions and you have
Internet voice communications.
Internet
calls can be supported from
PC
to PC, PC
to Phone, Phone to PC
or Phone to Phone:
PC
to PC
Allows Internet users to
exclusively utilize PCs
to place or receive a phone
call through the use of
a software or hardware application.
This method of communication
requires that the user's
computer have a microphone,
speakers and sound card.
However, besides just making
phone calls, many of the
PC to PC software phone
applications also enable
users to hold group conferences
(3 or more people), share
the same PC screen, or surf
the Internet as a group.
In addition, some PC to
PC solutions also support
video transmissions through
the use of a PC camera.
PC
to Phone or Phone to PC
Allows Internet users to
place a call from their
PC to a traditional phone
or to receive a call on
their PC from a traditional
phone. These forms of communication
utilize software or hardware
applications that can connect
a phone to a computer or
that connect between the
phone and the wall jack.
Phone to Phone
Allows Internet users to
place an Internet call directly
from a traditional phone
to a traditional phone.
With some solutions, a computer
is not even necessary. This
type of communication generally
requires the user to open
an account with an Internet
phone company and pay per
minute charges, however,
there are some client products
that will enable you to
use traditional phones without
paying for the service.
What do I need to begin utilizing the Internet to make free or
cheaper phone calls?
Generally, you will need
at least a 75 MHz system,
with a sound card, microphone,
speakers, a connection to
the Internet and the software
or hardware application
that will enable you to
place and receive calls
over the Internet. Most
of the Internet telephony
applications will only allow
you to communicate with
other users of the same
application, so both you
and your call's recipient
must be using the same Internet
telephone application.
How to
begin utilizing the Internet
to make phone calls:
Individuals or small businesses
that want to make Internet
calls will need to download
an Internet phone software
program or obtain an Internet
phone device. It will need
to be installed in or connected
to the device (computer
or telephone) that you would
like to use to make a call,
configured to operate properly,
then you can begin making
calls.
Medium to large sized businesses
that would like to utilize
the Internet to place and
receive calls can utilize
the software or hardware
applications mentioned above,
however, those applications
do not always provide the
best possible communications
quality and typically only
allow one user per application
to place or receive calls.
There are many other Internet
communications solutions
that are better suited for
corporations as they enable
corporations to implement
Internet communication solutions
over a PBX, to voice enable
web sites, to use an existing
or virtual private IP network
to communicate between multiple
corporate locations, or
even to offer Internet telephone
services. These solutions
will cost more but the ROI
can be expected within a
year of implementation.
Individuals and corporations
can also utilize one of
the many Internet phone
companies (ITSPs) to place
calls from a PC or phone
to any PC or phone in the
world. Using an Internet
phone company will enable
you to bypass the initial
purchase of software or
hardware equipment, however,
you will have to pay per
minute charges associated
with phone bills .
How
to enhance your Internet
phone experience:
To enhance your telecom
experience, you can also
purchase additional equipment
such as headphones with
an attached microphone (recommended),
a camera (for video communications),
or audio and video cards
specifically designed for
Internet communications.
