Pros And Cons Of Getting VOIP Right Now
by: Ron King
You have a telephone, right? You have a computer, right? You want to
save money, right? BAM, you are a VOIP (Voice Over Internet Protocol)
candidate.
It is inevitable that VOIP will replace traditional telephone service at
some point. The only question is when should you jump in?
VOIP is quickly becoming more reliable and receiving wider acceptance.
In fact, phone companies are already taking advantage of the technology
to provide cheaper long distance rates. Like any emerging technology,
however, there are kinks in the system that are still being worked out.
Advantages
VOIP has many advantages over regular phone service. One primary
advantage is its low cost. If you have a fast Internet connection (DSL
or cable), you can make PC-to-PC phone calls anywhere in the world FREE.
PC-to-phone connections usually have a charge, but probably still
cheaper than regular phone service.
You can sign up with a VOIP service provider for a monthly fee and get
unlimited calls within a specified geographic area. For example, some
VOIP services in the United States allow connections anywhere in North
America for no extra charge. International calls are charged at a modest
rate.
Another advantage is its portability. You can make and receive phone
calls wherever there is a broadband connection by simply signing in to
your VOIP account. This makes VOIP as convenient as e-mail. When you are
traveling, you simply pack a headset or Internet phone; then you can
talk to family or colleagues for next to nothing.
Phone-to-phone VOIP is also portable. Internet phones are small and
light enough to take anywhere. When you sign up with a VOIP service
provider, the Internet phone or adaptor used by that service is assigned
a unique number. This 'phone number' remains valid, even if your VOIP
service is in Los Angeles and you are connected to the Internet in London.
When plugged into a broadband connection, anywhere in the world, you can
make and receive calls as though you were at home .
Features like call forwarding, call waiting, voicemail, caller ID and
3way-calling, are included with Internet telephone at no extra charge.
While you are talking on the phone, you can send pictures and documents
at the same time.
Disadvantages
There are a few glitches that still interfere with the technology's
broad acceptance by the public. Lack of continuous service during power
outages and emergency calling are the 2 biggest hurdles.
Conventional phone service continues by the current supplied through the
phone lineduring a blackout. This isn't possible with Internet phones.
When the power goes, there goes VOIP service. Battery backups and power
generators that provide electricity are the current solutions to this
problem.
A major concern involves emergency 911 calls. For the most part, VOIP
services aren't useful in emergencies. Traditional phone equipment can
trace the locations of calls. Emergency calls are diverted to the
nearest call center where the operator can identify your location, in
the event you can't talk. With VOIP, there is no way currently to
determine where Internet calls are originating. There is an emerging
standard called e911 however, which is attempting to solve this
limitation.
VOIP also has sound quality and reliability problems. Data sent across
the Internet usually arrives at its destination scrambled. E-mail and
documents can be reassembled in the correct order when it arrives. Voice
data also arrives scrambled, but it's more complicated because of the
real-time nature of VOIP. Some data packets may have to be dropped when
they don't arrive in time, in order to make voice connections with the
least delay. This can cause brief silences in the audio stream.
Distance and speed of the connection determine the amount of data lost.
Some networks receive more traffic and thus are more likely to cause
audio dropouts. One way to provide high quality audio connections is to
create dedicated data paths.
With the incredible amount of work dedicated to VOIP, these
disadvantages will no doubt be resolved withinin the next 2 years. It is
expected that by then VOIP will have widespread consumer acceptance.
