Voice over Internet Protocol
Technology
The future of telephony is Internet
Protocol (IP). Instead of sending your
calls over the public switched
telephone network (PSTN), a handful of
wholesale phone companies are breaking
your voice into syllable-sized packets
and sending them over a lattice of
networks that resemble and include the
Internet.
The result: Big Savings.
The following article was written by
Chad White, Technology Investor, Sep
2000.
"Customers save between 10% and 50%
depending on the route that the phone
companies take when they use the IP
carriers to deliver their
international calls rather than PSTN
carriers. Why are IP calls cheaper?
First, IP can send at least six times
more calls over the same bandwidth as
a single PSTN call. IP calls are
compressed and on average need only 10
kilobits per second. Second, IP
software uses bandwidth better when
sending voices. The algorithms used to
encode voice into IP adapts to the
conversation. If you speak less often,
less bandwidth is used.
In contrast, the public switched
telephone network does not adapt. It
dedicates the entire expensive
bandwidth of a two-way circuit to a
conversation. If you are not using the
whole bandwidth - pausing, hesitating,
and listening - it goes to waste. Add
up all the spaces and there is lots of
waste - at least 65%. You are paying
for silence every time you call Aunt
Bertha in Timbuktu.
The savings with voice over IP (VoIP)
has phone companies handing off their
international long distance calls to
dedicated IP carriers. Last year, IP
carrier revenue grew 500% to $500
million, says the IDC. It will
increase 120% per year to $1.19
Billion in 2003:

Imagine voice as Internet data.
Today, your PC can browse five
websites, receive email and listen to
high-fidelity music - all
simultaneously while online. But
voice? You have to hang up and dial
again. Dumb.
Tomorrow, you'll stay on. Answer
multiple calls, conference them
together, have them find you wherever
you are…. All the while you are still
browsing five websites, emailing....
It will be cramped on a dialup line,
but on a DSL or a cable modem? A snap!
At some point, when we're all on one
gigantic broadband network, the
world's entire Internet traffic, phone
traffic and video traffic will pass by
our doors, ready to be plucked off for
our pleasure, our business or our
edification.
"Life will pass us by. But it will be
Everyone's lives. It will be there for
instant participation. Such is the
ultimate power of IP. "
It is obviously a large issue. Good
voice quality, few (if any) dropouts
and high availability (dial tone is
always there) must accompany and IP
based telephony solution. The Internet
connection you are using to read is an
example of a network not designed to
provide adequate quality of service
for voice. Private IP networks have
much better chance (currently) of
delivering adequate quality of
service.
