So what is VoIP, IP
Telephony?

VoIP stands for "voice
over internet protocols". It is a technology used to
transport a normal telephone call (voice) using an
established Local Area or Wide Area Network. A good
example of a practical application using VoIP is
where a company has more than one site and regularly
communicates between them, sending and receiving
data traffic over existing inter-company data
circuits. By having a VoIP, IP telephony solution,
you could also use these existing data circuits to
send and receive voice traffic between sites for no
additional cost as if all the sites shared the same
telephone system.
Why
is everyone talking about VoIP, IP Telephony?
As companies strive
for greater efficiency and to promote the optimum in
cost effective working structures, the chance to
increase functionality and at the same time save
money is an extremely appealing possibility.
Communication systems are the life blood for most
thriving businesses, and it can be a term used to
describe a wide variety of methods that we use
today. Two obvious candidates for this category are
telephony and our computer networks, and although we
see them as crucial to our day to day activities, we
have up till now seen them as separate entities.
Great benefits can be gained if ways can be found to
unify these two methods of communication from an
operational point of view.
Is
VoIP the way forward?
VoIP is a
here-and-now technology and will most certainly
be the way forward in the long term. The benefits of
using VoIP will be different for most companies
depending upon their every day needs and business
processes, but there are many generic benefits.
Infrastructure that is comprised of a single network
should lower installation and maintenance costs,
minimize charges from network providers and in
theory should make any office moves and changes
easier to manage. As working practices change for us
all, more and more people are breaking away from the
idea of traveling into the office and are taking up
the idea of working from home or on the move. Home
or mobile workers can take advantage of such things
as unified messaging where voice messages
delivered into their mailbox at the office, can be
sent to them as an e-mail and replayed via their
email client application.
Quality
of Service
Quality of Service
can be an important factor when considering a move
to a VoIP solution. Unlike data, which is sent
chopped up in packet form from one point to another,
voice is a real time application and any packets
sent containing it must arrive in the correct order
and in a timely fashion if they are to be of any use
at all. Any existing hardware and topography may
well need to be upgraded and pre-planned to achieve
an acceptable level.
