VOIP PHONES – HISTORY OF TELEPHONY

1
VOIP PHONES HISTORY OF TELEPHONY Since the
beginning of time, communication has been the key
element in the success of any mission, home,
business and other human interactions. No
doubt, therefore, a number of technological
advancements in this space have been made. VoIP
phones meaning phones that use voice over
internet protocol technology is one of those
advancements. This is without a doubt the
most celebrated telephony advancements today.
VoIP Phones POTS Much earlier, in the twentieth
century to be precise businesses, campuses and
homes used what was known as POTS (Plain Old
Telephone system). This is basically the
traditional standard telephone technology that
used the public switched telephone network
(PSTN). This technology incorporated copper
and fiber optic wires to make a network.
These wires crisscrossed the globe and the
cost incurred depended on the length of the
wire used. It was therefore very
expensive to make long distance calls. For a
business to have a phone system, it meant renting
the length of wire owned by the telephony
organization. Traditional telephony used
circuit switching meaning that for the
entire duration of the transmission a dedicated
circuit was left open. Packets This is an
improvement on the traditional telephony. You can
say that it is basically traditional telephony
services only this time operating via computer
network through the use of packet switched
protocol. Packets simply act as electronic
envelopes into which voice signals to be
transmitted are put. Packets include not only the
voice signal but also the network addresses of
both the sender and the receiver. One major
advantage of this over the standard telephony
services is that it has a higher bandwidth
meaning that it can transmit more information per
unit of time than the former. IP Telephony

IP technology was way more superior to the two
earlier telephony services. It uses the internet
protocol for its transmission and this comes with
quite a number of additional capabilities.
Initially, this telephony service depended on
the internet but today this is not
absolutely necessary. VoIP phones are
interoperable meaning that they work perfectly
over all kinds of networks. Another advantage is
that they are very portable and can work with
different gargets, not just phones. The sound
quality is also ery Ðlear. WheY this
teÐhYology ?as first iYtroduÐed iYto the
warket, it ÐouldYt Ðowpete with the
traditional standard telephony in terms of sound
clarity. Over time though, this has been improved
and now the sound is transmitted very
clearly. Voice over Internet Protocol phones
is relatively more affordable. This is because
this technology eliminated the need for use of
copper and fiber optic wires. This, therefore,
means that even smaller organizations can now
afford a good telephone system unlike in the past
where a company had to incur the cost of renting
the wire depending on the length. There are
quite a number of VoIP phones available in the
market and these include wireless telephones,
softphones, and conference phones. The
wajor adaYtage of ?ireless phoYes is that
they doYt incorporate wires that limit movement
while making a call. A softphone is simply
software installed to a computer giving it phone
capabilities. Conference phones, on the other
hand, are best where calls need to de traYswitted
to wultiple partiÐipaYts. DepeYdiYg oY the
orgaYizatioYs Yeed, all these telephoYes can be
quite vital for communication. Article Source
