 Voice over Internet Protocol is a term used for
voice being transported via the internet.
 The data network involved might be the Internet
itself, a corporate intranet, or managed networks
used by local or long distance carriers and ISPs.

 VoIP (Voice over Internet Protocol) is a term used
for voice being transported via the internet. The
data network involved might be the Internet
itself, a corporate intranet, or managed networks
used by local or long distance carriers and ISPs.
 The protocols used to carry the signal over the IP
network are commonly referred to as Voice over
IP. VoIP is a new technology, but it builds upon
existing digital processing

 All digital audio systems including digital phone,
perform three functions on the audio signal they
receive:
1) Digitize it which means it is converted into
computer data .
2) Compress it to reduce the amount of data needing
to be stored
3) Transmit it to the intended destination thereafter,
when a person speaks his or her own voice changes
in power and tone during the utterance.

 A computer connected to
the Internet creates
packets out of the data it
wants to transmit.
 Each packet has an address
and some contents. The
routers on the Internet are
like the switches in a
conventional telephone
network in the way they
control the traffic.

 They examine the destination address of every
packet that arrives and then they send that
packet onward to its destination using the most
efficient route at that instant.
 Each router only forwards a packet one step, to
the next router. Every packet leaving its origin
may travel by a different path to get to its
destination.

 The packets may arrive out of order. If the receiver
plays them out of order, it might be hard to
understand the speech. But VoIP devices and
software re-arrange the packets so that they are
played in the proper order.
 VoIP uses digital audio processing techniques and
add to them the Internet's method of transmission.
 VoIP is a promising technology because it allows for
the integration of voice, text, video, and other media
on the same network.

 In 2005, Skype became one of the largest VoIP
providers in the world having had over one million
people subscribe.
 On December 31st, 2008, the Federal
Communications Commission said that just over 21
million people were subscribed to a VoIP service via
telephone and cable companies such as Vonage.
 Most of the 162 million wired connections in the
United States are residential which translates into 13
percent.

 Most of the 162 million wired connections in the
United States are residential which translates
into 13 percent.
 Only 1 percent of those VoIP lines served
businesses. 141 million of these are copper wired
systems and are responsible for 87 percent of the
lines (48% residential, 39% business accounts).
 VoIP represents only a small percentage of the
landline phone subscriptions.

 There are many different VOIP although Nextiva
is the top rated provider.
 Nextiva has one of the lowest monthly rates
sitting at $21.95 and after reading many reviews
the general consensus among VoIP users is that
they love it.
 Nextivia has five star ratings across the boards in
terms of price, ease of use, and customer
satisfaction.

 CEO of a company named EFX - John Floyd, said that
after switching to Nextiva, they now have ten phones, an
automated attendant, a dedicated T-1 for internet, twice
as many employees, and that their monthly cost in
communications and infrastructure charges is still $500
less than before.
 He goes on to say that the call quality is great and his
customers are very happy regarding the ease of access
to a representative.

 Saves a great deal of cost to communicate within
and outside of the company.
 Since a VoIP service uses bandwidth through a DSL,
3G or Wi-Fi IP, the need for telephone wires and the
like are unnecessary.
 Being compatible with networks using 3G and Wi-Fi,
make VoIP services very portable, meaning that you
are able to use these services on your internet
phone, smartphone, laptop, and even your tablet on
the go.

 Connections can be made PC-to-PC, PC-to-
phone, PC-to-tablet and so on. Skype has
recently developed an application for Android OS
making it all the more portable.
 As well as portability, VoIP services can transmit
more than one call over the same bandwidth
connection which would be convenient for a
small office operating under one IP address.

 VoIP programs rely on electricity. This is a
disadvantage because if there is a power outage, the
call will be dropped and the service will not work
until the power source is reinstated.
 If you were to dial a 911 call and could not tell the
operator your location, they would be unable to
locate you as they would be able to with a traditional
telephone or cellular phone.

 The final disadvantage is actually fairly easily fixed.
Since data packets cumulatively contain a single file
and since VoIP services run in real-time, the data
packets risk being jumbled or misplaced if the server
is too busy. However, as stated, this can be easily
mended by creating dedicated data paths for
individual calls.

 There is a bright future lined up ahead for VoIP.
 Many companies are coming out offering
improved VoIP technology at lower costs.
 With global recession taking place, business
owners are becoming more attracted to the
commercial advantages of using voice over IP
services.
 VoIP providers can offer services 30-60% less
over traditional communication services.

 There is a higher level of acceptance towards
VoIP developing as it is being used more and
more in businesses and households.
 This is due to the fact that word of mouth is
getting around about the advantages and cost
savings in VoIP, especially in long distance
communication.

 In the near future there will be a new level of innovation
and integration between VoIP and web-based
applications.
 Example: ability to add telephony functions to your TV.
When you receive a phone call at home, the TV will
pause the live broadcast and show you the details of the
caller and allow you to accept it or send it to voicemail by
using the remote control.
 Example: “lone-worker” application which can allow a
supervisor to contact each employee on their mobile
phone to display location and safety status of employees
working alone.

 VoIP has evolved a long way from its beginning
to the underlying technology for just about all
new voice communication services today.
 As more opportunities of VoIP service integration
are explored we will see a great deal more of
VoIP in the years ahead.
