If you
don’t know already then most ordinary phone numbers you have are given to you
or leased to you by network providers over the traditional PSTN – public
switched telephone. But there is another network that you should know about
that is a method and technology of the transfer of voice calls and messages and
data of communications over other networks such as Internet Protocol (IP)
networks, this is also why VoIP is called Voice over Internet Protocol network.
In common language VoIP is the communication technology that allows making
phone calls using the Internet instead of the PSTN.
Voice over Internet Protocol
Voice over Internet Protocol is the term
for internet telecommunications or IP telephony which allows for the transfer,
and receiving and making of voice calls and videos calls, other telephony
multimedia through the internet. VoIP works by sending information containing
voice information or voice data in form of data packets just like the ones sent
and received to make internet connectivity work unlike the traditional method
of Public switched telephone networks. The
biggest advantage of using VoIP and IP telephony and communication is that you
don’t have to pay for the call rates that and charges levied by network
providers. Internet telephony or IP mobile communications is the term that
usually refers to the services of voice calls, videos calls, messages etc
provided through the VoIP/public network. The protocols, principles, and steps
of telephony and transmitting the signal, digitizing the signals, coding,
encoding, etc remain the same like public switched telephone network for voice
just like Voice over Internet Protocol network with the only difference being
in the medium of transfer of voice information or data; PSTN digitizes and
transmits voice data or information through circuit-switched network. So
basically a Voip phone number has the ability to make calls or video chat
or send texts through the internet.
Popularity
This mode of network provision or calling
has become extremely popular because any person with a VoIP Phone number can
switch their network to VoIP or download particular software and applications
that work on the VoIP network rather than switching carriers. Most networks now
also provide the “on-net call” facility. This is basically VoIP network,
customers have the option to either enable their SIM cards to provide VoIP or
they can change their networks to VoIP and still be on the same carrier, the
carriers charge extremely less compared to normal PSTN call rates. This is
therefore the biggest advantage of using VoIP as your network is that you can
make calls and send texts free of cost
or extremely cheaply as long as you an internet connection, wifi or
mobile network. Many popular social media apps have free calling services that
also work on the same principles of VoIP. Other internet calling and video
calling applications, websites, services or softwares also work on the same
principle of VoIP. VoIP has many other advantages too, you can also video call
which is also available on PSTN network but is very costly. Thus VoIP networks
are the networks of the future.
