Internet telephony
means different communication services like SMS, Fax, and Voice messaging which
are transmitted over internet rather than PSTN (Public Switched Telephone
Network). There are a number of steps involved in making VoIP calls like
signaling, encoding, digitalization of analog voice; media channel setup,
transmitting as IP packets over packet switched network etc. Receiving VoIP calls
too involve some such steps like reception of IP packets, decoding and so on.
Benefits of VoIP
VoIP was developed
with an aim of providing smooth voice communication in any part of the world
easily, quickly and cost effectively. In different parts of the world, voice
communication is very much costly. Think about making a voice call to the other
side of the globe which is thousand kilometers away. The very first thing that
comes to your mind is the cost of making that call. Right? VoIP solved lots of
problems like this. So, the most important reason VoIP is a popular form of
communication method is that it doesn’t cost much to make and receive calls. We
all know about Skype which give free VoIP services for people living all over
the world up to a certain stage.
Following are some
top benefits of using VoIP-
Cost Effective-
If it is the case
that you don’t use VoIP, then most probably you are using PSTN network which is
regarded as good old phone network. But on PSTN, you are to pay by the time.
International calls on PSTN network are way too expensive. But in VoIP, you
won’t have to pay by the minutes you talk; all you will have pay is the monthly
charge to your Internet Service Provider for broadband internet access as VoIP
uses internet as its backbone. Statistics suggests that you can save up to 90%
on international calls and up to 40% on local calls using VoIP as your voice
communication mode. Again, for VoIP calls you needn’t to have so many hardware
and software. You need a speaker, microphone and a sound card along with your
computer and internet connection. These hardware and software are generally
very much cheap. So, spending very little money, you can make local and
international calls.
Enable more than one person in conversation-
In PSTN network, we
can’t have a group of people to make voice communication together. But, these
days, people use VoIP to hold meetings in groups as it support a large number
of people to connect together.
Unlimited Useful and Interesting Features-
For both personal
and business uses, VoIP has a number of useful and interesting features.
Whatever your call destination is, you can make video calls using VoIP account.
Some other features include voicemail, Caller ID, contact list, extra –virtual
numbers etc. You can even share your computer screen with the person you are
talking using VoIP. So, it’s not only voice, many more things than only voice.
You can send text, files, folders, videos, images and so on with a few clicks
only.
Efficient Bandwidth Use-
It is found that
about half of our voice conversation is silence. VoIP tracks those silence
spaces and fills with data communication channel so that no bandwidth is
wasted. Thus, VoIP uses bandwidth more efficiently.
Flexible network layout-
The VoIP network
doesn’t require being of an exact topology or layout and enables an
organization to use some other proven technologies like SONET, ATM, and
Ethernet. Even using wireless networks such as Wi-Fi, you can have VoIP calls.
Therefore, VoIP has
made communication much easier for businesses and individuals than ever before.
If you’re yet to take advantage of such cost effective voice communication
facility, experience it today!!
