Much has been talked about VoIP and
the exclusive communication facility it offers. However, using VoIP all alone
could be at times insecure since the protocol you use to communicate can be
easily decrypted. To combat such a situation, use of VPN
gives you added security over your VoIP network.
In addition there are many countries
and regions where VOIP has been completely blocked, therefore to unblock it,
VPN is needed. Let us know more about this beneficial technology, VoIP
and its effective bond with VPN.
What
is VoIP?
You would instantly raise your voice
in the favor of Voice over Internet Protocol to cite as an instant answer for
this question (we are so prompt in telling the full forms of abbreviations).
However, you may face problems in defining its real meaning except the fact
that is something related to Skype and helps you to get connected with one of
your many girl friends located abroad through voice communication.
Jokes apart, VoIP is much more than
that. Not restricted to merely Skype, it refers to an entire clan that
comprises of some of the most widely used technologies, protocols, procedures,
and techniques for successful accomplishment of multimedia sessions, heavily dominated

It is a bit intricate matter to deal with, knowing the functioning of a VoIP, still lets hope that you can grasp the next few lines. To establish connection through VoIP, you would first need a VoIP gateway router. The process thus includes:
- Receipt of voice signals through router from the other source in analog form,
- Conversion of analog signals into digital format
- Encapsulating the voice thus converted to digital format, into IP packets
- Encrypting the same with the help of IPSec
- Routing the encrypted packets via VPN tunnel in a secure manner
The same procedure is followed at
the other end with the difference that the voice received at the VoIP router
installed there converts the voice from digital form to analog signal so that
the voice message could be conveyed at that side conveniently.
Role
of VPN in VoIP
If you notice keenly, then we have
already mentioned its role in the working of VoIP. Still, to elaborate further,
VPN creates an additional tunneling layer to transfer the data packets from
your side to other after encapsulating and encrypting it through proper
mechanism through VPN Protocol. VPN
integration enables you to undergo duly secure voice communication over the
VoIP channel. It utilizes 128-bit AES technique for encryption that is
impossible to decrypt by some intruder and hence paves for its enhanced
security.
With a VPN, you get the freedom to
speak freely and unlimited without concerning about safety and security. Plus
you get to unblock Skype and other VOiP messengers in countries where it is
blocked.

VPN Service for VoIP
Almost all the topmost VPN
service providers allow flawless communication over the Voice over
IP. You can approach any of them to help your cause. However, whether they
offer VoIP services at your current location could be deciding factor to choose
the best one.
Alongside, the price considerations
should also be taken care of. Make sure to look after the log policies of
these VPN providers, your data is extremely
confidential and you would certainly want to have a VPN that could provide you
full assurance that their services are free of data logging.
