VoIP or Voice over Internet Protocol, also known as IP Telephony or Internet Calling is an alternative way of making phone calls that can be less costly than standard telephone calls over PSTN (Public Switched Telephone Network).

VoIP works by taking standard analog audio signals and converts them in to digital data that can be transmitted over the internet using the IP Protocol.

This function can either be included into the VoIP itself or in a separate box like a telephone adapter (ATA).

Direct VoIP Connection

It is also possible to bypass a VoIP Service Provider and directly connect to another VoIP user. However, if the VoIP devices are behind NAT routers, there may be problems with this approach.

Applications using VOIP

Traditional telephony applications, such as outbound call center applications and inbound IVR applications, normally can be run on VoIP.

Why use VOIP?

There are two major reasons to use VoIP:

1.Lower Cost

2.Increased functionality

For a relatively new technology, VoIP has already become widely accepted around the world. There are still a lot of improvements that can be made and are expected to be implemented over the next few years.

Around the world operators are launching VoIP services if they haven’t already, and some major operators have begun to move to a fully digital service. 

It’s clear that VoIP is here and will continue to be rapidly adopted around the world.
