"Make telephone calls anywhere in the world absolutely free of charge."

Does this sound as an exaggerated claim? A promotional gimmick?

Well, today, it is actually possible to talk to your near and dear/ your customers and business associates absolutely free (or with a nominal calling charge). With the latest VoIP technology sweeping the arena of telephony, talking free of cost is no longer a long-cherished dream. It is a hardcore reality!
VoIP is indeed a revolutionary technology that will eventually change the face of the existing telephony system.

What is VoIP?
VoIP (Voice over Internet Protocol) is a technology that is used to transmit voice or audio files over the Internet via a packet-switched network. The voice/audio files can be received by:

• a computer


• a VoIP phone


• a standard telephone

The VoIP technology enables the transmission of voice/audio data as digital data over the Internet.

A number of practical applications based on the VoIP technology are gaining popularity among people as a means of economical communication. They are:

• VoIP phones

dedicated instruments to make calls over the Internet

• ATA sets

telephone-like boxes that connect to a computer and convert the analog voice data into digital signals

• computer to computer calls

need a computer system, headsets and Internet connection

phones are slowly gaining foothold in the market due to their efficiency in meeting the financial and infrastructure needs of corporate houses. These phones are also known as 'broadband phones' as they can be used to make calls over the high-speed Internet connection.
A VoIP phone converts voice data into digital data so that the data may be transmitted over the Internet. You need to connect the phone to a computer to enable voice communication.
VoIP phones look just like the standard telephones with the cradle, the buttons and the handset. So, you can make calls in the usual way...but with better sound quality and in an economical manner!
