VoIP or voice over Internet Protocol is a technology that ensures voice calls using a broadband Internet. It converts the voice into digital signal, which then travels over the Internet. If the call is to a regular phone, then the signal is converted into a regular telephone signal. VoIP ensures direct calls from a computer, VoIP phone or land line connected to special adapter.

There are several reasons, which have made VoIP an extremely popular mode of communication amongst the masses. First and probably the most important reason that can be thought of is the cost effectiveness of VoIP. This is perhaps the biggest charm, which is forcing people to go for it. Its impact is greatly felt in toll calls where there is virtually no expense unlike the conventional PSTN calling, which is extremely costly. VoIP also ensures that local as well as international call rates are also slashed to a great extent while regulatory fees show a sharp decline.

VoIP also offers enormous flexibility to the user. It can be carried to anyplace where access to Internet protocol is available. It can be a portable ATA (Analog Telephone Adapter) with a regular phone or a wireless VoIP phone and WiFi network, or a configured laptop for soft phone.

Another major advantage of VoIP is the fact that same network that carries data packets also carries VoIP packets, which not only eliminates useless network hardware but also effects fast and cheap changes and add-ons to VoIP system.

Wit so many advantages to offer, it should not come as a surprise to anyone that VoIP service is fast becoming popular amongst masses.
