VoIP is useful for each of us, whether we are working in a professional set up or we are at home. It is helpful for both individuals as well as corporate organisations. VoIP has many benefits, that can make our communication not just quick and smooth, but also quite cost effective.

VoIP or Voice over Internet Protocol, is nothing but communication with the help of internet. For this, all you need is an internet connection, a phone that supports VoIP and a PC. First of all you need a service provider, who would give you internet connectivity. With the help of internet, you can make calls to anywhere in the world. These calls are known as Web Calls. You can make both voice calls and video calls.

For a VoIP based call, you need a telephone that supports VoIP. The market is flooded with VoIP phones from various brands. There are brands like Philips, Siemens, Plantronics, Panasonic and Linksys – the devices manufactured by such brands are gaining high popularity among the masses. These brands are easily available through web stores. The main reasons for such growing popularity are – the cool features that they offer and the immense benefits that VoIP phones have.

Now let us briefly look at some of the major benefits that VoIP offers to its users. First of all, VoIP makes communication extremely smooth and very fast. There is superb clarity in the sound and in case of video conferences, the streaming of video is of excellent quality, unlike web cams.

So how do calling cards work? There are two main kinds of cards: free and paid-for. Free cards have a premium rate phone number on that you then call and enter your card number and PIN number. The premium rate phone call pays for a certain number of minutes for you to the country of your choice. Paid-for cards work similarly with the card number and the PIN, except that you buy them in a shop instead of paying with a premium rate call.

The reason your calls can be so much cheaper than usual when you use a calling card is that they are no longer being routed through the normal phone network. Instead, calling card companies are free to construct their own international telephone networks, often using advances in technology to their advantage.

Most modern calling cards actually route calls over the Internet, which means that an international call in fact becomes only a local call at each end, with the Internet acting as a ‘bridge’ between the two phone networks. This means that the calling card companies can make a lot of money for very little work, while also providing a much cheaper service than usual to the customer.

If you want to cut out the middleman, though, you might consider using a voice-over-IP service on your computer, such as Skype. This allows you to make calls for free over the Internet, and at local rate to landline phones all over the world. While you have to have a computer and Internet access and use a headset instead of a phone, the calls are a lot cheaper than even the cheapest calling card.

With the advent of calling cards, it's easier to be in touch with the relatives and friends living abroad. These cards are simply a pre-paid card and could be easily bought from different online shopping portals.

Before selecting any phone card check the phone rates, reliability, hidden fees, rollover minutes and quality of call offered by the calling card providers.
