To begin with, VoIP or Voice over internet protocol refers to the transmission technologies for delivery of voice communications over Internet protocol networks such as the Internet or other packet-switched networks. It is one of the most popular and convenient communication services these days. The most important advantage of using VoIP is that it allows you to make and receive cheap or free local and international phone calls provided with a good VoIP service. Here, selecting the right VoIP service provider is important. The type of VoIP service you need would be determined by the way you will communicate and your needs.

There are many types of VoIP service providers and you have to select the best that suits your requirements. Most common among the service providers is the computer based or software based providers. They are the most popular among the VoIP users. For PC to PC communication over the internet, this type of service can be used for free. The procedure for getting this type of service provider is relatively simple. All you need is to download a VoIP application that has been provided by the VoIP-service provider and install it on your machine. Then you can register for a free account and start talking. If you are chatting with people who are using the same VoIP-services on your computer, the calls would be unlimited and free. The calls to mobile phones and landlines are charged but they are really cheap. The minimal hardware required would be a headset.

The second type is the residential or office VoIP services. This type generally replaces your existing phone line at home or in office. Once you sign up for the service online, you are given a phone adapter that you can plug to your broadband internet line and the other end to your regular phone line. The calls would be charged monthly or on a once-off subscription basis. Usually these rates would be time flat. There would be unlimited local calls or calls for certain destinations. Sometimes the service would be offered for a limited number of minutes.

Next comes the mobile VoIP which is an excellent option to cut down the cost of your rising mobile communication. The mobile VoIP carries all the features of the normal VoIP and cost is also a major element that attracts people to take up the services. There is yet another category called as the no-monthly bill VoIP services. They are similar to the residential VoIP where the service would be provided using a device given by the provider. However there would not be any monthly fee involved. The device would be charged and once it is installed, you can make unlimited calls without getting monthly bills.

There are exclusive options for network centered business firms. Here the VoIP can be implied as an internal and external communication solution. They can also replace the small number of phones in a small enterprise setting. In the business VoIP-service the solutions are offered as packages that would be altered to your needs.
