Voice over internet protocol (VoIP) is the latest technology that uses fast broadband internet connection to make voice call and not the traditional phone line. Some VoIP services only allow to call anybody who has avails the same services, but with others, people can call anywhere including traditional phone line, mobile phone, and international call. Further, some services only works with computer or special VoIP phone while others can function by using the traditional phone with VoIP adapter. There are certain equipments which are required to use VoIP such as a fast internet connection, a headphone with mike, need for other equipments shall vary as the service provider requirement. Some of them give special modems/adapters while other only connection.Such a complex product technology,perhaps this is more difficult than a simple understanding of Sony VGP-BPS13a.So have you heard of so high-class products?

VoIP is a term that you may not have heard of, but will become very common over the coming years. Voice over Internet Protocol (VoIP) is a technology that enables the transmission of voice over an existing IP network (such as "the Internet" or a local network). Simply put, VoIP is a way of converting the analogue signals when using a phone to a digital format (across a network) and then back into analogue at the receiver. This means you can have free calls to other VoIP users if you are both connected to the internet or an internal network.Simply speaking,your Sony VGP-BPS2 is a tangible product,you can say VoIP is a invisible product.

If you are using released on a free transfer software for the PC and receive VoIP calls, you'll probably be able to communicate with other VoIP users. The advantage here is that it is completely free (other than your normal Internet connection), but with a limited number of other VoIP-only connections.Though it's limited of free,but to all of the Sony VGP-BPS13b,it already very affordable.But there are trade companies, as the bridge between VoIP and traditional PSTN phone lines (regular telephone network). This type of company can charge for their services are, to call a regular phone number, but it is likely to be a very low rate of normal loads.

Broadband-based VOIP services to homes and businesses can include added features such as click-to-dial and a choice of area codes. Call quality on VOIP has also improved significantly, according to TeleGeography. However, the Washington, D.C., research company said new features and quality aren't the main motivations for international VOIP. Most international VOIP calls are made to countries in the developing world, using conventional phones, in order to bypass regulated termination charges for circuit-switched calls. VOIP is only used to transport calls from one traditional network to another, said Patrick Christian, an analyst at TeleGeography, a unit of PriMetrica.

This shows that VOIP is a good choice for people.
