Voice over Internet Protocol (VOIP), is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular (or analogue) phone line.The practical upshot of this is that by using some of the free VOIP software that is available to make Internet phone calls, you are bypassing the phone company (and its charges) entirely. In addition, the quality of VOIP is good.Your voice is digitalized and transported over the Internet as well as over the phone company's private network using Internet Protocol (IP) service. A broadband phone call happens in real time. More than likely you receive many VOIP phone calls in the course of a week without realizing it. This is because the phone line quality for VOIP is the same if not better than the traditional phone services.

Number portability. This allows you to keep the same telephone number you had before subscribing to the Internet-based plan.No Regulatory Fees. Currently, there are no regulatory fees or special taxes with Internet phone call service. This give you instant savingsEmergency reliability. As your VOIP works via cable of DSL,you are hardly tracked in emergency which may cost liveswhen your connection got cut up during 911 calls. Despite of the down sides, VOIP is getting more attention because it could be applied to almost any voice communications requirement, ranging from a simple inter-office intercom to complex multi-point teleconferencing/shared screen environments.
