Voice over Internet Protocol (VoIP) is a protocol optimized for the transmission of voice through the Internet or other switched networks. It's described as the transmission of voice traffic over IP-based networks, a unique technology that allows us to make calls using a broadband Internet connection ( through broadband modem ) instead of a regular (analog) phone line. At first, the Internet Protocol (IP) was originally designed for data networking systems. Later, with its success in data networking field and the explosion of Internet Era, the IP has been developed in voice networking and nowadays it is bringing us the most profit in this field. VoIP has become more and more popular because of the cost advantages to consumers compares to traditional telephone networks.
