 VoIP (Voice over Internet Protocol) is simply the transmission of voice traffic over IP–based networks, such as the Internet. The Internet Protocol (IP) was originally designed for data networking. The success of IP in becoming a world standard for data has led to its adaption for voice networking.
Protocols which are used to carry voice signals over the IP network are commonly referred to as Voice over IP or VoIP protocols. They may be viewed as commercial realizations of the experimental Network Voice Protocol (1973) invented for the ARPANET.ce providers. Some cost savings are due to utilizing a single network to carry voice and data, especially where users have existing underutilized network capacity they can use for VoIP at no additional cost. VoIP to VoIP phone calls on any provider are typically free, while VoIP to PSTN calls generally costs the VoIP user.
