VOIP or Voice over Internet Protocol, basically means voice transmitted over a digital network. Essentially, what happens is that you use your high-speed internet web connection for better telephone service. The calls are routed to the internet rather than over the telephone lines.
The computer is not required, but network resources are required. The same protocols or rules that are used for sending data over the internet are used for sending voice transmissions.

Data is usually sent over the web in packets. With VOIP, these packets also include both the sender's and the receiver's MAC or Media Access Control address, along with the voice signal.
Advantages of VOIP
There are many advantages of using VOIP over traditional POTS or Plain Old Telephone Systems. VOIP can be used to make free phone calls.
- Because VOIP uses packets, more information can be sent over the network. The data can be compressed, which now uses less space and time, resulting in lower transmission costs.
- More dynamic routing to other routes if the selected route is unavailable.
- VOIP works over all kinds of networks, and with any IP-enabled device such as iPhone, iPads, and others.
- VOIP is much faster
- VOIP can integrate all other forms of communications including videoconferencing and audio streaming.
- VOIP runs on computer lines and no other additional lines are required.
