Internet Telephony (IP Telephony) is the term commonly used to define the transmission of phone calls over the Internet. This is regardless of whether traditional telephony equipment, computers and/or dedicated terminals take part in the calls and even if the phone calls are totally or partially transmitted over the Internet.

One of the main reasons of this quick migration to Internet Telephony is that it makes the integration of all means of communication, communication devices and media much easier. This way users can be in touch with anyone, wherever they are, and in real time. In short, IP Telephony allows for Unified Communications to become part of the business environment, helping companies save money and boost employees’ productivity.
