In Voice over IP or VoIP, the Internet or any other IP network is used to transport voice. This enables telephony on data networks and the possibility of merging the formerly traditionally separated worlds of speech and data. As a result, only one infrastructure is needed and new products and services can also be developed. Working with VoIP-based telephone exchanges has now become commonplace within companies. The term VoIP is often falsely used to point to the actual transfer of votes rather than to its protocol.
