VoIP stands for “Voice-over-IP” and defines voice communication via internet-based networks. This forms the technical basis for IP telephones.
VoIP has opened up many new possibilities for telecommunications and replaced traditional telephone systems, which still established connections via the copper cables of the fixed network. The function of Voice-over-IP involves the transmission of voice data via the Internet instead of using traditional telephone systems. The Internet Protocol (IP) was initially only developed for the transmission of data packets in computer networks. However, IP became established as a standard, which meant that it was also used for data packet-based transmission of voice information. The advantages of VoIP are, for example, the simplification of telephony processes and the enabling of new services and functions, which would otherwise be very costly. Voice-over-IP is also easy to install, configure and manage.
Voice-over-IP has thus significantly changed conventional telecommunications, as it offers a cost-effective and flexible way of providing voice communication and multimedia services. It is widely used, especially in companies and for private communication.
