Voice-over-Internet-protocol (or VoIP) is a way of communicating with other people through the Internet using voice transmission over a protocol. VoIP is commonly used to describe the concept of the transmission of voice over the Internet, as opposed to the protocol that carries the transmission. In Twinity, users or members can speak to other avatars using VoIP technology, if the user´s computer is enabled with VoIP capability (Internet broadband connection, microphone and headset). Just like using the telephone, Twinity members can use VoIP to speak in real-time to other members of the 3D virtual world, independent of location and the physical restrictions of space. VoIP technology is not only used to transmit voice, but can also carry compressed digital audio or video signals (such as mp3s or video conferencing) from user to user.
