Acronym for Voice over Internet Protocol. It is a technology that allows vocal connections, sending messages, file sharing, chat sessions, conference calls, video calls and more via Internet connection. VoIP technology requires various protocols, with LEVOIP we use SIP and H.323 protocols and Codec that allow audio communications of superior quality. VoIP requires upstream band and we suggest a symmetric Internet connection or asymmetric but with upstream band over 56 Kbit/s.
