VoIP or SiP telephones look very similiar to normal telephones, but they connect to the data network rather than to a standard PSTN line. Voice calls are converted to data and carried over the internet, rahter than over traditional copper wires. VoIP, or Voice Over Internet Protocol is a general term for routing voice calls over the internet, where as SiP (Session Initiation Protocol) is an open standard protocol that has become a standard for the majority of unified Communications equipment manufacturers.
