I was wondering about the name too. From https://jitsi.org/what-is-jitsi/ https://jitsi.org/what-is-jitsi/ : SIP Communicator is renamed Jitsi (from the Bulgarian “жици”, or “wires”), since it now also supports audio and video over XMMP’s Jingle extensions and it would be silly to still call it SIP Communicator.
