Outline

Saros besitzt eine eigene Voice-over-IP-Funktionalität, die sich nahtlos in das Sitzungsmanagement einfügt. Dazu fehlen noch: Konferenzmodus, Performanceoptimierung und Benutzbarkeitsevaluierung. Im Rahmen einer X-Arbeit soll hier ein Teil dieser Funktionalität implementiert und evaluiert werden.
