In September 2005, Dictaphone sold its IVS business outside the United States to a private Swiss group, who formed Dictaphone IVS AG (later Calison AG) in Urdorf, Switzerland and developed "FRISBEE", the first hardware-independent dictation-management software system with integrated speech recognition and workflow management.
Although Urdorf railway station takes its name from the adjoining municipality of Urdorf, it is actually located just within the boundaries of Schlieren, and is a stop on lines S9 and S15.
