Das System hat je nach verwendetem
Telekommunikationsendgerät des Teilnehmers zwischenzeitlich
durch GSM-Zellinformationen bzw. über die Zuordnung zu
einer ISDN-Vermittlungsstelle den Ausgangsort der Fahrt
(entspricht meist dem Standort des Teilnehmers)
identifiziert. Über die Sprachdatenbank 3, in der alle
verfügbaren Codes sprachlich hinterlegt sind, wird dem
Nutzer diese Ausgangsinformation vom System mit der Bitte
um Bestätigung mitgeteilt. Ist diese Information vom System
nicht ermittelbar oder ist sie durch variable Ausgangsorte
nicht relevant, so kann der Nutzer die Information über den
Ausgangsort in gleicher Weise über die Ortsnetzkennzahl,
Rufnummer oder Postleitzahl regional codieren und dem
