CF = Call Forwarding
Contents
Erläuterung
Die Anrufumleitung ist ein Leistungsmerkmal, das vor einem eingehenden Anruf eingerichtet und aktiviert werden muss.
Man unterscheidet zwischen CFU (Call Forwarding Unconditional, Umleitung sofort, alle Anrufe umleiten), CFB (Call Forwarding Busy, Umleitung bei Besetzt) und CFNR (Call Forwarding No Reply, Umleitung bei nicht Melden, Umleitung nach Zeit). Bei CFNR kann in der Regel die Zeit oder die Anzahl der Ruftöne bis zur Umleitung eingerichtet werden.
