ABSTRACT:
The cellular call redirection system enables a subscriber to redirect all incoming calls directed to the subscriber's cellular telephone to an automated message system for a predetermined period of time. In addition, the calling party is connected to a voice announcement system which plays a message to the calling party to inform the calling party that the call has been redirected and provides information regarding the time remaining before the call redirection feature is automatically deactivated. This provides the calling party with an indication of the future time at which the subscriber is likely to be available to receive incoming calls. In addition, the cellular call redirection system maintains a count or queue of redirected incoming calls to thereby enable the subscriber to determine the number and identity of the calling parties who have attempted to contact the subscriber during the period that this feature has been activated.
