Abstract

The present invention relates to a call forwarding system for forwarding telephone calls to a target telephone not having a direct dial number. The call forwarding system includes an intelligent forwarding unit for storing a forwarding direct dial number and the extension number for accessing the target telephone and for connecting the received forwarded call to the target telephone, a voice response unit including a DTMF decoder for receiving the forwarded telephone call and for decoding the extension number of the target telephone. A call connecting unit directly connects the in-coming telephone call to the target telephone.
