A telephone set and method for controlling what calls are forwarded to the telephone set. The telephone set has a terminal processor having an internal memory in which are stored a control program and data. The terminal processor under control of the program controls operation with respect to forwarded calls using the data. In response to the data, the terminal processor can block all forwarded calls from all other telephone sets, from a predetermined list of telephone sets, or from all telephone sets except for a predetermined list of telephone sets. Call forwarding can be blocked from a single forwarding telephone set not known to the user of a telephone set by the user actuating a button during a forwarded call being processed from the forwarding telephone set. In addition, the terminal processor can block all forwarded calls except those from other designated telephone sets.
