    Patent number: 5530931
    Abstract: A method and apparatus for providing an enhanced Call Forwarding Don't Answer feature is disclosed. When an originating address calls a base address assigned the Call forwarding Don't Answer feature and the call is forwarded to a remote address, a Look Ahead feature is implemented. The Look Ahead feature determines if a call setup to a remote address is successful, unsuccessful or points out a feature assigned to the remote line.
