  • Patent number: 5033076
    Abstract: This invention relates to apparatus and a method for use in conjunction with a service wherein a called telephone customer receives a display of the number of a calling telephone customer. In conjunction with this service, customers are offered a class of service and/or an option to dial a privacy request wherein their telephone number will not be displayed to the called telephone customer. In accordance with this invention, the customers are offered a class of service wherein they will receive calls only from telephone customers willing to have their telephone number displayed. If a call is made from a caller who does not wish to have his number displayed to a called customer who will not accept calls from customers unwilling to identify themselves, the caller is given a special announcement; in response to this announcement if the caller keys a special privacy override code then the call is completed with the caller's number displayed.
