Abstract
A system and method for reducing unwanted telemarketing calls may include storing a contact list for users of a telephone assigned to an associated telephone number. An incoming telephone call from a caller may be intercepted and a determination may be made as to whether the caller is in the contact list. In response to determining that the caller is in the contact list, the incoming call may be connected to the telephone assigned to the called telephone number. Otherwise, in response to determining that the caller is not in the contact list, the caller may be prompted with an audible message, and, in response to the caller responding to the audible message by entering a first response, the incoming call may be blocked from connecting to the called telephone. Otherwise, in response to a second response, the incoming call may be connected.
