A preferred embodiment of the present invention includes a call blocking service to which a user subscribes. The preferred call blocking service includes maintaining an updateable list of calling parties that the user wishes to block from being able to complete telephone calls to the user, maintaining a buffer for storing information associated with the most recent calling party placing a telephone call to the user, and recognizing a signal that the user activates to automatically add the most recent calling party to the list of calling parties blocked from being able to complete telephone calls to the user.
