Image Number 4 for United States Patent #6795537.
A system for and method of updating a database over a telephone network wherein a caller enters a number and the database is searched for that number. If the entered number is found as an entry in the database, that entry is deleted from the database. If the entered number is not found to be an entry in the database, the entered number is then added to the database as a new entry. The caller is given an opportunity to confirm whether the entered number should be deleted or added, as the case may be. Interactive voice response may be implemented to aid a caller through the simplified database updating process.
