ABSTRACT:
A telephone instrument with computing means and a memory that stores a number of dialed numbers. The computing means follows a process that is responsive to the "re-dial" button of the telephone instrument and to the "#" and "*" buttons on the dial pad. The process provides a "backup" capability that points to successively older entries in the memory, thereby allowing a user to dial out older entries, and also provides a search function that searches through the memory for a specified number.
