Abstract: PURPOSE: A method for identifying a memory phone number of an automatic answering machine is provided to improve a convenience of using a phone set by conveniently using a memory phone number function by allowing a user to successively identify phone numbers until a registered phone number is found at one time. CONSTITUTION: When it enters from a standby state to a memory phone number content identification mode, an automatic answering machine transmits the first one of previously registered memory phone numbers in voice(ST11-ST13). A user listens to the transmitted voice and it is determined whether a stop button is depressed within a predetermined time if it is a desired phone number(ST14). If it is not a phone number desired by the user and the stop button is not depressed, the automatic answering machine sequentially outputs the previously registered memory phone numbers from the first one to the user in voice(ST15,ST16). While the registered phone numbers are sequentially outputted, if a memory phone number is identified to be the number desired by the user, a call is attempted with the identified phone number.
