Abstract
A caller identification displaying method in a key-phone system includes the steps of generating a ring signal if there is a ring received from an office line, and receiving and registering a caller identification during a pause period of the ring signal, requesting a password if a caller identification key is input, and displaying the registered caller identification information if the input password corresponds to a registered password. Therefore, after receiving and storing a caller identification for an abandoned call for the pause period of a ring signal, when an office line caller gives up a call after a ring is received from an office line, if a subscriber presses a caller identification key for verifying the caller's abandoned number, the caller identification for the abandoned call is displayed. Therefore, it is possible to recognize a telephone number of the caller who abandons his or her call. In addition, the recognized telephone number can be automatically dialed only by pressing the dial key without manually dialing digits of the caller identification.
