A caller identification device attachable to a telephone line and having a message function includes a line interface coupled to the telephone line, a ring detector for detecting rings of an incoming telephone call, and a line monitor for receiving an incoming telephone call signal from the telephone line in an on-hook state. A caller identification detector is coupled to the line monitor for detecting caller identification information including at least the caller's telephone number when the line monitor receives an incoming telephone call signal. A speech synthesizer generates and transmits speech signals on the telephone line, and a remote detector is coupled to the line monitor for detecting a remote command tone signal. A controller activates the line interface to seize the telephone line when the ring detector detects rings of an incoming telephone call. The controller enables recording of the caller identification information detected by the caller identification detector, and causes the speech synthesizer to generate and transmit to the caller a menu of spoken options prompting the caller to enter a remote command tone signal corresponding to a message when the line interface seizes the telephone line. The message corresponding to the remote command tone signal entered by the caller and detected by the remote detector is recorded. The controller may optionally control dialing of a service such as a pager service, to transmit caller identification information and, if applicable, a message, to the pager service.
