A telephone directory system includes an interface adapted for connecting to a subscriber line of a telephone network (e.g., a local loop.) A dialing signal decoder receives a dialing signal from the interface to provide dialed number information such as DTMF signaling generated by a telephone used to initiate an outgoing call. For incoming calls, a calling number identification decoder (e.g., caller-ID or ANI device) receives a calling number signal from the interface to provide calling number information. A controller processes the dialed and calling number information and, in response, issues a query to a remote database for information associated with at least one of the dialed and calling number information. A memory may be used to store a directory including the dialed and calling number information together with any associated information such as the names of the called and/or called parties associated with the stored telephone numbers.
