ABSTRACT:
The automated telephone directory of the present invention combines a telephone, a telephone directory and a telephone log into a single computerized unit. The primary directory database contains the directory information for an entire geographical region (i.e. city, state, province or country) and is accessed by a central processing unit to facilitate the placing of telephone calls and to create incoming and outgoing logs. Several other databases are created automatically or can be created manually to enhance the telephoning process. The system also includes the means to send and receive alphanumeric page messages. A display screen is provided to display, upon command of the CPU, the directory information of incoming and outgoing telephone calls and for displaying the various databases provided.
