INTEGRATED CALLING DIRECTORY

Integrated Calling Directory The integrated calling directory of the present invention eliminates the disadvantages of prior call directory arrangements by providing a software system which runs on a personal computer to automate the call directory and call origination function. The personal computer is interposed between an individual's telephone station set and the business communication system port circuit associated with the individual's telephone station set. The calling directory software both contains the individual's personal directory entries and has access to directory entries in the centralized business communication system data base which resides on an adjunct processor. These directory entries all contain called party identification data which includes information such as an individual's name, room number, electronic mail address, telephone number, type of terminal equipment associated with the called party, job title, etc.
