Abstract: A computer telephone integration system includes a computer integrated with a telephone system. The computer has a plurality of independent application programs that are operable thereon and a plurality of files containing data that are retrievable by any of the plurality of independent application programs. The computer also includes a plurality of first commands that are disposed on the computer to retrieve and run any of the plurality of independent application programs and a plurality of second commands to access any of the files containing the data with any of the plurality of independent application programs. The computer further includes a call processor disposed on the computer that allows a user of the system to associate the first commands and at least one of the second commands with call information received from the telephone system at the reception of an incoming call or with call information provided by a user of the system at the initiation of an outgoing call.

Abstract: A switching device independent computer-telephone integration system including a computer; an established set of telephone functions for commanding the computer; a library including a plurality of telephone switching device commands for a number of different types of switching devices; and a state machine, operable on the computer, for translating the switching device commands into equivalent established telephone functions for uniformly processing incoming telephone calls independent of switching device dependent commands.

Abstract: A rule-based computer-telephone integration system including a telephone system for transmitting call information, a computer in communication with the telephone system including a plurality of application programs having data retrievable in response to call information transmitted by the telephone system, and a call processor operable on the computer including routines for uniformly establishing precedential rules for retrieving the application program data based on call information and for automatically executing the established precedential rules in response to transmitted call information.
