A telephone communication system utilizing a virtual phone wherein a telephone switch or similar digital switching device, a digital telephone and an external device such as a personal computer (PC) or other processor are generically interfaced. The virtual phone generic interface is configurable and comprises a set of virtual phone data structures, internal and external virtual phone application program interfaces, and an external transfer protocol. Software designated an abstraction layer provides communication between the internal virtual phone application program interface, the telephone switch and the telephone set. The generic interface converts proprietary telephone switch or external application protocols into a common format and functions as a protocol interpreter between proprietary switching system protocols and protocols of various applications.
In a telephone communication system comprising at least one telephone switch, at least one telephone and an external application device, a virtual phone interface comprising:
A method for representing features of any type of one or more digital telephones independent of the type of telephone switch operatively associated with said one or more telephones and independent of the number of features in said one or more telephones comprising:
A method for representing features of any type of one or more digital telephones independent of the type of telephone switch operatively associated with said one or more telephones and independent of the number of features in said one or more telephones comprising:
A computer readable memory device encoded with a data structure for providing a virtual phone generic configurable interface serving as a protocol interpreter of the protocol of a telephone switch and converting the protocol of the telephone switch and the protocol of an application associated with the operation of said switch and a communication device for enabling communication between the telephone switch and the communication device, the data structure having entries wherein each entry contains a representation of the state of the communication device as known to the telephone switch at any given time.
