VIRTUAL PHONE GENERIC CONFIGURABLE INTERFACE

摘要

A telephone communication system utilizing a virtual phone (18) wherein a telephone switch or similar digital switching device (12), a digital telephone (14) and an external device such as a personal computer (PC) or other processor (16) are generically interfaced. The virtual phone generic interface is configurable and comprises a set of virtual phone data structures (20), internal virtual phone application program interfaces (VPAPI) (22), external VPAPI (24), and an external transfer protocol. 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.
