    Abstract: 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.

    Abstract translation: 一种使用虚拟电话的电话通信系统，其中电话交换机或类似数字交换设备，数字电话以及诸如个人计算机（PC）或其他处理器的外部设备通常接口。 虚拟电话通用接口是可配置的，并且包括一组虚拟电话数据结构，内部和外部虚拟电话应用程序接口以及外部传输协议。 指定抽象层的软件提供内部虚拟电话应用程序接口，电话交换机和电话机之间的通信。 通用接口将专有电话交换机或外部应用协议转换为通用格式，并用作专有交换系统协议和各种应用协议之间的协议解释器。
