System and method for digital telephones on H.323 networks

摘要

A communications system and interface (109, 210) for interfacing a proprietary digital telephone (108, 114) to a local area network (LAN) (104). The interface may be embodied in a computer expansion card or a stand-alone unit. The interface converts signals from the proprietary digital telephone's communication protocol to the LAN's communication protocol. In a specific embodiment, the LAN communication protocol is the H.323 protocol.
