ABSTRACT:
The present invention relates to a technique for providing phone management (PM) services to personal computers (PCs) which are end users of a PC-only Local Area Network (LAN) by logically associating voice terminals of a separate voice and data Network, e.g., a Private Branch Exchange (PBX), with the PCs. To provide the PM services, a PM server device is provided as an interface between the PC and PBX Networks onto which are bridged appearances of the logically associated voice terminals. The PM server device includes hardware and PM server application software that perform routing and translations between (1) PM messages of the PC-LAN which use a first PM signaling protocol, and (2) PM messages of the PBX which use a second signaling protocol. Each end user PC of the PC-LAN that is logically associated with a voice terminal on a PBX network includes PM user application software that provides a PM user interface and terminates the first PM signaling protocol. Typical PM services that can be performed at the PC are displaying calling/called party identification, retrieving and displaying messages on the PC screen, and placing voice calls from a PC-based directory.
