Phone management server for use with a personal computer LAN
First Claim
1. A method of providing phone management functionality to a personal computer (PC) or minicomputer forming part of a PC network, the method comprising the steps of:
- (a) bridging an appearance of a voice terminal disposed near the PC and forming part of a separate network to a first port of a phone management interface interconnecting the PC network and the separate network, the separate network including call processing means for handling bidirectional call processing signaling messages associated with the voice terminal and the phone management interface;
(b) bidirectionally transmitting call processing signaling messages that are associated with the voice terminal between the call processing means of the separate network and the first port of the phone management interface using a first phone management protocol;
(c) bidirectionally transmitting call processing signaling messages between the PC, of the PC network, and a second port of the phone management interface using a second phone management protocol; and
(d) translating the call processing signaling messages received at either one of the first and second ports of the phone management interface between the first and second phone management protocols, and routing the translated call processing signaling messages from the phone management interface to the destined call processing means of the separate network or the PC of the PC network.

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.

3. Apparatus for providing phone management functionality to a personal computer or minicomputer (PC) forming part of a first network including only PCs, the apparatus comprising:
-
a second network which is separate from the PC network and is capable of providing phone management call processing functions to associated end users, the second network including a plurality of voice terminals, where one of the voice terminals is disposed near the PC of the first network being provided with the phone management functionality, call processing means which is connected to the plurality of voice terminals for handling bidirectional call processing signaling messages associated with the voice terminals; and a phone management server interface interconnecting the first and second networks, the phone management server interface comprising, a first port to which is bridged an appearance of the one voice terminal from the second network for both receiving call processing signaling messages from the call processing means and transmitting call processing signaling messages to the call processing means using a first phone management signaling protocol; a second port to which the PC is connected through the PC network, the second port being arranged to both receive call processing signaling messages from the PC and transmit call processing signaling messages to the PC using a second phone management signaling protocol; and means (1) for translating the call processing signaling messages received at the first port in the first phone management protocol into the second phone management signaling protocol and routing the translated signaling message to the second port and then to the PC of the first network, and (2) for translating the call processing signaling messages received at the second port in the second phone management signaling protocol into the first phone management signaling protocol and routing the translated signaling message to the first port and then to the call processing means. - View Dependent Claims (4, 5)
