Abstract: A virtual private branch exchange (PBX) system that routes calls within a packet-switching network. Login information is received from a data device. The login information includes an alias identifying a user at the data device and a network address identifying the location of the data device on the packet-switching network. The virtual private branch exchange system associates the user's private branch exchange extension with the network address and routes calls to the user's (PBX) extension to the data device on the basis of the network address of the data device.

Abstract: A system and method for routing a telephone call on a PSTN network to a data device. The present invention utilizes an automatic call processing system that has a one number location service. A called party provides a calling profile that is stored in the automatic call processing (ACP) system. When a call is placed to a telephone number that is assigned to the called party, the call is routed to the ACP system. The ACP system calls each of the numbers of the calling profile for that called party until that party is reached. At least one of the destinations in the calling profile is a logical address for a data network. The automatic call processing system recognizes the logical address and queries a directory to determine if an IP address has been registered in the directory for the logical address of the called party.

Abstract: A cross-stick boomerang has its leading edges or trailing edges substantially aligned. The outermost portion of each blade extends farther to the rear than does the general line of the trailing edge. In one version, an inner fin is provided inwardly of the outer fin, and in another version the hub portion is enlarged to provide a generally circular shape.
