Abstract: A virtual private communications network (VPCN) and method of managing calls on the network. Communications devices are networked together over a private communications network. Each VPCN communications device has a unique private network identification (ID) code and can be contacted by dialing its respective ID. At least one of the VPCN communications devices is a wireless communications device, e.g., a cell phone, connected through a public wireless network to the private communications network. Calls to and from each such wireless device pass through the private communications network.

Abstract: The invention is directed to methods (and corresponding apparatus) for accurate transmission of an ELIN/callback number from an emergency caller after the emergency call goes on-hook. The methods include (upon initiation of an emergency call) the steps of storing an emergency location identification number and/or callback number in a buffer; and, upon detecting an on-hook event, transmitting the ELIN and/or callback number from the buffer. According to a preferred embodiment of the invention, the emergency call is disconnected after said step of transmitting; and prior to said step of transmitting, optionally first over private network and to the public network PSAP, a timer is initiated. The step of disconnecting is performed after the timer expires.

Abstract: Methods according to preferred embodiments of the present invention include establishing a licensing component on a plurality of servers, where each licensing component has a count of licenses. Each server is in communication with at least one other server on the network. When a server requires more licenses than are available according to its count, it sends a request to the other servers via the network. A server with surplus licenses responds to the request and supplies the requesting server with additional licenses. Further aspects of the invention include systems, software license models, and methods for implementing flexible software license models, which may utilize the aforementioned methods of the present invention.

Abstract: Methods for accurate transmission of ELIN/callback number from an emergency caller calling from behind a PBX/MLTS include prioritizing the emergency call, assigning a port equipment number to each device/trunk of the PBX/MLTS and associating ports/devices with ELINs and callback numbers. The apparatus of the invention detects an emergency number, assigns the call priority, and uses the port/device number to determine the ELIN/callback number and properly transmit the ELIN/callback number.

Abstract: A method and apparatus for automatically handing over calls between a wireless LAN and a non-WLAN, with minimum or no disruption of active calls. The invention gives users flexibility in customizing hand-over preferences and allows telephony features to be transferred during the hand-over.

Abstract: Systems for dialing an emergency telephone number from a teleworking client according to the invention include apparatus that implement the steps of detecting at a teleworking client when an emergency number is dialed, disconnecting the teleworking client from the PBX/MLTS, connecting the teleworking client to the PSTN, and dialing an associated stored number. Though the invention is described with reference to a teleworking client, it may also be applied to any other dialup network connection.

Abstract: A two-way pager alarm system for a home or business that reports to a security monitoring center in a wireless fashion. The alarm system, when required, initiates communication with the security monitoring center through the existing base station network that supports the two-way pager's communication, thereby transferring an alarm condition message to a distant security monitoring center with minimal transmission power. The message to the security monitoring center contains an individualized code which identifies the owner of the alarm system and also contains additional information, such as the alarm condition. The communication between the alarm system and the security monitoring center is based upon a two-way paging protocol such as ReFlex.TM.. At the security monitoring center the message is received and translated by a computer into specific information pertaining to the alarm system.
