  • Patent number: 8275113
    Abstract: A method is disclosed that provides the sharing of a station-mapping description with a first private-branch exchange, where the description has been initialized and maintained at a second private-branch exchange. Such a description describes a logical association between a station extension of an enterprise deskset and a telephone number of an off-premises terminal, such as a cell phone. As a result of the sharing across private-branch exchanges, an incoming call from a second employee's cell phone can be recognized, by a first employee being called, as coming from the calling second employee. This is because the incoming call is identified with the telephone extension of the calling employee's deskset terminal in spite of the call being placed from the cell phone, or other telephone number at large. This is particularly important where a large company engineers its enterprise's telecommunications system across multiple private-branch exchanges.

  • Patent number: 8213594
    Abstract: A method and apparatus for reducing the cost of long distance phone calls is disclosed. Accordingly, an originating phone network is operatively connected to a first intermediate point, and a receiving phone network is operatively connected to a second intermediate point. Each intermediate point is operatively connected to communicate via a data network. Users on the originating and destination phone networks may communicate based on virtual numbers. The virtual number is preferably within the local calling area of the originating phone network. The first and second intermediate points route calls to any geographic location, regardless of distance, over the data network based on the virtual number. This provides the advantage of allowing a user on the originating phone network to access a user at a distant location for a price that is substantially similar to the price of a local call.

  • Patent number: 7020265
    Abstract: The invention relates to a method for transmitting information such as fax, voice or data to a destination information device via a dynamic transmission network. The dynamic transmission network includes one or more transmission control servers (TCSs) and one or more transmission client nodes (TCNs). The TCS is always connected to the computer network, while the TCN is dynamically connected with the computer network. When connected to the computer network, the TCN checks its system status and then registers to the TCS. After getting the information from the TCN, the TCS stores said information into a dynamic transmission route table, wherein the information includes the country code, area code, Client ID, IP address, etc. of the TCN. Once any user requests the TCS to send a information to a destination site, the TCS will locate an available TCN physically nearest to the same country code and area code as those of the destination site, and then transmits the information to the TCN through the computer network.
