Abstract: A unified number coordinator is in a server for an internet communications app on a mobile device of a user. The coordinator includes a roaming checker which receives region of origin information from the server, in response to identification of the user of a mobile device running the app. It also receives location information of the mobile device and determines if the user is in the region of origin or in a different region. An app router receives a unified number dialed by the user, the region of origin and, if the user is roaming, the different region. The app router provides a first business and its address associated with the unified number in the region of origin and, if the user is roaming, a second business and its address associated with the unified number in the different region, for the user to select.

Abstract: A host and multiple user stations form a system that provides computer functionality to multiple users by equipping the host with a host multifunction unit and by equipping the user stations with station multifunction units. Both the host and the station multifunction units have communication units and processing circuitry. The communication unit of the host interfaces with the communication units of the user stations to enable mutual signal exchange. The processing circuitry of the host multifunction unit enables the CPU of the host to send and receive signals to and from the user stations. The processing circuitry of the station multifunction units enables signals sent from the host to be forwarded to a display unit of the user station. The processing circuitry of the station multifunction units also enables signals from an input unit of the user stations to be forwarded to the host.
