A method and apparatus for automatically collecting data from a remote location includes placing a remote appliance at each remote location. The remote appliance establishes network connections by making a scheduled local telephone call to the local ISP to communicate with a central server. Virtual networks are established for the purposes of retrieving data from a remote location, consolidating data from several remote locations. The system permits the establishment of simultaneous multiple shared virtual networks using a common central server.
