At a second unit (22) the signal is received, and the information is extracted from the signal, before any telephone call connection is completed. The signal comprises one of a multitude of assigned regular telephone call numbers or alternatively one of a multitude of different ringback tones, which are sent in response to a calling from the second unit (22). The system may be used for location and status reporting from vehicles to a central platform, meter reading, status reporting from vending machines, paging devices, etc.
