ABSTRACT:
An intelligent terminal (which can be a telephone, a facsimile machine, or similar device) is arranged so that (a) it can store information indicating when (e.g., date and time) a particular subscriber last was present at the terminal, and (b) the stored information can be retrieved from the terminal remotely, preferably without completing a conventional call to the terminal. A central processor contains, for each subscriber, a list of the intelligent terminals that have been pre-designated for use by that subscriber, and has the ability to query terminals on the list. In response to a call placed to the subscriber by dialing the subscriber's unique personal number, specific intelligent terminals on that subscriber's list are queried by the central processor to determine when the subscriber was last present at each terminal. The central processor then generates a control signal such that the call is then completed to the particular terminal that was most recently visited by the subscriber.
