Abstract: A method of notification in a virtual receptionist system. The method begins by determining that a guest has arrived. The guest is determined without active participation from the guest. An alert is activated for each greeter in a plurality of greeters designated to greet guests. It is determined whether any greeter has acknowledged a corresponding alert. Thereafter, alerts corresponding to each greeter are de-activated when there is an acknowledgment.
