The invention refers to a device for storage and signalling phone calls made between an executive and his subordinates in a company; the subordinates can send requests by operating several switches and the addressee can visually examine the calls by inspecting some LEDs (light emitting diode) that are accurately connected, each corresponding to a particular person. The electric energy is spent only when the visual inspection is made.
