Ringing is assigned in system programming, so if your phone doesn't ring you can't change that unless you have person on site who works on the system at that level. Some places use the night mode feature to make certain phones ring in day mode, and others to ring in night mode. Not very likely but sometimes the mode gets switched at places who don't realize they have another mode, suddenly only 2 phones ring instead of ...5. Feature,80,Feature, is the code to switch back and forth on a Pro II, an Elite, and an IPK system. This would be done at the reception phone.
