Have a Definity G3iR6 with Definity Audix (TN 566) 5- slot audix, problem is everything seems to work fine, but for some reason when you leave a message..message light comes right on at station XXX but if you clear out message light continues to stay on...eventually it might extinguish but mostly stays on..I'm sure it has to be in the set up of the Audix stations in switch but what are we missing? Any ideas...would be appreciated
