Do you use "analog message waiting" line cards? If so when you leave a message on that ext. do you get the stuttered dial tone? Do you have a maintainence set with "mik" and
"mck" so you can test the light?
That's what I would do first. Out the tn of the set that don't work and copy a set that is known to work. You did put a known good set on that tn just to make sure it is not just a bad light didn't you.
