I have an option 61 with an acd group programmed on it. The acd number is on key 0 on 2 phones and then they have a private dn on key 1 and a phantom line on key 2. These private numbers also are scn'd on 2 other phones. They have voice mail built on their private lines. When someone calls them and leaves a message the message waiting light does not come on. I have mwa in cls and checked the voice mail programming and message waiting is turned on. I also tried to turn on the light by manually turning them on with a mck and an mik button but the lights want come on. I know the lights work because I have checked them in other spots. HELP!!!!!!!!!!!!!!!!!
