DND light notification on Aastra phones

I have aastra 9133i’s around the office and one 6757i. Is there anyway to get the red light on the top right to turn on + have the screen say DND while its activated? Right now when I press *76 I only get a audio conformation. Im a newbie and I read I possibly need a aastra xml loaded. Ive programed all the phones the way I wanted but this is the last thing I wanted.
