Call forwarding in the phone tools does not work.

Call forwarding in the Phone Tools does not work. I cannot turn on forwarding. I get the dreaded "Try again" message when I hit the On/Off button.  I've contacted "Support" three time.  Each time I've guided them to the issue.  They diddle around and finally agree that it doesn't work, assign a incident number, send it up the tech ladder, never to be heard from again.

If you don't want to fix it, please get rid of it.
