Hi all. This morning it has come to my attention that all numbers in ACD do not work. When you call an ACD number it just sits there for lack of a better word. The correct name is displayed on the phone but it does nothing. No busy signal, no ringing, it does not disconnect; it just sits there and does nothing. The symptoms are the same when you dial any number in ACD. Any idea what could be wrong? How I could resolve this issue? I thank you for your help! By the way we have a Nortel Switch and are using Meridian Mail.
