Why does the access warning triangle appear on my Aastra Dialog 4422 IP Phone?

If you see an access warning triangle on the display of your Aastra IP Phone, it signifies a disturbance on the network or in the telephone system. While some features might not function correctly, you can still use the phone to make and receive calls.
