why is the phone sign displayed across the top when I'm not on the phone?

[AC Question]

The phone sign is displayed across the top when I'm not using the phone. I've only ever noticed it coming on when I've been using the phone feature. But now it's been on and I'm not talking to anyone. Can you tell me why that is?

No, but it may be a glitch. Try a Power Off and Restart.
