Missed call

Why do I get a message about a missed call when the phone never rang? Call is forwarded immediately.

Is your phone on silent or vibrate? Sorry, but that's an obvious thing to check. The other would be to ensure you have network connectivity. Maybe you didn't at the time the call came in?
