I've had this problem for about a week or so.
My iPhone 4 keeps hanging up when people call me, it rings for about one second
then it automatically takes them to voicemail.

I've tried to restore the iPhone to its original settings, and i've tried updating and changing sim-card.

My operator is Telenor from Norway.
