Quite regularly my iphone 5 on Virgin Australia will not ring or even register a missed call. I have good reception and do not have call divert on. It just doesn't seem to be connected. it seems that if I go to settings - network selection and turn automatic off , then on. the phone gets one call. then if I call again nothing happens. I've repeated this several times using two phones and everytime i turn the auto off then on i can receive one call.
