When a crew can't reach a call...

for #2, take a page from Football's instant replay. Runner going down sideline, official whistles that he's out of bounds at the 50, turns out he wasn't. What happens? Ball's dead at the 50, once the whistle killed the play, it's not reviewable, since no matter the outcome, the ball would be dead at the 50. Same in baseball, once it's called foul, the ball's dead. Play's over, tell the coach to move on and if he won't, tell him he won't be around for the next blown call.
