How the call is made
- Identify whether the correct player is serving in the correct rotational order.
- Freeze the receiving and serving teams at the instant of service contact, not a second later.
- Check relative position: each front-row player must be closer to the center line than the corresponding back-row player, and each right-side player must be farther right than the middle player, who must be farther right than the left-side player.
- If those relative relationships are legal, there is no overlap fault even if the spacing looks odd.
- Once the serve is contacted, players may move and cross into their preferred offensive or defensive positions.
