You are not allowed to cross the end line before the ball leaves your hand. Also, you're not allowed to catch the ball if you make a bad toss. You have to let it drop before the ref issues you a redo.

This is a rule that recently has been altered. A portion of a player's foot may cross the center line if it does not interfere with play. If the whole foot crosses the line or the portion that crosses the line interferes with play the opposing team is awarded a point.
when more than the allowed amount of players cross the midfield line
Whoever answered this initially was wrong. In indoor volleyball a block does not count as a contact, but in outdoor beach volleyball it DOES count as a contact. This is one of the only incidences in which indoor and outdoor volleyball differ in rules (the only other major difference being that players can cross under the net as long as they aren't interfering with the other teams play). The person blocking is still allowed to hit the ball afterwards for the teams second contact however without it counting as a double hit. I got this from the rules and regulations listed in the FIVB website, which is the international federation for volleyball so it's a rather credible source.
That could mean a couple of things. On a pass play, offensive lineman (center, guard, tackle) are not allowed to cross the line of scrimmage prior to a pass crossing the line of scrimmage. This infraction is called ineligible man down field. On a punt, the only players on the punting team allowed to cross the line of scrimmage prior to the punt are the two players positioned on the end of the line. Should any other player except for those two players cross the line of scrimmage prior to the punt, the infraction is called ineligible man down field.
down the line and cross court
its a sport. A cross between basketball and volleyball on a trapoline!!
It is generally not allowed to pass or cross the center line within 100 feet of an intersection. This is to ensure safety and prevent collisions with vehicles entering or exiting the intersection.
