Firstly, did the ball not bounce and go out at the side of the pitch, or bounce and go out the end of the pitch. If it's the former then it would be a line out in line from where it was kicked, if it was the latter then it would be a scrum where it was kicked.
And phases are how many times the ball's been recycled. So if someone has the ball, gets tackled and recycles a ball through a ruck they would then be in the second phase.
Hope I helped, Rhys
