splicing phone lines

recently replaced some drywall and relocated my wall phone line. The grey phone line is a bit to short and I wanted to splice a extension onto the short line. I bought some new phone line to try and splice it together. Not sure how to do this. The old phone line sticking out of the wall is only 1 inch long. I heard about the scotchloks.? Is this what I should use. Or should I just wire them together myself and tape them together ????
