really there isnt that much to practice if you have a box just use it and dont get caught as far as red boxing i have heard mix responses about this…try to find pay phones that are actually owned by the phone companies not the COCOTs although if you can only find the customer owned ones try finding the cable connected to the phone before it gets to the money/keypad device and strip the wries and connect your beige box with the alligator clips if you can and that should work lol hope that made sense
