Pink Box Plans

Pink box allows you to hook two separate phone lines together to have three way calling with hold on either line, and well as bringing a dial tone into the conversation woth someone and allowing them to dial the number touch tone, and it will connect three way, and when they hang up, it will disconnect three way calling, no more playing with the hook for 3 way!!!
