I want to make a phone call . Can you show me how ?   Of course , pick up the receiver , hit a button and listen for a tone . Are you hearing it ?   Yes , now what do I do ?   Well , after you dial 9 on the keypad , you should hear the tone change .   No , nothing changed .   When you dial 9 and hear the tone change it means you have an outside line . Who are you trying to call ?   I am trying to call my boss .
