Press "Call free!" and select "Call" from the Skype menu. If you are not using a headset or a microphone to make a call, you have to press the "Mute" button before making the call to use the dial pad. You need the dial pad (press "Show dial pad") to navigate your way to speaking with a representative. After you have reached the representative, press the "Mute" button again to speak. Smartphone and tablet users should follow the same procedure.
