You must first set up the Actiontec Internet Phone Wizard for both Internet and normal phone calls by connecting Internet Phone Wizard to the phone jack via a phone cable. Then by default, when you pick up your phone, your phone will be ready to make landline calls. You can switch your phone to make Internet calls with a few key taps on your phone. When you receive an Internet or landline call, your phone will automatically switch to the right phone mode to handle the call.
