First, open the iCall program and log-on.
From the main window, dial the telephone number using the onscreen keypad. If you do not want to use the keypad, you may enter the telephone number directly into the textbox at the top of the window.
Once you have the telephone number entered, click the green telephone receiver button to place the call.
Note: calls require that you enter the appropriate country code. Therefore, U.S. numbers must be preceded by a "1" (e.g. 1-555-555-5555).
