The user can set up a telephone call in one of the following ways:

The numeric buttons in the control panel are used to enter the desired phone number or to select a phone number from different alphabetically sorted lists (e.g. missed calls, dialed phone numbers, accepted calls or own address book) by scrolling back and forth in the "Telephone" menu. If the "Accept call" button is pressed subsequently, the telephone call is established.
