Initially all your contacts will be assigned to the line you chose as your default voice line during set up. If you want to change this, there is an indicator within each contact that gives you the option to change which line you use for that contact.

If you're just entering a phone number straight into the dialler, you'll be able to select which line you call that number from in the options on screen.

For incoming calls, there is an indicator to show which line you're receiving the call on. The indicator is the first letter of the name you assigned to each line - for example, if your labels are called Personal and Business, the call indicator would be a P or a B.
