The new version can handle numbers that aren't in the contact list. The only thing that doesn't work now are unknown numbers (at least with Swedish settings, where they are called "Okänt nummer"), where the program displays the last number (or contact) that has called before the unknown number.

edit:
It looks like the problem is the Swedish language settings. When I tried to change to English, the program displays the standard avatar, and no number, when an unknown number is calling.
