Voice command to call a POI

As a Prius owner of one month now, I'm still getting the hang of all the voice commands, but there's one that I can't seem to figure out (if it exists). Is it possible to tell the car to call a POI you found after doing a search? For example, can I ask for the nearest Italian restaurant and then after the navigation system finds it, ask the car to call the restaurant? I know I can do it through screen taps (since the phone number is stored with the address in the NAV database), so I figure I should be able to talk it through too, right?

Thanks,
Paul
