If you have the magic phrase to make it work, I'd like to know. I tried for about five minutes while driving yesterday, to no avail. For me, Siri is like an 80s text adventure game, except I was better at those. Edit: just now I was able to call by interacting a second time with Siri, and using the physical button. Using the button never would have occurred to me while driving.
