I haven't had them called on me by a hotline, so it might be different, but they'll pound on your door and shout until you open it. Then they'll question you on what you were doing, come inside, and watch you get dressed, if you're not. They won't let you out of their sight for a millisecond. They'll pick up the things you were using and escort you to the ambulance nicely if you don't try anything.
