Yes, it does need to be a true emergency if I pick up that phone at night or on weekends. I rarely make those phone calls, so he knows if I do that I am truly in need of assistance. (And generally he gets me to call my pdoc in those instances because, as T says, at that point I need my pdoc to do his "magic".) Things that aren't true emergencies I save for office hours, if needed, or I just wait until my session.
