The trick, which I only implemented by mistake, is to have a phone number from an area where you have no business. I live in Boulder but have a number from North Dakota because I got to pick my phone number and liked the look of one. Now, if I get a call from a 303(Denver/Boulder), I'm almost sure it is real. If I get a call from 701, it is almost certainly a fake.
