I think like everyone is kind of saying here, the key is an introduction/intermediary to get your foot in the door. Even if it's just a friend of a friend. Otherwise, you can always try to e-mail out of the blue but calling is probably a little bit too aggressive. The worst thing that could happen is that someone doesn't reply to your e-mail. Also, I'd be prepared for this meeting to be not just about you getting a job. Come with a lot of interesting questions to ask the person and make it about them and their company. When they ask about you, casually drop that you're looking for a new gig but don't make a big deal about it at all.
