I've never had quite the aversion to voice mail that these folks do1, but still, I understand. Death to voice mail. One thing, though: I hope everyone who hates voice mail at least records an outgoing message warning callers that a callback is unlikely and providing some other way of getting in touch. It's one thing not to like voice mail, but it's quite another to have it on your phone and then just leave people hanging wondering why they never heard back from you.
1True story: I once wrote a remarkably full-featured piece of Windows software solely to keep track of voice mail at work. It started out as a project to teach myself SQL programming and sort of mushroomed from there. What a waste. But it was fun at the time.
