Actually, something I hate is that two people in my office will see that I rang their phone some time before and they are now calling back to see what I needed. I left no message. I didn't email or IM them. I work a busy desk and usually by the time they call me I don't even remember what I called about to begin with. If I can't get one of them, I immediately move on to someone else to find an answer and once that's done I don't dwell on it. So when I get a "Hey, you called? What do you need?" an hour after the fact it's wasting my time and theirs. It's very annoying and takes my attention away from the task at hand.
I think you could end up with a learning curve--hopefully people will eventually figure out that if you didn't leave a specific message, you don't need a callback.
But you could speed that up by telling them, when they do call you back, "Oh, if I don't leave a specific message, you don't need to call me back--I move fast enough that I'll get what I need from someone else. If I don't get it, I'll call again and leave a message."
I worked at a place once that had a sort-of-unspoken culture of *leaving* a detailed message. You *never* said, "call me back"--you always said, "call me back about XYZ, and whether I can get a copy of it."
And there was once a news story about Microsoft, and the "I can't be bothered to listen to voice mail messages" culture--people would hope to save time by leaving info on the voicemail, and the Microsoft people would just delete it and call back, saying, "What did you want?" As I recall, the tone of the story was "exasperated." They Microsoft people were sort of depicted as Special Snowflakes.
I think the default business standard ought to be, "leave a message with some detail, please--enough so that I know what you want from me and can be prepared before I call you back."
Some stuff, if it's simple enough, they might not even need to call you back, but can instead set in motion whatever it was you asked for.
