Prefer vm to busy signals. If I have something to say, I like to just leave a short message and I do not have to worry about trying to remember to call again. On my phone at home, we have caller ID, if it say unavailable, we do not pick up.
I have never forwarded my work phone to vm while I am at my desk. If I am there, I pick up the phone. I hardly get any call at work, we have a reception where 90% of the calls go through first, but everytime I leave my office and then return, I check the phone to see if the message waiting sign has a little arrow saying I have one. I return all received call the same day.
You guys should try call me!
