I try to return my calls but I get inundated with emails and I can't answer them all. So often, I have to refer to them my webpage and the frequently asked questions or refer them to the books. But if they take the time to call me, I try to call back. You know, I am really busy, but just happened to have an hour in the hotel room and had some time before I have to meet some people about 20 minutes.
