i do tech support in a school system. so...im not really ever on the phone.
generally, if im not fixing an immediate "emergency" we have a database that the teachers enter problems into that we fix in the order recieved and then we have larger projects that are outlined and worked on by specific deadlines (for example, this summer we are switching two of the five elementary schools to OS X)
edit:
and about free time...although it is limited, becuase it is a school system, budget is strained and there are always computers/printers/etc sitting around that have been taken out of service that are labelled "broken." when i have time, i try and get those things back up and running to be used if needed.
those are mostly for my own satisfaction, though.
it pleases my boss, of course, but those machines are generally written off pretty quickly.
occasional posting, but not very much. only if im looking for answers.
