All I need is a volcano

A consultant upgraded our phone systems at work a few weeks ago, without telling our IT manager until afterward; since then, several of us have been having problems with our phones. My phone was the guinea pig for the tech who was trying to fix the problem. He poked at it for a while, then said that there was a newer version of the software out, and he was going to uninstall and delete my current one, and then install the new one and hope that would fix it. I said, "So you're going to sacrifice a version?"
