Oh, *that's* what that light means!

CALLER: Yeah, I called in on Friday about a problem, and now it's Tuesday and no one's been by to help me out. I haven't received any contact about this at all and I'm very unhappy. I'm not able to do any of my work.
ME: Oookay, just give me one second, I'm going to take a look at any open issues that you might have... *reading* Soooo have you received any voicemail?
CALLER: Uh... no... I was going to check that right after this call.
ME: According to their notes, they left voicemail for you yesterday and today.
CALLER: Oh... okay. Bye.
