Make the voices stop!

So I was alone in the elevator in my office building yesterday when I heard a phone ringing. Since I was the only one in the elevator and since I had left my cell phone at home I knew it wasn't me. I thought that Hannibal Lector was hiding in the elevator shaft and his phone was blowing up. I then decided to ignore it until the phone stopped ringing and I heard "Hi, this Mindy from Consolidated Mortgage and I would really like to talk to you about your credit..." What the! My first thought was "Oh no! They've found me!" I then realized that somehow telemarketers have figured out how to call the emergency phone in our elevator. Or at least that's what I'm telling myself.
