Phantom Phone Call

Have you ever had someone accidentally call you on their cell phone without knowing that they called you? My boss used to do this to me all of the time on my office phone. Somehow he would accidentally dial my number (I guess on speed dial) and my voicemail would pick it up but all I could hear was background noise like the radio in his car or his conversation with players on the golf course. He didn't realize that his phone didn't hang up so I would have several minutes of this background noise. Out of curiousity I would listen for a minute or so but I never heard anything interesting or funny. How embarassing it would be to have someone hear a conversation that you didn't want others to know about! Yesterday I was listening to the radio and someone actually called the radio station by accident and you could hear what was going on in the background. It sounded like a family trying to get ready in the morning. I definitely wouldn't want that heard on the radio!
