More answerphone weirdness

A while ago I mentioned some weird messages left on my answerphone. This one is slightly different: a message from someone I know, but it goes all strange after about three seconds: suddenly there is all manner of screeching and wailing and perhaps even a baby crying in the background. Any idea what on earth is going on here? Content is hosted on youtube, and this time you have actual genuine pictures of the $20 piece of rubbish that I've had for the last four years serving as my main point of contact with outside world, thanks to new digital camera, which turns out to be a video/audio recorder as well -- who would have expected that?
