Voicemail decoding assistance required

Got a call from a blocked number while I was writing the last post. I get a lot of these, but this one left a weird voicemail. Could be an issue with the digital recording or something at the beginning, but still… weird.

Any clues? Feel free to listen online or to download the MP3.

Also, if you remix it into a song, I at least want a mention in the credits. :)

Ninja Edit: On the plus side, this is another reason why I love Google Voice. It took me under a minute from getting this weirdness to posting it on the blog. Seriously, Google Voice is awesome.
