I didn't answer this call, and was left a voicemail message consisting of the type of music you'd hear when on hold. I actually listened to the whole thing, just in case it was a legitimate caller, but it was all just really bad, fuzzy, and tinny instrumental pop music. Someone's idea of a joke, I suppose, or maybe just a robo-dialer that plays music until someone at the other end speaks, but I blocked the number, reporting it to my wireless provider as spam. Love that option!
