I, too get a call every few days from this number. They always let the phone ring a couple of times, then hang-up... never going to my voicemail. I have tried to answer, but no one is there. I even tried calling back and it goes to their voicemail... but it it a Google Voice number, so it must be some scammer of some sort. (I have been thinking that its one of those companies that charge money to get details on a reverse-phone number lookup....)
