I have received calls from this number for over a month now (at least 5 times)and I've never known anyone with this number. Whomever is calling from this number has never left a voicemail so I'm assuming it's a person who is up to no good, but I could be wrong about that. It would be nice if they'd leave a voicemail so that I would know who they are and what they want to talk to me about.I screen all of my calls so unless they leave a voicemail they aren't going to get to talk to me at all.
