I just got a phone call from this number earlier today. The call ID just said "NEVADA". I don't answer calls from numbers I'm not familiar with. A woman came on the answering machine and just kept saying "hello? Hello?" This isn't the first time this has happened. I've gotten similar calls from "WASHINGTON", "PENNSYLVANIA" "LOUISIANA" and so on. Sometimes it's a woman asking "hello?" And other times it's just an automated voice saying "good-bye."
