This number came up on my cell - they didn't leave a message. I called the number back a few minutes later but no one answered. A few minutes later the police showed up at my door and said they got a 911 call from my phone.
Got a call just a few minutes ago, didn't recognize the number. Looked it up on here -- I'm glad I did before I called the number back. Looks like it's some sort of routing to 911, don't do it.
