Call came in to cell phone.  Didn't answer due to caller id of Name Unknown.  Called number back and got "disconnected" message... "You have reached a non-working number of Level 3 communications."

Reverse call lookup shows it to be in the Denver, CO area.

Received a call on my cell phone.  I didn't answer due to caller id of Name Unknown.  Instead of leaving a message they left a text message.  "Please Call 743853"

Area Code lookup shows it to be in the Denver, CO area.

Computer generated message replying to a Texas One Call (before you dig) request stating that Level 3 Communications didn't have any cables buried in my yard. I already knew that!

Didn't answer call at first as I didn't recognize it. However, kept calling back so I answered. Turns out it was a response to a request I had made through Diggers Hotline letting me know there weren't any cables. Good thing I answered.

Got a call on my cell phone from someone saying they were interested in looking at something I had listed on craigslist.
