Got a phone call from this number today (9/14/2015) at around 3 PM Mountain Time. Caller ID was: "Out of area 1-720-692-8836". Didn't recognize the number; so I let it roll thru to voice mail. No message was left. Checked the website here, which confirmed that this is some kind of telemarketer or other scam. Added the number to my Call Block List.
Third robo today. Other two computer scams: 425-564-2613; 216-904-8194. Probably the same bunch of scammers at every one of these. I picked up and immediately hung up on first two but wasn't at home when third call came in. No VM.
