Individual calling for some police benevolent association. Said he couldn't vary from his script when asked a question. Not much use in talking to me then, I replied. Not sure this wasn't a robot.
Got a call from this number today (2/16/2016) at around 3 PM. Caller ID showed "Out of area 1-720-452-0468". Let the call roll thru to voice mail. Whoever it was left no message. Added the number to my Call Block List today.
Note: I got a similar "Out of area" hang-up call like this a couple months ago (back in Dec 2015). The Caller ID on that previous call was very close to this new one. That previous Caller ID showed "Out of area 1-720-452-4808". If your Call Blocking system allows it, I would probably recommend just blocking ALL calls with that 452 prefix. That is, set your Call Block mask to "1-720-452-xxxx". I suspect that whoever is calling here is spoofing the Caller ID by simply randomly changing the last 4 digits.
