Got a call from this number today (8/25/2016) at around 3 PM.  Caller ID showed up as "Denver 1-720-259-1004".  When I don't recognize the number (like this one), I let it roll thru to voice mail.  The caller left no message.  I've had at least a dozen other calls in the past from Aspen Media that have rolled thru to voice mail, and where they left no message either.  However, all those previous calls showed up with a different Caller ID.  On all those previous calls, the CID showed up as "Aspen Media 1-303-786-9500".  I've already permanently blocked that 786-9500 number on my phone.  But now it looks like they're getting creative and switching off to a different CID in the 720 area code.  These idiots should get a clue.  I've just added their new phone number now to my Call Block List also.  They can try as many new CID numbers as they want.  I'll just keep blocking each and every one of them.  Hey, Aspen Media, if you ever see my posting here, I don't answer calls from numbers that aren't already in my personal address book.  Either leave a message, or (better yet), just don't bother calling.

no message left; now blocked

Tom, I got a call from 720-259-1004.  It was a survey.  Since I didn't have anything better to do at the time, I agreed to be surveyed.  I found out at about two or three questions into it that It was about bicycle riding in Denver.  It was almost comical because I am a 75 year old man who hasn't owned a bicycle since I was about 14 years old and I live about 20 miles from Denver.  I gave the lady quite a hard time and got a call waiting that I had to answer, so had terminate the survey at about 85% complete.  I wonder who has the tenacity to be a phone surveyor.

This low life POS keeps calling me, along with a ton of other robo callers. If I could I would personally beat the S out of all of them. STOP CALLING ME

This number called my in laws asking for me.  I have never lived at or with my in-laws.  Nor have I ever used their number for anything.
