Got a call from this number today (7/1/2017) at around 11 AM.  Caller ID had no name, just "720-259-6124".  As with all "no name" calls, I let it roll thru to voice mail.  Whoever it was didn't leave any message.  Tried calling the number back (using *67 to block my own CID).  Got a fast busy signal, which indicates that the number is either invalid or out of service.  In other words, this was a junk call.  Added the number to my phone's Call Block List.
