Got a call from this number today (11/5/2015) at around 7 PM Mountain Time. Caller ID showed "ALLIANCE FOR SU 1-303-405-6708". Anytime I don't recognize the number, I always let it roll thru to voice mail, which is what I did again this time. They left no message. I checked the 800notes website here; and confirmed that this was nobody that I wanted to talk to. Added their number to my Call Block List.
