Same report as above. We receive annoying, hang-up calls from this number at odd hours of the day or night - such as AFTER 10 PM. Since the number comes from the Denver-Boulder-Lakewood area in Colorado, we are guessing that, while it COULD just be a prank call - or an attempt to hack into our phone system - it could ALSO be part of some political campaign - since there are a lot of Colorado politicians who have headquarters offices in that area. But, it seems odd that IF this is someone making calls regarding some political candidate or other - that they would NOT have a voice mail system set up to give their campaign spiel in the event that someone calls back to find out what the caller wanted. At any rate, the odd hours are VERY annoying and IF I find out that there IS some sort of political campaign behind the calls, I will be sure that I do NOT vote for whomever is making these calls!
Unwanted call on 10/25/14 from this number. When I answered there was no one there. When I called back I got a message saying this number was not accepting calls at this time.
