Got a call tonight, June 11th 2015 at 7:20 PM from this particular phone number and my CID displayed "Maryland 301-169-3036" and there was a VM left. Amazing!!! Of course, all you heard was a lady keep on repeating "Hello.... Hello.... Hello.... Hello" and then she hung up. After looking this number up on 800 notes, it shows that it is coming from "Aspen Hill, Bethesda, Bowie" area of MD. Of course, it was a waste of their time calling me, as I don't answer my landline phone from numbers that I don't reconize, regardless who it's from and this also includes cell phone numbers too.
Of course when I typed that particular phone number into goggle search, it didn't find any matches for that particular phone number. Must be a spoof phone number
