This had no one speak then hung up on me. What I do is take the address these nusiance numbers give on here and then put it into Google street view and then I am looking at the front of the house it shows. So in under a minute I am looking at where the 'no one speaking, then hanging up' call came from. Google street view in Google maps is very handy for this. I wish someone in this day of technology could stop these nusiance/harrassment calls. Particularly when you are on the 'no calls' register.
