This call is one of perhaps a dozen or more from in the last 12 days. The area codes have been, as follows, 458,845,818,603,541,786,919,484,575,205, my cell will ring twice and disconnect or ring twice when I answer and disconnect. I am at a loss as to what kind of data is being gathered but I'm sure there is a purpose to the this effort. Anyone have an idea as to what their point is?
