What was the name that came up on the new/unused numbers?  Sounds like
someone populated a CNAM database with NPA-NXX-X rate-center names like

I thought that at first, but now I'm pretty sure it's not caching. 
We've assigned numbers that were in our inventory for a year or two, and

were never used, but find that the data for them is old even with the 
first call to a Cox number.  Someone could have used fake CID to 
generate a lookup and caching, but very unlikely to have happened across

so many numbers.
