[VoiceOps] IAM callername instead of CNAM

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
"BOSTON MA", or "CELL - MONTRE CA".

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.
