[VoiceOps] Confusing Spoofing Customers

We've got a customer who had something similar happen.  It turned out to be
stupidity, not anything nefarious.  A company named US Xpress had published
a bunch of their DIDs in internal documents for truck drivers to call for
daily routing instructions and pickup/drop off locations.  So they would
suddenly be flooded with drivers calling various extensions.  It took two
years to make it fully stop.  US Xpress would fix it, and then some idiot
would pull up an old file or something, and send out my customer's info a
again.

It finally fully stopped when I had our attorney craft a letter to their
CLO telling them this was the last time it would happen and not lead to
both actual and punitive damages.
