Or it could be a broken PBX that is simply sending invalid calling
number information (either accidentally or purposefully) and the telco
isn't blocking it.  This is not uncommon; I get calls from area code 000
and the like fairly regularly.

Or it might be someone calling from Russia or Kazakhstan, which are
country code +7.  On many occasions, I've had numbers show up as invalid
or incorrect US area codes because something doesn't handle
international numbers right.  For instance, a call from Brussels (+32 2
XXX-XX-XX) showed up as 322-XXX-XXXX, which I only noticed because I
knew that area code was reserved.
