It would be interesting to know which service the callers are making
their calls through.
Is it from their US cell phone directly via their cell provider?
Is it from a landline in the US?
Because, if it is some kind of VoIP service or if these calls originate
from people living abroad or if they are currently roaming, it could be
that the CLI is simply forged by the originating carrier or somewhere
along the path and was set to some spontaneously made up value (789-0000
= 7 8 9 0 <- may be legit but since the digits are consecutive... it is
something that I would type if I had to make up a number quickly).
If it really from their cell phone or landline then I would also go with
the misconfiguration theory.
