It's actually beyond just caching with Targus, they also allow their
customers to submit changes (read: overrides) to their database which
also contribute to the problem.

In Targus's favor, they are trying to do a good thing but as other
posters have mentioned, it's an amazingly complex system with more
carrier to carrier variation than just about any other feature out
there.  I think the cell phone providers are smart to just flat out not
implement it.

The best thing you can really do is have the person at the far end that
is seeing the wrong CNAM entry complain to their own carrier.  In my
experience people that make a provider money have better leverage than
the competitors.

99% of it comes back to:

http://www.targusinfo.com/solutions/identification/caller_name/

Syniverse uses these guys. Verisign always used its STPs and GTT to
route you to the direct CNAM databases and get you the right data from
the proper industry databases. Targus does not do that, despite their
ironically written website they're 99% of the CNAM problem in this
nation.

TNS used to use them, but recently moved to their recently acquired
Verisign network for caller ID with name data so they no longer have the
issue either.

AT&T (upper and lower case AT&T, that is) don't have this issue, nor do
the ILECs obviously.
