[VoiceOps] Outbound Caller-ID Name Issue on Certain Carriers

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.
