It sure sounds like it. TWTC is "cheating", I suppose, and depriving the rightful owner of that number of their CNAM revenue (should you take the carrier view of things).
Regardless of what the "best" answer is, in the US all carriers are supposed to deliver CNAM by dipping the central database, paying the owning carrier, and delivering the result to their subscriber. But that's really a discussion for another thread.
Another "cheater" that has a very annoying policy... Cox Communications seems to have a 6-18 month lag in their CNAM update policy. I really don't know how they do it (download and store all CNAM?), but all CNAM changes take a very long time to reach their customers. It's a source of constant complaints when our customers (businesses) call their homes (Cox) and get an old CNAM.
Usually this is because they're using data from TargusInfo that is woefully outdated, based on Directory data, or a number of other issues. Syniverse and TNS use this data for their SS7 based CNAM products (as well as their IP based ones, if I recall). Thus those who use those providers will often see such discrepancies. Very frustrating. -Paul
