No, CNAM (Caller NAMe) data is looked up via caller ID digit 
information by the far end (or somewhere in the middle.)   This is a 
vestige of telephone companies wanting to control the entire process 
from the center, versus the "next-generation" systems like VoIP 
wanting to control it from the edges.  Welcome to the first ring of 
hell; it gets warmer the closer you get to SS7.

You cannot (yet) transmit this information to any providers in North 
America, so far as I am aware.  You would have to pay your upstream 
PSTN (SS7) carrier to insert these records in some central database, 
probably Verisign or the ILEC from which the number is purchased.  If 
you don't "own" the numbers that you're transiting, then you're out 
of luck.

An interesting trick between Asterisk servers might be to use the UUI 
(User-to-User Information) data that is part of the PRI q.931 
specifications.  It is unknown at this time how many carriers 
actually pass UUI data from end-to-end, and there currently exist 
only a few sparse patches for Asterisk that deal it.
