Yes, either they will work with Targus, Versign, etc who do commercial 
CNAM hosting, or they work with their CLEC partner who would presumably 
already have such an agreement in place.

It's my understanding that with an LOA from your CLEC or ILEC (kind of 
the opposite of the LOA you need to port a number), you can have your 
own CNAM records hosting with one of the companies listed above and make 
money.  We're talking a fraction of a cent per call so unless you have 
many DIDs and many more calls, it's not usually worthwhile.

Most smaller ITSPs either don't know how this or don't have the volume 
to make it feasible. 

In Canada, we just include the name in the SS7 signaling on a per-call 
basis and bypass this whole mess :)
