As I understand it, if they got a document signed by their origination 
provider granting them authorization to do CNAM hosting on their own 
numbers, they could then hire someone such as Verisign to host their 
CNAM records in the so-called "PSTN database."  They'd even profit from 
this assuming they have enough subscribers.

There are probably several reasons for why they don't do this, possibly 
starting with administrative overhead and/or their provider is not 
willing to relinquish control of the records.

If someone has experience with this, feel free to correct me.  However, 
this is my understanding from my previous experience with looking up 
Caller Name information via CNAM/LIDB/SS7.
