that too was my message 12 yrs ago... I thought:
  1) cell phones and anything like a cell phone (sip things)  can 'just do this'
  2) anything not in category1 could have the data stamped by the
thing electrically connected to it (in the CO)

really, this isn't TOO hard, and it enables a new business in the
'directory of certs' business...
and clear info to the endpoints about the caller:
  "This number says 1900-foo-bart, but that's not matching the Cert I
have for FooBart services? fake-call!"

lots of good options there, little interest from 'telco lawyer troll'
in the room. #ebonyphone!
