Before AT&T bought anywho.com, it was a great directory service.
You could look up the published info, and you could correct it.
To authenticate the correction, you had to call in from the number
being updated.

Perhaps VOIPo could use that technique? Designate a desired CID.
Then call from it (maybe enter some auth code supplied from vPanel),
and the truth in CID is fulfilled?

I suppose it could still be abused. But it would take some work to
simply foil LD charges by changing up the number on an asterisk box.

Just thinking . . .
