From comments to my earlier message, it appears that there are (at least)
>two sets of data that are being transmitted from the originating LEC. One
>is related to the caller-ID information which appears to be a rather
>fluid transition of data and not always accurate--and nor does it appear
>that it was designed to be. A second appears to be revenue associated
>data that flows through the ANI protocol. While there are legal safeguards
>in place to prevent faux-info from flowing through the caller ID function,
>it is clear that those protections are not comprehensively effective. I
>wonder if at some point, the LEC will allow the customer to select
>(presuming the technology would support such a choice) which data set a
>customer would prefer to receive for incoming calls--either the caller ID
>data, or the ANI data. Understanding that the ANI data was not designed
>for this purpose, and it would contain some flaws, it would never the less
>likely be more accurate.
