1. What's the news on using TFN as a caller ID? 1. People have been doing it for years 2. Does this require a local charge number in P-Charge-Info or P_Asserted_Identity or elsewhere? 1. It does if you want calling other toll-free numbers or 911 to work, otherwise it doesn't really matter. 3. Has the FCC or anyone else approved TFN as ANI? 1. Does anyone need to? 4. Is TF ANI supported for STIR/SHAKEN? 1. If you have the certs, you can attest to whatever you want. It's designed to create accountability for originating carriers, not police numbering formats.

It looks like Somos is pushing TFN CNAM, press release below from Mar 30, 2020. I've always understood?TF ANI to be invalid.

I agree with Paul. From what I know the 8YY ANIs are handled like any other ANI.

Are underlying carriers treating these as indeterminate, or given their own jurisdiction and rates?
