So, if my telco can bill the callers for those premium calls, they surely know who they are, or at least know where they are sending the bill and getting payment from. You are mistaken, billing is very hard. Telcos show this regularly.
On the contrary: billing is easy. Getting it right is hard.
I like that Mr Thomas's answer: "Why can't we just cryptpgraphically sign the caller's ANI and use that as a method to ID real callers we care about?" since that was my suggestion to the stir folk in their very first meeting... "what about ebony phones!" said the lawyer from telco-ville.
Well to be clear, i think it's high time to just ignore the old pstn identity stuff altogether and just use the SIP From.
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!
