Thanks, that link is a much better overview. It seems the calls will still reach the destination network, and the phone then, but with potential for the operator to signal the likelihood of it being an unwanted or spoofed call. I imagine we will see a tickbox in the operators apps and web settings portals to block or send such calls straight to voicemail (or similar), as they'd be able to be distinguished via the reduced attestation level.
