when calling people, there is a verification that the providers do ( ATT, TMobile, etc.) based on the SHAKEN/STIR attestation given to your outgoing calls and verification result for your incoming calls to/from PSTN. (US-only). If you want to make outbound calls, 1. get your number, and verify it with providers. 2. make sure you say its AI generated, or the fines can be serious.
