The FCC mandates signatures to try to shift responsibility to call originators: > The FCC requires that all voice service providers certify in the Robocall Mitigation Database that they have fully implemented STIR/SHAKEN or have instituted a robocall mitigation program to ensure that they are not originating illegal robocalls. To further protect consumers, gateway providers – those serving as the entry point for foreign calls into the United States – must both implement STIR/SHAKEN and institute a robocall mitigation program. All providers are required to submit to this public database the contact information for the personnel at their company responsible for robocall-mitigation related issues. https://www.fcc.gov/call-authentication https://www.fcc.gov/call-authentication
