Exemption rules
CallSipper LLC does not implement the STIR/SHAKEN authentication framework on its network because call authentication and signing are performed by upstream voice service providers used for call termination. CallSipper operates as a hosted platform / routing provider for verified business customers and relies on upstream providers for STIR/SHAKEN where applicable. CallSipper maintains and enforces a robocall mitigation program, including customer verification, monitoring, and rapid response to traceback or enforcement inquiries.
