Overview
STIR/SHAKEN caller ID authentication is mandatory for U.S. voice providers. DialSync signs eligible outbound traffic with A-level attestation and is listed in the FCC Robocall Mitigation Database.
Proper attestation improves answer rates, reduces carrier blocking, and demonstrates regulatory compliance to your customers and partners. Our signing infrastructure is integrated at the network level — no per-call configuration required.
Combine STIR/SHAKEN signing with our fraud protection and robocall mitigation policies for a complete U.S. compliance posture on every route.
