    Why STIR/SHAKEN Matters

    The FCC requires every voice service provider in the U.S. to implement STIR/SHAKEN in the IP portions of their network or file a detailed Robocall Mitigation Plan. Providers that fail to comply risk removal from the Robocall Mitigation Database — which means downstream carriers are legally required to stop accepting their traffic.

    Combined with SipShield's real-time fraud detection, STIR/SHAKEN signing becomes more than a checkbox: it becomes an active defense that reduces spoofed traffic and keeps your ASR and NER healthy.
