STIR/SHAKEN
STIR/SHAKEN signing and verification paths for attested calling identity on SIP networks.
STIR/SHAKEN helps authenticate calling identity in IP voice networks. We implement signing and verification paths appropriate to your role in the call chain—certificates, SIP Identity handling, and operational procedures—aligned with your carriers and the jurisdictions where you terminate traffic.
