Preguntas frecuentes
Secure Telephony Identity Revisited/Secure Handling of Asserted information using toKENs (STIR/SHAKEN) is a Federal Communications Commission (FCC)-mandated, carrier-based telecom industry solution that uses digital signatures to authenticate the origin of phone calls. Its purpose is to increase trust that the information on a caller ID display is the actual originating party.
STIR/SHAKEN can help identify inbound robocalls to your contact center and interactive voice response system, and leverage automated voice authentication and self-service options. It can also help customers know who’s really calling with trusted caller ID data, so they can be confident they’re receiving legitimate calls from your company.
All carriers are required to use STIR/SHAKEN. Verizon sits on the board of the STIR/SHAKEN governance group, helping to establish policy and regulatory frameworks, to build standards and testing protocols, and to select certificate authorities. We are also investing in our network infrastructure to add capabilities to inbound and outbound calling.
