To overcome the influx of unwanted calls in the service providers network, the industry has created two new standards: STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted information using toKENs) standards. Together, these two standards, create the framework to ensure every SIP-signaled call has a certificate of authenticity attached to it — a digital signature — that allows service providers verify caller ID to mitigate unwanted robocalls and prevents bad actors from using Caller ID spoofing. With STIR/SHAKEN, service providers can restore their end customer’s trust in validity of caller ID.
Ribbon STIR/SHAKEN Solutions
Service providers can choose between two Ribbon STIR/SHAKEN solutions:
- Service provider owned and deployed within the service provider’s network
- STIR/SHAKEN as a Service (S/SaaS)
Ribbon STIR/SHAKEN Solution Deployed By Service Provider
Ribbon’s STIR/SHAKEN solution, deployed within the service provider network, includes our award winning SBC and PSX , both of which have been validated on their effectiveness of the caller authentication standards (“Secure Telephone Identity (STI) Test Plan” (TLT-2018-00010), and Authentication and Verification Services)developed by the Internet Engineering Task Force (IETF) and ATIS.
Ribbon has partnered with Neustar, a global information services provider, who provides the certificate repository, authentication and verification services, and associated management functions for STIR/SHAKEN.
In our jointly tested STIR/SHAKEN solution, the Ribbon SBC will generate and pass an identity header/signature to the authentication server via the Ribbon PSX. Neustar will perform the authentication and verification services and send back verification of the signature to the PSX, which in turn will pass that back to the SBC. The SBC has flexible handling of error conditions, e.g. “reject the call”, “continue with the call”, “continue with the call and remove Identity header” if signature verification fails.
Together, Ribbon and Neustar are leading the way with advanced solutions to protect consumers from unwanted calls and give them a greater degree of control over which calls to receive.
Ribbon STIR/SHAKEN as a Service
Select Ribbon’s S/SaaS solution to take advantage of an “all operations expense” model. With this solution, Ribbon takes care of all the Authentication and Verification functions as a managed service. The service provider’s only obligation is to have a Session Border Controller (SBC) for interworking. S/SaaS is purchased as a monthly subscription.
