Ribbon's STI Compliance
Ribbon STI is compliant with ATIS-1000082 and RFC8224/8225/8226. Ribbon STI implements the ATIS-82 server side specifications and can be deployed within a service provider’s network or as part of a Ribbon-hosted STIR/SHAKEN as a Service offer. In a service provider’s network, which may have many SBCs and gateways, messaging to/from Ribbon STI is centralized via the Ribbon PSX, but Ribbon STI can be invoked through any ATIS-82 API compliant client. When deployed in an originating voice service provider’s network, Ribbon’s STI solution will receive call authentication requests, provide all the steps necessary to process these requests and respond with signed assertion of caller’s identity. Following STI authentication and signing, the signature information will be passed back to the authentication request originator to be forward to the next network hop. When deployed in a terminating voice service provider’s network, Ribbon’s STI solution will receive call verification requests, provide all the steps necessary to process these requests and respond with the appropriate verification of caller’s identity. Following STI certificate verification, the verification information will be passed back to the verification request originator.
