USTelecom Proposes Robocall Mitigation Framework Addressing TDM Traffic

USTelecom proposed an FCC robocall mitigation framework (see 2002240049) incorporating voice traffic not yet covered by current mitigation strategies, such as enterprise and TDM traffic, and a way to act against voice service providers with deficient robocall mitigation programs. A newer robocall law recognizes that the secure telephone identity revisited standards and signature-based handling of asserted information using tokens "call authentication framework is a set of protocols developed for IP voice traffic," USTelecom said in filing posted Monday on docket 17-59. "Equivalent protocols for non-IP voice traffic do not presently exist. Likewise, the authentication of enterprise calls remains a subject of ongoing development work." Incompas and members Bandwidth, BT, Microsoft and TelNet met Wednesday with staff from the Consumer and Governmental Affairs Bureau, asking them to publicly identify what they consider reasonable factors for opt-out call-blocking measures. "Call blocking in a highly complex communications environment carries a high risk of unintended consequences, including the possibility that lawful traffic may be inadvertently intercepted," Incompas filed. It wants more guidance to help prevent false positives. Commissioners will vote at their March 31 meeting on mandating Stir/Shaken (see 2003090050).
