Microsoft Says Nonuniform Use of Shaken Could Cause Problems

Microsoft worries how Secure Handling of Asserted Information Using Tokens (Shaken) technology will be implemented. Commissioners take up a rulemaking asking questions about giving carriers more tools to block robocalls at their June 6 meeting (see 1905150041). Microsoft representatives met with aides to all five FCC members, said a filing in docket 17-59 posted Tuesday. “We raised concerns about the possibility that voice providers may implement SHAKEN in a non-uniform manner,” the company said, giving as an example, "if the same call is treated significantly differently depending on which provider’s network is terminating the call.” Nonuniform rollout “could significantly increase the difficulty for calling service providers to build originating calling services that comply with each provider's differing approach to SHAKEN and to ensure, ultimately, that their outbound calls receive the proper designation and termination,” the company said.
