Voice service provider None
Overall None
Exemption rules: Rule: The filer is exempt under 47 CFR § 64.6301(a), which requires STIR/SHAKEN implementation only for voice service providers that originate calls on an IP network for which they have technical control of the authentication framework. Explanation: The filer does not operate its own IP-based voice network and does not perform STIR/SHAKEN call authentication. All call origination and STIR/SHAKEN signing are performed by the filer’s upstream carrier(s). Because the filer does not control the Session Border Controllers, IP interconnections, or STIR/SHAKEN authentication equipment, it cannot implement STIR/SHAKEN directly and is therefore exempt under the above rule. The filer’s role is limited to providing retail VoIP/UCaaS services to end users through a hosted platform, and the underlying carrier fully implements STIR/SHAKEN. As required, all originated calls remain subject to a robocall mitigation program consistent with 47 CFR § 64.6305(a).
