Exemption rules
The filer does not have a STIR/SHAKEN implementation obligation because it relies on upstream voice service providers to originate, route, and sign calls using the STIR/SHAKEN authentication framework. The filer does not operate a facilities-based network, does not possess STIR/SHAKEN certificates, and does not directly sign calls. All calls originated by the filer are subject to a robocall mitigation program consistent with 47 CFR §64.6305(a), and the filer commits to responding to traceback requests within 24 hours and cooperating fully with law enforcement and industry traceback groups.
