Exemption rules
The Company does not claim an exemption from the STIR/SHAKEN implementation requirement. The Company owns and operates its voice network infrastructure and acknowledges its obligation to implement STIR/SHAKEN under 47 CFR § 64.6301(a). The Company has not yet completed implementation but is actively engaged in doing so, having retained a third-party implementation provider and is coordinating with its SIP trunking provider, Inteliquent (Sinch), to establish originating-level call signing. The Company's current SIP trunking arrangement with Inteliquent provides Attestation C signing at the trunk level. A detailed description of the Company's active STIR/SHAKEN implementation plan, including steps underway and estimated completion timeline, is provided in Section 3 of the accompanying Robocall Mitigation Program Description uploaded herewith.
