• A Strategic Initiative to Advance America's Telecommunications Infrastructure
Purpose-built infrastructure to carry high-fidelity voice, from ingress to attestation.

Zero-Hop Routing. Total Integrity.

In the world of enterprise voice, clarity is not a luxury—it's an input. Whether you're powering an AI stack, running high-volume outbound, or safeguarding critical infrastructure, the quality and route of your call define its outcome. USTelco HD Voice eliminates every traditional compromise. Our SIP-only, zero-hop routing architecture ensures calls are delivered with full audio fidelity, CLI integrity, and regulatory-grade traceability.

Proprietary SIP Stack Optimized for High-Fidelity Delivery

At the core of USTelco HD Voice is a proprietary SIP stack—engineered for:

  • Codec preservation (AMR-WB end-to-end)
  • Guaranteed CLI integrity and attestation enforcement
  • Sub-50ms call setup times (PDD reduction)
  • No transcoding, ever
  • AI-based routing decisions using real-time traffic quality metrics

This is not white-labeled SIP. This is USTelco-owned switching, hardened for clarity, speed, and lawful auditability.

 

USTelco HD Voice is not available over public SIP.
