Call Legitimacy Begins with Infrastructure

In today’s voice environment, *caller identity is not a feature—it’s a liability waiting to be mishandled.* Spoofed calls. Incomplete attestation. CLI stripping across multi-hop routes. These aren't just quality issues—they’re compliance failures that invite penalties, call blocking, and reputational harm. USTelco HD Voice ensures full regulatory trust—by embedding compliance into every SIP session, from ingress to delivery.

End-to-End STIR/SHAKEN Attestation

USTelco operates as a fully authorized STIR/SHAKEN Signing Authority. Every HD Voice call is cryptographically signed and verified at both ends of the path, with no intermediaries that break or strip headers.

Attestation A/B delivered across:

  • All U.S. domestic traffic
  • International-originating calls with verified origination
  • NNI-connected UCaaS, CCaaS, and AI platforms

Your identity stays intact—because it was never out of your control.
