Identity

The internet never verified identity. The phone network did. Telnyx verifies, signs, and screens calls where trust is actually enforced. Authenticate calls and filter fraud at the network layer.

Carrier-grade identity is where trust starts

A voice can be cloned from three seconds of audio. Without carrier-level identity, an AI agent calling a human is indistinguishable from a scam call. The receiving carrier checks the attestation from the originating carrier, not your app. Telnyx verifies, signs, and screens at the network layer, where trust is actually enforced.

IDENTITY CAPABILITIES

Three ways to know who is on the line

At origination, during the call, and across the reputation surface.

  • A-level STIR/SHAKEN attestation

    Telnyx signs every outbound call at A-level STIR/SHAKEN, the highest trust tier in the US telephone network. Recipient carriers see a verified caller, not a suspicious one. Your calls get answered instead of flagged.

  • Deepfake and voice-fraud detection

    Deepfake detection runs natively on the voice pipeline and flags AI-generated or altered audio in under four seconds. Fast enough to interrupt a fraudulent transaction, not just log one after the fact.

  • Number verification, CNAM, and reputation

    A dashboard and API show how carriers rate your numbers in real time, so you can act before pickup rates drop. Inbound spam is filtered at the network layer. Branded Calling puts your name on the recipient's screen, not just your number.
