OUR INFRASTRUCTURE

Five vendors is a Frankenstack. One is a platform.

Every vendor boundary adds delay the caller can hear, and every dashboard shows only part of the conversation. Telnyx runs AI compute, telephony, and edge nodes in the same Sydney facility. When a call drops or a model stalls, one team owns the whole path.

WHAT'S UNDER THE HOOD?

Your Australian AI toolkit

Numbers, licenses, and teams in Australia. Your data stays in Australia at rest, in motion, and during processing.

  • Local Australian numbers

    Telnyx holds numbers in 140+ countries, with Australian numbers for voice, messaging, agents, and WhatsApp on one platform.

  • Private global network

    Voice traffic travels across our private network, reducing latency, jitter, and packet loss for consistent call quality.

  • Sydney GPU infrastructure

    AI workloads including TTS, STT, and inference run on infrastructure co-located with our telephony in Sydney, with 4,000+ GPUs available locally.

  • Australian data storage

    Call recordings, transcripts, and logs are encrypted and stored in Australian data centers, with control over retention and deletion to support Privacy Act requirements.

  • ACMA compliance

    Licensed Australian carrier. Compliant with ACMA telecommunications regulation and the Privacy Act 1988.

  • Australian support 24/7

    Work with a team in Australia for local support across your communications and AI infrastructure.

WHY TELNYX

One platform, not five vendors

  • Ultra-low latency

    Ultra-low latency

    Run models at the edge, co-located with telephony. Sub-500ms round-trip from Sydney infrastructure.

  • No vendor lock-in

    No vendor lock-in

    OpenAI-compatible endpoints work with your existing SDK. Switch models and engines without rewriting code.

  • Autoscaling by default

    Owned infrastructure

    GPUs, network, and edge compute owned by Telnyx, not rented. Every hop is ours, from the phone network to the model server.

SOVEREIGNTY

Sovereignty is a parameter, not a promise.

One company holds the license, the fiber, and the GPUs in region: the call, the model, and the data live under one jurisdiction, and you set it in the request.
