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. Data Locality keeps covered data in Australian infrastructure at rest. Default STT and TTS engines run on our Sydney hardware, and inference can be pinned to Australia on request.

  • Local Australian numbers

    Telnyx holds numbers in 130+ 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, when Data Locality is set to APAC, with control over retention and deletion.

  • ACMA-licensed carrier

    Telnyx is licensed in Australia, with direct PSTN access and local numbering.

  • 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. Data Locality governs storage, and you pin inference to one region in the request.

POST /v2/ai/chat/completions

pin inference to one region, or fail

{
  "model": "moonshotai/Kimi-K2.6",
  "messages": [
    {"role": "user", "content": "Hello"}
  ],
  "region": "AUS",
  "mode": "strict"
}

// mode: strict pins inference to AUS or
// fails with a 422. It is never redirected
// to another region. Storage at rest follows
// your Data Locality setting.

What stays in Australia, and how.
