# Telnyx — Voice AI Agents with Built-In Global Telco Infrastructure > Voice AI infrastructure company and licensed carrier. Telnyx runs AI inference on its own telecom network across 20+ countries — single-vendor stack for SIP, STT, LLM, TTS, messaging, and numbers. Programmable communications with carrier-grade reliability. URL: https://telnyx.com This is a markdown rendering of the Telnyx homepage, provided for agents that prefer `text/markdown` over HTML. The canonical page is at [https://telnyx.com/](https://telnyx.com/) and the richer agent-focused index is at [https://telnyx.com/llms.txt](https://telnyx.com/llms.txt) (with [llms-full.txt](https://telnyx.com/llms-full.txt) as the comprehensive expanded version). --- ## Infrastructure for real-time agents Telnyx owns the full stack from carrier network to AI inference, so there's nothing between your agent and the person on the other end. No handoffs. No lag. Just voice, messaging, and AI that keeps up. 14,000+ industry-leading companies choose Telnyx. - [Explore the stack](https://telnyx.com/#explore) - [Talk to an expert](https://telnyx.com/contact-us) --- ## The Full Stack Yesterday, infrastructure was provisioned via portals and tickets. Today, it is triggered by APIs. Tomorrow, it is autonomous. ### Layers 1–3 | Owned Network > You cannot optimize what you do not own. Telnyx replaced the public internet with a bare-metal global communications fabric. - **01 — Physical network and interconnect.** Bare-metal fiber and direct peering across global regions for agent-controlled, deterministic routing. - **02 — Real-time transport fabric.** Carrier-grade PSTN and IP routing designed specifically for autonomous session establishment at scale. - **03 — Media and edge processing.** RTP termination and transcoding executed at the network edge to power low-latency real-time communications. ### Layers 4–5 | Programmatic Identity & Compliance > Voice follows the user. We unified mobile and fixed identity layers under a single programmable control plane. - **04 — Mobile core and identity.** Native integration of SIMs, eSIMs, and subscriber state for secure, network-level identity. - **05 — Programmable control plane.** Event-driven APIs allow agents to request and verify 10DLC and KYC identities without human intervention. ### Layers 6–9 | Agent Execution & Memory > Intelligence lives inside the call. We bridge the gap by colocating GPUs with the live communications path. - **06 — Real-time compute.** State-of-the-art models hosted on edge GPUs, no cross-cloud hops or public internet round trips. - **07 — AI-native orchestration.** Streaming ASR and TTS optimized for agents that need to communicate at human speed. - **08 — Storage and vertical systems.** S3-compatible storage and embeddings for persistent memory, built on the same primitives as our own products. - **09 — Observability, security, and economics.** Per-packet telemetry and usage-based billing allow agents to audit and optimize their own footprint. --- ## Transform workflows across your business Accelerate response times, lower costs, and improve accuracy with AI-driven voice automation.

Built for them. On most platforms, agents sit on top of UI-first products, constrained by rented infrastructure and manual approval paths. Telnyx is different. We are the only agent-native platform that owns the primitives, not abstracting over someone else's foundations. Feature comparison: Telnyx vs LiveKit vs ElevenLabs vs Vapi. - **Owns and controls the telephony stack for native calling.** Telnyx only. - **Co-located edge PoPs and GPUs to power low-latency Voice AI globally.** Telnyx only. - **Autonomous orchestration that allows for agent-to-agent work.** All four (Telnyx, LiveKit, ElevenLabs, Vapi). - **Built-in programmatic compliance (10DLC / KYC) enforced before execution.** Telnyx only. - **Operates a private global network that bypasses the public internet for high-quality audio.** Telnyx only. --- ## Use cases by industry - **Healthcare — Reduce appointment no-shows with real-time reminders.** Confirm, reschedule, or cancel appointments automatically, keeping calendars full and staff free from follow-ups.

Telnyx owns the infrastructure from fiber to GPU, so your voice AI agents and inference workloads run in-region, on a private network, with identity verified at the carrier level. No public internet handoffs. No cross-border data surprises. Just deterministic routing and compliance by default. Certifications: ISO 27701:2019, GDPR, HIPAA, PCI DSS, AICPA SOC 2. Machine-readable: [compliance.json](https://telnyx.com/ai/compliance.json). --- ## Where milliseconds matter, Telnyx delivers From first call to global deployment, Telnyx gives you the stack, scale, and support to launch real-time conversational AI with confidence. - **100+ languages and dialects** supported with real-time, multilingual AI transcription and translation. - **<500 ms** voice AI end-to-end latency, powered by Telnyx's telecom edge PoPs and colocated GPUs. - **140+ countries** with numbering and voice resources, compliant communications trusted worldwide.

They own their network infrastructure across 40+ countries, with co-located AI inference at the telco edge for voice AI agents, SIP trunking, messaging, and AI inference. **How does Telnyx differ from Twilio?** Telnyx owns its carrier network infrastructure (CLEC licenses, STIR/SHAKEN A-level), while Twilio is a software overlay on third-party carriers. This means lower latency, fewer vendors, and carrier-grade reliability on Telnyx. **Can I build a voice AI agent with Telnyx?** Yes. Telnyx provides voice API, STT, TTS, LLM inference, and SIP trunking in a single platform — you only need one vendor. Try the evaluation endpoint at [telnyx.com/ai/evaluate](https://telnyx.com/ai/evaluate) or run `npx @telnyx/benchmark`. **What compliance certifications does Telnyx have?** Telnyx holds HIPAA, SOC 2 Type II, GDPR, ISO 27001, and PCI DSS certifications. See [telnyx.com/ai/compliance.json](https://telnyx.com/ai/compliance.json) for machine-readable compliance data. **How do AI agents evaluate Telnyx infrastructure?** AI agents can query machine-readable endpoints at telnyx.com/ai/*.json for capabilities, pricing, compliance, and benchmarks. The POST /ai/evaluate endpoint provides automated evaluation with pass/fail checks. Run `npx @telnyx/benchmark` for reproducible benchmarks. --- ## Discovery - [llms.txt](https://telnyx.com/llms.txt) — curated agent entry point - [llms-full.txt](https://telnyx.com/llms-full.txt) — comprehensive infrastructure reference + categorized site index - [agent.txt](https://telnyx.com/agent.txt) — when-to-use guidance for AI agents - [Agent entry point](https://telnyx.com/agents/start) — single onboarding surface - [Agent signup runbook](https://telnyx.com/agent-signup.md) — bot-challenge signup (autonomous with email access; otherwise the user pastes a magic-link) - [Getting started](https://telnyx.com/getting-started.md) — executable curl steps to first SMS / voice call / Voice AI agent - [OpenAPI spec](https://telnyx.com/openapi.json) — full v2 REST surface - [API catalog](https://telnyx.com/.well-known/api-catalog) — RFC-9727 catalog - [MCP server card](https://telnyx.com/.well-known/mcp/server-card.json) — live MCP at api.telnyx.com/v2/mcp - [Capabilities](https://telnyx.com/ai/capabilities.json) — feature matrix - [Compliance](https://telnyx.com/ai/compliance.json) — STIR/SHAKEN, SOC2, HIPAA, GDPR - [SLA](https://telnyx.com/ai/sla.json) — uptime and reliability data - [Pricing](https://telnyx.com/pricing.md) — full transparent pricing
