Telnyx
Infrastructure for real-time agents
Telnyx is a licensed carrier that operates its own private global backbone, edge compute and GPUs, combining communications, AI inference and application runtime on a single control plane. It addresses the need to run real-time agents that must handle model inference, voice and messaging, and persistent state without assembling separate vendors.
Its offerings include serverless and dedicated Inference APIs with streaming and tool calling, Voice AI Agents, speech-to-text and text-to-speech, voice and messaging APIs, SIP trunking, numbers, email, fax, identity tools such as Verify and Branded Calling, networking (Cloud VPN, Global IP, IoT SIMs, eSIM), and edge primitives including Functions, Stateful Actors, KV, SQLDB, Object Storage, CloudFS and an Agent SDK. Integrations cover Salesforce, Calendly, MCP servers, webhooks, Microsoft Teams, Zoom Phone, Dialogflow, LiveKit, LangChain and the Vercel AI SDK, alongside a Telnyx CLI and MCP endpoint.
Telnyx suits developers and teams building voice agents, contact centres and connected applications. Pricing is usage-based across products, with a pay-as-you-go plan requiring no minimum spend, a committed plan offering discounted rates and higher limits for a monthly commitment, and an enterprise plan with custom contracts and rates.
