Most voice AI platforms orchestrate across rented infrastructure. Telnyx is different. We spent over a decade building a carrier-grade voice network, then colocated GPUs directly with our telephony PoPs. The result: sub-200ms latency, calls that get answered, and reliability no Frankenstack can match.
We're not an orchestration layer on top of someone else's stack. We are the infrastructure.
Because we own it, you pay less. Voice AI agents at a fraction of competitor cost, production-ready in minutes.
Telnyx powers low-latency, multilingual Voice AI Agents that take action, integrate easily, and scale globally. One platform, replaces 5 vendors, providing complete flexibility and competitive pricing.
