When calls break on a stitched stack, no one owns the fix.
Retell wires together someone else's LLM, speech engine, and Twilio telephony: multiple vendors, multiple bills, and finger-pointing when calls fail. Telnyx owns the network, the GPUs, and the AI platform end to end. One provider, one bill.
14,000+ INDUSTRY-LEADING COMPANIES choose telnyx
Owns the carrier network, GPU infrastructure, and AI platform end to end. A single owned stack.
Orchestration layer that stitches together third-party LLM, STT, TTS, and telephony providers it doesn't own.
A Retell deployment bills per component: voice engine, LLM, TTS, Twilio telephony, and per-number fees, each from a different vendor. Telnyx bundles STT, standard TTS, and orchestration into one rate on one contract. Customers typically save ~45% consolidating onto the full-stack platform.
Low lift. Use the built-in import tool to bring your Retell agents directly into Telnyx: system prompts, tools, and flow logic carry over automatically. Port your numbers, point traffic at one owned stack, and drop the Twilio middle layer entirely.
From carrier network to co-located GPU compute, Telnyx owns every layer your agents need to run voice AI and inference in real time. No Frankenstack. No rented infrastructure. One control plane for inference, voice AI, and global communications. Configure once, deploy globally.
