#1 Retell Alternative on an Owned Network

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.

Retell vs Telnyx

Telnyx logo

Telnyx

Owns the carrier network, GPU infrastructure, and AI platform end to end. A single owned stack.

Retell logo

Retell

Orchestration layer that stitches together third-party LLM, STT, TTS, and telephony providers it doesn't own.

Simple pricing. One bill.

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.

$0.05Per minute, STT + standard TTS included
DEVELOPER EXPERIENCE

Migrate from Retell in three steps

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.

Python

from telnyx import Telnyx

client = Telnyx(api_key="YOUR_TELNYX_API_KEY")

agent = client.ai.assistants.create(
    name="support-agent",
    model="Qwen/Qwen3-235B",
    instructions="You are a helpful support agent.",
    voice="Telnyx.Natural-HD",
)
AGENT PLATFORM

Infrastructure for AI agents. Every primitive, one platform.

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.
