One stack runs the whole call. Not three vendors.
ElevenLabs gives you a great voice, then leaves you to rent the network, bolt on a carrier, and reconcile a stack of invoices. Telnyx owns it all: telephony, private global network, GPUs, and Voice AI. One provider, one bill, end to end.
14,000+ INDUSTRY-LEADING COMPANIES choose telnyx
Licensed global carrier with native SIP trunking and phone numbers built in. The call and the AI run on one owned network.
Not a carrier. You connect your own telephony provider (Twilio, Telnyx, PBX) via SIP; calls never run on ElevenLabs' own network.
A production ElevenLabs deployment means ElevenLabs plus a carrier plus often a separate LLM provider, each with its own contract and invoice. Telnyx bundles STT, standard TTS, and orchestration into one rate on one platform. Customers typically save ~45% consolidating onto the full stack.
Already running ElevenLabs over a carrier? Use the built-in import tool to bring your ElevenLabs agents directly into Telnyx, port your numbers with guided porting, and retire the extra vendors. Keep your ElevenLabs voice via BYOK if you want, now running on the Telnyx network.
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",
)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.
Telnyx bundles STT, standard TTS, and orchestration at $0.05 per minute on one bill, with LLMs and telephony priced separately on the same platform. A production ElevenLabs deployment adds a separate carrier and often a separate LLM provider, each with its own contract and invoice. Customers typically save ~45% consolidating onto Telnyx.
Yes. The Telnyx speech stack is open and swappable, with BYOK support for third-party voices including ElevenLabs. Keep the voice you love without inheriting an entire single-vendor stack around it.
No. ElevenLabs is not a carrier; you bring your own telephony provider and connect it via SIP, and the calls never run on ElevenLabs' own network. Telnyx is a licensed global carrier with native SIP trunking and numbers built in, so the call and the AI run on one owned network.
Telnyx co-locates inference and voice on its private global IP network with GPU-accelerated edge, delivering sub-200ms round trips. ElevenLabs runs on public cloud and hands transport to a separate carrier, adding hops you can't tune.
It's a swap, not a rebuild. Telnyx has a built-in import tool for ElevenLabs agents: bring them over directly, then port your numbers with guided porting and retire the separate carrier and per-component contracts. Keep your ElevenLabs voice via BYOK if you want.
Customers switching from ElevenLabs to Telnyx typically need more than text-to-speech. ElevenLabs makes voices; Telnyx runs the call. When Ultradoc, a healthcare AI platform, tried ElevenLabs alongside Twilio for their voice agents, the stitched-together architecture produced "ridiculously long response times" because audio had to travel between separate providers before reaching the caller. On Telnyx, STT, LLM inference, TTS, and call control run on one owned stack, collapsing that multi-hop latency into a single round trip. Telnyx also provides carrier-owned SIP trunking, phone numbers, and compliance (HIPAA with BAA) that a TTS provider cannot offer. Read the Ultradoc customer story.
