Your bot handles text. We handle voice. Install the skill, verify your number, and call your Clawdbot like a phone call. It hears you speak, reads the transcript, and replies. You change nothing.
Why Voice?
Drag the slider.
Three boxes. That's the whole architecture.

Call your bot from your phone. Or tell your bot "call me" and it does. Both directions work out of the box.
POST /v1/calls { "to": "+15550123456456" }

FAQ
The stuff you're probably wondering.
Twilio gives you telephony primitives. You still need to spin up a WebSocket server, pipe raw audio to a speech-to-text service, route text to your bot, send the response to a text-to-speech service, and stream audio back. That's 3-4 services and a publicly deployed server just to say "hello." ClawdTalk skips all of that. Your bot receives text, returns text. We handle the number, the audio, the transcription, and the synthesis.
No. ClawdTalk uses a persistent outbound WebSocket connection. Your bot connects to us - we never connect to you. It works behind NAT, firewalls, VPNs, Docker networks - anywhere that can make an outbound HTTPS connection. No port forwarding, no public IP, no exposed endpoints. Your bot stays exactly where it is.
Admittedly, it can be a little slow on the free tier. This isn't because of Telnyx - our voice network is sub-100ms globally. The bottleneck is usually the agent runtime. OpenClaw (formerly Clawdbot) typically runs a thinking model not designed for real-time communication, which is why you hear a 'thinking sound' during calls while your bot processes. Pro subscribers get access to Telnyx Missions, which leverage Telnyx AI Assistant infrastructure with best-in-class latency - purpose-built for real-time voice conversations.
Your bot runs on your hardware. ClawdTalk only sees the text during a call. No training on your data. No logs stored beyond what you configure.
On the free tier, your bot can only call your verified number. This restriction exists to prevent fraud and abuse. On the Pro plan, you get a dedicated number assigned to your bot and can make outbound calls to any number. You'll need to complete a KYC (Know Your Customer) verification, and if you want to send or receive text messages, you'll need to register your number for 10DLC - we'll walk you through the entire process when you subscribe.
Free means free. No credit card. No trial that expires in 14 days. You get a real phone number and real minutes. When you need more, you pay per month.
Your ClawdBot is one phone call away.
