deepclaw Voice Setup
Use this skill when the user wants to call you on the phone, set up voice calling, or talk to OpenClaw via phone.
What This Sets Up
Phone calls to OpenClaw using:
- Deepgram Voice Agent API - STT, TTS, turn-taking, barge-in
- Twilio - Phone number routing
- OpenClaw - Your AI (via chat completions proxy)
Setup Process
Step 1: Clone the repo
bash
git clone https://github.com/deepgram/deepclaw.git ~/deepclaw
cd ~/deepclaw
pip install -r requirements.txt
Step 2: Get Deepgram API Key
- Go to https://console.deepgram.com/
- Sign up (free $200 credit)
- API Keys → Create API Key → Name: "deepclaw", Full Access
- Copy key immediately
Ask: "What's your Deepgram API key?"
Step 3: Get Twilio Credentials
- Go to https://www.twilio.com/ and sign up
- Copy Account SID and Auth Token from dashboard
- Phone Numbers → Buy a number with Voice (~$1/month)
Ask: "What's your Twilio phone number, Account SID, and Auth Token?"
Step 4: Get OpenClaw Gateway Token
Run this to get the token from their OpenClaw config:
bash
grep -A2 '"auth"' ~/.openclaw/openclaw.json | grep token
Or generate a new one:
If generating new, tell them to add it to
~/.openclaw/openclaw.json
under
.
Step 5: Create .env file
Create
with their values:
DEEPGRAM_API_KEY=<their_deepgram_key>
TWILIO_ACCOUNT_SID=<their_sid>
TWILIO_AUTH_TOKEN=<their_token>
OPENCLAW_GATEWAY_URL=http://127.0.0.1:18789
OPENCLAW_GATEWAY_TOKEN=<their_gateway_token>
Step 6: Ensure OpenClaw Gateway has chat completions enabled
Check their
~/.openclaw/openclaw.json
has:
json
{
"gateway": {
"http": {
"endpoints": {
"chatCompletions": {
"enabled": true
}
}
}
}
}
If not, add it and restart the gateway:
Step 7: Start ngrok
Note the HTTPS URL (e.g.,
https://abc123.ngrok-free.app
).
Step 8: Configure Twilio Webhook
- https://console.twilio.com/
- Phone Numbers → Active Numbers → Click their number
- Voice Configuration:
- A Call Comes In: Webhook
- URL:
https://<ngrok-url>/twilio/incoming
- Method: POST
- Save
Step 9: Start Server
bash
cd ~/deepclaw
python -m deepclaw.voice_agent_server
Step 10: Test
Tell them: "Call your Twilio number now!"
Watch the server logs for:
- "Connected to Deepgram Voice Agent API"
- "Agent settings applied"
- "LLM proxy request received"
Customizing Voice

Troubleshooting
When something goes wrong, check the server logs first. Here's how to diagnose common issues:
No server logs when calling
Symptom: You call, phone hangs up, but no logs appear in the server terminal.
Cause: Twilio webhook URL doesn't match your ngrok URL.
Fix:
- Check your current ngrok URL in the ngrok terminal
- Go to Twilio Console → Phone Numbers → Your Number → Voice Configuration
- Make sure the webhook URL matches exactly:
https://<your-ngrok-url>/twilio/incoming
- Save and try again
"Check your think provider settings" error
Symptom: Call connects, you hear the greeting, then Deepgram says "Check your think provider settings" and hangs up.
Cause: Deepgram can't reach the LLM proxy endpoint, or it's returning an error.
Fix:
- Test the proxy endpoint directly:
bash
curl -X POST https://<your-ngrok-url>/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{"model":"gpt-4","messages":[{"role":"user","content":"hi"}]}'
- If you get , the auth is blocking requests. This shouldn't happen with the latest code.
- If you get connection refused, the server isn't running or ngrok isn't forwarding.
- Check that OpenClaw gateway is running:
curl http://127.0.0.1:18789/health
Call works once then hangs up
Symptom: First exchange works (greeting + one response), then call drops with "FAILED_TO_THINK" in logs.
Cause: SSE stream formatting issue—usually fixed in latest code.
Fix:
- Make sure you have the latest code:
cd ~/deepclaw && git pull
- Restart the server
Words running together in speech
Symptom: TTS says "Whydo you want" instead of "Why do you want"
Cause: Markdown stripping was removing spaces between streaming chunks.
Fix:
- Update to latest code:
cd ~/deepclaw && git pull
- Restart the server
Inbound calls don't work, but everything else does
Symptom: Server responds to curl, ngrok works, but calling from your phone gets immediate disconnect with no logs.
Cause: Your carrier may be blocking calls to the Twilio number, or you're dialing wrong.
Fix:
- Verify you're dialing the exact Twilio number (with country code if needed)
- Try calling from a different phone
- Test with an outbound call from Twilio to you:
python
# Run this in Python with your .env loaded
import requests
requests.post(
f'https://api.twilio.com/2010-04-01/Accounts/{TWILIO_ACCOUNT_SID}/Calls.json',
auth=(TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN),
data={
'To': '+1YOURNUMBER',
'From': '+1TWILIONUMBER',
'Url': 'https://<your-ngrok-url>/twilio/incoming'
}
)
If this works, the issue is your carrier blocking outbound calls to Twilio.
OpenClaw returns errors
Symptom: Logs show errors from OpenClaw like "No API key found for provider"
Fix:
- Make sure OpenClaw is configured with your Anthropic API key
- Run
openclaw configure --section model
to set it up
- Restart OpenClaw gateway:
ngrok URL keeps changing
Symptom: Every time you restart ngrok, you get a new URL and have to update Twilio.
Fix: Use a fixed ngrok domain (requires ngrok account):
bash
ngrok http 8000 --domain=your-chosen-name.ngrok-free.app
Still stuck?
- Check the server logs carefully—they usually tell you what's wrong
- Test each component individually:
- Server health:
curl http://localhost:8000/health
- ngrok forwarding:
curl https://<ngrok-url>/health
- OpenClaw gateway:
curl http://127.0.0.1:18789/health
- LLM proxy:
curl -X POST https://<ngrok-url>/v1/chat/completions -H "Content-Type: application/json" -d '{"model":"gpt-4","messages":[{"role":"user","content":"test"}]}'
