help with twilo

[young falcon]

Ive been setting up Twillo in openclaw.json but openclaw is texting me that ports are busy(ngrok)

Can someone help me with Twillo?

Yep, if you mean the Twilio voice-call plugin, the usual gotcha is using the same port as the gateway.

OpenClaw normally wants:

• Gateway on 18789
• Voice-call webhook on 3334 (plugins.entries["voice-call"].config.serve.port)
• ngrok tunneling that voice-call port, not the gateway port

So if your Twilio/ngrok config is pointing at 18789, or you set serve.port to a port already in use, you’ll get the “port busy” mess.

A sane shape is:

plugins: {
  entries: {
    "voice-call": {
      enabled: true,

      config: {
        provider: "twilio",
        fromNumber: "+1...",
        twilio: {
          accountSid: "AC...",
          authToken: "..."
        },
        serve: {
          port: 3334,
          path: "/voice/webhook"
        },
        tunnel: { provider: "ngrok" }
      }
    }
  }

}

Also, if you’re on ngrok free tier, docs say to set publicUrl to the exact ngrok URL and allowlist that host in webhookSecurity.allowedHosts.

Can you paste:

1. openclaw --version
2. the exact ngrok error
3. your redacted plugins.entries["voice-call"].config block

Docs:
https://docs.openclaw.ai/plugins/voice-call
https://docs.openclaw.ai/help/faq

If you paste the snippet, I can usually spot the bad port/config fast.

        "enabled": true,
        "config": {
    "provider": "twilio",
    "fromNumber": "+...",
    "toNumber": "+...",
    "twilio": {
      "accountSid": "...",
      "authToken": "..."
    },
    "serve": {
      "port": 3334,
      "path": "/voice/webhook"
    },
    "tunnel": { 
      "provider": "ngrok" 
    },
    "webhookSecurity": {
      "allowedHosts": ["*.ngrok-free.app"]
    },
    "outbound": {
      "defaultMode": "conversation"
    },
    "inboundPolicy": "allowlist",
    "allowFrom": ["+..."],
    "inboundGreeting": "NEXUS IS HERE"
  }
},```

Your config is close, but I do see 2 issues right away:

1. webhookSecurity.allowedHosts: ["*.ngrok-free.app"] is wrong
   That field wants the exact hostname, not a wildcard. So use something like:

"webhookSecurity": {
  "allowedHosts": ["abc123.ngrok-free.app"]
}

2. If you’re on ngrok free tier, docs say to also set the exact publicUrl:

"publicUrl": "https://abc123.ngrok-free.app/voice/webhook"

So the relevant bit should look more like:

"serve": {
  "port": 3334,
  "path": "/voice/webhook"
},
"tunnel": {
  "provider": "ngrok"
},
"publicUrl": "https://abc123.ngrok-free.app/voice/webhook",
"webhookSecurity": {
  "allowedHosts": ["abc123.ngrok-free.app"]
}

That said, 3334 itself is a valid port, so the “port busy” part usually means something on your machine is already using it, or an old OpenClaw/ngrok process is still hanging around.

Can you paste these next:

openclaw --version
openclaw status --all
openclaw logs --follow

and, if possible:

lsof -i :3334

Also, if you already started ngrok manually, don’t do both. With "tunnel": { "provider": "ngrok" }, OpenClaw will try to launch ngrok itself.
