Voice Call plugin: outbound + inbound calls via Twilio/Telnyx (plugin install + config + CLI)	You want to place an outbound voice call from Clawdbot You are configuring or developing the voice-call plugin

Voice Call (plugin)

Voice calls for Clawdbot via a plugin. Supports outbound notifications and multi-turn conversations with inbound policies.

Current providers:

• twilio (Programmable Voice + Media Streams)
• telnyx (Call Control v2)
• mock (dev/no network)

Quick mental model:

• Install plugin
• Restart Gateway
• Configure under plugins.entries.voice-call.config
• Use clawdbot voicecall ... or the voice_call tool

Where it runs (local vs remote)

The Voice Call plugin runs inside the Gateway process.

If you use a remote Gateway, install/configure the plugin on the machine running the Gateway, then restart the Gateway to load it.

Install

Option A: install from npm (recommended)

clawdbot plugins install @clawdbot/voice-call

Restart the Gateway afterwards.

Option B: install from a local folder (dev, no copying)

clawdbot plugins install ./extensions/voice-call
cd ./extensions/voice-call && pnpm install

Restart the Gateway afterwards.

Config

Set config under plugins.entries.voice-call.config:

{
  plugins: {
    entries: {
      "voice-call": {
        enabled: true,
        config: {
          provider: "twilio", // or "telnyx" | "mock"
          fromNumber: "+15550001234",
          toNumber: "+15550005678",

          twilio: {
            accountSid: "ACxxxxxxxx",
            authToken: "..."
          },

          // Webhook server
          serve: {
            port: 3334,
            path: "/voice/webhook"
          },

          // Public exposure (pick one)
          // publicUrl: "https://example.ngrok.app/voice/webhook",
          // tunnel: { provider: "ngrok" },
          // tailscale: { mode: "funnel", path: "/voice/webhook" }

          outbound: {
            defaultMode: "notify" // notify | conversation
          },

          streaming: {
            enabled: true,
            streamPath: "/voice/stream"
          }
        }
      }
    }
  }
}

Notes:

• Twilio/Telnyx require a publicly reachable webhook URL.
• mock is a local dev provider (no network calls).
• skipSignatureVerification is for local testing only.

Inbound calls

Inbound policy defaults to disabled. To enable inbound calls, set:

{
  inboundPolicy: "allowlist",
  allowFrom: ["+15550001234"],
  inboundGreeting: "Hello! How can I help?"
}

Auto-responses use the agent system. Tune with:

• responseModel
• responseSystemPrompt
• responseTimeoutMs
