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)
  • plivo (Voice API + XML transfer + GetInput speech)
  • 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

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" | "plivo" | "mock"
          fromNumber: "+15550001234",
          toNumber: "+15550005678",

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

          plivo: {
            authId: "MAxxxxxxxxxxxxxxxxxxxx",
            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.
  • Plivo requires 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

​
