Tyler Yust 8d2f98fb01 Fix subagent announce failover race (always emit lifecycle end + treat timeout=0 as no-timeout) (#6621)
* Fix subagent announce race and timeout handling

Bug 1: Subagent announce fires before model failover retries finish
- Problem: CLI provider emitted lifecycle error on each attempt, causing
  subagent registry to prematurely call beginSubagentCleanup() and announce
  with incorrect status before failover retries completed
- Fix: Removed lifecycle error emission from CLI provider's attempt-level
  .catch() in agent-runner-execution.ts. Errors still propagate to
  runWithModelFallback for retry, but no intermediate lifecycle events
  are emitted. Only the final outcome (after all retries) emits lifecycle
  events.

Bug 2: Hard 600s per-prompt timeout ignores runTimeoutSeconds=0
- Problem: When runTimeoutSeconds=0 (meaning 'no timeout'), the code
  returned the default 600s timeout instead of respecting the 0 setting
- Fix: Modified resolveAgentTimeoutMs() to treat 0 as 'no timeout' and
  return a very large timeout value (30 days) instead of the default.
  This avoids setTimeout issues with Infinity while effectively providing
  unlimited time for long-running tasks.

* fix: emit lifecycle:error for CLI failures (#6621) (thanks @tyler6204)

* chore: satisfy format/lint gates (#6621) (thanks @tyler6204)

* fix: restore build after upstream type changes (#6621) (thanks @tyler6204)

* test: fix createSystemPromptOverride tests to match new return type (#6621) (thanks @tyler6204)

@openclaw/voice-call

Official Voice Call plugin for OpenClaw.

Providers:

  • Twilio (Programmable Voice + Media Streams)
  • Telnyx (Call Control v2)
  • Plivo (Voice API + XML transfer + GetInput speech)
  • Mock (dev/no network)

Docs: https://docs.openclaw.ai/plugins/voice-call Plugin system: https://docs.openclaw.ai/plugin

Install (local dev)

openclaw plugins install @openclaw/voice-call

Restart the Gateway afterwards.

Option B: copy into your global extensions folder (dev)

mkdir -p ~/.openclaw/extensions
cp -R extensions/voice-call ~/.openclaw/extensions/voice-call
cd ~/.openclaw/extensions/voice-call && pnpm install

Config

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

{
  provider: "twilio", // or "telnyx" | "plivo" | "mock"
  fromNumber: "+15550001234",
  toNumber: "+15550005678",

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

  plivo: {
    authId: "MAxxxxxxxxxxxxxxxxxxxx",
    authToken: "your_token",
  },

  // 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", // or "conversation"
  },

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

Notes:

  • Twilio/Telnyx/Plivo require a publicly reachable webhook URL.
  • mock is a local dev provider (no network calls).
  • tunnel.allowNgrokFreeTierLoopbackBypass: true allows Twilio webhooks with invalid signatures only when tunnel.provider="ngrok" and serve.bind is loopback (ngrok local agent). Use for local dev only.

TTS for calls

Voice Call uses the core messages.tts configuration (OpenAI or ElevenLabs) for streaming speech on calls. You can override it under the plugin config with the same shape — overrides deep-merge with messages.tts.

{
  tts: {
    provider: "openai",
    openai: {
      voice: "alloy",
    },
  },
}

Notes:

  • Edge TTS is ignored for voice calls (telephony audio needs PCM; Edge output is unreliable).
  • Core TTS is used when Twilio media streaming is enabled; otherwise calls fall back to provider native voices.

CLI

openclaw voicecall call --to "+15555550123" --message "Hello from OpenClaw"
openclaw voicecall continue --call-id <id> --message "Any questions?"
openclaw voicecall speak --call-id <id> --message "One moment"
openclaw voicecall end --call-id <id>
openclaw voicecall status --call-id <id>
openclaw voicecall tail
openclaw voicecall expose --mode funnel

Tool

Tool name: voice_call

Actions:

  • initiate_call (message, to?, mode?)
  • continue_call (callId, message)
  • speak_to_user (callId, message)
  • end_call (callId)
  • get_status (callId)

Gateway RPC

  • voicecall.initiate (to?, message, mode?)
  • voicecall.continue (callId, message)
  • voicecall.speak (callId, message)
  • voicecall.end (callId)
  • voicecall.status (callId)

Notes

  • Uses webhook signature verification for Twilio/Telnyx/Plivo.
  • responseModel / responseSystemPrompt control AI auto-responses.
  • Media streaming requires ws and OpenAI Realtime API key.
