Is there a Node.js version or roadmap for WarmTransferTask?

Hey LiveKit team/community,

We’re currently building with LiveKit Agents in Node.js/TypeScript and are looking into implementing agent-assisted warm transfers for our voice agent workflow.

I noticed in the docs under Telephony → Features → Transfers → Agent-assisted transfer that the prebuilt WarmTransferTask is currently available in beta for Python, but not yet for Node.js:

Warm transfer task
Available in (BETA):
- [ ] Node.js
- [x] Python

For our use case, warm transfer is pretty important because we want the AI agent to place the caller on hold, call a human operator, provide a short contextual summary, and then connect both sides if the operator is available.

I see that the manual Node.js workflow is documented with things like:

customerSession.input.setAudioEnabled(false);
customerSession.output.setAudioEnabled(false);

Token generation with livekit-server-sdk, creating a consultation room with @livekit/rtc-node, dialing the manager with SipClient.createSIPParticipant, and then moving the participant with RoomService.moveParticipant.

That is helpful, but I was wondering:

  1. Is a Node.js/TypeScript equivalent of WarmTransferTask planned?

  2. Is there already an internal or example implementation that mirrors the Python task?

  3. For production use today, would you recommend implementing the manual workflow ourselves, or waiting for the Node.js task?

  4. Are there any known edge cases we should handle carefully in Node.js, such as manager unavailable, SIP failure, room cleanup, or re-enabling the caller audio after a failed transfer?

We’re using LiveKit for an AI voice agent in healthcare-related workflows, so a reliable warm transfer flow is a pretty important part of escalation to a human.

Would really appreciate any guidance, example code, or roadmap context here.

Thanks!

I raised this with the agent-js team. I expect they will port it over in an upcomming release.
