Can I drop Twilio SMS?

Not with open source alone. You still buy segments from a carrier or a gateway. This page replaces Programmable Voice/Video. Keep a thin SMS provider if you must send texts.

LiveKit if you are embedding rooms in an app. Jitsi if people just need a meeting URL.

LiveKit / Jitsi

Realtime voice and video you host. LiveKit and Jitsi are Apache-2.0. SMS still needs a carrier — this page does not pretend otherwise.

The problem

Twilio meters voice, video, and SMS by the minute and the segment. LiveKit is Apache-2.0 WebRTC rooms. Jitsi is Apache-2.0 meetings. Neither is an SMS gateway: self-hosting SMS still requires a carrier, a SIM gateway, or a provider you pay. n8n can fan out the webhooks you already have.

Agent setup prompt

Replace Twilio realtime with LiveKit (preferred) or Jitsi.

Do not claim a self-hosted SMS replacement. SMS needs a carrier, a GSM modem, or a paid gateway.
- LiveKit: server + keys, bind HTTP/WebRTC. Jitsi if the job is a meeting room, not an SDK.
- Webhook fan-out can live on /stacks/n8n-automation. Write AGENT_PROMPT.md.
