# Self-hosted LLM protocol

## Docs

- [Self-hosted LLM protocol](https://docs.getdial.ai/api-reference/self-hosted-protocol/overview.md): The WebSocket protocol your server speaks when driving a Dial call in Self-Hosted mode — connection, signing, message types, and resumability.
- [ping_pong](https://docs.getdial.ai/api-reference/self-hosted-protocol/ping-pong.md): Keepalive between Dial and your server — Dial pings, you echo it back.
- [call_connected](https://docs.getdial.ai/api-reference/self-hosted-protocol/call-connected.md): Sent when Dial connects to your server — on every connection, including reconnects.
- [transcript_update](https://docs.getdial.ai/api-reference/self-hosted-protocol/transcript-update.md): The latest full transcript snapshot. Informational — no response expected.
- [response_required](https://docs.getdial.ai/api-reference/self-hosted-protocol/response-required.md): Dial wants the agent to speak — reply with response frames carrying this response_id.
- [reminder_required](https://docs.getdial.ai/api-reference/self-hosted-protocol/reminder-required.md): The user has been silent for a while — optionally produce a gentle nudge.
- [response](https://docs.getdial.ai/api-reference/self-hosted-protocol/response.md): The agent's spoken reply to a request — streamable, and able to end the call.
- [interrupt](https://docs.getdial.ai/api-reference/self-hosted-protocol/interrupt.md): Make the agent speak immediately, barging in out of turn.
