# Pause the relay

POST https://api.telekesher.dev/v1/sessions/{uuid}/websocket/pause
Content-Type: application/json

Temporarily pause audio in both directions while keeping the relay connected. This stops
sending the user's audio to the backend and stops playing backend audio to the session.
Pausing does not flush buffered backend audio. Works on both a per-call relay and a
standalone `ws` session.

**Triggered webhooks:** `command.websocket.pause.accepted`
