# Stop a WebSocket audio relay

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

Stop the relay. On a standalone `ws` session this **ends the session**
(equivalent to hangup) and emits a `session.ended` webhook. On a phone
call only the relay stops and the call continues.

**Triggered webhook:** `session.ended` for a standalone `ws` session.
A deliberate stop does not emit `websocket.disconnected`; stopping a relay on
a phone call emits no stop webhook.
