Pause the relay
Temporarily pause audio in both directions while keeping the relay connected. This stops sending the user’s audio to the WebSocket server and stops playing server audio to the session.
Pausing does not flush buffered server audio. Works on both a per-call relay and a
standalone ws session.
A 202 response confirms admission.
