Add debug:true to watch Networking options and wire net.on('debug') to
logger.info so djs/voice internal WS/DAVE state transitions appear in
journal. Without this, the stream-watch connection went silent after
'Streaming DAVE Networking' — no ready/error/close visible. Needed to
diagnose why the WS to stream endpoint 'c-sin14-xxx:2083' produced no
events.
