voice-call: outbound conversation mode race — initial message falls back to Polly before media stream connects
증상
Outbound calls in conversation mode never use ElevenLabs TTS for the initial message. The message is spoken via the TwiML <Say> (Polly) fallback and then consumed, leaving the WebSocket media stream with nothing to say when it connects. Inbound calls work correctly with ElevenLabs.
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
Use --mode notify for outbound calls (one-way, uses inline TwiML). Conversation mode is broken for the initial message on outbound.
