Setup

1. Create a bot with type: "inbound_call"
2. Configure Twilio credentials in Settings
3. Set your Twilio phone number webhook to:

https://api.callmissed.com/api/v1/webhooks/twilio/voice

Call Flow

Incoming call → Twilio
  → POST /api/v1/webhooks/twilio/voice
  → Returns TwiML to open WebSocket stream
  → WebSocket /ws/call/{call_id} receives audio
  → Audio chunks → Sarvam STT → text
  → Text → Sarvam LLM → response
  → Response → Sarvam TTS → audio
  → Audio streamed back to caller

WebSocket Streaming

> Coming Soon: End-to-end WebSocket audio streaming is currently a scaffold. The WebSocket endpoint exists but real-time audio processing is not yet wired.

Connect to the voice WebSocket for real-time audio:

wss://api.callmissed.com/ws/call/{call_id}

Send raw audio bytes (PCM 16-bit, 8kHz). Receive synthesized audio bytes back.

Outbound Calling (Coming Soon)

Outbound calling (type: "outbound_call") is not yet implemented. The bot type exists in the schema but the calling logic is pending. Check back for updates.
