How Autonomous RFC 3261 SIP Voice & Valve Isolation Works

  1. Ultrasonic MNF Anomaly Detection: HydraulicAnomalyAgent detects a 01:00–04:00 SAST Minimum Night Flow spike (7.4 L/min) and pressure drop (3.85 bar).
  2. Zero-Data RFC 3261 SIP Call Placement: EcoGridVoiceCallService dials the duty engineer and vulnerable citizens via the Sputnik Devs SIP trunk (/api/v1/voice/script/22222222-2222-2222-2222-222222222201).
  3. Closed-Loop DTMF Valve Actuation: Pressing Keypad 1 posts to POST /api/v1/voice/gather/22222222-2222-2222-2222-222222222201, closing the motorized solenoid isolation valve and routing static potable water reserves to the medically vulnerable wing.
