+# Next Session — Outbound Call UI + Remaining Work
+
+## Priority 1: Outbound Call UI
+
+**Problem:** When agent clicks Call, a toast appears and the call happens in the background. No call screen shows.
+
+**Fix:** When agent clicks Call on a lead:
+1. Immediately set `callState = 'ringing-out'` and `callerNumber` via Jotai atoms
+2. Show ActiveCallCard with "Calling {name}..." and End button
+3. Show CallPrepCard with AI summary (same as inbound)
+4. Context panel auto-loads Lead 360
+5. Sidecar calls Kookoo outbound in parallel
+6. When SIP bridge arrives (newRTCSession), auto-answer it — don't show Answer/Decline
+7. UI transitions to active call with Mute/Hold/End
+8. Call ends → Disposition form
+
+**Files to change:**
+- `src/components/call-desk/click-to-call-button.tsx` — set Jotai atoms on click, not just call API
+- `src/components/call-desk/active-call-card.tsx` — handle 'ringing-out' state
+- `src/state/sip-manager.ts` — auto-answer SIP when outbound call is pending
+- `src/pages/call-desk.tsx` — include 'ringing-out' in isInCall, set selected lead on dial
+
+**Key insight:** The call card is driven by app state, not SIP events. Set state immediately on click.
+
+## Priority 2: Remaining Polish
+- Kookoo callback creates call records (already deployed)
+- Toast for dial should be replaced with the call card (covered by Priority 1)
+- Test full outbound flow end-to-end on staging
+
+## Priority 3: Caching
+- DataProvider fires 14 queries on mount (7 × StrictMode)
+- Add deduplication or sidecar-level cache
+
+## Deploy Commands
+See memory/helix-engage-session-progress.md for full deploy instructions.
