LiveState loads extension states and registered devices from Asterisk on every AMI connect and follows ExtensionStatus/ContactStatus; the hub sends a snapshot then deltas batched every 250 ms (devices for admins only), pings every 30 s and closes unauthenticated sockets with 4401. The web UI keeps one reconnecting socket in a zustand store, shows a Reconnecting banner, a Dashboard (online, on a call, telephony engine) and status dots. Fix: Asterisk 24 has no 'pjsip reload'; reload with 'module reload res_pjsip.so'. AMI errors now carry the CLI output. Milestone check, automated: call-test.ts registers two baresip phones and holds a 30 s call with RTP both ways (pnpm test:asterisk); the recorded session drives the live-state tests. scripts/e2e/m2-live.mjs runs api + Asterisk + phones + browser on a private Docker network: a new extension is live in Asterisk in ~1.3 s, the dashboard shows 2/2 online and red dots during the call.
