The web app includes a manifest, service worker, app icons and standalone presentation.
Evidence basis
Public PWA resources, installation interface and service-worker tests.
Deliberate boundary
iOS installation uses Safari rather than the App Store.

What can the PWA do—and where does it stop?
Does VENTEX Connect work as an installable app on iPhone, Android and desktop?
Yes. Connect is implemented as an installable PWA with standalone mode, safe-area support, controlled updates, an offline page, Web Push and device-bound subscriptions.
01
The service worker caches public app resources but not API responses or messages.
Evidence basis
Explicit cache allowlist plus offline and update checks.
Deliberate boundary
Offline mode does not expose arbitrarily stale operational history; unsent messages use a local outbox.
Web Push is device-bound and can operate without message plaintext.
Evidence basis
VAPID configuration, subscription endpoints and a default without message preview.
Deliberate boundary
iOS push requires an installed Home Screen app and explicit permission; delivery remains under OS control.
- No guaranteed background execution like a native VoIP app.
- No freely selectable push sounds for a closed iOS PWA.
- No native MDM, CallKit or continuous location integration.
- 01Test installation and push on the actual iOS/Android versions in use.
- 02Exercise an update transition during operational work.
- 03Include offline, permission and push failure in the operating procedure.

Short answers
Does VENTEX Connect work as an installable app on iPhone, Android and desktop?
No. The PWA is installed through the browser; on iOS via Safari and Add to Home Screen.
No. Web Push and sound playback remain constrained by iOS; unrestricted native background and sound control is unavailable to a PWA.
