VoIP Simulator

Simulate a VoIP incoming-call notification using the Chrome 135 call-styled Notifications API. Configure caller details, request permission, fire the notification, and see the mock phone UI with Answer / Decline buttons — the same experience users get from native calling apps.

checking Notification API…

Chrome 135 extends the Notifications API with call-styled notifications for installed PWAs. Setting scenario: "incoming-call" changes the notification display to match native phone call UI — full-screen on Android, call chrome on desktop — with accept/decline actions and optional ringtone. This eliminates the need for VoIP apps to use native app shims.
