Summary

Extend the Notifications API to allow installed PWA's to send incoming call notifications - i.e., notifications with call-styled buttons and a ringtone. This extension will help VoIP web apps to create more engaging experiences by making it easier for users to easily recognize a calling notification and answer it. Besides that, this feature will help bridge the gap between native and web implementations of apps that have them both.
