I've added the ringcentral-embeddable widget to a test application. When trying to login to the widget with my test user account I get a prompt to enter a registered address for emergency calling. I can't get this to validate in the widget, through the dialog for adding an existing phone in the admin portal or from the ring central web app. I get an error stating that the address is invalid (widget) or that the service is unavailable (web app) or that the address cannot be saved (existing phone).
I also get prompted for the address when I login to the admin portal but that gives error E911 location provisioning failed .
