Not certain why but this web app list locked and doesn’t allowing typing in Google Chome. Anyway, the 78xx phones have a faulty web services on them. You can send a couple IPPS messages to them, check the web services, see its’ working, walk away for 20 minutes and then it’s dead, and requires a phone reboot to work again.
