This is the white and silver grandfathered hub. With my attached cordless phone I can make/receive calls and leave messages, and listen to them on the ooma app, however the hub itself doesn't work in so far as nothing happens when I press the message button. The message blinking light doesn't work I don't get a dial tone on the hub itself when I press line 1. I've powered it down and back up. Is there something else than might work like accessing it with my PC and doing something in settings?
Edit: I'm not sure how to access settings. http://setup.ooma.com doesn't work, neither does http://172.27.35.1. Nor can I get to with its internal I.P. address on my network. I have an Xfinity cable modem and an Eero 6+ router.
I recently changed my cable modem from my own Arris surfboard S33 to the Xfinity modem, so I wonder if that had anything to do with the issue. I'm thinking it's more of a hub hardware thing, since I still have my ooma phone number working through it.
Edit 2: The hub lights do blink off and on when I plug it back in while it's setting up, but then don't light up after that when pressed.
