Ooma does have a WiFi + bluetooth adapter.
https://www.ooma.com/telo/wireless-bluetooth-adapter/
If I'm reading the applications for this properly though, it is to add another line such as a fax to the hard wired connection. Not gonna work.
Where are you seeing "fax"?
"The Ooma Wireless + Bluetooth Adapter enables Ooma Telo to connect to the Internet wirelessly using your Wi-Fi network."
The Ooma Telo is the standard Ooma device.
Normally, it connects directly to the router.
This device apparently lets it talk to the router via WiFi.
