I am looking for a telephone solution for my kiddo that isn’t a cell phone.
I think what I want to do may work but I need some clarification from those that know Ooma.
My router is in a coat closet that a phone just would make sense in (wireless signal is great throughout the house, no issues) so I want to set up the Ooma via Ethernet and then use a Bluetooth phone (it’s like a vintage handset phone but has no cord and only works as a bluetooth handset) for her to use as the receiver.
Is this possible? Or do I need to have one device connect to the Ooma direct and then the Bluetooth as a separate headset?
Thanks!
