Landline phone that has Bluetooth

I have Plantronics and they are great except for using the phone. I am using a Plantronics Bluetooth with my cell. I’d like to use the Plantronic voyager with the landline phone as well. Does anyone have a suggestion? Sorry if this is off-topic in that it is not ha related except that ha is not very good with phones.

I had a Siemens GigaSet DECT phone with bluetooth that worked with my Siemens Pure 501’s with minitek around 2010, but making the bluetooth connection was always a bit finicky. Then I tried a Panasonic DECT phone and I couldn’t get the bluetooth to connect at all. I ended up solving the problem for myself by getting rid of the landline and just using mobile and computers for calls. I used VOIP for a while, but no longer need that with my current mobile plan…
