bluetooth for landline

[colore]

hello

is there a wired landline phone that will work with a bluetooth headset?

or if you know a convinient way to talk to a wired landline phone without occupying your hands and that will enable you to move to another room without having to carry all the phone with you

DECT and other wireless technologies apart from bluetooth are not desired, since they produce too much radiation for 1-2 hours a day usage

thanks

anyone?
