Bluetooth?

when i am on a call and i want to switch to speaker i push the button and it gives me the following options.. iPhone .. speaker... living room. My question is how do i get this “living room “ option off? I don’t have a device with that name, its doesn't show in my Bluetooth list, i have turned off my Bluetooth, it has happened while at home and while at work i don't have any device with that name in either of those places. How can i get this option off it’s annoying when i want to switch to speaker quickly and then i can’t like i normally am. I have had this phone for about 2 years and only started happening about 2 mos ago.
