I have an older relative who doesn't use a mobile and we are really struggling to get hold of her as she often doesn't hear the landline. We aren't local so do really need to be able to call her as we can't just pop in. Landline is in kitchen, she is often in living room with TV on loud and just doesn't hear it. I wondered whether there are any gadgets that could be attached to the phone and make it ring in another room? Or to make it louder? Any ideas welcome.
