[Freeswitch-users] Quality ANALOG Speaker Phone

Hi All, Can anyone suggest a true quality analog line speaker phone? My mother has severe hearing loss and cannot use a handset to talk at all. She does "ok" with speaker phone, but her's is terrible quality. All my searches keep up with digital (VOIP) or USB speakerphones. Why not digital, you say? Because they are OLD and stubborn, and of course their house is wired for analog phones! Sean
