T10/T20: Installation Requirements

The T10 and T20 models are actual telephones and not amplifiers. Therefore, these models will replace your existing telephone rather than attach to it. These are single line analog telephones for in home/office use. Please note: these models will not be compatible with a digital phone line. Digital phone lines support multiple phone lines rather than a single line. Are all phones compatible with the amplifiers?
