Solid, 2-line analogue phone with 10 battery-backed-up speed-dial buttons, volume control, good sized buttons with solid feel, and speaker phone. I use them front-ended with A/D VoIP converter and get great voice sound quality. They are part of my standard VoIP package that I have installed in numerous locations. They provide years of trouble-free quality service. I am glad that over the years Panasonic has made progressive improvements on the phone instead of quit manufacturing it.
