This phone can work during household AC power loss with its base corded phone. Excellent voice quality when talking, very good when listening. Very good ease of use for both phone and answerer. It has very good message quality. Can conference handset to handset (no need to yell from room to room) or with an outside line.
Other features include a lighted keypad (which is essential if using the phone in a dark room), talking caller ID, any-key answer, voice-mail indicator, chain dialing (helpful if you frequently use calling cards), and multilingual menus. It also has a push-to-talk (PTT) feature as well as audio equalization settings. It's Energy Star compliant. Additionally, the answerer has an audible new message alert and you can record answerer greeting using handset.
On the downside, it has a rather brief 12-minute message recording time, and it lacks useful features such as auto talk and a headset jack (great for hands-free operation). Additionally, the answerer lacks announce-only mode.
