This phone can work during household AC power loss with its base corded phone. It has very good voice quality when talking and listening. We found this phone very good to use. It has very good message quality and very good answerer ease of use. It also has a generous 24-minute message recording time and can conference handset to handset, like an intercom.
Phone features include call blocking for nuisance callers, an audio equalizer button that lets you change the treble and bass settings, a lighted keypad, which is essential if using the phone in a dark room, talking caller ID, any-key answer and voice-mail indicator. To save energy and extend battery life, the phone automatically reduces radio power when its base is nearby. It also has chain dialing (helpful if you frequently use calling cards), multilingual menus and Push-to-talk (PTT) feature. It's Energy Star compliant. Additionally, the answerer has an audible new message alert and you can record the answerer greeting using a handset.
On the downside, phone setup is overly complicated. Handset lacks auto talk and a headset jack, which is a useful feature for hands-free operation. Answerer lacks announce-only mode.
