    Detailed Test Results

    This phone has excellent voice quality when talking and listening. We found this phone's ease of use to be good. Can conference handset to handset, as well as with an outside line.

    Phone features include a lighted keypad, which is essential if using the phone in a dark room, any-key answer, voice-mail indicator, chain dialing, helpful if you frequently use calling cards, and multilingual menus. To save energy and extend battery life, the phone automatically reduces radio power when its base is nearby. It's Energy Star compliant.

    On the downside, phone lacks auto talk and a headset jack, which is a useful feature for hands-free operation.

    About

    A 1.9 GHz DECT 6.0 multiple-handset-capable cordless phone. It can support 5 cordless handsets; 2 are included. Extra handsets with charging cradle (EL50003).
