Telephone trios let you catch your call whichever room you're in. With a main base unit and two additional handsets, you'll never have to dash to grab the phone again. Cordless functionality means you can move around while speaking, even going outside. An out-of-range indicator tells you when you've strayed too far. Handy nuisance-call block buttons mean your time won't be wasted and in-built answering machines will pick up and record messages when you're out. If you want to know who's calling, check the backlit LCD screen to see the incoming number before you answer.
