KX-TG4321B 5.8 GHz Expandable Digital Cordless Phone With All-Digital Answering System, Night Mode, Light-Up Indicator and Call Waiting Caller ID.

Night Mode Lets You Choose Where the Phone Rings: Now you can program each handset to ring or not at your discretion. Before going to sleep, simply set the bedside handset to Night Mode so that it won't ring in your bedroom. In the meantime, the handset in the den will still ring when that important call comes in without disturbing the person who's sleeping.

See Who's Calling, Even If You're Already on the Phone: We've all become accustomed to Caller ID and its ability to let us see who's calling before we answer the phone. But what happens when you're already on the phone and another call comes in on Call Waiting? Until now, you wouldn't know who was beeping in unless you answered it. With Call Waiting Caller ID2, you get the best of both worlds. So now when you get a beep, you can see who's calling before you answer.

Put a Handset in Every Room: With one base handset included and the option of adding up to three additional handsets, all while using only one base and one phone jack, go ahead and put one in the den, the kitchen and the master bedroom so you won't have to make a run for it when the phone rings.

Never Miss a Call with the Light-Up Indicator: Don't miss important calls when the ringer is off. The Light-Up Indicator with Ringer Alert at the base of the antenna will flash quickly to show that you have an incoming call, and it will flash slowly to let you know you have a new message. So turn off the ringer and never miss a call.
