Panasonic KX TG3021S

This model is expandable to up to three additional handsets, giving you a total of four handsets, all while using only one base and one phone jack. Go ahead and put one in the den, the kitchen, the master bedroom and the living room so you won't have to make a run for it when the phone rings.Now you can enjoy convenient, high-quality, hands-free conversations from any room in the house - not just from the phone base - with a digital duplex speakerphone on the back of the handset. So put the phone down and let Grandma and Grandpa talk to their new grandchild, or paint your nails while you chat with your best friend.By simulating a band signal above and below the normal bandwidth limitations, Voice Enhancer Technology helps clarify and improve sound reception creating a natural-sounding voice that is easy to hear and understand.Don't miss important calls when the ringer is off. The Light-Up Indicator 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, let the kids sleep, and never miss a call.
