Add additional handsets (each handset sold separately) to your Expandable Digital Cordless DECT 6.0 Answering System. You can put one in the den, the kitchen, the master bedroom and the living room — all while using only one base and one phone jack — so you won't have to make a run for it when the phone rings. Panasonic presents the KXTGA101S with extra advanced features including big buttons for comfort, 17 hours of talk time, call waiting Caller ID1, light-up indicator with ringer/message alert, digital speakerphone and more.
