Panasonic cordless phone KX-TGE260 base unit handset plus 4 additional handsets. All additional handsets have been registered to the base unit and work. We used this set with the base unit plugged into the phone line on the router and the extra handsets in other rooms in the house. Can also be used as an intercom to call other handsets (great feature so you don't have to yell through the house). Works great but we got rid of our landline and no longer need it. Includes instruction book. Features a built in answering machine, Bluetooth compatible, headset jack, speaker phone, flash, call wait compatible, noise reduction, handset locator plus more.
