A:AnswerWe ordered 2 additional handsets from Best Buy when we purchased the base unit. Panasonic M/N: KX-TGA950. NOTE: You will have to register these additional handsets to your base station before they will work with your system. Refer to pp. 46-47 in the base station User's Manual for instructions on registering the handsets. We have a total of 4 handsets and they all work just fine with our base station.
