A:AnswerNo you need the ds6250 handset. If you look at the box your ds6251-2 came in it says it needs the ds6250 to expand. As far as I can find it is the only one that works with your system. Very frustrating since Best Buy doesn’t sell it. I had to order it thru the manufacturer and return these ones.
