I got the below email from GE on this phone. I think I'll hold out to see some more reviews and for the handsets to come into play. I have 4 phones in my home and would like to swap them all over...
I do apologize sir, it completely slipped my mind. These accessory handset have not been released yet. We just released this one one month ago and we have not been given a release date for the accessory handsets.
Yup, used to work fine; now I've upgraded the firmware to 17.37 and its a paper weight. Don't bother with the details ... steer clear of this phone.
