Yes it is possible. Get the one I just got, the Panasonic KTXG-9341 T. It
is not totally accessible, but it is expandable up to 6 handsets and does
have an answering machine. You can use the furnished generic greeting or
record one yourself. Most functions are spoken but not all. If you can't
find at a local store like BestBuy, you can order it direct from Panasonic
on their website:
www.panasonic.com
or by calling 1-800-7262 and following the prompts. It even has a voice
prompt when you need to recharge the handset.
