A:AnswerLooking at their website it looks like AT&T makes additional handsets. To check and see if you can get additional handsets for your model phone, I would suggest you go to their website at: www.telephones.att.com and scroll to the bottom of the page under "Accessories" click on Expansion handsets. It will show numerous handsets with model numbers they work with. Or you can call 1 (800) 222-3111 and maybe get some help there.
P.S. The model number is on the white tag under the phone base. I hope this helps you.
A:AnswerI tried two exchanges at Best Buy because there was so much like white noise on the calls. I couldn't stand it. Changed to Panasonic KX-TGF775. So far, much better and my calls have not lost connection.
A:AnswerNo, it doesn't. You can go thru the directory to find persons/businesses and then hit dial but as a true speed dial, no. I believe the base would be where speed dial might possibly be but no.
A:AnswerYes, they light up. Got extra phones from Office Depot for $ 20 each. Like phone, and can't beat price. Wish ear side of phone was a little wider. Loved Best Buy. We buy all out TV's and computers from them when they are on sale....Good luck
