I used my friend's vtech 2.4 ghz phone, and it is the same exact thing, I also saw this at the sharper image the other day, but under that brand. Having to press the handset number is only from the base on both the ATT and vtech. When you pick up another phone, this will beep and say "parallel handset in use" or "extension in use".The range is horrible, my 900mhz DSS phones have MUCH better range.
