AT&T sells a device which does just what you want (I don't have the part
number) at their Phone Center stores. Of course we charge ~16 dollars (high in
my personal "views are my own, not my company's" opinion). I have read that
GTE sells a phone with this device built in also.

This must be a common annoying occurence in many households, picking up the
phone to make a call only to hear a conversation already taking place, saying
"sorry....", and not knowing when to pick up again. A good friend of mine was
talking about making such a device many months ago ( and selling it for
millions of dollars) but never did get around to it. If you come up with a good
cheap design that works only on line power (no external battery needed) you
will have a good product. good luck.
