Query: Beware!

Description says it has "all the most popular features." Wrong! Only one handset can be used at a time--no 3-way calling! If you are on the phone with Grandma, the kids can't get on another handdset and talk with her. This is not spelled out in any of the promotional material--it is only covered on the last page of the owner's manual.
