People leave cordless phones all over the place, until they need it. I can be in the bathroom and the door bell rings, I can answer that by picking up the phone. Easy.

Here is a method I used to determine phone placement. I observed my wife and her friends as they walked in their house carrying a mobile phone. Phone rings, they answer then they walk and talk As soon as the are finished, they leave the phone there and go back to other room and finish up whatever. Over the course of the day x days in a year they have wasted many steps when a drop could go there, there and over there.

Wife now looks back and says, thanks for thinking lean and smart and anticipating my needs. Telling you, this the #1 complaint home owners have. My builder didn't listen to ME and understand my needs. Your cost to drop a cat6 line, pennies and worth the time. So what if you don't need it now...at least it is there.
