I noticed that Toll Brothers now build new houses with 2 new
CAT5e lines as a standard. Why? Each CAT5e can support 4 pair
of phone lines.

It is probably easier for the builder to stock one kind of cable, and
use it, for both phone and lan pre-wires.

I noticed that both jacks on the same outlet connect to the
same phone number in my friend's new house.

Cause there is only one phone line to the house, and people expect a
phone jack to work?
