so you can centrally manage it all with a switch and etc.

ALSO, specify that you want to be able to handle at least 6 phone lines
from the phone company, so the house needs 6 pairs of telco wire run looped to each room..... (I would make sure they do the phones in a star configuration and not a loop through the entire house though as the star configuration provides central management as well as easier and more flexable wiring possibilities)

Thats all, of course, if you want your house to be ready for the current and the future. AND it should not cost more than like an extra 1000 bucks.
