They are probably not really the same phone number as such -- rather, the
installer probably just hooked ALL the Cat5 wires up to the same block.
When
you use two lines, you don't typically wire special "line 1" and "line 2"
jack - line 1 is the inner pair and line 2 is the outer pair. So if this
house had two phone lines, then they would both be available on any jack.
Also, it's possible they used one RJ45 and one RJ11 but just wired them
all
up to the phone block - if wired "correctly" (for a phone) then the RJ45
would also work, though it was likely intended for a network.

When doing your own house I'd definitely run two CAT 5's and also two coax
lines (for TV, and also good for digital audio). Wire is cheap... you'll
be
glad it's there a couple years from now.



Waste of time and money. Everything is going wireless.
