Routing telephone over ethernet cabling

[box]

I will be laying an ethernet cable into a room in my house. There is already a phone extension running into this room, but since I don't want two sets of wires, I was hoping I'd be able to use the redundant copper in a Cat5e cable to carry the phone signal as well.

I can't think of any easy way of bodging the cable to carry the phone signal. Are there adapters available out there? I'd be looking for something along the lines of RJ45 + RJ11 ---> RJ45 on both ends of the cable. ...if that makes sense...

 

[benjo plz.]

If you want your computer networked in full duplex, you won't have any redundant pairs.

I thought only two pairs inside the ethernet cable are utilised? Is this not the case?

100mbit full duplex only requires 2 pairs of the 4 pairs in ethernet cable. If you go gigabit however, that'll require all 4 pairs so as long as you stay 100mbit it should be possible.

There are adapters that will split a single RJ45 cable off into two seperate ports, so you could use one of those along with a phone to RJ45 adapter at each end.

It's not really the ideal setup, but it should work.

Thanks for the info Phemo. In that case, I think I'll just stick with two separate cables, for the sake of futureproofing.
