Even of the ringing signal?  That's good, as I have a couple of places
where I need a separate phone connection each side of a wall, and one run
would be preferable.

How much crosstalk would you expect on cat-5 at audio frequencies- I've not
seen any figures, and some real figures in dB would be useful for, say, a
20m run.

Presumably (though I haven't thought about this alot) lines emanating from
a home PABX might be higher impedance on the audio than from a _real_ BT
exchange, so less immune to the ring signal, which might be at a lower
impedance?  Any mileage in that theory?  (well it was the best I could come
up with at short notice)
