I've just been through them all... I can change its properties (some have a lot of hum, some have a lot of hiss).Try playing with the "FXS Port Impedance" in the "Regional" settings. Mine is set to 600. I imagine that a mismatch here could cause that sort of thing.
The true extent of the problem is apparent through the on-hold music (I was dialling myself to test!). The noise is louder than that, so it drowns it out.
