After due consideration of price, convenience, and aesthetics, I decided 
to use a modular two-line to line 1/line 2 adapter for this... the 
two-line filters ran in the US$13-US$18 range, while the modular adapter 
was US$2.50. So, now my wall jack has an adapter plug on it with two 
modular cables running to the phone with the line filter is on line 2; 
line 1 is unfiltered; and everything works as it's supposed to. Although 
it IS ugly :^(

Thanks for your input, though :^)
