You can achive a similar effect by only allowing a narrow frequency to pass
through a filter.

I believe that telephones have cutoffs at 200 Hz and 3000 Hz, giving it 
that
distinctive sound.

I hesitate to ask...a ways off looping topic (but loops sound nice on an
answering machine?  :-)

Anyone have recommendations on a good cordless phone/answering machine
combo?  I picked up a bright silver 2.4GHz Panasonic (KX-TGss57S).    Nice,
BUT... the receiving and sending sound quality is tinny, crappy, sounding
like it's coming through a tunnel.  By comparison, my old AT&T 5450 (which 
I
bought used ten years ago) has a way better audio quality.

Any of you guys been through a similar purchase quest?

Regards,
David A.
