This is just part of the problem.  Another part of the problem is that the price
of a 2400 bps modem has dropped so much due to competition, that the modem
guts themselves are sacrificed.  Another problem is that 2400 bps modems are
noisier than the 1200 bps modems because the Rx and Tx bands are much closer
together.  That doesn't mean that you can't build a modem that isn't noisy
just that it is more expensive.  I would recommend the AT&T 4024CEO modem.
It has a very good modem circuit, MNP and a fairly good price to boot.  Other
modems that I have heard of that are good (but I know nothing about) is
the Practical Peripherals modems.  (This is heresay and I don't think that they
have MNP yet).
