Try looking at the Penril Alliance V.32 modems.

We use them for 9600 baud dial up to our local network.  We only
use them as Async modems, but they support Sync also.

They support V.32 at 9600 and 4800, V.22 at 2400, Bell 212A at 1200, and
Bell 103 at 0-300.

They support MNP 1 to MNP 5.

They work with both dial and leased lines (2 or 4 wire).

They can be used stand alone or in a (dumb) rack.

They support the AT command set and they have an LCD display
and buttons so all the programming can be done from the front
panel.

They support V.25 bis autodialer commands.

They also have a dialer mode called DTR dialing that might be useful to
you.  You program a phone number into the modem, and then whenever
DTR goes high, it dials the number.  (Turn your gateway on, and
the modem automatically calls.  Sounds good in theory)

The modems list for about $1,500, but we have been able to buy
them for a little over $900 in quantities of 25.  I think the
same dealers are quoting prices of about $1,100 for one.

Try calling Penril for info:

    Penril DataComm
    207 Perry Parkway
    Gaithersburg, MD 20877-2197

    (301) 921-8600

This is the same modem that Black Box sells as the All-In-One modem
for $1,295. (I assume because the picture and the specs are the same)

We've been very happy with the modem and with Penril's support.
