Tunneling Phone Line Over Internet

Does any vendor make a simple appliance that would tunnel a modem or phone
line over the Internet? I have an older box that runs a real time OS that
I cannot modify that needs to dial out by modem. I have the available
phone trunk lines at a different physical location. I would like to tunnel
the modem connections from the location with the older computer to the
location that has the phone company trunk line, tunneling by TCP over the
Internet.

There is no Windows computer at the sending or receiving end of this
application. The device I am looking for would let you take a standard
off-the-shelf analog phone and plug it in at one location and get dial tone
from the trunk at the remote location, all invisibly to the phone (e.g., no
special access codes for the outdialing device, just dial tone when going
off hook).

You could possibly try to put another computer in between with both a
serial port link and an ethernet link. The ethernet would be connected
to the Internet, of course, and you could connect its serial port to
your older computer through a null-modem cable. Your older computer
won't be gaining much speed, as it will be limited to speed of its
serial link, but who knows? You may realize some efficiencies which
could make even the modem connection seem faster.

That's a nice solution, but unfortunately the source computer in this case
uses a built in modem and presents RJ-11 to the outside world.

You should be able to put a modem on the other computer too and do a
dedicated (non-dial-up) point-to-point link between them. It's been a
while since I've used a dial-up modem, but I believe the old Hayes
commands were "ATA" for receiving, and "ATS" for sending, and that's
enough to get them to connect up without needing to dial.
