If you truly have ethernet between the sites, then consider TDM over IP
as Chuck suggested. It will work for crap if the connection is not
PERFECT.
The only other problem is that I need multiple remote systems to dial
back to a single "server" which further complicates the matter. I
guess I can just do VoIP if I can find a provider who can support that
codec?

At least some ATA (analog telephone adapters) will allow you to
connect two of them together without a voip server in the middle.
Using g.711u as a codec will get you most of the way there - a
stable network connection with little/no packet loss and jitter
should get you the rest of the way.
Even better if you can find ATA's which do this AND use a wideband
codec (aka 128kb/s instead of 56K)
One specific thought is that obihai adapters also have a cloud
based system to connect them together. This might work for you too.
The trick will be to use a codec which passes enough data. gsm
ain't gonna cut it (except perhaps at slower speeds). g.729
probably not either, g.711u is probably your only choice, unless
you try a wideband codec.

Does such a thing exist ? I need to take two devices that use
modems to communicate and make them talk over ethernet? Like a
box that makes the modem think it has dial tone, then
establishes a virtual phone connection to another box that
rings the far device ? Does that make since ?
Can't modify the existing system/modems, just want to
eliminate the phone line and communicate over ethernet...
