The "CO emulator" sold by Black Box will do this, for limited numbers
of connections. The model I have is smaller than a phone book and
supports 4 phones. The lingering question I have (since I haven't
powered it up in 10+ years) is if it supports two simulaneous
connections, or only allows one of three extensions to call the
primary. In any case, for at least a single connection, it allows two
modems to talk, each thinking they are attached to the POTS network -
dial tone, ring tones, ring voltage, the whole enchilada.
Of course, if you want to support more than one or two lines, a small
PBX is the way to go.
My old COMBOX product would only be useful for point-to-point. It's
as real a connection as a PBX, but only two lines. In practice, that
should be enough, unless you really want to sit people down in front
of a machine and have them pretend they are a BBS user and make them
choose from two or three different destinations. Entertaining, but
Of course, you'll have to simulate busy signals as well ;-) [ except
when Star Trek is on TV - that was always the best time to call the
local BBSes - all the nerds were in front of their televisions, and
they didn't have their computers in the same room back then ]
