Another option would be to use VoIP. 300 bps seems to work fine on VoIP
(1200 less so). A couple of ATAs and an account on a VoIP provider, and you
can do this. You will even be able to dial to real services in remote
places if you want. There are usually * dial codes you can use to connect
to clients on the same VoIP provider, to keep the call free.
The problem here is forcing the answering host to answer. If you have a
terminal running at the answering host, you can manually answer even an
automatic modem (and thus have the modems connected directly together), but
transferring that connection to a serial console is a little trickier.

Subject: Re: Simulated telephone
PBX Simulators, different makes and models out there
and while currently
it appears the ones on ebay cost more than it would new, they can usually
be obtained for a reasonable cost. The models I've used have a handful of
POTS jacks, 4 or 8 of them, and it gives basic tone and dial, you just
dial 1 for POTS 1, etc.
