The tightwad fix is to bodge a PP3 battery onto a line

often enough to convince modems that there is a phone line. There is no
dial tone nor ring signal, so you need to turn off dial tone detection on
the calling modem ("ATX1", IIRC) and somehow tell the answering computer
to send "ATA" to answer at the right time.
Sounds like an interesting hack. But should probably be good enough for
most of what is desired.
I'm going to have to look into this.
It's just a bit of test gear, which you should be
able to find on eBay. I
suspect it will be priced like obscure test gear as well.
That's what I've found.
With the kit I have available, I'd just spin up
Asterisk or FreeSWITCH
on a handy Linux box, set up a minimal local-only PBX, and plug the
modem into a VoIP ATA. This eliminates four hops worth of latency and
jitter via an external VoIP provider and thus should reduce or eliminate
retrains and disconnects.
Yep, that's the route that I'd go too. Or maybe even FXS ports in an
adapter in the PBX itself.

I could try and order an analogue phone line, but I
suspect that KPN
doesn't have a script for that and would get very confused. (I also
don't care to pay their extortionate tariff of 11 cents per minute for
local calls.)
I'm not surprised.
I think a number of analog phone lines are now really something digital
to the neighborhood / house (possibly ~> likely VoIP) and splitting it
out the B1 locally. So even those might not support modem / fax as well
as an old school B1.
