Getting to know pipewire and wireplumber a bit more, the above is actually incorrect. I still haven’t figured out why I do not have sound in calls, but at least the modem source and sink are available, listed as Analog Input and Analog Output.
I’ll paste the lot here in the hope someone sees something I’m missing, and for future reference.
