I did stick with QMI, or at least the Qmi class. FYI, here's my patches:
Feedback is welcome.
I'm not submitting a merge request yet because the patches are on top of
an older version of Aleksander's voice-fixes branch. The newer branch
increases the version of a dependency, libqmi I believe. The newer
dependency isn't packaged in Debian so to avoid more packaging work,
I've stuck with the older branch.

Again, this is what I've done. For your interest, here is a deamon
called Hægtesse which can reliably make calls through a SIM7100 and a
PulseAudio-supported headset. It just ferries data between the TTY and
some PulseAudio streams but has to do lots of dances to keep things
From the README:
"Probably the best place for this functionality would be a PulseAudio
plugin which listens to ModemManager over D-Bus and configures itself
according to ModemManager call audio meta-data. This functionality is
still under development, however."
