It's gotten worse - it won't ring when suspended - the caller can't get me, call isn't registered, doesn't ring, no trace anywhere except on caller's phone.

As much as I hate to mess directly with the modem(s) - haven't had to do that since 1992 or so - it seems I finally should do that. Is there any short list of where and how to adjust settings, something like mmcli 101?

First step would be trying the FOSS modem firmware, which does quite a lot considerably better. The firmware also has possibilities to debug such issues easily. Should be possible to change the firmware with fwupd, see https://wiki.postmarketos.org/wiki/Fwupd..._.28Pro.29.
