the modem regime is the most problematic part of pinephone, most operations run inside the modem and the modem communicates with the phone, the AT commands is the deepest you can go before start playing with the firmware
the fundamentals of how the modem talks to the carrier should belong to the GSM protocol
since you don't get a busy message it means that the modem is not busy with another call but it tries to do something before dealing with the call, this happens to me regularly with other phones, that is I call and hear nothing and hang up and call again
if there is a new stable firmware you should see it in dmesg
if you are with an old motherboard version 1.1 maybe this causes the problem
as far as I know Manjaro Phosh works well with the calls, try it on an SD card to be sure that there is a problem
you may not be giving the AT commands with the right parameters and you leave the modem in an intermediate state
it is complicated so try phosh to be sure that everything is configured correctly and then you do your experiments
