implement audio loop-back in mobile
It would make sense for some test scenarios to have the OsmocomBB mobile simply loop back the unmodified codec frames from downlink to uplink. That way any kind of testing of the audio path could happen entirely on the core side and mobile doesn't need any support for exporting the audio in some way.

I guess this basically boils down to some vty setting that allows us to enable the loop (default: disabled).
The loop would then simply take every L1CTL_TRAFFIC_IND payload arriving from the L1 and send it back as L1CTL_TRAFFIC_REQ to the L1.
