Hi,
I have FINALLY gotten to play with my sysmoBTS acquired many months ago, and updated to the latest packages using okpg, and am running a NITB.
great!
From the code @ https://github.com/osmocom/osmo-bts/blob/master/src/osmo-bts-sysmo/tch.c line:583 I deduct that
" #if defined(L1_HAS_EFR) && defined(USE_L1_RTP_MODE) "

The question is what "some bugs" mean. I can't tell you and it has not been a priority to figure that out. The original author doesn't remember either. :}
I'd have expected that EFR is fully supported?
the DSP fully supports it and in general it should work. We use AMR most of the time so debugging this has not been a priority.
In the osmo-nitb.cfg you can add the following for now (or do that through the vty configuration):
mncc-int default-codec tch-f fr
