it might make sense to state this in the documentation for those new flags. Right now it says "supports" which could mean Rx, Tx or both. I guess most people would assume both directions if it's not explicitly statesd. You could even rename the flag to FEAT_RX_SPEECH_* or FEAT_SPEECH_RX_* to state it is about RTP receive and not about transmit.

Hello Jenkins Builder, laforge, pespin,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/osmo-bts/+/31417
to look at the new patch set (#2).
Change subject: l1sap: Accept RFC5993 and TS 101.318 HR GSM payload
......................................................................
l1sap: Accept RFC5993 and TS 101.318 HR GSM payload
Unfotunately there are two different RTP formats for HR GSM specified
and it is unclear which should be used with GSM networks. Also esch BTS
model may have a preference for either one or the other format.
Lets set BTS feature flags to determine the preference for each BTS model
and then lets use this information to convert incoming RTP packets into
the prefered format. Doing so we will make sure that always both formats
are accepted. It also enables the BSC to make assumptions on the
preferred format so that format conversion can be carried out on the MGW
already.
Depends: libosmocore.git I05e4ed7a85f3a0451de7cd07380503a7ac76d043

PS1:
> Indeed, these can be internal BTS flags. […]
The flags were once internal flags. The approach changed. Now the BSC needs to know the preferred format to generate the SDP strings for the MGW.
osmo-bts only supports both format in the RX path, in the TX path it still transmits on the native format.
File include/osmocom/gsm/bts_features.h:
https://gerrit.osmocom.org/c/libosmocore/+/31415/comment/5c861305_eac0bed4
PS1, Line 39: BTS_FEAT_SPEECH_H_V1_RFC5993, /* Whether the BTS model supports HR GSM RTP payload in RFC 5883 format */
> in same line you say RFC 5993 and 5883. One is wrong.
Done
