PS1:
see my comment in the other patch (osmo-msc): Are we sure 3.1kHz Audio can mean just modem and not also voice calls?

PS1:
I would certainly agre for Fax. For 3.1kHz audio it is actually unclear what might be the payload. It could be voice or anything else.
Maybe in the GSM MS -> PLMN direction (MO calls) the MS always uses SPEECH for voice calls. But for sure if we look at the other direction (ISDN -> GSM), I would expect 3.1kHz audio and speech to be used interchangably?

Looks good and I vote for merging it. Just wanted to say that ideally we should also make the encoding of this octet configurable via the struct passed to the encoding function.

PS3:
Actually, I am not really sure if we want to guess or make assumptions in a library function doing parsing of the BCap. IMO, it's better if the intermediate structure (where we parse to) reflects what's on the wire as close as possible.
Maybe move this logic to osmo-msc.git, where we do the parsing?

Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/libosmocore/+/34746?usp=email
to look at the new patch set (#4).
The following approvals got outdated and were removed:
Verified-1 by Jenkins Builder
Change subject: gsm48_ie.c: change bearer cap structure in outgoing CSD calls
......................................................................
gsm48_ie.c: change bearer cap structure in outgoing CSD calls
Outgoing CSD calls were previously encoded with the
Bearer Capability 1 - Octet 4 "Structure" field set to
3 - Unstructured. Many Nokia, Sony Ericsson and Huawei devices
won't accept incoming CSD calls with these bits set.
Set them to 0 - Service data unit integrity for now, which
seems to work and make all tested devices happy.

gsm48_ie.c: force rate adaptation mode for CSD calls to V.110
Certain calls (seen on very old Nokias) won't have the rate adaptation flag
set on "analog" CSD calls. The field for the intermediate rate (after RA) is
still filled correctly.
Workaround this by setting the RA to V.110 whenever the RA is unset but an
intermediate rate is specified.
