Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/libosmocore/+/33911
to look at the new patch set (#3).
Change subject: gsm_08_08: define GSM0808_SCT_EXT (separately)
......................................................................
gsm_08_08: define GSM0808_SCT_EXT (separately)
As per 3GPP TS 48.008, section 3.2.2.103, the "Codec Type" field may
contain either a certain 3GPP Speech Codec Type directly (4 bit value),
or the so called "Codec Extension" = 0xFh, in which case the real Codec
Type follows in the next octet as "Extended Codec Type".
CSD is such an example, the encoding is defined as follows:
8 7 6 5 4 3 2 1
+----+----+----+----+-------------------+
| -- | PI | PT | -- | 0xFh |
+----+----+----+----+-------------------+
| Extended Codec Type (CSData) |
+----+----+-----------------------------+
| R2 | R3 | |
+----+----+-----------------------------+
CSData is coded with 0xFDh or '1111 1101' (0xfd).
Let's have the "Codec Extension" value clearly defined in the header
file, but intentionally separate from the other GSM0808_SCT_* values.
