[XS] Change in libosmocore[master]: gsm/protocol/gsm_48_103.h: add definition for TW-TS-007
by falconia 09 Dec '25

09 Dec '25

falconia has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/41633?usp=email ) Change subject: gsm/protocol/gsm_48_103.h: add definition for TW-TS-007 ...................................................................... gsm/protocol/gsm_48_103.h: add definition for TW-TS-007 TW-TS-007 is a Themyscira/Osmocom extension to AoIP interface that provides a much more compact payload format for CSD, matching the size of compressed speech payloads. Clause 9 in this spec fixes the payload type on AoIP interface for this pseudo-codec as 127, distinguishing it from CLEARMODE and from all speech codecs. Osmocom applications that may need payload type numbers for the standard set of codecs defined in TS 48.103 may also need the payload type for TW-TS-007 if they implement this extension, as this payload format is intended to "stand on equal footing" with standard AoIP payload types. Therefore, add it to the same header file.
