dtx: add detection of AMR DTX frames for osmo-bts-trx
Currently we do not detect any of the DTX frames (SID_FIRST, SID_UPDATE
etc.) Detecting and tagging those frames as is_sub is important for
measurement processing. Also the RTP marker bit must be set on each
ONSET frame.
- Add detection of DTX frames
- Tag DTX frames as is_sub and set frame type to AMR_SID
- Set RTP marker bit when ONSET frames are received
