laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-msc/+/31747 ) Change subject: add voice_call_internal_mncc.msc ...................................................................... add voice_call_internal_mncc.msc Same as voice_call_external_mncc.msc, but run with internal MNCC. Shows some curious differences like the MNCC_LCHAN_MODIFY that internal MNCC sends, but external doesn't.

[M] Change in osmo-msc[master]: tweak MNCC logging, add RTP info
by laforge 09 Mar '23

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-msc/+/31743 ) Change subject: tweak MNCC logging, add RTP info ...................................................................... tweak MNCC logging, add RTP info Omit "in state FOO", because LOG_TRANS() already logs the state. Most MNCC "rx" logging was duplicated. Log "rx" only once. If there is RTP information passed with the MNCC message, log it: - if there is SDP, log the SDP information. - if there is no SDP, log the legacy MNCC RTP fields, if any. One motivation to do this is to get RTP information in ladder diagrams generated by msc_log_to_ladder.py without the need to add udtrace MNCC logging to osmo-msc; and also to get RTP info for internal MNCC, where udtrace doesn't apply, because no unix domain socket is involved in internal MNCC operation.
