[M] Change in osmo-msc[master]: add voice_call_internal_mncc.msc

neels has uploaded this change for review. ( 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.
