Description

I've applied https://gerrit.osmocom.org/#/c/4980 to current osmo-msc master and Using a TTCN-3 testcase for MO call to MNCC I'm getting the attached protocol trace.

First everything looks great:
  • CRCX for RAN side is performed + ACKed
  • CRCX for CN side is performed + ACKed
  • AoIP Assignment Request is sent (with correct IP/Port)
  • AoIP Assignment Complete is received (with correct IP/Port)

I would expect that the IP/Port from the AoIP Assignment Complete would then immediately result in a MGCP MDCX on the RAN side connection.

For some reason it isn't happening. Any ideas?
