Help migrating away from NITB

Hi all, I'm starting to get used to the new stack with split components, and all seems to be working fine, SMS and USSD are working, but no voice calls yet. ps ax: 7611 pts/4 S+ 0:00 osmo-mgw -c osmo-mgw-for-bsc.cfg 7653 pts/6 S+ 0:00 osmo-bsc -c osmo-bsc.cfg 7705 pts/3 S+ 0:00 osmo-msc -c osmo-msc.cfg 7760 pts/8 S+ 0:00 osmo-mgw -c osmo-mgw-for-msc.cfg 7785 pts/0 Sl+ 1:59 osmo-trx 7803 pts/7 S+ 0:08 osmo-bts-trx -c osmo-bts.cfg 17288 pts/1 S+ 0:00 osmo-hlr -l hlr.db -c osmo-hlr.cfg 17299 pts/5 S+ 0:02 osmo-stp -c osmo-stp.cfg Config files are deeply based in the nitb.tar in the wiki. I read in an email from December that osmo-bsc_mgcp is still required. Is that the case? Thanks, Rafael Diniz
