Also,
please check the kamailio-lb.log, grepping for "Outbound Register
request from b2bua"
You should see the REGISTER going out to your provider.
127.0.0.1:5080 is the standard port of the b2b2ua.
Also what is the output of
cat /etc/ngcp-config/templates/etc/ngcp-sems/etc/reg_agent.conf.customtt.tt2
