There you go, sipexer test passed, which means all good on the MS side. Alice/Bob uri username doesn't change anything here, ignore it.

Another idea: do you have force_rport anywhere in the Kamailio script? Would be helpful to see the full script as well.

The global account is the development test account with the Teams license without calling. But with this license you will be able to test the Teams trunking.

here you go for the sipexer test below and it's successful but in the sngrep I see the options packet for alice without this command on udp when executing the default command for sipexer.
