Just an FYI that the sca.cfg needs to be updated to reflect the newer kamailio.cfg changes. Also, this script block needs to be added to the sca.cfg at the end....
#!ifdef WITH_SCA event_route[tm:local-request] { if (is_method("NOTIFY")) { record_route(); } } #!endif
Seems to not work well without it. My experience with the module.
