I noticed it as well when switching from 5.2.0 to 5.2.1 using the docker images, but got around it by adding a row with localhost as the destination. Kamailio did start but wasnt able to connect, which was fine.

good to know for the future implementation and super for the artifacts!


Anyone else experienced the bug regarding a empty rtpengine table causing non kamailio starting ? 

Many thanks
