Kamailio TLS SIP Edge Setup

I need a working SIP-edge on an Ubuntu 22 / 24 VM that lets MicroSIP register over TLS even in networks where standard SIP/VoIP traffic is blocked. The edge will terminate the TLS leg, proxy the signalling to my existing VoIP switch over plain UDP, and keep media flowing through RTP Engine...
