I saw some strange behavior in Kamailio 5.3.0 with HEPv3. My Kamailio serves webrtc and sip tls and captures that to an Homer 7.7 instance. 

I see only the UAC Parts of the message and not the answers from Kamailio in that scenario. 

Maybe I reached the max Paket size for udp. Hard to debug. In production I saw everything (but there I used and older Kamailio 5.2.x and Homer 5.5 which can handle fragment udp). 

Any ideas how to hunt the root cause of the problem? 

Cheers
