Thanks Sergey.
From what I've noticed, SSLKEYLOGFILE works just for clients (chrome as
webrtc client for example), not for kamailio process itself. My kamailio
scenario, it is an sip proxy that connects an Carrier to another pbx, so no
clients like chrome are used. The tip about "mode" param in sipdump module
to generate .pcap files was an good option for that.
