[SR-Users] rtpengine no voice when working between DTLS-SRTP endpoints

Greetings list, I am trying to make two endpoints talking on DTLS-SRTP. But I hear on audio. Things work perfectly fine if I use RTP or SRTP with TLS. Endpoints are pjsip based application not webrtc based clients. Below are logs from rtpengine. I hope someone could point out amiss.
