Last DTLS handshake packets may not be sent to the wire at all
Submitted by Daniel F
Sometimes FreeStreamer does not send last DTLS handshake packets to the wire at all, and starts sending SRTP/SRTCP. However receiver is not able to decode them, because handshake was not completed. DTLS handshake retry also fails, at least this happened during my tests.
I found this when I tested WebRTC connection between GStreamer and FreeSwitch, but this may be a generic problem (not related to WebRTC).
