> After patching around broken DTLS SRTP for RTCP (ASTERISK-25642) app_echo, started after an audio prompt is played, would still not work correctly. Video would show only after a few minutes, when a new full reference frame is sent.
> This is because video frames are forwarded only after all DTLS handshakes are finished and app_echo is started. Any reference frame received earlier would be lost and the caller is not informed about it in any way.
> Chrome would send FIR requests immediately, but those would not be forwarded by app_echo. Other clients might not even send the FIR request and expect the reference frame to come on time.
> I have made a patch which fixes this behaviour in both cases.
