<p>did you solve your issue?</p>
<p>I'm facing the similar issue, 4 seconds until the verto client
to have sound, in my scenario i execute action playback in FS.</p>
<p>I see the delay between DTLS handshakes:</p>

that both call legs/channels in refer call

they are sending CONTROLED stun username

<div>Thanks Mike,
<div dir="auto">all clients are
webrtc clients behind same

<div dir="auto">At the same time
video rtp/rtcp dtls is instant,
but audio is waiting for
something, my best guess is for
rtcp from client to confirm
correct ip.port or to do auto
correct.</div>
<div dir="auto">Call scenario is A
call B and B transfers(refer)
call to C.</div>
<div dir="auto">Also I see in those
5 seconds that first client, A
sends total of 6 stun username
requests and that C answers to
them all at the same time, after
5s.</div>
<div dir="auto">Can this be rtcp
problem.</div>
<div dir="auto">I was thinking to go
through video ice thread and
compare it to audio to see how
that one works instantly.</div>
