I am starting application share from my application to Lync:Mac 2011 over wifi network and after some time I get the TCP Zero Window notification from Lync end. About 30 seconds later Lync Terminate the call with a BYE indicating the reason as "Call
terminated on a mid-call media failure where both endpoints are remote".
FYI: I was unable to transmit any data after the zero window notification started.
BYE Message:
