Application share drops in the middle of the call

I started application sharing from my Library(sharer) with Lync Mac 2011(viwer) client. Call ran successfully for 4 minute and 9 seconds. Then I started getting TCP Zero Window notification from Lync end. About 25 second later Lync client sent a SIP BYE message to terminate the call with ms-client-diagnostics: 34; reason="Call terminated on a mid-call media failure where both endpoints are remote";MediaDebug="Diag:LastError:time out,time:3639413579351;LastRTP Seq:30358,SeqDelta:1,time:3639413549356;LastRTCP time:3639413546311;Last transport receive error:0x0,time:0;Last transport send error:0x0,time:0;".

In that 20-30 sencond duration no data have been transmitted from my libray to Lync client.

N.B: Usually if I don't transmit any data to Lync client after RDP Negotiation then it just shows a black screen in sharing window but doesn't terminate the call.

Hi zafarsustbd,

This was caused by a problem with the Lync for Mac 2011 client handling the TCP flow incorrectly.

Please try to install the latest version of Lync for Mac and  then test once more.
