We have a unique issue: Two company intranet sites A& B are connected with 300Mbps, Lync Server (2015) is at Site A.
When we make the Lync client full screen the video on Site B freezes completely and then starts and keep freezing randomly. It works fine if we do not make it full screen. Site A client works fine on full screen.
We do not see the issue if the calls are made within the sites.
The two sites are connected via 300 Mbps Internet Link. Any suggestions??
