I have the following solution in place.
VCS Control Cluster Neighboured to a VCS control running B2BUA application for Lync Call and an Advanced Media Gateway.
We have a large number of Lync Calls to our video environment that are being disconnected at 4min 10sec.
The logs show that the participant ended the calls but this is not the case.
As a test we removed the AM Gateway from the solution but calls are still being disconnected at 4min 10sec.
Any ideas on this?
