Check current calls via edge server

Question

Is there a way to check what calls are currently happening via a Lync 2013 edge server.  What I mean here is we need to take down the director pool for some maintenance and this is the next hop from the edge hence before we do this would be good to
see if there is active communications going on of any kind of modality (video, voice etc)
Thanks

Hi, 
You can use Get-CsWindowsService.
It will list you all services and activity level/sessions as below:
Status     Name            ActivityLevel
Running  REPLICA
Running  RTCSRV                Incoming Requests per Second=0,Messages In Server=0,Incoming ..
Running  RTCDATAPROXY    Server Connections Currently Active=40
Running  RTCMRAUTH         Current Requests=0
Running  RTCMEDIARELAY   Active Sessions=45
You can put edge server on drain as:
Stop-CsWindowsService -Graceful
It will not drop active session and also will not accept any new user on your edge server. Once all active sessions are completed, you can start your maintenance.
