Hi. You can try to turn on logging

And check also report of impacted call on reporting server.

Good luck

Hello;

You need to check the performance counters on this server, that will help you to figure out this problem..

How do you get all the performance counters for Lync?
Get-Counter -ListSet LS:* | Select-Object CounterSetName, Description | Format-List

Here is some usage (in this case for Mediation Server Inbound Calls):
Get-Counter -Counter LS:MediationServer 01 inbound Calls(_total)- 000 Current

Want a continuous run? Add the -Continuous tag
Get-Counter -Counter LS:MediationServer 01 inbound Calls(_total)- 000 Current -Continuous

Here are some good external references:

Hopefully this helps you out!

Hi Hanafi,

issue is in host machine not in server.

Hello My friend;

what does you mean by in host machine ??

It's likely you're having a driver conflict error.  It could be Bluetooth, it could be video, webcam, or audio.  I'd see if you can eliminate the issue but setting these one by one to generic Windows drivers and watching to see if the issue goes away.  If you can determine which driver it is, then you can try different versions of it from the vendor or stick with the built-in Windows version.

Hi Hanafi,

host machine means client system(user laptop)whatever you given the answer that is for server side troubleshoot i guess i need client machine troubleshoot.i am expecting a solution here...:)

Hello Hareesh;

Then you need to enable the logging on the Lync client and open it by Snooper, on the other hand if you have a Lync monitoring rule in your environment then you can to check what is happening with this client.

Hi,

Please check the Event Viewer on the issued computer, check if there is any error message about Lync 2013.

Please rollback the Sound Card, VGA Device/Video Card, Graphic Card which Windows applied. Then restart Lync 2013 to have a test.

Best Regards
