Lync response group stops after a while with receiving incomming calls

Hi Folks, 

We have a strange issue with the response groups of Lync. 

It seems that the response group randomly stops working, what means that the users can't receive their call trough the response groups. 

Only the response group call(s) don't work, the pstn -> lync lync-> lync call just works fine. 

The quick fix is to restart one of the Lync front end servers. 
But, that is not really a solution. 

The event viewer don't show anything about this problem. Also the Lync monitoring service don't show anything.

Sometimes restarting the Windows Lync response group services solves the problem, but most of the time we need to restart the whole server. 

I'm curious some people has the same experience. 

If you need more information about our deployment, please feel free to ask.

I suggest you try to gather some logs on the Mediation server to see what is happening. Please use Lync logging tool and capture the data for S4 and then try to see if there are any errors after reporduce the problem.

Please try to enable logging tool to get detailed report:

We have recently deployed Lync 2013 and are experiencing the same issue - Response Groups stop working after a while. You phone the response group number it plays the welcome greeting, then the hold music, but never delivers the call to an agent.

The only solution seems to be to restart the Response Group Service on all of the front end servers (we have 4).

Has anyone had this problem fixed?
