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.
