hi Soap, are we talking about internal or external clients? Lync is highly sensitive to routing issues. Are you using the same set of Lync servers and if so, are the routes configured correctly on those servers? Are the new BIG-IPs showing requests in the VIPs statistics page when the message admin tries to log in?

 

 

The Lync Logging Tool can be helpful in figuring out what's going wrong: http://technet.microsoft.com/en-us/library/gg558599(v=ocs.14).aspx

 

 

thanks

We were only testing internal connectivity, but yes, the FE's do handle traffic for external clients also once they are handed off from the edge servers. I am told that there are no configured routes on the FE servers. I also do see accepted connections on port 5061 for the FE and Director VIP's when we have tried to test.
