Lync client failover timing question

Robert... By MSFT design, after a Lync client gets load balanced to a Lync front end, the client recieves a list of front end pool members and can (and eventually will) connect to these servers directly. Once they connect to the servers directly, BIG-IP loses the ability to manage the connection. BIG-IP has functionality designed to reconnect the client to a valid server upon the original servers failure, however when the Lync client routes around the BIG-IP, you lose the ability to take advantage of this functionality. If at this point a server goes down, it is up to the Lync client to initiate a reconnection on it's own.
