Hello,
We already have Lync 2013 setup for IM,presence, and Conferencing.
We are willing to extend the Lync functionality to cover the firm Enterprise Voice (VoIP).
We already have Cisco IP-Phones like ( 7911,6921).
How can we protect our investment in these IP-Desk phones and let them auto-Register with the Lync2013-Enterprise Voice server role WITHOU the need for a Cisco Unified Call Manager ?
thanks,
