Imagine I have CUCM 8.5, Cisco Unity Conn 8.x and Cisco IP phones.
Question:
I am really bit confusing reading the below. Do I still need or can benefit if I install a dedicated "server" to handle Presence?
I know in the past a dedicated "server" and software was required for Presence.
Now I understand lot of Presence functionality can be handled natively by CUCM 8.5 (not sure if I need to add additional licenses for Presence though).
Then from reading the below, I could gain further functionality if I add a dedicated server for Presence. Is this right?
