I have a Unity 4.0(3) I just inherited and Im looking for a resource for patches and upgrades.
I saw there is an upgrade to 4.0(5)- not sure if I should install (4) first or just (5). any help or resources will be great.
All that being said, how does Cisco charge? can I take them to 4.2 without cost? if not whats the highest I can go.
