How do I learn cisco unified communications? I want to build a working system. I have (4) 2811 routers and (4) 3750s.
I can purchase cisco phones. Most of the documentation refers to "clouds" and broad level architecture. Can I install cucm on 2 servers - (1) pub and (1) sub?
Is there a physical layer drawing available for setting up a system with (7) phones, wireless, with all servers and features?
Please assist. I want to learn cisco unified communications.
