Part of my job is evolving into me learning "all there is to know" about CUCM 7.1(3). I have only went as far as taking CCNA classes in college. What books or resources can you recommend that I utilize to learn how to manage our new IP system that was just installed. I also would like to read about more advanced topics such as configuring two separate CUCM systems to communicate over IP or some kind of trunk to make IP calls, basically.
Any suggestions are welcome. I have been looking over some CCVP books..
