Hi, I'm going to buy some call managers for a lab. i'd eventually like to study for the lab, but not right away. can anyone tell me which version of call manager they think I should buy?
I'm worried that if I buy 4.3 for my home lab, it will become outdated quickly due to version 6 being released.
I looked at the ccie voice lab info, and i didn't see anything that had to do with CCM version.
