I am inquiring in order to get feedback on some equipment and topology experiences. I need to setup a VC system where by on the networking layer I have a hub and spoke with my slowest link of 45m/b. Bandwidth isn't an issue. I have 3 sites that want to play and 3 more that are thinking about it. I need to have the all the sites to be interactive with all the other sites. Assuming that I have the proper bandwidth and that QoS is taken care of...
1. Does it matter what end units I use? Polycom, Tandberg, Cisco?
2. Is a CCM a must?
3. What components are mandotory? Do I need a Video switch/hub at the core?
