Someone who recently left the company ordered the following: Cisco Call Manager 7825, Cisco IPS 4240, MARS, Cisco VTC 3545, Radvision Pathfinder, Cisco 3825, and Cisco 6506. I know they had an idea of how they imagined it to work but I don't. Some of these devices do the same thing. I am trying to get an idea of how traffic would flow from outside coming in. The goal is to use VTC from client to client. Similar setup is being deployed to remote locations.
