In a recent deployment of an expressway v8.1 my client has requested I limit the incoming media ports from the internet as much as possible. They have purchased 10 traversal calls so I figure that would be 8 dynamic ports per call (pair for video, audio, content and bfcp/FECC). Thus I reduced the traversal zone to ar range of 80 UDP ports, enough to cater for a fully loaded scenario.
However, vcse keeps on throwing up errors that state there are not enough ports for the licenced number of calls. It doesn't drop complaining untill I increase the port count to around 3000 (I can't remember the exact figure). I don't understand why I would need to open such a large range of ports for a maximum of 10 traversal calls. Am I missing something obvious?
