RADVISION | RADVISION Port Security Reference Guide
Note:
As mentioned above, if there is a firewall between the H.323 client and the SCOPIA PathFinder
Client, all ports must be opened in both directions (1024-65535). We therefore recommend no
firewall between the endpoint and the SCOPIA PathFinder Client.
