H.323 Ports
Static
When selecting static H.323 ports for TCP connections the ports 5555 or
5556 will be used for Q.931 and H.245 respectively.
Dynamic
The system will allocate which ports to use when opening a TCP
connection. The reason for doing this is to avoid using the same ports for
subsequent calls as some firewall consider this as a sign of attack.
