H.323 Ports  
 
Static 
When selecting static H.323 ports for TCP connections the ports 5555 to 5574 
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. 
When selecting Dynamic, the H.323 ports used are from 11000 to 65535. Once 
65535 is reached they restart again at 11000.
