4.1.3 H.323 ports 
 
 
The H.323 ports configuration menu contains the following settings: 
 
ƒ
  Use static ports  
ƒ
 TCP 
ƒ
 UDP 
 
 
 
 
 
 
Use static ports 
‘Use static ports’ is disabled by default. This means that the system 
will dynamically allocate which ports to use when opening a 
TCP/UDP connection. The reason for doing this is to avoid using the 
same ports for subsequent calls as some firewalls consider this as a 
sign of attack. 
Static ports can be enabled by selecting the checkbox and 
specifying the required range of ports. 
TCP 
 
Standard firewall port range. 
UDP 
Standard firewall port range.
