4.1.3 H.323 ports
The H.323 ports configuration menu contains the following settings:
Use static ports
TCP
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.
