TANDBERG D1389801 user manual 3 H.323 ports, Use static ports

4.1.3 H.323 ports

The H.323 ports configuration menu contains the following settings:

ƒUse static ports

ƒTCP

ƒUDP

.

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.
