H323 Profile [1..1] PortAllocation

The H.323 Port Allocation setting affects the H.245 port numbers used for H.323 call signaling.
Requires user role: ADMIN
Value space: <Dynamic/Static>
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
firewalls consider this as a sign of attack. When Dynamic is selected, the H.323 ports used
are from 11000 to 20999. Once 20999 is reached they restart again at 11000. The ports are
automatically selected by the system within the given range. Firewall administrators should
not try to deduce which ports are used when, as the allocation schema within the mentioned
range may change without any further notice.
Static: When set to Static the ports are given within a static predefined range [5555-6555].
