xConfiguration 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].
