xConfiguration H323 Profile [1..1] PortAllocation
The H.323 Port Allocation setting affects the H.245 port numbers used for H.323 call signalling.
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. For RTP and RTCP media data, the system is using UDP
ports in the range 2326 to 2487. Each media channel is using two adjacent ports, ie 2330 and 2331
for RTP and RTCP respectively. 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].

xCommand
Select which internet protocols the system will support.
NOTE: Restart the system after changing this setting.
Requires user role: ADMIN
Value space: <IPv4/IPv6>
IPv4: IP version 4 is used for the SIP and H323 calls.
IPv6: IP version 6 is used for the SIP and H323 calls.
example: xConfiguration Network 1 IPStack: IPv4
Define how the system will obtain its IPv4 address, subnet mask and gateway address. This setting only
applies to systems on IPv4 networks.
Requires user role: ADMIN
Value space: <Static/DHCP>
Static: The addresses must be configured manually using the Network IPv4 Address, Network IPv4
Gateway and Network IPv4 SubnetMask settings (static addresses).
DHCP: The system addresses are automatically assigned by the DHCP server.
example: xConfiguration Network 1 Assignment: DHCP
Enter the static IPv4 network address for the system. This setting is only applicable when Network
Assignment is set to Static.
Requires user role: ADMIN
Value space: <S: 0, 64>
Format: Only the valid IPv4 address format is accepted.
example: xConfiguration Network 1 IPv4 Address: "192.0.2.0"
Define the IPv4 network gateway. This setting is only applicable when the Network Assignment is set
to Static.
Requires user role: ADMIN
Value space: <S: 0, 64>
Format: Only the valid IPv4 address format is accepted.
example: xConfiguration Network 1 IPv4 Gateway: "192.0.2.0"
