H323 Profile [1..1] PortAllocation
The H.323 Port Allocation setting affects the H.245 port numbers used for H.323 call signalling.
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].
Example: H323 Profile 1 PortAllocation: Dynamic

The Network settings

Network [1..1] DNS Domain Name

Network [1..1] DNS Server [1..5] Address
Define the network addresses for DNS servers. Up to 5 addresses may be specified. If the network
addresses are unknown, contact your administrator or Internet Service Provider.
Value space: <S: 0, 64>

Network [1..1] Assignment
Define whether to use DHCP or Static IP assignment. NOTE! Changes to this setting requires a restart of
the codec.
Value space: <Static/DHCP>
Static: When you set the network assignment to Static you must configure the static IP settings.
Configure the settings: Network IPv4 Address, Network IPv4 SubnetMask and Network IPv4 Gateway.
DHCP: The system adresses are automatically assigend by the DHCP server.
Example: Network 1 Assignment: DHCP
Network [1..1] IPv4 Address
Define the static IP network address for the system. Only applicable if the Network Assignment is set to
Static.
Value space: <S: 0, 64>
Format: Only the valid IP address format is accepted. An IP address that contains letters (192.a.2.0) or
unvalid IP addresses (192.0.1234.0) will be rejected.
Example: Network 1 IPv4 Address: "192.0.2.0"
