H323 Profile [1..1] H323Alias ID
Lets you specify the H.323 Alias ID which is used to address the system on a H.323 Gatekeeper and will
be displayed in the call lists. Example: “firstname.surname@company.com”, “My H.323 Alias ID”.
Valuespace: <S: 0, 49>
Format: String with a maximum of 49 characters
Example: H323 Prole 1 H323Alias ID: “rstname.surname@company.com”
H323 Profile [1..1] PortAllocation
The H.323 Port Allocation setting affects the H.245 port numbers used for H.323 call signalling.
Valuespace: <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 Prole 1 PortAllocation: Dynamic
Network [1..1] Assignment
Defines whether to use DHCP or Static IP assignment.
Changes to this setting requires a restart of the codec.
Valuespace: <Static/DHCP>
Static: The IP Address, Subnet Mask and Default Gateway for the system must be specified in the
respective address fields.
DHCP: The system adresses are automatically assigend by the DHCP server.
Example: Network 1 Assignment: DHCP
Network [1..1] DNS Domain Name
DNS Domain Name is the default domain name suffix which is added to unqualified names.
Example: If the DNS Domain Name is “company.com” and the name to lookup is “MyVideoSystem”, this
will result in the DNS lookup “MyVideoSystem.company.com”.
Valuespace: <S: 0, 64>
Format: String with a maximum of 64 characters.
Example: Network 1 DNS Domain Name: “company.com”
Network [1..1] DNS Server [1..5] Address
Defines 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.
Valuespace: <S: 0, 64>
Format: String with a maximum of 64 characters.
Example: Network 1 DNS Server 1 Address: “”
Network [1..1] IEEE8021X AnonymousIdentity
The 802.1X Anonymous ID string is to be used as unencrypted identity with EAP types that support
different tunneled identity, like EAP-PEAP and EAP-TTLS. If set, the anonymous ID will be used for the
initial (unencrypted) EAP Identity Request.
Valuespace: <S: 0, 64>
Format: String with a maximum of 64 characters.
Example: Network 1 IEEE8021X AnonymousIdentity: “”
