The H323 Profile settings, continued...
H323 Profile [1..
1] Gatekeeper Discovery:
<Manual/Auto>
Determines how the system shall register to a H.323 Gatekeeper.
Manual: The system will use a specific Gatekeeper identified by the Gatekeeper’s
Auto: The system will automatically try to register to any available Gatekeeper. If a Gatekeeper responds to the request sent from the codec within 30 seconds this specific Gatekeeper will be used. This requires that the Gatekeeper is in auto discovery mode as well. If no Gatekeeper responds, the system will not use a Gatekeeper for making H.323 calls and hence an
Example: H323 Profile 1 Gatekeeper Discovery: Manual
H323 Profile [1..
1] H323Alias E164:
<S:
0, 30>
The H.323 Alias E.164 defines the address of the system, according to the numbering plan implemented in the H.323 Gatekeeper. The E.164 alias is equivalent to a telephone number, sometimes combined with access codes.
Format: Compact string with a maximum of 30 characters. Valid characters are
Example: H323 Profile 1 H323Alias E164: “90550092”
The Network settings
Network [1..
1] Assignment:
<Static/DHCP>
Defines whether to use DHCP or Static IP assignment.
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. Changes to this setting requires a restart of the codec.
Example: Network 1 Assignment: DHCP
Network [1..
1] DNS Domain Name:
<S:
0, 64>
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”.
Format: String with a maximum of 64 characters.
Example: Network 1 DNS Domain Name: “company.com”
H323 Profile [1..
1] H323Alias ID:
<S:
0, 49>
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”
Format: String with a maximum of 49 characters
Example: H323 Profile 1 H323Alias ID: “firstname.surname@company.com”
Network [1..
1] DNS Server [1..
5] Address:
<S:
0, 64>
Defines the network addresses for DNS servers. Up to 5 addresses may be specified. If the network addresses are unknown, please contact your administrator or Internet Service Provider.
Format: String with a maximum of 64 characters.
Example: Network 1 DNS Server 1 Address: “”
H323 Profile [1..
1] PortAllocation:
<Dynamic/Static>
The H.323 Port Allocation setting affects the H.245 port numbers used for H.323 call signalling.
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
Example: H323 Profile 1 PortAllocation: Dynamic
Network [1..
1] IEEE8021X AnonymousIdentity:
<S:
0, 64>
The 802.1X Anonymous ID string is to be used as unencrypted identity with EAP types that support different tunneled identity, like
Format: String with a maximum of 64 characters.
Example: Network 1 IEEE8021X AnonymousIdentity: “”
