ADMINISTRATOR GUIDE
H323Profile[1..1]CallSetupMode
The H.323 Call Setup Mode defines whether to use a Gatekeeper or Direct calling when
establishing H323 calls.
NOTE: Direct H.323 calls can be made even though the H.323 Call Setup Mode is set to
Gatekeeper.
Requiresuserrole: ADMIN
Valuespace: <Direct/Gatekeeper>
Direct: An IP-address must be used when dialling in order to make the H323 call.
Gatekeeper: The system will use a Gatekeeper to make a H.323 call. When selecting this
option the H323 Profile Gatekeeper Address and H323 Profile Gatekeeper Discovery settings
must also be configured.
Example: H323 Profile 1 CallSetup Mode: Gatekeeper
H323Profile[1..1]GatekeeperDiscovery
Determine how the system shall register to a H.323 Gatekeeper.
Requiresuserrole: ADMIN
Valuespace: <Manual/Auto>
Manual: The system will use a specific Gatekeeper identified by the Gatekeeper's IP-address.
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 IP-address must be specified manually.
Example: H323 Profile 1 Gatekeeper Discovery: Manual
H323Profile[1..1]GatekeeperAddress
Enter the IP address of the Gatekeeper. NOTE: Requires the H.323 Call Setup Mode to be set to
Gatekeeper and the Gatekeeper Discovery to be set to Manual.
Requiresuserrole: ADMIN
Valuespace: <S: 0, 255>
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: H323 Profile 1 Gatekeeper Address: "192.0.2.0"
H323Profile[1..1]H323AliasE164
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.
Requiresuserrole: ADMIN
Valuespace: <S: 0, 30>
Format: Compact string with a maximum of 30 characters. Valid characters are 0-9, * and #.
Example: H323 Profile 1 H323Alias E164: "90550092"
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"
Requiresuserrole: ADMIN
Valuespace: <S: 0, 49>
Format: String with a maximum of 49 characters
Example: H323 Profile 1 H323Alias ID: "firstname.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.
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].
Example: H323 Profile 1 PortAllocation: Dynamic
