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: xConguration H323 Prole 1 H323Alias ID: "rstname.surname@company.
com"
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 to 9, * and #.
Example: xConguration H323 Prole 1 H323Alias E164: "90550092"
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: xConguration H323 Prole 1 CallSetup Mode: Gatekeeper
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: xConguration H323 Prole 1 Gatekeeper Address: "192.0.2.0"
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: xConguration H323 Prole 1 Gatekeeper Discovery: Manual
H323 Profile [1..1] Authentication LoginName
The system sends the Authentication Login Name and the Authentication Password to a H.323
Gatekeeper for authentication. The authentication is a one way authentication from the codec to
the H.323 Gatekeeper, i.e. the system is authenticated to the gatekeeper. If the H.323 Gatekeeper
indicates that no authentication is required, the system will still try to register. NOTE: Requires the H.323
Gatekeeper Authentication Mode to be enabled.
Requires user role: ADMIN
Value space: <S: 0, 50>
Format: String with a maximum of 50 characters.
Example: xConguration H323 Prole 1 Authentication LoginName: ""
H323 Profile [1..1] Authentication Password
The system sends the Authentication Login Name and the Authentication Password to a H.323
Gatekeeper for authentication. The authentication is a one way authentication from the codec to
the H.323 Gatekeeper, i.e. the system is authenticated to the gatekeeper. If the H.323 Gatekeeper
indicates that no authentication is required, the system will still try to register. NOTE: Requires the H.323
Gatekeeper Authentication Mode to be enabled.
Requires user role: ADMIN
Value space: <S: 0, 50>
Format: String with a maximum of 50 characters.
Example: xConguration H323 Prole 1 Authentication Password:
