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
