H323 settings

H323 NAT Mode

The firewall traversal technology creates a secure path through the firewall barrier, and enables

proper exchange of audio/video data when connected to an external video conferencing

system (when the IP traffic goes through a NAT router). NOTE: NAT does not work in

conjunction with gatekeepers.

Requires user role: ADMIN
Value space: <Auto/Off/On>

Auto: The system will determine if the H323 NAT Address or the real IP address should be

used in signaling. This makes it possible to place calls to endpoints on the LAN as well as

endpoints on the WAN. If the H323 NAT Address is wrong or not set, the real IP address will

be used.
Off: The system will signal the real IP address.
On: The system will signal the configured H323 NAT Address instead of its real IP address

in Q.931 and H.245. The NAT Server Address will be shown in the startup-menu as: "My IP

Address: 10.0.2.1". If the H323 NAT Address is wrong or not set, H.323 calls cannot be set

up.

Example:

H323 NAT Mode: Off

H323 NAT Address

Enter the external/global IP address to the router with NAT support. Packets sent to the

router will then be routed to the system. Note that NAT cannot be used when registered to a

gatekeeper.
In the router, the following ports must be routed to the system's IP address:
* Port 1720
* Port 5555-6555
* Port 2326-2487

Requires user role: ADMIN
Value space: <S: 0, 64>

Format: A valid IPv4 address or IPv6 address.

Example:

H323 NAT Address: ""

H323 Profile [1..1] Authentication Mode

Set the authentication mode for the H.323 profile.

Requires user role: ADMIN
Value space: <Off/On>

Off: If the H.323 Gatekeeper Authentication Mode is set to Off the system will not try to

authenticate itself to a H.323 Gatekeeper, but will still try a normal registration.
On: If the H.323 Gatekeeper Authentication Mode is set to On and a H.323 Gatekeeper

indicates that it requires authentication, the system will try to authenticate itself to the

gatekeeper. Requires the Authentication LoginName and Authentication Password to be

defined on both the codec and the Gatekeeper.

Example:

H323 Profile 1 Authentication Mode: Off

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.

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:

H323 Profile 1 Authentication LoginName: ""
