Configuring H.323 settings

To display the H.323 settings page, go to Settings > H.323.

The H.323 settings page displays the list of gatekeepers configured on the IP gateway. It also shows the IP address and the status of the gatekeepers, and the ports by which each gatekeeper is physically attached to the IP gateway.

You can configure up to two H.323 gatekeepers on the IP gateway. Where there are two gatekeepers, they must both be physically on different networks, that is, attached to different ports. You can only associate a maximum of one gatekeeper with each port. The gatekeeper that is associated with a port is the one that the IP gateway will query when a call is incoming or outgoing on that port (although there can be exceptions to this, see below).

To add a new H.323 gatekeeper, select Add gatekeeper.

To delete a configured gatekeeper, check the one you want to delete and select Delete selected.

To edit the settings of a configured gatekeeper, click the name of the gatekeeper (refer to Configuring gatekeeper settings).

To associate a gatekeeper with a port, configure the H.323 settings at the bottom of the H.323 settings page.

Field	Field description
Name	The name of the gatekeeper.
Address	The IP address or host name of the gatekeeper.
IP route	The port via which the gatekeeper is connected or in the case of the built-in gatekeeper: Both ports (Internal GK). If a gatekeeper is on the subnet local to either port, the IP gateway will list that port here. Otherwise, the IP gateway will use the IP routes (configured on the Network > Routes page) to determine on which port the gatekeeper is to be found. For example, there might be a route configured to the gatekeeper's subnet or the IP gateway will use the default route. Usually, the port with which the gatekeeper is associated will be the same port as the one to which the gatekeeper is connected. The exception to this is the built-in gatekeeper which will both appear to be connected to both ports and can be used to bridge between two networks and associated with both ports.
Status	For an enabled gatekeeper, the number of active registrations and the number of pending registrations are displayed. If this gatekeeper usage is disabled, that is indicated here. A control to enable/disable this gatekeeper is provided here. Note that if you disable the gatekeeper here, you are disabling the IP gateway's ability to register to this gatekeeper, rather than disabling the gatekeeper itself (which for the built-in gatekeeper you can do on the Built-in gatekeeper page).

Field	Field description
Port A / Port B associated gatekeeper	The drop-down selection box lists the gatekeepers configured on the IP gateway. If you want to associate a gatekeeper with a port, select it here. The associated gatekeeper for a port is the gatekeeper to which the IP gateway sends a query for all incoming connections on that port, and for all outgoing connections on that port that are dialed by address rather than by E.164 phone number (unless the dial plan or the configuration of an endpoint specifies otherwise). By querying the gatekeeper, the IP gateway ascertains whether or not the gatekeeper permits the call. If no gatekeeper is associated with a port, either here or explicitly in a dial plan rule (refer to Adding and updating dial plan rules), the IP gateway will always make (for outgoing calls) or accept (for incoming calls) the call. That is, the IP gateway will not require validation from a gatekeeper before handling a call on that port. One gatekeeper can be associated with both ports; one port can have a maximum of one associated gatekeeper.
Port A / Port B gatekeeper required	If you want all calls arriving on a port to be controlled by a gatekeeper, configure the port as 'gatekeeper required'. Where a gatekeeper is required, calls cannot be made without querying a gatekeeper. Leave this checkbox unselected if you want the call to be connected if possible even without querying a gatekeeper. If a port is configured as 'gatekeeper required', and if the queried gatekeeper does not respond to a query regarding a call, the IP gateway will reject the call (if the query was regarding an incoming call) or not make the call (if the query was regarding an outgoing call). If a port is configured as 'gatekeeper required', this setting will be imposed by the IP gateway whether it is the gatekeeper associated with the port that is used or whether a dial plan rule or a configured endpoint's settings dictate the use of a different gatekeeper.

Port A / Port B gatekeeper required

If you want all calls arriving on a port to be controlled by a gatekeeper, configure the port as 'gatekeeper required'. Where a gatekeeper is required, calls cannot be made without querying a gatekeeper.

Leave this checkbox unselected if you want the call to be connected if possible even without querying a gatekeeper.

If a port is configured as 'gatekeeper required', and if the queried gatekeeper does not respond to a query regarding a call, the IP gateway will reject the call (if the query was regarding an incoming call) or not make the call (if the query was regarding an outgoing call).

If a port is configured as 'gatekeeper required', this setting will be imposed by the IP gateway whether it is the gatekeeper associated with the port that is used or whether a dial plan rule or a configured endpoint's settings dictate the use of a different gatekeeper.
