Configuring IP Settings

Specifying H.323 Settings

If your network uses a gatekeeper, the system can automatically register its H.323 name and extension. This allows others to call the system by entering the H.323 name or extension instead of the IP address.

To specify H.323 settings:

1.Go to System > Admin Settings > Network > IP > H.323 Settings.

2.Configure these settings on the H.323 Settings screen:

Setting	Description
Display H.323	Lets users placing a gateway call enter the H.323 extension
Extension	separately from the gateway ID.
	If you do not select this setting, users make gateway calls by
	entering the call information in this format:
	gateway ID + ## + extension
H.323 Name	Specifies the name that gatekeepers and gateways use to
	identify this system. You can make point-to-point calls using
	H.323 names if both systems are registered to a gatekeeper.
	The H.323 Name is the same as the System Name, unless
	you change it. Your organization’s dial plan may define the
	names you can use.
H.323 Extension	Lets users place point-to-point calls using the extension if both
(E.164)	systems are registered with a gatekeeper, and specifies the
	extension that gatekeepers and gateways use to identify this
	system.
	The default H.323 Extension can be changed. Your
	organization’s dial plan may define the extensions you can
	use.

Configuring the System to Use a Gatekeeper

A gatekeeper is a “network administrator” that supervises network traffic and manages functions such as bandwidth control and admission control. The gatekeeper also handles address translation, which allows users to make calls using static aliases instead of IP addresses that may change each day.
