Configuring the System to Use a Gateway

A gateway performs code and protocol conversion between H.323 (IP) and H.320 (ISDN), so that users on different networks can call one another. If the system is configured to use a gateway, you must also configure it to use a gatekeeper.

To configure the system to use a gateway:

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

2.Select two or three times and configure these settings:

Setting	Description
Country Code	Specifies the country code for the system’s location.
Area Code	Specifies the area or city code for the system’s location.
Number	Specifies the gateway’s number.
H.323 Extension	Specifies the extension that identifies this system for incoming
(E.164)	gateway calls.
	The default H.323 Extension can be changed.
