Configuring the System to Use a Gateway

A gateway performs protocol conversion between IP and ISDN networks, so that

users on different networks can call one another. If the syste m is confi gured to u se

a gateway, you must also configure it to use a gatekeeper.

To configure the system to use a gateway:

1. Go to System Info > Admin Setup > LAN/H.323 > H.323 > Gateway.

2. Configure these settings:
Use Gatekeeper Specifies whether to use a gatekeeper. Gateways and
gatekeepers are required for calls between IP and ISDN networks.
• Off — Calls do not use a gatekeeper.
• Specify — Calls use the specified gatekeeper. Enter the
gatekeeper’s IP address or name (for example,
gatekeeper.companyname.usa.com, or
255.255.255.255).
•Auto — System automatically finds an available gatekeeper.
•The system restarts if you change this setting.
Gatekeeper IP
Address Displays the gatekeeper’s IP address. If you chose to specify a
gatekeeper, enter the IP address here.
The system restarts if you change this setting.
Outbound Call
Route For systems using a gatekeeper, specifies whether calls initiated
by this system should be handled as IP calls sent through a
gateway or as ISDN.
Dial Multipoint Calls

multipoint capability or the PathNavigator Conference on Demand
feature. This feature is available only if the system is:
•Configured for multipoint calling.
•Registered with a PathNavigator gatekeeper.
