Gatekeepers that the system can use if the primary gatekeeper is not

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:
Points to note about PathNavigator’s Conference on Demand feature:
If your organization uses Polycom’s PathNavigator, you can use PathNavigator’s
Conference on Demand feature to place multipoint calls with up to 10 sites.
In order to place calls using PathNavigator, you need to:
• Register your VSX system with PathNavigator.
• Configure your VSX system to use PathNavigator for multipoint calls (see
Configuring the System to Use a Gatekeeper on page 3-7).
• Create a multi-site entry in the directory.
When using PathNavigator’s Conference on Demand:
• Once the call begins, users cannot add another site to the call — even if the site
was in the call originally.
• The MGC™ needs to have enough ports available to complete the call. If it does
not, the call disconnects.
