Configuring the System to Use a Gateway
A gateway performs code and protocol conversion between H.323 (IP), SIP,
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 on the Gateway
screen:
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.
In order to place calls using PathNavigator, you need to:
•Register your Polycom HDX system with PathNavigator.
•Configure your Polycom HDX system to use PathNavigator for multipoint calls
(see Configuring the System to Use a Gatekeeper on page 2-4).
•Create a multi-site entry in the directory (recommended).
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.
