Using PathNavigator's Conference on Demand Feature
Configuring the System to Use a Gateway
3 - 8
Setting Description
Outbound Call For systems using a gatekeeper, specifies whether calls initiated
Route by this system should be handled as IP calls sent through a
gateway or as ISDN.
Gatekeeper IP If you chose to use an automatically selected gatekeeper, this
Address area displays the gatekeeper's IP address.
If you chose to specify a gatekeeper, enter the IP address here.
Alternate If you chose to specify a gatekeeper, you can specify other
Gatekeepers gatekeepers that the system can use if the primary gatekeeper is
not available.
Use Lets you specify whether multipoint calls use the system's internal
PathNavigator for multipoint capability or the PathNavigator Conference on Demand
Multipoint Calls feature. This feature is available only if the system is:
VSX 3000
Configured for multipoint calling, and
VSX 7000
Registered with a PathNavigator gatekeeper.
VSX 8000
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
the System to Use a Gatekeeper on page
• 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.
A gateway performs code and protocol conversion between IP and 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.
