○ Use Gatekeeper A gatekeeper manages functions such as bandwidth control and admission
control. The gatekeeper also handles address translation, which enables users to make calls
using static aliases instead of IP addresses that may change each day. You can choose from the
following options:
» Off Calls do not use a gatekeeper. If you choose Off, the Primary Gatekeeper IP Address
field is not displayed.
» Auto This option causes the HDX system to attempt to automatically find an available
gatekeeper.
» Specify When you choose this option, calls you dial use the gatekeeper you specify in the
Primary Gatekeeper field. You must choose Specify to enable H.235 Annex D
Authentication.
» Specify with PIN Choose this option to use the E.164 address you specify in the H.323
Extension (E.164) field. Calls you make using this option require an authentication PIN. Note
that gateways and gatekeepers are required for calls between IP and ISDN.
○ Authentication Check this option to enable support for H.235 Annex D Authentication. When
you enable this option, the H.323 gatekeeper ensures that only trusted H.323 endpoints are
allowed to access the gatekeeper. The following fields display when you enable Authentication:
» User Name Specify the user name for authentication with H.235 Annex D.
» Password Specify the password for authentication with H.235 Annex D.
• Current Gatekeeper IP Address This field is not configurable and displays the IP address that the
HDX is currently registered to.
• Primary Gatekeeper IP Address The primary gatekeeper IP address contains the address with
which the system registers. As part of the gatekeeper registration process, the gatekeeper might
return alternate gatekeepers. If communication with the primary gatekeeper is lost, the HDX
system registers with the alternate gatekeeper but continues to poll the primary gatekeeper. If
the system reestablishes communications with the primary gatekeeper, the HDX system
unregisters from the alternate gatekeeper and reregisters with the primary gatekeeper. Note that
this field does not display if you chose Off in the Use Gatekeeper field.
○ If you chose to use an automatically selected gatekeeper, this field displays the gatekeeper’s IP
address.
○ If you chose to specify a gatekeeper, enter the gatekeeper’s IP address or name (for example,
gatekeeper.companyname.usa.com, or 10.11.12.13).
• Use PathNavigator for Multipoint Calls Specify whether multipoint calls use the system’s
internal multipoint capability or the Conference on Demand feature available with Polycom
PathNavigator™, ReadiManager® SE200, or Polycom CMA system. This feature is available only if
the system is registered with one of these gatekeepers.
