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.

Primary Gatekeeper field. You must choose Specify to enable H.235 Annex D
