services.
• Off: Calls don't use a gatekeeper.
• Auto: System tries to automatically find an available
gatekeeper.

must select this setting to enable H.235 Annex D
Authentication.
If you don't configure this setting to Off, a registration

Enables support for H.235 Annex D Authentication.
When you enable H.235 Annex D Authentication, the
H.323 gatekeeper ensures that only trusted H.323
endpoints can access the gatekeeper.
This setting is available when you set Use Gatekeeper
to Specify.
When authentication is required, specifies the user
name for authentication with H.235 Annex D.
When authentication is required, specifies the
password for authentication with H.235 Annex D.
Displays the IP address that the gatekeeper is using.
If you select Off for the Use Gatekeeper field, the
Current Gatekeeper IP Address field doesn't display.
The gatekeeper IPv4 address the system registers
with. As part of the registration process, the gatekeeper
might return alternate gatekeepers. If your system
loses communication with the primary gatekeeper, your
system registers with the alternate gatekeeper but
continues to poll the primary gatekeeper. If the system
re-establishes communication with the primary
gatekeeper, it unregisters from the alternate
gatekeeper.
• If you set the Use Gatekeeper field to Off, the
Primary Gatekeeper IP Address field doesn't
display.
• If you use an automatically selected gatekeeper,
this area displays the gatekeeper's IP address.
• If you specify a gatekeeper, enter the gatekeeper IP
address or name (for example, 10.11.12.13 or
gatekeeper.companyname.usa.com).
