Note
A Gatekeeper is not required to make IP-to-IP LAN calls. In
these situations, select the Off option.
•Specify: To specify a Gatekeeper, select the Specify option
and enter the Gatekeeper’s IP address or name (for
example, gatekeeper.companyname.usa.com) in the
Gatekeeper’s IP Address field. This information is
available from your network administrator.
•Auto: To have system automatically find an available
Gatekeeper, select the Auto option.
❑ Gatekeeper IP Address—If you have selected Specify under
Use Gatekeeper, enter the Gatekeeper’s IP address or name in
this field.
❑ Outbound Call Route—The Outbound Call Route via ISDN or
Gateway only affects how a system dials an ISDN (H.320) call.
All IP (H.323) calls are not affected by this option.
Currently, a system can dial an ISDN call through ISDN or
Gateway as long as it has native ISDN capability and the system
is registered with a Gatekeeper. Select the appropriate option
depending on your network configuration:
• Gateway: Select this option if your outbound call needs to
be handled by a Gateway. This information can be obtained
from your network administrator.
•ISDN: Select this option if your system is connected to an
ISDN line. ISDN is the default.
When you dial through ISDN, the ISDN call is made by using
ISDN natively. All the prefix or suffix on the Gateway screen
are irrelevant.
When you dial through Gateway, the ISDN call is made by
using Gateway, not ISDN natively. If there is prefix or suffix on
the Gateway screen for Gateway calls, it should be included
when a call is made.
