Configuring IP Settings
Specifying H.323 Settings
If your network uses a gatekeeper, the system can automatically register its
H.323 name and extension. This allows others to call the system by entering
the H.323 name or extension instead of the IP address.
To specify H.323 settings:
1. Go to System > Admin Settings > Network > IP > H.323 Settings.
2. Configure these settings on the H.323 Settings screen:
Configuring the System to Use a Gatekeeper
A gatekeeper is a “network administrator” that supervises network traffic and
manages functions such as bandwidth control and admission control. The
gatekeeper also handles address translation, which allows users to make calls
using static aliases instead of IP addresses that may change each day.
Setting Description
Display H.323
Extension Lets users placing a gateway call enter the H.323 extension
separately from the gateway ID.
If you do not select this setting, users make gateway calls by
entering the call information in this format:
gateway ID + ## + extension
H.323 Name Specifies the name that gatekeepers and gateways use to
identify this system. You can make point-to-point calls using
H.323 names if both systems are registered to a gatekeeper.
The H.323 Name is the same as the System Name, unless
you change it. Your organization’s dial plan may define the
names you can use.
H.323 Extension
(E.164) Lets users place point-to-point calls using the extension if both
systems are registered with a gatekeeper, and specifies the
extension that gatekeepers and gateways use to identify this
system.
The default H.323 Extension can be changed. Your
organization’s dial plan may define the extensions you can
use.
