Configuring Ip Network Support - Polycom V500 System Administrator's Manual

Configuring IP Network Support

After you have configured LAN properties and set up your IP network
connection, you need to configure IP network support if you plan on making
IP video calls.
Configuring H.323 Settings
Before you can make any IP video calls, you must check the Enable IP H.323
setting on the Call Preferences screen, as described on page 3-20. You can then
configure the H.323 settings by following the steps in this section.
H.323 settings enable you to set up H.323, as well as set up gatekeepers and
gateways:
• A gatekeeper supervises network traffic and manages functions such as
bandwidth control and admission control. The gatekeeper also handles
address translation, which allows you to make calls using static aliases
instead of IP addresses that can change each day.
• A gateway performs code and protocol conversion between IP networks
and ISDN, so that users on different networks can call one another. If the
system is configured to use a gateway, you must also configure it to use a
gatekeeper.
To configure H.323 settings:
1. Go to System > Admin Settings > Network > IP > H.323 Settings.
2. Configure these settings:
Setting Description
Display H.323 Lets you place gateway calls by entering the H.323 extension
Extension separately from the gateway ID.
If you do not check this box, you can make gateway calls by
entering the call information in this format:
gateway ID + TCS4 delimiter + extension
To determine your TCS4 delimiter, ask your network provider.
H.323 Name Specifies the name that gatekeepers and gateways can 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 dial plan may define the names you can
use.
H.323 Extension You can place point-to-point calls using the extension if both
(E.164) systems are registered with a gatekeeper.
You can change the default H.323 Extension. Your dial plan
may define the extensions you can use.
