Configuring IP Network Support
Use the following sections to configure the system so that you can place and
receive video calls using IP on your LAN or WAN:
❑ H.323 Settings, including Gatekeeper and Gateway
❑ SIP Settings
❑ Quality of Service
❑ Firewall or NAT
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:
Setting Description
Enable IP H.323 Specifies whether to allow IP dialing.
Display H.323
Extension
Lets you place a gateway call by entering the H.323 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
Check with your network provider to determine your TCS4
delimiter.
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 dial plan may define the names you can use.
H.323 Extension
(E.164)
Lets you place point-to-point calls using the extension if both
systems are registered with a gatekeeper.
The default H.323 Extension is based on the system serial
number, but it can be changed. Your dial plan may define the
extensions you can use.
