Telecommunication Union (ITU) in 1996 to promote compatibility in videoconference
transmissions over IP networks. It is now considered to be the standard for interoperability in
audio, video and data transmissions as well as Internet phone and voice-over-IP (VoIP) because it
addresses call control and management for both point-to-point and multipoint conferences as well
as gateway administration of media traffic, bandwidth and user participation.

Gatekeeper Mode, and Advance Settings. Refer to the figure above for the configuration page.
5.4.1.1 Gatekeeper Mode
The Gatekeeper (GK) is an H.323 entity on the network that provides address translation and
controls access to the network for H.323 terminals, Gateways and MCUs. The Gatekeeper may
also provide other services to the terminals, Gateways and MCUs such as bandwidth management
and locating Gateways.
If you select the gatekeeper mode, there will be several items needed to be set up as follows:
Gatekeeper Address, Phone Number, Display Name, Unconditional Forward Number, No
Reply Forward Number, Busy Forward Number and Enable AUTH (Auth ID and
Password) .
Gatekeeper Address is used for finding the correct gatekeeper. It may be an IP address such as
192.168.2.1 or a domain name like gk.yourisp.com. On the Call Settings screen, enter the
gatekeeper address in the

telephone network. For example, 5551234 is a valid phone number. On the Call Settings screen,
