Gatekeepers
A Gatekeeper is a software application that makes network conferencing simpler. It
provides management services and user-friendly features for dialing other systems.
Every conferencing system that registers with the Gatekeeper provides its User
Number (also called an E.164 Number) and a User Name (also called an H.323
Alias). The Gatekeeper keeps a database so it can map between the IP address, the
User Number and the User Name of each system. Therefore, you can dial these
numbers or names instead of IP addresses.
User Numbers and Names are static. They do not change, as long as a system
remains registered with the same Gatekeeper. IP addresses are usually dynamic;
they may change without notification. Ask your system administrator for your User
Number and Name.
