2.2 Functionality and Features of H.323 Gatekeeper
2.2.1 Registration Management
An endpoint, after discovering a gatekeeper providing service for it, must register with
the gatekeeper before it can access the zone of this gatekeeper.
When the gatekeeper receives the RRQ message from the endpoint on its default RAS
port 1719 (you can change the RAS port to another one), it makes registration decision
based on the information contained in the message.
In the RRQ, the endpoint provides two IP addresses: one for transmitting/receiving
RAS signaling, and the other for call signaling.
