Endpoint Support Authentication and Integrity verification
Verifies that the sender and receiver of a message are, in fact, who they say they are
Verifies that data has not been altered in an unauthorized manner
Whenever an endpoint sends a message to the Gatekeeper, the endpoint encrypts the message using the password.The Gatekeeper receiving the message authenticates the message using the same password. If one of the parties does not have the correct password, the authentication fails and the transaction is rejected.

Alternate Gatekeepers allow the endpoint to register and call the destination when the original GK goes down.
This is accomplished with a Hot standby GK that receives al information from the operating GK. It is knows if the operating GK goes down, and automatically assumes the GK's IP and full operation.
When the original GK goes up, it then becomes the slave of the now operating GK.
