Chapter 7 - Configuring the Gateway

Double Gateway

7-68
The Double Gateway feature enables a call session to be routed through
multiple Gateways, avoiding the cost of long distance charges, optimizing
gateway usage and by-passing firewalls. The Double Gateway provides each
endpoint with a connection to a local gateway and routes the long distance
connection of a call between two "local" gateways on different networks.
It is strongly recommended to configure two Single Gateways prior to configuring
the Double Gateway.
The Double Gateway functionality is in essence a Local Gateway, whose Party-
out reaches a Remote Gateway Party-In, and then invokes the Address Book,
H.323 Destinations, or Forwarding Services on the Remote Gateway. It is based
on the Single Gateway methodology that uses the similar principles.
The Gateway Configuration tree includes the following entries, ranked in the
order in which the user should define them:
