A zone alias is the name a gatekeeper assigns to a local zone name.
VRC creates a zone alias during the Discovery operation, or you can enter a zone alias manually.
When a gateway registers with a gatekeeper, it uses the zone alias name.
Note: A managed zone must have one zone alias for every gatekeeper in the gatekeeper group.
Use this procedure to manually add a zone alias for a zone.
You must be in the Design View to add a zone alias for a zone.
Expand the dial plan tree to view all components.
Locate the zone you want to create a zone alias for.
Click the Zone Aliases tab.
Right-click and choose Add from the menu. The Add Zone Alias dialog box appears.
Enter the following values:
Name - The local zone name for a zone for a particular gatekeeper. Maximum value is 64 characters. The name must be unique in the AD.
Note: If the gatekeeper referenced in this zone alias has the Type parameter set to primary or backup, and another gatekeeper in the same gatekeeper group is also a primary or backup, the zone alias in this zone must be identical for those two gatekeepers.
Gatekeeper - The gatekeeper for which the local zone name is used. You can only choose from the gatekeepers in the gatekeeper group referenced by the zone associated with this alias.
