Use this procedure to prepare the dial plan infrastructure in VRC.
Prerequisite: Your elements have already been added to the topology, gateways must have voice ports configured, and you are in the Design View.
If you have not added the elements to the topology, refer to Adding Elements to the Topology.
Once you have added elements to the topology, you must set the parameters for the Administrative Domain and create regions.
For the Administrative Domain (AD):
Choose the routing type.
Add trunk or carrier IDs as needed.
For each region you create:
Create a directory gatekeeper group (DGKGrp) if you want the region to be hierarchical.
Assign directory gatekeepers (DGKs) to the directory gatekeeper group.
Create gatekeeper groups (GKGrps).
Assign gatekeepers to the gatekeeper groups.
Create zones.
Assign gateways to the zones.
