About the Discovery Process

This topic provides more information about how the VRC Discovery process works.

VRC reads the dial plan configuration for each element on a region by region basis. Within each region, the dial plan configuration is read in the following order:

  1. Gatekeepers

  2. Directory gatekeepers

  3. Gateways (dial peers that are shut down are ignored)

VRC constructs routes based on dial peers. Ingress routes are created during the discovery process:

Similarly, egress routes are created during the discovery process:

During Discovery, if routes with similar parameters apply to all voice ports on a gateway, VRC combines them into one route on the gateway. Similarly, if routes with similar parameters apply to all gateways in a zone, VRC combines them into one route for the zone.

VRC maintains all route names and descriptions, and all route scope names and descriptions during discovery.

From a discovery design session you can:

Note: The first running configuration for all Discovered elements are stored in the origconfig directory, even if the VRC Discovery is discarded.
