About the VCS's directory service

The VCS's directory service is an on-box repository of dial plan information. It contains call routing
information and can provide registration and call policy services.
The directory service has no user configurable options on the VCS. The dial plan and policy information is
managed on a separate dial plan server and its contents are pushed out to all of its client VCSs. It is suited to
large-scale deployments where a centrally-managed system can provide a comprehensive directory of
aliases and their corresponding routing information.
You can configure the VCS to use the directory service in the following areas:
Registration restriction
n
Call Policy configuration: where it can be applied in addition to locally-defined Call Policy
n
Cisco VCS Administrator Guide (X7.2)
policies: as an alternative to using Allow and Deny Lists
