Cisco Shell Schema Groups: Overview
-----------------------------------

To deploy your own existing dial plan rather than one of Cisco's
out-of-the-box dial plans, use the shell schema group to enable core
functionality without deploying a preconfigured VOSS-4-UC schema
group. The shell schema group provides a starting point for you to build
your own dial plan. The shell schema group has no preset site default
values other than Default Device Pool and Default CUCM Group. The shell
schema group does not contain any default core schemas, features schemas,
or country schemas. You can clone the shell schema group instance and
tailor all other settings to your own specifications.

On the Custom Workflows tab, the shell schema group provides default
workflows for the following registry events used to create customer
inventories and associations:

* addDnInventory - allows you to create DN inventory without enforcing
  any rules or constraints on the DN numbers
* addE164Inventory - allows you to create E164 inventory without
  enforcing any rules or constraints on the E164 number other than
  enforcing the country code prefix for a given site
* associateE164ToDn - allows E164 to DN number association (N to N) on
  VOSS-4-UC without configuring anything on Cisco Unified CM
* unassociateE164ToDn - removes E164 to DN number association (N to N)
  from VOSS-4-UC without removing anything on Cisco Unified CM
* associateE164ToSingleDn - allows E164 to DN number association (N to
  1) on VOSS-4-UC without configuring anything on Cisco Unified
  CM
* unassociateE164ToSingleDn - removes E164 to DN number association (N
  to 1) on VOSS-4-UC without removing anything on Cisco Unified
  CM

with customers, refer to the Provider HCS Dial Plan Management Support Guide.
