Overview
As part of the Wrangler WxC-DI Migration Dial plan Type Template - an option exist to select SDP (Simplified Dial Plan). This will enable the push of a Simplified country dial plan to the target WxC-DI server. The Source CUCM Dial Plan objects are then mapped to the pre provisioned dial plan and device objects transformed and migrated
The dial plan is created in wrangler using templates and libphone library. A dialplan instance will be automatically created / country and sites and , then pushed by Wrangler to the target as part of the migration
The existing SDP templates part of the Default Schema in Wrangler may be freely modified to suit or new created as required.
Migration with SDP Dial Plan
