National Numbering Plan Overview
Cisco Unified Communications Manager provides a default North American Numbering Plan (NANP). For countries with different dial plan requirements, you can install a Cisco International Dial Plan and use it to create a unique numbering plan that is specific to your requirements.
This chapter describes how to install a national numbering plan. For more information about using a national numbering plan, see the Cisco Unified Communications Manager Dial Plan Deployment Guide at http://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html.
