About Dial Plan Setup
In Cisco Unified Communications Manager Administration, use the Installer menu path to configure dial plans.
You can install a Cisco International Dial Plan and use it to create a unique numbering plan that is specific to a country, other than one in North America. Cisco Unified Communications Manager provides North American Numbering Plan (NANP) by default. Because dial plan requirements of other countries are unique to those countries, the default NANP configuration may not be the best suited configuration to create a dial plan for those countries. Cisco International Dial Plan allows you to create and update unique dial plans and make them available for use to Cisco customers worldwide.
Before you install a dial plan on the server, you should download the equivalent dial plan COP (Cisco Option Package) file to the Cisco Unified Communications Manager server.
You can find COP files for all the available dial plans that you can download, install, and integrate with Cisco Unified Communications Manager systems on the Cisco website.
For details on installing a COP file, see the Cisco Unified Communications Manager Dial Plan Guide.
