Description

The dial plan is one of the key elements of an IP telephony system. It’s at the core of the user experience because it defines the rules that govern how a user reaches any destination. The most important components of a dial plan are endpoint addressing and path selection. Calling privileges are another important dial plan component. Calling privileges are used to implement class of service (CoS). Based on the calling device or line, some destinations are permitted to access call-routing table entries; other destinations are not.
This course describes endpoint addressing, digit analysis, and path selection in a Cisco Unified Communications Manager (CUCM) deployment and details the configuration tools that can be used to implement calling privileges and discusses different usage scenarios.
