Description
IP telephony networks require seamless integration with the public switched telephone network (PSTN). With multiple call paths available, network administrators need to have an in-depth understanding of call routing in order to control the path that is taken for a particular call, and of course, to control call costs. A telephony class of service (CoS) implementation means that not all users can access all call routing table entries. The result is that for a specific calling device or line, some destinations are permitted while others are not.
This lesson describes an overview of call flows as well as the configuration components that impact call legs in Cisco Unified Communications Manager and Cisco Unified Communications Manager Express. The concept of calling privileges and how they can be implemented on Cisco Unified Communications Manager Express routers using class of restriction (COR) is also discussed.

Objective
