Implementing Telephony Call Restrictions and Control

This chapter covers the following topics:

  • Defining Class of Service as it relates to users of a phone system
  • Defining partitions and calling search spaces and identifying the components of each
  • Configuring partitions and calling search spaces in Cisco CallManager to assign calling privileges to users and devices
  • Defining time-of-day routing and identifying its uses and components
  • Configuring time-of-day routing to control call routing based on the time of day, day of week, and day of year when the call was made

An important dial plan consideration is the assignment and enforcement of calling privileges. You might want company executives to have different calling privileges than receptionists, or employee phones to have different calling privileges than lobby phones. You might also want to place further restrictions on the times that these privileges are available, for example, by allowing international calls to be placed only during business hours to prevent unauthorized use after hours. Partitions, calling search spaces, and time-of-day routing are the primary class of control components that enable you to assign and enforce calling privileges.

This chapter discusses how to deploy calling restrictions and control by using Cisco CallManager partitions, calling search spaces, and time-of-day routing.
