Configuring Class of Restrictions

Chapter 9, "Dial Plans," listed the five components of a dial plan. This chapter focuses on implementing calling privileges. The calling privileges component of building a dial plan in a voice gateway is accomplished using Class of Restrictions (COR). COR is typically used in conjunction with Survivable Remote Site Telephony (SRST) or CallManager Express, but you can apply it to any dial peer on a voice gateway to restrict access.

This chapter helps you to do the following:

  • Understand how COR operates.
  • Use COR to restrict outbound and inbound calls in an SRST gateway.
  • Use COR to restrict outbound and inbound calls in a CallManager Express gateway.
  • Describe best practices for implementing COR.
