Overview/Purpose

This chapter explores the connection of a Cisco Unified Communications Manager (CUCM) system to the public switched telephone network (PSTN) and branch offices. Configuring CUCM to route calls can be a complex endeavor, with many components involved. With the requirements to cover failover in the event of overloaded WAN links or hardware failure added to the design, the complexity increases even more. The labs in this chapter demonstrate the basics of call routing, failover, and call control.

Learning objectives:

  • Add devices to CUCM
  • Configure route groups in CUCM
  • Configure route lists in CUCM
  • Configure route patterns in CUCM
  • Understand call routing in CUCM
