Configuring Globalized Call Routing in Cisco Unified Communications Manager

  • Sample Chapter is provided courtesy of Cisco Press.
  • Date: Aug 19, 2020.

This chapter covers the following topics:

  • Call Routing and Path Selection: This topic will examine Cisco Unified Communications Manager call-routing tools, such as route patterns, SIP route patterns, route groups, and route lists.

  • Digit Manipulation: This topic will explain how translation patterns, route patterns, and transformation patterns are used in the Cisco Unified Communications Manager to manipulate the dial plan when necessary.

Continuing the same thread of call routing discussed in the preceding chapter, this chapter discusses two other very important aspects to call routing. The idea of a globalized call-routing plan is to implement tools that will allow calls to be routed between Cisco Unified Communications Manager clusters within an enterprise network, route calls outside an enterprise network over IP, and route calls from an IP network out across the PSTN. Routing calls in so many different environments will inevitably require aliases to be manipulated from their original form. This concept of digit manipulation is also part of a globalized call-routing plan. Topics discussed in this chapter include the following:

  • Call Routing and Path Selection

    • Route Groups and Local Route Groups

    • Route Lists

    • Route Patterns and SIP Route Patterns

  • Digit Manipulation

    • Translation Patterns

    • Transformation Patterns

This chapter covers the following objectives from the Cisco Collaboration Core Technologies v1.0 (CLCOR 350-801) exam:

  • 4.3 Configure globalized call routing in Cisco Unified CM

    • 4.3.a Route patterns (traditional and +E.164 format)

    • 4.3.b Translation patterns

    • 4.3.c Standard local route group

    • 4.3.d Transforms

    • 4.3.e SIP route patterns
