Dial Plan Call Routing Demystified Cisco Unified Communication Manager Kindle Format


Dial plan and Call Routing are the most important complex components for any Cisco Unified Communications system and deployment. Whether implementing single-site or multisite deployments, understanding the dial plan and Call Routing and the solid knowledge of how to implement them on Cisco Unified Communication Manager is essential for any voice engineer. Generally, the dial plan is the decision maker and instructs the call processing agent on how to route the calls.

Goals and Methods:

When we talk about Dial Plan and Call Routing, many components are involved such route pattern, route list, route group, trunk and gateway, also Translation Pattern and Transformation Pattern for digits manipulation of the called and calling parties.

This Book is written to demystify the Dial Plan and Call Routing, especially the components that are used to implement them with atypical scenarios, to show you how translation pattern works?, how transformation pattern works?, what is the difference between them?, where to implement them?, how and where to implement digit manipulations of the called and calling parties at different level? Under route pattern, route group, at the phone level with the external phone number mask, at the gateway level, also one of the most important parts of Dial Plan is the Globalized Call Routing or Unified Dial Plan using the +164 format, the globalization is covered in details and anwser the question: Why we need the Unified Dial Plan? And how some features such as device mobility, AAR (Automated Alternate Routing), Emergency Numbers, Class of Service and TEHO (Tail Hop End Off) are simplified.

The Dial Plan and Call Routing on Cisco Unified Communication Server are covered with atypical explanations and scenarios so that you will definitely get a feeling of, “This is how a call is routed”, and “This is how a feature works”.
