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.
Today, another challenge is emerging which is the conferencing, it becomes fundamental for work and business anywhere and anytime. at the history of Cisco about the conferencing solution provided in the past through MCU, Telepresence Server, Telepresence Conductor and the migration to an All-in-one solution with Cisco Meeting Server for on-premise solution and webex team for cloud solution show us the the race against time led by Cisco and prooves that video and web conference is now important for better business profitability.
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 part 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, this is why I call it Simplification.
In addition the Cisco Meeting Server components are demystified in details: Clustering, Certificates Requirements, Webbridge and CallBridge and how the Call Bridge Group feature provides intelligente load balancing with uncommon explanations, the dial plan and the call routing logic using the main tables on CMS, how the calls are processed by the Incoming Call Table, Call Forwarding Table and Outbound Call Table, the integration of Cisco CMS with different cisco collaborations components such as Cisco Unified Communication Manager with appropriate Dial Plan, Cisco Expressway Series to provide WebRTC connection for external user in an easy and secure fashion, integration with the Cisco Meeting Management and Cisco Telepresence Management Suite to provide scheduled conference and NFS server for recording.
The Dial Plan and Call Routing on Cisco Unified Communication Server and Cisco Meeting Server are covered with atypical and uncommon explanations, as you read this book, you definitely get a feeling of, “This is how a call is routed”, and “This is how a feature works”.
How to read this book?
This book is a series of hands of labs, and there is no relationship between them, you can start at any lab, from the last, the first or the middle, the purpose is to provide you a granularity to freely switch between topics and go to the one you need in depth lecture and understanding.
