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.
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 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 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, how to integrate the 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, also important collaboration concepts are demystified with Wireshark such as Firewall and NAT Traversal for MRA that you will not see elsewhere with atypical call flow, demysitifying one of the most complex and important concepts in collaboration which are STUN, TURN and ICE for NAT traversal through atypical call flow, why we started in the past with STUN then we moved to TURN and finally why we added ICE, I gone in depth through wireshark analysis to demystify each protocol and to understand why we jumped from STUN to TURN and finally ICE using L3/L4 encapsulation packet so that you definitely demystify this big topic.
This workbook is an HANDS ON LABS that can help you to prepare the CCNP Collaboration CLACCM and CLCNF Exam. Also It provide you as a voip administrator practice scenarios without useless theory but with a bunch and concise explanation and configuration guide from scratch.
