This chapter is from the book


Unified CVP has a significant amount of flexibility in how it is deployed as discovered in this chapter. The different functional deployment models discussed provide a simple set of architectural starting points for engineers to understand these deployments and to discuss their strengths and differences with their customers. This chapter also discussed interactions with Unified ICM to provide some basic integration concepts about the switch and VRU leg of a call and how Unified ICM deals with each.

In addition, this chapter provided a detailed overview of the different call flows supported by each function deployment model solidifying this knowledge for use in future chapters pertaining to high-availability designs and troubleshooting the solution. As mentioned earlier, it is critical that engineers understand the solutions components, different deployment models, and their respective call flows to have a solid base of solution architectural knowledge to build upon with more advanced features found in later chapters.

The next chapter explores how CVP handles different geographical deployments such as centralized and distributed branches. It also illustrates how a distributed branch or edge design can be accomplished using different techniques supported by Unified CVP with SIP and H.323. It also acknowledges the importance of understanding the geographical deployments supported by CVP and how to build high availability into each of these components depending on their geographical placement.
