Overview
A high-availability design provides the highest level of failure protection. Your solution may vary
depending upon business needs such as:
depending upon business needs such as:
•
Tolerance for call failure
•
Budget
•
Topological considerations
Unified CVP can be deployed in many configurations that use numerous hardware and software
components. Each solution must be designed in such a way that a failure impacts the fewest resources
in the call center. The type and number of resources impacted depends on how stringent the business
requirements are and which design characteristics you choose for the various Unified CVP components,
including the network infrastructure. A good Unified CVP design is tolerant of most failures (defined
later in this chapter), but sometimes not all failures can be made transparent to the caller.

Unified CVP is a sophisticated solution designed for mission-critical call centers. The success of any
Unified CVP deployment requires a team with experience in data and voice internet working, system
administration, and Unified CVP application configuration.

Before implementing Unified CVP, use careful preparation and design planning to avoid costly upgrades
or maintenance later in the deployment cycle. Always design for the worst possible failure scenario, with
future scalability in mind for all Unified CVP sites.
