Voice Over IP Crash Course
Chapter 4: Validating the Existing Network
Chapter 4 of Voice Over IP Crash Course by Steven Shepard presents best practices for validating your existing network before implementing VoIP. Most enterprises have a significant investment in their communications infrastructure and do not want to lose the value of that investment. The evolution to a converged Internet Protocol (IP) architecture does not necessarily mean that the existing installed base must be completely replaced.
In this chapter, you will learn how to carefully craft a migration strategy, perform asset and capability inventories, decide what capabilities are required that your current network can not deliver and uncover tangible and intangible costs that can be mined out as a result of implementation. This chapter also covers the pre-assessment phase, the physical network, the logical network, network utilization, usage practices and policies.
